By default, the kernel for APF28 is the 2.6.35 version (from Freescale BSP). Migration to Mainline (3.6) is in progress but not finished, this article explains how to use (test) these kernels with latest armadeus trunk.

Mainline support is done with Device Tree.

Get the trunk version

  • Get the latest trunk version with command :
$ git clone git://git.code.sf.net/p/armadeus/code armadeus-trunk
  • Configure the view for APF28 :
$ cd armadeus-trunk
$ make apf28_defconfig
  • On menuconfig select :
Toolchain  --->
    Kernel Headers (Linux 2.6 (manually specified version))  --->
    (3.6.2) linux version
...
System configuration  --->
    (ttyAMA0) Port to run a getty (login prompt) on
...
Kernel  --->
    (3.6.2) Kernel version
    (../patches/linux/$(BR2_LINUX_KERNEL_VERSION)) Custom kernel patches
  • Then build :
$ make

U-Boot modification

  • Serial port used for console has now a different name: ttyAMA0. So if you want to see something on your serial console please do the following before booting: 
BIOS> setenv console console=ttyAMA0,115200n8

BIOS> setenv consoledev ttyAMA0
BIOS> run nfsboot

Which devices are supported ?
