Hello,
2011/10/2 webwillow@thewebwillow.com:
Can anyone provide me with a little insight to configuring a feescale M53 device to boot to another kernel...
I do $ sudo dd if=uImage of=/dev/$device bs=1M seek=1
then load 0x2000, something like: mmc read 0 ${loadaddr} 0x800 0x2000; bootm
But, surely you can configure the bootloader to read from a filesystem instead.
Best regards,

Your default boot commant is not very friendly, loading the kernel from raw blocks on the mmc controller (sd card etc).
bootcmd_mmc=run bootargs_base bootargs_mmc; mmc read 0 ${loadaddr} 0x800 0x1800; bootm bootcmd=run bootcmd_mmc
I would recommend you make a new bootcmd_ext2 which uses ext2load to load the kernel. Much easier to change kernel that way. Then change bootcmd to refer to that one when verified working.
