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

FrancescoNamuri — Fri, 04 Nov 2011 06:26:13 GMT

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.
