Kernel Panic error

Hi,

I am facing a kernel panic error when booting iMX25 PDK with SD Card. Need help to resolve this error. Screen shot is attached

Thanks,

Could you share the full kernel log before the kernel panic?

It seems you have a bad rootfs flashed into the SD card. For a quick test, you can try to booting via NFS.

It's preferred to use ext3 instead of ext2.

Try the command line below as per mx25 Linux BSP User guide document:

noinitrd console=ttymxc0 root=/dev/mmcblk0p1 rootfstype=ext3 rw ip=dhcp

I have exactly the same problem, very frustrating. I need to establish a working toolchain, or abandon this and find something that works.

I installed the Linux VM on a Windows system. BTE: The system REALLY should ship with an errata sheet -- just getting thru the apt updates was annoying. But set that aside.

I ran the config, set in a few options, did a build, and made an SD card. Kernel panic.

Examine the config about 12 times, same thing.

Okay, maybe I did something horribly wrong. Build a pristine VM, run configure and accept the defaults. Build a new image, copy to SD card.

Same crap. Boot file is attached.

Any ideas where to go from here ? Or should I give up ?

fabio_estevam — Sat, 02 Mar 2013 21:29:29 GMT

I looked at your log, and it does seem to be a different issue as the one reported in this thread.

Your log does not show your complete kernel command line, but you are passing "gpmi" and trying to boot from SD card.

This is not correct as per the mx28evk Linux BSP User Guide document. You should pass "ssp1" instead.

Other than that, you are using a 2.6.31 kernel on mx28evk and I would strongly recommend to upgrade this kernel and the options are:

- 2.6.35 kernel from FSL + LTIB root file system

- 3.8 kernel from kernel.org + Yocto root file system

Both options work well.

By the way, Yocto generates an image that you can simply do a 'dd' into your SD card and you have a bootable system.
