By default, the kernel for APF27 is the 2.6.29.6. Migration for the kernel upstream 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 a recent kernel with latest armadeus trunk on APF27.
With recent kernel it is also important to know how to use kernel device tree
mainline target
- Get the latest trunk version with command :
$ git clone git://git.code.sf.net/p/armadeus/code armadeus-trunk
- Configure the view for APF28 "mainline" :
$ cd armadeus-trunk $ make apf27mainline_defconfig
- Update your board:
BIOS> run update_uboot; reset BIOS> run flash_reset_env; reset BIOS> setenv fdt_addr_r A0008000 BIOS> saveenv BIOS> run update_dtb BIOS> run update_kernel BIOS> run update_rootfs
- Framebuffer can support multiple LCDs and so LCD you want to use must be passed as bootparam (like serial port). So you can do (for example):
BIOS> setenv console console=ttymxc0,115200 video=imxfb:Chimei-LW700AT9003
Evolution of migration
See Kernel-upstream-status to know the status of kernel migration.
