Firstly, I have already change the init_mx28.c in boot prep to fit my custom board. And also, I have already modify some code in power prep.
Currently, I can flash uboot in SD card and then download the kernel via tftp, mount rootfs via nfs successfully.
The problem is, when I flash imx28_ivt_linux.sb to SD card, it stops at
Uncompressing linux..........done, booting the kernel.
The common reason for this might be arch number wrong, which is unlikely.
Therefore, I believe I need to change something in linux prep. Anyone have any ideas?
