(<a href="https://github.com/postmarketOS/pmbootstrap/pull/158">#158</a>)</p> +<p>Once the device has been successfully initialized, enable it:</p> +<pre class="codehilite"><code>$ sudo ip link set wlan0 up +$ sudo iw wlan0 set type managed</code></pre> + + +<p>Configure wpa_supplicant (only necessary on encrypted networks):</p> +<pre class="codehilite"><code>$ sudo su - +# wpa_passphrase $YOUR_SSID > /etc/wpa_supplicant/wlan0.conf +<enter passphrase here and press Enter> +# exit</code></pre> + + +<p>Connect to network using wpa_supplicant:</p> +<pre class="codehilite"><code>$ sudo wpa_supplicant -Dwext -i wlan0 -c /etc/wpa_supplicant/wlan0.conf</code></pre> + + +<p>If your network uses DHCP, start the DHCP client:</p> +<pre class="codehilite"><code>$ sudo udhcpc -i wlan0</code></pre> + + +<h4>Keyboard Backlight</h4> +<p>There are 6 keyboard backlight LEDs that can be adjusted, they are found under <code>/sys/class/leds/lp5523:kb{1-6}</code>. To adjust brightness, write a value, $VAL between 0 and 255, to the <code>brightness</code> parameter as the root user:</p> +<pre class="codehilite"><code>for i in $(seq 1 6); + do echo $VAL > /sys/class/leds/lp5523\:kb$i/brightness +done</code></pre> + + +<h4>Boot partition within postmarketos</h4> +<p>The boot partition can be accessed within postmarketos by mounting <code>/dev/dm-0</code>. This allows performing kernel updates by installing the <code>linux-nokia-rx51</code> apk after mounting <code>/dev/dm-0</code> to <code>/boot</code>.</p> +<h4>Display</h4> +<p>With DRM enabled (<a href="https://github.com/postmarketOS/pmbootstrap/pull/197">#197</a>), the display can be managed at this location: <code>/sys/devices/platform/omapdrm.0/graphics/fb0/</code></p> +<h4>Keyboard layout in console</h4> +<p>In order to set the keyboard layout for the virtual console (e.g. to take advantage of number keys on the N900 keyboard), obtain your desired language keymap file for the RX-51, <a href="https://raw.githubusercontent.com/archlinuxarm-n900/n900-keymaps/master/rx51_us.map">such as this one.</a>. (TODO: Need to pull 'official' vconsole keymaps from Maemo5 if they exist..).</p> +<p>On the N900, install <code>kbd-bkeymaps</code>, either by using <code>pmbootstrap install --add kbd-bkeysmaps</code> on the host system or by running <code>apk add kbd-bkeysmaps</code> on the device itself.</p> +<p>The keymap must be in binary format, bmap. This can be accomplished using the <code>loadkeys</code> tool:</p> +<pre class="codehilite"><code class="language-bash">$ apk add kbd kbd-bkeymaps +$ loadkeys -b rx51_us.map > rx51_us.bmap +$ gzip rx51_us.bmap</code></pre> + + +<p>Compress it and copy it to <code>/usr/share/bkeymaps/us/</code> on the N900.</p> +<p>Log into the N900, and run <code>sudo setup-keymap</code>, then select <code>us</code> and finally <code>rx51_us</code>.</p> +<h4>Battery Capacity Reporting</h4> +<p>The current battery capacity can be found under <code>/sys/class/power_supply/bq27200-0/capacity</code>, and is represented as a percentage. For example, a value of <code>11</code> equates to <code>11%</code>. If <code>capacity</code> does not exist or contains erroneous information, then your battery needs to be calibrated first. To calibrate the battery:</p> +<p>1) Charge it up fully, using a wall power adapter.</p> +<p>2) Once it is charged up, power on the device</p> +<p>3) Unplug the device and allow the battery to run all the way down until it powers off. This may take quite a while to happen (>24hrs, but can be made shorter by running a CPU intensive workload)</p> +<p>4) When device powers off, plug it back into wall adapter and allow to charge up fully again. The battery and charging chip should now be calibrated.</p> +<h3>Helpful Links for Porting</h3> +<ul> +<li> +<p><a href="https://neo900.org/stuff/block-diagrams/n900/n900.html">Device schematic</a></p> +</li> +<li> +<p><a href="http://plan9.stanleylieber.com/hardware/n900/n900.schematics.pdf">Very detailed schematic</a></p> +</li> +<li> +<p><a href="https://github.com/archlinuxarm-n900/alarm-n900/wiki/Hardware-support">Arch Linux ARM - N900 hardware components list</a></p> +</li> +<li> +<p><a href="http://mlab.taik.fi/paja/?p=1263">N900 sensor access in Maemo</a></p> +</li> +<li> +<p><a href="http://natisbad.org/N900/n900-commented-hardware-specs.html">Hardware component specs / list</a></p> +</li> +</ul> + + </div> + </div> + </body> +</html>
