Hi,
I'm working on a custom MPC8313 board. It was booting up fine using NOR
flash and ext2 filesystem.
Configured u-boot and Linux and made transition to use NAND flash and
JFFS2 filesystem and now system hangs when running Linux kernel.
I've tried different things but I'm stuck.
Thanks in advance for any help.
