Network driver panic on TWR-LS1021A - Qoriq SDK-v2.0

skrishnakar · ‎06-01-2016

Hello All,

I have been trying to boot the LS1021A-TWR board with Qoriq SDK v2.0 and been seeing this network driver crash there after the NFS boot hangs:

Could anyone confirm that network driver is working without any issues in Qoriq SDK v2.0 for Layerscape LS1021A board ?

Thanks in Advance!

All images of u-boot, rcw and kernel 4.1.8-rt8 are booting fine and network driver is also working fine on TWR-LS1021A-PB Rev 2.0.

bump.

this is quite a serious issue. could someone please look into this?

thanks!

ufedor · ‎06-20-2016

Please provide corresponding U-Boot log.

xkonni · ‎06-20-2016

sure, just created a fresh one (rootfs, uimage, dtb directly from sdk2.0).

thanks for your help!

ufedor · ‎06-23-2016

Were you using SDK 2.0 pre-built images?

If "not" - what were the kernel build options?

xkonni · ‎06-23-2016

Yes this log was with the pre-built sdk uImage, dtb, rootfs.

But custom images with a slightly modified ls1021a_defconfig, yocto sdk2 branch lead to the same issue.

ufedor · ‎06-28-2016

Please check the board switch settings - what are they?

xkonni · ‎06-29-2016

SW2[1:8] = 0010 1111

SW3[1:8] = 0110 0001

like described in the demo pdf.

but apparently the issue was that I didnt flash the new u-boot to the sdcard. issue seems resolved.

ufedor · ‎06-01-2016

Please provide U-Boot log for the board.
