[meta-ti] Building and booting AM335x Starter Kit

Mon May 6 02:16:13 PDT 2013

Hi,
I'm currently trying out the meta-ti layer on an AM335x EVM Starter Kit (not the regular am335x-evm). As far as I can see the meta-ti layer's machine configuration for am335x-evm should work also on the am335x-evmsk. But I'm having trouble booting the device after doing a build.

The x-loader and u-boot stages works alright and the kernel is loaded. But during kernel boot the system hangs with the following statement
[    1.963153] Waiting for root device /dev/mmcblk0p2...
I have been reading up on dtb files and how they are managed by the ti-staging-kernel, and as long as I can see the correct one (am335x-evmsk.dtb) are included in the kernel and have all the device configurations needed.

Are there any known problems with this machine configuration, or have I missed some important stage? Any help or point in the right direction is highely appreciated. :-)

Thanks,
// Måns
