Hello, today I received MCIMX6Q-SDP board, rev C3 and when I boot android 13.4 that works fine on revB board, I get the following error in the serial console:
!!!!!!!!!!!!! AXI BUS ERROR !!!!!!!!!!!!!
Serial console is responsive but Android fails to boot. Sometimes I don't get this error but Android hangs with kernel panic.
I attached complete log for the case when I get axi bus error.
Has anybody seen this issue before?

Solved! Go to Solution.
I was not correct in my description of the problem so let me do it again.
I have 700-27392 rev A of the MCIMX6Q-SDP board. I run Android (R13.4.1 BSP) and it's fine. However, when I try exactly the same software on 700-27392 rev B board it fails with
Note that pre-built image that came on the SD card with revB board works fine.
Do you have some kind of document that lists differences between rev A and rev B boards. I understand that this patch is needed and why it's needed but I'm confused why I see the problem on rev B board and not on rev A if there are no differences in the areas addressed by this patch.
Please check the schematic revision, "SCH-27392 rev.Cx". If the schematic revision is the sample, there should be no difference in PCB.
700-XXXXX difference could be some assembling or label changing.
I tried 13.4.1.04 pre-built u-boot.img and boot.img + 13.4.1 prebuilt system.img and it doesn't hang. I'll try with Android built with 04 patch applied and will report the result. Apparently, revA board doesn't require this patch while revB does.
