Hi:
My board is a custom MPC8260 board, with 4MB flash,128MB SDRAM.
I modified pq2fads.dts and pq2fads_defconfig,
then compile the kernel.The kernel halt after displaying "Booting using OF flat
tree.".
Serial Console:

I have no idea about this,
u-boot,Flat device tree ,kernel,Ramdisk ,Thatwas wrong??
Best regards.
