Boot Loader Demo 2 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. ------------------------------------------------------------------------------- Copyright (c) 2008-2014 Texas Instruments Incorporated.
