IMX6DL: Kernel panic while booting

[apostoloskechag]

We created a custom board and we are trying to load Android. We compiled the kernel and configured the device tree but we get the following error.

CPU: IMX6DL

SW Version: Android M6.0.1

Kernel Version: 3.14.52-g87622e0

Any ideas on what might cause this problem?

one can try to run linux, start with minimal configuration..

Hi apostoloskechagias

kernel panic may be caused by ddr errors, one can run ddr test

i.MX6/7 DDR Stress Test Tool V2.80 

and rebuild image with new calibration coefficients found from test, replace them in

uboot/..mx6sabresd/mx6dlsabresd.cfg

Best regards
igor

Note: Array result[] holds the DRAM test result of each byte.
0: test pass. 1: test fail
4 bits respresent the result of 1 byte.
result 00000001:byte 0 fail.
result 00000011:byte 0, 1 fail.

Starting Read calibration...

We get this while running the calibration tool. Is this related to the problem? The calibration finishes successfully though.
