Kernel Hang :uncompressed kernel

[akilkumar]

Hi ,

We are Porting Linux-3.0.6 Kernel on our VPX- P2020 Board. I am loading Kernel and filesystem image through tftp to some Ram location and trying to boot it. Kernel prints "Bad Data CRC" error

WARNING: adjusting available memory to 30000000
## Booting kernel from Legacy Image at 01000000 ...
Image Name: Linux-3.0.6

Entry Point: 00000000

I tried to ignore CRC check and boot the kernel by setting this command

setenv verify 'n'

But this dint work well .My kernel got hang at this message

Can anyone help me to solve this issue.

Hi

The purpose of the CRC is to check the kernel is valid or not. When you get a CRC error, you must try to solve this issue instead of avoiding it. Many solutions.
-check the kernel you load from tftp is correct
-check your tftp link is reliable
-check your board doesn't have a memory (or other hardware) failure
