2010-03-22 10:16:09     Kernel Panic when booting uClinux

Cedric Marin (FRANCE)

Message: 87565   

Hi all,

I'm working with a TCM-BF537 module plugged on an EVAL-BF5xx card from Bluetechnix. I flashed U-Boot on the BF537 module (the TCM-BF537's u-boot.bin downloaded on   blackfin.uclinux.org/gf/project/bluetechnix/frs/). I then downloaded the TCM-BF537's uImage of uClinux 2009-R1.1-RC4 on the same site.

When I turn on the EVAL card, U-boot 2009 starts. I then load the uClinux image in the RAM (with tftp) and boot on 0x1000000. The system starts and fails with a kernel panic after creating the partitions. The booting logs are the following:

bfin> bootm

Message: 87566    Does you development board / module feature an NET2272 USB Device Controller?

Is it properly connected and are all the switches properly setup?

If you don't use the net2272 driver disable it in your kernel config and rebuild your kernel image.

Thanks a lot Michael,

it works !

The NET2272 USB driver was activated in the kernel and desactivated in hardware...
