Hi,friends,
Thanks.

We boot the linux-2.6.22 on MPC8360 board, it failed, follow is the output
information. we just only success on linux-2.6.11, but fail on linux-2.6.19 and
linux-2.6.22. Both 2.6.19 and 2.6.22 are failed on same position,please see follow
information. linux-2.6.19 and linux-2.6.22 are come from BSP of freescale. I used
the u-boot-1.2.0 that compiled by myself. We guess that maybe we did not setup the
bootargs parameter on u-boot rightly or maybe the DDR-I hardware circuit design is
not good enough.

If the reason is the bootargs parameter, could you tell me what is the right
bootargs for linux-2.6.19 and linux-2.6.22?

If the reason is the DDR, I want to boot the linux on my SDRAM chip,kick off the
DDR, my SDRAM located on the address of F0000000~F3FFFFFF, total 64MB. How can I
modify the source code of linux to re-map it and ramdisk and others to my SDRAM
chip space?


Follow is the fail information:
