[meta-freescale] imx28evk based board moving from fido to jethro stopped to fully boot

[justin chaise]

Hi, I am working with a board that is almost the same as the imx23evk, the
imx28evk sibling.
It seems that not all of our, MXS family, drivers were ported to the newer
kernels.
If fido booted and you saw a login on the lcd you may be in good shape.

When you see the penguin logo that is the bootloader, u-boot, initializing
the hardware.
If the screen goes away after that; linux is not using or initializing the
lcd. It may be using the serial port.
First I would check the linux kernel command line switches in your device
tree under chosen --> bootargs.
Compare that to the settings you used with fido (linux-fslc 3.18?)
Second check the boot arguments in u-boot. These settings will overwrite
the command line switches from your device tree.
I you can not type at the command line in u-boot, you can change the boot
arguments in the code then recompile u-boot
see (include/configs/mx28evk.h)
I hope this starts you in the right direction.
