Boot Loader Demo 1 (boot_demo1)

+//! +//! An example to demonstrate the use of a flash-based boot loader. At +//! startup, the application will configure the UART and USB peripherals, +//! and then branch to the boot loader to await the start of an +//! update. If using the serial boot loader (boot_serial), the UART will +//! always be configured at 115,200 baud and does not require the use of +//! auto-bauding. +//! +//! This application is intended for use with any of the three flash-based boot +//! loader flavors (boot_serial or boot_usb) included in the software +//! release. To accommodate the largest of these (boot_usb), the link address +//! is set to 0x2800. If you are using serial, you may change this +//! address to a 1KB boundary higher than the last address occupied +//! by the boot loader binary as long as you also rebuild the boot +//! loader itself after modifying its bl_config.h file to set APP_START_ADDRESS +//! to the same value. +//! +//! The boot_demo2 application can be used along with this application to +//! easily demonstrate that the boot loader is actually updating the on-chip +//! flash. +//! +//! Note that the LM4F232 and other Blizzard-class devices also +//! support the serial and USB boot loaders in ROM. To make use of this +//! function, link your application to run at address 0x0000 in flash and enter +//! the bootloader using the ROM_UpdateSerial and ROM_UpdateUSB functions +//! (defined in rom.h). This mechanism is used in the utils/swupdate.c +//! module when built specifically targeting a suitable Blizzard-class device. +// +//***************************************************************************** + +//***************************************************************************** +// +// Graphics context used to show text on the CSTN display. +// +//***************************************************************************** +tContext g_sContext; + +//***************************************************************************** +// +// The error routine that is called if the driver library encounters an error. +// +//***************************************************************************** +#ifdef DEBUG +void +__error__(char *pcFilename, uint32_t ui32Line) +{ +} +#endif + +//***************************************************************************** +// +// Passes control to the bootloader and initiates a remote software update. +// +// This function passes control to the bootloader and initiates an update of +// the main application firmware image via UART0 or USB depending +// upon the specific boot loader binary in use. +// +// \return Never returns. +// +//***************************************************************************** +void +JumpToBootLoader(void) +{ + // + // Disable all processor interrupts.

At +startup, the application will configure the UART and USB peripherals, +and then branch to the boot loader to await the start of an +update. If using the serial boot loader (boot_serial), the UART will +always be configured at 115,200 baud and does not require the use of +auto-bauding. + +This application is intended for use with any of the three flash-based boot +loader flavors (boot_serial or boot_usb) included in the software +release. To accommodate the largest of these (boot_usb), the link address +is set to 0x2800. If you are using serial, you may change this +address to a 1KB boundary higher than the last address occupied +by the boot loader binary as long as you also rebuild the boot +loader itself after modifying its bl_config.h file to set APP_START_ADDRESS +to the same value. + +The boot_demo2 application can be used along with this application to +easily demonstrate that the boot loader is actually updating the on-chip +flash. + +Note that the LM4F232 and other Blizzard-class devices also +support the serial and USB boot loaders in ROM. To make use of this +function, link your application to run at address 0x0000 in flash and enter +the bootloader using the ROM_UpdateSerial and ROM_UpdateUSB functions +(defined in rom.h). This mechanism is used in the utils/swupdate.c +module when built specifically targeting a suitable Blizzard-class device. + +------------------------------------------------------------------------------- + +Copyright (c) 2012-2014 Texas Instruments Incorporated.

Boot Loader Demo 2 (boot_demo2)

+//! +//! An example to demonstrate the use of a flash-based boot loader. At startup, +//! the application will configure the UART, USB and Ethernet peripherals, wait +//! for a widget on the screen to be pressed, and then branch to the boot +//! loader to await the start of an update. If using the serial boot loader +//! (boot_serial), the UART will always be configured at 115,200 baud and does +//! not require the use of auto-bauding. +//! +//! This application is intended for use with any of the three flash-based boot +//! loader flavors (boot_eth, boot_serial or boot_usb) included in the software +//! release. To accommodate the largest of these (boot_usb), the link address +//! is set to 0x2800. If you are using serial or Ethernet boot loader, you +//! may change this address to a 1KB boundary higher than the last address +//! occupied by the boot loader binary as long as you also rebuild the boot +//! loader itself after modifying its bl_config.h file to set APP_START_ADDRESS +//! to the same value. +//! +//! The boot_demo1 application can be used along with this application to +//! easily demonstrate that the boot loader is actually updating the on-chip +//! flash. +//! +//! Note that the LM4F232 and other Blizzard-class devices also the +//! support serial and USB boot loaders in ROM. To make use of this +//! function, link your application to run at address 0x0000 in flash and enter +//! the bootloader using either the ROM_UpdateUSB or ROM_UpdateSerial +//! functions (defined in rom.h). This mechanism is used in the +//! utils/swupdate.c module when built specifically targeting a suitable +//! Blizzard-class device. +// +//***************************************************************************** + +//***************************************************************************** +// +// The number of SysTick ticks per second. +// +//***************************************************************************** +#define TICKS_PER_SECOND 100 + +//***************************************************************************** +// +// A global we use to keep track of when the user presses the "Update now" +// button. +// +//***************************************************************************** +volatile bool g_bFirmwareUpdate = false; + +//***************************************************************************** +// +// Buffers used to hold the Ethernet MAC and IP addresses for the board. +// +//***************************************************************************** +#define SIZE_MAC_ADDR_BUFFER 32 +#define SIZE_IP_ADDR_BUFFER 32 +int8_t g_pi8MACAddr[SIZE_MAC_ADDR_BUFFER]; +int8_t g_pi8IPAddr[SIZE_IP_ADDR_BUFFER]; + +//***************************************************************************** +// +// The error routine that is called if the driver library encounters an error. +// +//***************************************************************************** +#ifdef DEBUG +void +__error__(char *pcFilename, uint32_t ui32Line) +{ +} +#endif + +//***************************************************************************** +// +// Passes control to the bootloader and initiates a remote software update. +// +// This function passes control to the bootloader and initiates an update of +// the main application firmware image via UART0, Ethernet or USB depending +// upon the specific boot loader binary in use. +// +// \return Never returns. +// +//***************************************************************************** +void +JumpToBootLoader(void) +{ + // + // We must make sure we turn off SysTick and its interrupt before entering + // the boot loader! + // + ROM_SysTickIntDisable(); + ROM_SysTickDisable(); + + // + // Disable all processor interrupts.

At startup, +the application will configure the UART, USB and Ethernet peripherals, wait +for a widget on the screen to be pressed, and then branch to the boot +loader to await the start of an update. If using the serial boot loader +(boot_serial), the UART will always be configured at 115,200 baud and does +not require the use of auto-bauding. + +This application is intended for use with any of the three flash-based boot +loader flavors (boot_eth, boot_serial or boot_usb) included in the software +release. To accommodate the largest of these (boot_usb), the link address +is set to 0x2800. If you are using serial or Ethernet boot loader, you +may change this address to a 1KB boundary higher than the last address +occupied by the boot loader binary as long as you also rebuild the boot +loader itself after modifying its bl_config.h file to set APP_START_ADDRESS +to the same value. + +The boot_demo1 application can be used along with this application to +easily demonstrate that the boot loader is actually updating the on-chip +flash. + +Note that the LM4F232 and other Blizzard-class devices also the +support serial and USB boot loaders in ROM. To make use of this +function, link your application to run at address 0x0000 in flash and enter +the bootloader using either the ROM_UpdateUSB or ROM_UpdateSerial +functions (defined in rom.h). This mechanism is used in the +utils/swupdate.c module when built specifically targeting a suitable +Blizzard-class device. + +------------------------------------------------------------------------------- + +Copyright (c) 2008-2014 Texas Instruments Incorporated.

The +// widget presents the menus using a "sliding" animation. The menu items +// are shown in a vertical list, and as the user scrolls through the list +// of menu items, the menu slides up and down the display. When a menu item +// is selected to descend in the menu tree, the widget slides the old menu +// off the to left while the new menu slides in from the right. Likewise, +// going up in the menu tree, the higher level menu slides back onto the +// screen from the left. +// +// Additional structures are provided to implement a menu, and menu items. +// Each menu contains menu items, and each menu item can have a child menu. +// These structures can be used to build a menu tree. The menu widget will +// show one menu at any given time, the menu that is displayed on the screen. +// +// In addition to child menus, any menu item can have instead a child widget. +// If this is used, then when the user selects a menu item, a new widget can +// be activated to perform some function. When the function of the child +// widget completes, then the widget slides back off the screen (to the right) +// and the parent menu is displayed again. +// +// A given menu can have menu items that are individually selectable or +// multiple-selectable. For individually selectable menu items, the item +// is selected by leaving the menu with the focus on the selected item. For +// example navigating down to a submenu with choices A, B and C, and then +// navigating until the focus is on item B will cause item B to be selected. +// The menu will remember that item B was selected even when navigating away +// from that menu. +// +// If a menu is configured to be multiple-selectable, then each menu item has +// a check box that is checked by pressing the select button. When the item +// is selected the box will show an X. Any or all or none can be selected in +// this way. When a menu is configured to be multi-selectable, the menu items +// cannot have any child menus or widgets. +// +// The menu widget provides some visual clues to the user about how to +// navigate the menu tree. Whenever a menu item has a child menu or child +// widget, then a small right arrow is shown on the right side of the menu +// item that has the focus. This tells the user to press the "right" button +// to descend to the next menu or widget. When it is possible to go up a +// level in the menu tree (when showing a child menu), a small left arrow +// will be shown on the menu item with the focus. This is an indication to the +// user that they should press the "left" button. +// +// This widget is meant to work with key/button presses. It expects there +// to be up/down/left/right and select buttons. The widget will need to be +// modified in order to work with a pointer input. +// +// In order to perform the sliding animation, the menu widget requires that +// it be provided with two off-screen displays. The menu widget renders the +// two menus (the old and the new) into the two buffers, and then repeatedly +// paints both to the physical display while adjusting the coordinates as +// appropriate. This will cause the menus to appear animated and move across +// the display. When the menus are being animated, the menu widget is taking +// all the non-interrupt processor time in order to draw the buffers to the +// display. This operation occurs in response to the widget processing of the +// key/button events and will occur in the thread that calls +// WidgetMessageQueueProcess(). The programmer should be aware of this +// processing burden when designing an application that uses the sliding +// menu widget. +// +//***************************************************************************** + +//***************************************************************************** +// +// A graphics image of a small right arrow icon. +// +//***************************************************************************** +const uint8_t g_ui8RtArrow[] = +{ + IMAGE_FMT_1BPP_UNCOMP, + 4, 0, + 8, 0, + + 0x80, + 0xC0, + 0xE0, + 0xF0, + 0xE0, + 0xC0, + 0x80, + 0 +}; + +//***************************************************************************** +// +// A graphics image of a small left arrow icon. +// +//***************************************************************************** +const uint8_t g_ui8LtArrow[] = +{ + IMAGE_FMT_1BPP_UNCOMP, + 4, 0, + 8, 0, + + 0x10, + 0x30, + 0x70, + 0xF0, + 0x70, + 0x30, + 0x10, + 0 +}; + +//***************************************************************************** +// +// A graphics image of a small unchecked box icon. +// +//***************************************************************************** +const uint8_t g_ui8Unchecked[] = +{ + IMAGE_FMT_1BPP_UNCOMP, + 7, 0, + 8, 0, + + 0xFE, + 0x82, + 0x82, + 0x82, + 0x82, + 0x82, + 0xFE, + 0 +}; + +//***************************************************************************** +// +// A graphics image of a small checked box icon. +// +//***************************************************************************** +const uint8_t g_ui8Checked[] = +{ + IMAGE_FMT_1BPP_UNCOMP, + 7, 0, + 8, 0, + + 0xFE, + 0xC6, + 0xAA, + 0x92, + 0xAA, + 0xC6, + 0xFE, + 0 +}; + +//***************************************************************************** +// +//!

Hibernate Example (hibernate)

+//! +//! An example to demonstrate the use of the Hibernation module. The user +//! can put the microcontroller in hibernation by pressing the select +//! button.

Hibernation module so that it can be retrieved when the microcontroller +//! wakes. +// +//***************************************************************************** + +//***************************************************************************** +// +// Macros to convert character based display rows and columns into the pixel +// based X and Y coordinates needed for display drawing functions. +// +//***************************************************************************** +#define Col(c) ((c) * 6) +#define Row(r) ((r) * 8) + +//***************************************************************************** +// +// A counter that counts the number of ticks of the SysTick interrupt. +// +//***************************************************************************** +volatile uint32_t g_ui32SysTickCount = 0; + +//***************************************************************************** +// +// A buffer to hold character strings that will be printed to the display. +// +//***************************************************************************** +static char g_pcBuf[40]; + +//***************************************************************************** +// +// Text that will be displayed if there is an error. +// +//***************************************************************************** +static char *g_pcErrorText[] = +{ + "The controller", + "did not enter", + "hibernate mode.", + "---------------------", + " PRESS BUTTON", + " TO RESTART", + 0 +}; + +//***************************************************************************** +// +// A flag to indicate the select button was pressed. +// +//***************************************************************************** +static volatile bool bSelectPressed = 0; + +//***************************************************************************** +// +// The error routine that is called if the driver library encounters an error. +// +//***************************************************************************** +#ifdef DEBUG +void +__error__(char *pcFilename, uint32_t ui32Line) +{ +} +#endif + +//***************************************************************************** +// +// Delay a certain number of SysTick timer ticks. +// +//***************************************************************************** +void +SysTickWait(uint32_t ui32Ticks) +{ + ui32Ticks += g_ui32SysTickCount; + while(g_ui32SysTickCount <= ui32Ticks) + { + } +} + +//***************************************************************************** +// +// The SysTick handler.

With increasing +//! priorities, preemption will occur; in the other two cases tail-chaining +//! will occur.

Data Logger (qs-logger)

+//! +//! This example application is a data logger. It can be configured to collect +//! data from up to 10 data sources. The possible data sources are: +//! - 4 analog inputs, 0-20V +//! - 3-axis accelerometer +//! - internal and external temperature sensors +//! - processor current consumption +//! +//! The data logger provides a menu navigation that is operated by the buttons +//! on the EK-LM4F232 board (up, down, left, right, select). The data logger +//! can be configured by using the menus. The following items can be +//! configured: +//! - data sources to be logged +//! - sample rate +//! - storage location +//! - sleep modes +//! - clock +//! +//! Using the data logger: +//! +//! Use the CONFIG menu to configure the data logger. The following choices +//! are provided: +//! +//! - CHANNELS - enable specific channels of data that will be logged +//! - PERIOD - select the sample period +//! - STORAGE - select where the collected data will be stored: +//! - FLASH - stored in the internal flash memory +//! - USB - stored on a connected USB memory stick +//! - HOST PC - transmitted to a host PC via USB OTG virtual serial port +//! - NONE - the data will only be displayed and not stored +//! - SLEEP - select whether or not the board sleeps between samples. Sleep +//! mode is allowed when storing to flash at with a period of 1 second or +//! longer. +//! - CLOCK - allows setting of internal time-of-day clock that is used for +//! time stamping of the sampled data +//! +//! Use the START menu to start the data logger running. It will begin +//! collecting and storing the data. It will continue to collect data until +//! stopped by pressing the left button or select button. +//! +//! While the data logger is collecting data and it is not configured to +//! sleep, a simple strip chart showing the collected data will appear on the +//! display. If the data logger is configured to sleep, then no strip chart +//! will be shown. +//! +//! If the data logger is storing to internal flash memory, it will overwrite +//! the oldest data. If storing to a USB memory device it will store data +//! until the device is full. +//! +//! The VIEW menu allows viewing the values of the data sources in numerical +//! format. When viewed this way the data is not stored. +//! +//! The SAVE menu allows saving data that was stored in internal flash memory +//! to a USB stick. The data will be saved in a text file in CSV format. +//! +//! The ERASE menu is used to erase the internal memory so more data can be +//! saved. +//! +//! When the EK-LM4F232 board running qs-logger is connected to a host PC via +//! the USB OTG connection for the first time, Windows will prompt for a device +//! driver for the board. +//! This can be found in /ti/TivaWare_C_Series-x.x/windows_drivers +//! assuming you installed the software in the default folder. +//! +//! A companion Windows application, logger, can be found in the +//! /ti/TivaWare_C_Series-x.x/tools/bin directory. When the data logger's +//! STORAGE option is set to "HOST PC" and the board is connected to a PC +//! via the USB OTG connection, captured data will be transfered back to the PC +//! using the virtual serial port that the EK board offers. When the logger +//! application is run, it will search for the first connected EK-LM4F232 board +//! and display any sample data received.

USB Generic Bulk Device (usb_dev_bulk)

+//! +//! This example provides a generic USB device offering simple bulk data +//! transfer to and from the host. The device uses a vendor-specific class ID +//! and supports a single bulk IN endpoint and a single bulk OUT endpoint. +//! Data received from the host is assumed to be ASCII text and it is +//! echoed back with the case of all alphabetic characters swapped. +//! +//! A Windows INF file for the device is provided on the installation CD and +//! in the C:/ti/TivaWare_C_Series-x.x/windows_drivers directory of TivaWare +//! releases. This INF contains information required to install the WinUSB +//! subsystem on WindowsXP and Vista PCs. WinUSB is a Windows subsystem +//! allowing user mode applications to access the USB device without the need +//! for a vendor-specific kernel mode driver. +//! +//! A sample Windows command-line application, usb_bulk_example, illustrating +//! how to connect to and communicate with the bulk device is also provided. +//! The application binary is installed as part of the ``TivaWare for C Series +//! PC Companion Utilities'' package (SW-TM4C-USB-WIN) on the installation CD +//! or via download from http://www.ti.com/tivaware . Project files are +//! included to allow the examples to be built using +//! Microsoft Visual Studio 2008. Source code for this application can be +//! found in directory ti/TivaWare_C_Series-x.x/tools/usb_bulk_example. +// +//***************************************************************************** + +//***************************************************************************** +// +// The system tick rate expressed both as ticks per second and a millisecond +// period. +// +//***************************************************************************** +#define SYSTICKS_PER_SECOND 100 +#define SYSTICK_PERIOD_MS (1000 / SYSTICKS_PER_SECOND) + +//***************************************************************************** +// +// The global system tick counter. +// +//***************************************************************************** +volatile uint32_t g_ui32SysTickCount = 0; + +//***************************************************************************** +// +// Variables tracking transmit and receive counts. +// +//***************************************************************************** +volatile uint32_t g_ui32TxCount = 0; +volatile uint32_t g_ui32RxCount = 0; +#ifdef DEBUG +uint32_t g_ui32UARTRxErrors = 0; +#endif + +//***************************************************************************** +// +// Debug-related definitions and declarations. +// +// Debug output is available via UART0 if DEBUG is defined during build. +// +//***************************************************************************** +#ifdef DEBUG +//***************************************************************************** +// +// Map all debug print calls to UARTprintf in debug builds. +// +//***************************************************************************** +#define DEBUG_PRINT UARTprintf + +#else + +//***************************************************************************** +// +// Compile out all debug print calls in release builds. +// +//***************************************************************************** +#define DEBUG_PRINT while(0) ((int32_t (*)(char *, ...))0) +#endif + +//***************************************************************************** +// +// Graphics context used to show text on the color LCD display. +// +//***************************************************************************** +tContext g_sContext; + +//***************************************************************************** +// +// Flags used to pass commands from interrupt context to the main loop. +// +//***************************************************************************** +#define COMMAND_PACKET_RECEIVED 0x00000001 +#define COMMAND_STATUS_UPDATE 0x00000002 + +volatile uint32_t g_ui32Flags = 0; +char *g_pcStatus; + +//***************************************************************************** +// +// Global flag indicating that a USB configuration has been set. +// +//***************************************************************************** +static volatile bool g_bUSBConfigured = false; + +//***************************************************************************** +// +// The error routine that is called if the driver library encounters an error. +// +//***************************************************************************** +#ifdef DEBUG +void +__error__(char *pcFilename, uint32_t ui32Line) +{ + UARTprintf("Error at line %d of %s\n", ui32Line, pcFilename); + while(1) + { + } +} +#endif + +//***************************************************************************** +// +// Interrupt handler for the system tick counter. +// +//***************************************************************************** +void +SysTickIntHandler(void) +{ + // + // Update our system tick counter. + // + g_ui32SysTickCount++; +} + +//***************************************************************************** +// +// Receive new data and echo it back to the host. +// +// \param psDevice points to the instance data for the device whose data is to +// be processed. +// \param pi8Data points to the newly received data in the USB receive buffer. +// \param ui32NumBytes is the number of bytes of data available to be processed. +// +// This function is called whenever we receive a notification that data is +// available from the host.

Care +should be taken to ensure that the active window can safely receive the +text; enter is not pressed at any point so no actions are attempted by the +host if a terminal window is used (for example). The status LED is used to +indicate the current Caps Lock state and is updated in response to any +other keyboard attached to the same USB host system. + +The device implemented by this application also supports USB remote wakeup +allowing it to request the host to reactivate a suspended bus. If the bus +is suspended (as indicated on the application display), pressing the +push button will request a remote wakeup assuming the host has not +specifically disabled such requests. + + +------------------------------------------------------------------------------- + +Copyright (c) 2011-2014 Texas Instruments Incorporated.

USB HID Keyboard Device (usb_dev_keyboard)

+//! +//! This example application turns the evaluation board into a USB keyboard +//! supporting the Human Interface Device class. When the push button is +//! pressed, a sequence of key presses is simulated to type a string. Care +//! should be taken to ensure that the active window can safely receive the +//! text; enter is not pressed at any point so no actions are attempted by the +//! host if a terminal window is used (for example). The status LED is used to +//! indicate the current Caps Lock state and is updated in response to any +//! other keyboard attached to the same USB host system. +//! +//!

USB Serial Device (usb_dev_serial)

+//! +//! This example application turns the evaluation kit into a virtual serial +//! port when connected to the USB host system. The application supports the +//! USB Communication Device Class, Abstract Control Model to redirect UART0 +//! traffic to and from the USB host system. +//! +//! Assuming you installed TivaWare in the default directory, a +//! driver information (INF) file for use with Windows XP, Windows Vista and +//! Windows7 can be found in C:/ti/TivaWare_C_Series-x.x/windows_drivers. +//! For Windows 2000, the required INF file is in +//! C:/ti/TivaWare_C_Series-x.x/windows_drivers/win2K. +// +//***************************************************************************** + +//***************************************************************************** +// +// Note: +// +// This example is intended to run on Tiva C Series evaluation kit hardware +// where the UARTs are wired solely for TX and RX, and do not have GPIOs +// connected to act as handshake signals.

It reports DSR, DCD +// and CTS as high to ensure that the USB host recognizes that data can be +// sent and merely ignores the host's requested DTR and RTS states.

example to demonstrate the use of the flash-based USB stick update +program. This example is meant to be loaded into flash memory from a USB +memory stick, using the USB stick update program (usb_stick_update), +running on the microcontroller. + +After this program is built, the binary file (usb_stick_demo.bin), should +be renamed to the filename expected by usb_stick_update ("FIRMWARE.BIN" by +default) and copied to the root directory of a USB memory stick. Then, +when the memory stick is plugged into the eval board that is running the +usb_stick_update program, this example program will be loaded into flash +and then run on the microcontroller. + +This program simply displays a message on the screen and prompts the user +to press the select button. Once the button is pressed, control is passed +back to the usb_stick_update program which is still is flash, and it will +attempt to load another program from the memory stick.

USB Stick Update Demo (usb_stick_demo)

+//! +//! An example to demonstrate the use of the flash-based USB stick update +//! program. This example is meant to be loaded into flash memory from a USB +//! memory stick, using the USB stick update program (usb_stick_update), +//! running on the microcontroller. +//! +//! After this program is built, the binary file (usb_stick_demo.bin), should +//! be renamed to the filename expected by usb_stick_update ("FIRMWARE.BIN" by +//! default) and copied to the root directory of a USB memory stick. Then, +//! when the memory stick is plugged into the eval board that is running the +//! usb_stick_update program, this example program will be loaded into flash +//! and then run on the microcontroller. +//! +//! This program simply displays a message on the screen and prompts the user +//! to press the select button. Once the button is pressed, control is passed +//! back to the usb_stick_update program which is still is flash, and it will +//! attempt to load another program from the memory stick. This shows how +//! a user application can force a new firmware update from the memory stick. +// +//***************************************************************************** + +//***************************************************************************** +// +// The error routine that is called if the driver library encounters an error. +// +//***************************************************************************** +#ifdef DEBUG +void +__error__(char *pcFilename, uint32_t ui32Line) +{ +} +#endif + +//***************************************************************************** +// +// Demonstrate the use of the USB stick update example. +// +//***************************************************************************** +int +main(void) +{ + uint_fast32_t ui32Count; + tContext sContext; + tRectangle sRect; + + // + // Enable lazy stacking for interrupt handlers.

USB Memory Stick Updater (usb_stick_update)

+//! +//! This example application behaves the same way as a boot loader. It resides +//! at the beginning of flash, and will read a binary file from a USB memory +//! stick and program it into another location in flash. Once the user +//! application has been programmed into flash, this program will always start +//! the user application until requested to load a new application. +//! +//! When this application starts, if there is a user application already in +//! flash (at \b APP_START_ADDRESS), then it will just run the user application. +//! It will attempt to load a new application from a USB memory stick under +//! the following conditions: +//! +//! - no user application is present at \b APP_START_ADDRESS +//! - the user application has requested an update by transferring control +//! to the updater +//! - the user holds down the eval board push button when the board is reset +//! +//! When this application is attempting to perform an update, it will wait +//! forever for a USB memory stick to be plugged in. Once a USB memory stick +//! is found, it will search the root directory for a specific file name, which +//! is \e FIRMWARE.BIN by default. This file must be a binary image of the +//! program you want to load (the .bin file), linked to run from the correct +//! address, at \b APP_START_ADDRESS. +//! +//! The USB memory stick must be formatted as a FAT16 or FAT32 file system +//! (the normal case), and the binary file must be located in the root +//! directory. Other files can exist on the memory stick but they will be +//! ignored. +// +//***************************************************************************** + +//***************************************************************************** +// +// The name of the binary firmware file on the USB stick.
