| − | By default, the kernel for APF27 is the 2.6.29.6. Migration for 2.6.38.x [[APF9328_and_APF27_migration_to_Linux_2.6.38 | is in progress]] but not finished, and some features like [[CAN]] or [[GPIOlib]] interrupts management are not available under kernel 2.6.29. This article explain how to use the 2.6.38.x kernel with latest armadeus trunk.

| − | Get the latest trunk version with command :
| + | |
| − | <pre class="host">

| − | $ git clone git://armadeus.git.sourceforge.net/gitroot/armadeus/armadeus apf27

| − | Configure the view for APF27 :

| − | == U-Boot modification ==
| + | |
| − | | + | |
| − | Serial port names have been unified to /dev/ttymxc[0-6]. So if you want to see something on your serial console please do the following before booting:
| + | |
| − | <pre class="apf">
| + | |
| − | BIOS> setenv console console=ttymxc0,115200
| + | |
| − | </pre>
| + | |
| − | | + | |
| − | * Framebuffer can now support multiple LCDs and so LCD you want to use must be passed as bootparam (like serial port). So you can do (for example):
| + | |
| − | <pre class="apf">
| + | |
| − | BIOS> setenv console console=ttymxc0,115200 video=imxfb:Chimei-LW700AT9003
| + | |
| − | </pre>
