iMx51 - Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,1)

[FrancescoNamuri]

Hi,

I'm trying to upgrade my kernel to 2.6.35 patched by freescale, but I'm always getting the same error. it  recognizes the partition table, but it's like it doesn't handle the filesystem. I tried different SD cards... Same problem.

Can someone suggest me something to solve this issue?

thanks in advance.

Francesco

I see that the Console in your printenv shown is tty1, I doubt it to be tty0. If you are using either a USB2Serial/DB-9 Connector.

Check it out.
