Random kernel crashes observed on some boards

custom_board

#1

Hi,

We are using latest OpenEmbedded Release based on 4.11 linux kernel on snapdragon820 based custom board.
Release: http://snapshots.linaro.org/96boards/dragonboard820c/linaro/openembedded/rocko/latest/rpb
Manifest URL: https://github.com/96boards/oe-rpb-manifest.git
Manifest branch: qcom/rocko
Linux Kernel Branch : release/db820c/qcomlt-4.11

On few boards, we are observing random crashes(Crash log differ on every boot) after resizing the rootfs and where as some boards are working fine.

We doubted that it could be DDR problem so we have done ram test from xbl on both working and not working board and it is passing on both the board.

I know this seems weird but we are clueless where to debug. Do you have any idea where we should look ?

P.S : Android is working fine on all boards.

Below is one of the random crashes.

#2

There is not yet releases for the 820C but snaphots. 4.11 is no more maintained and I strongly suggest you to move on 4.14 (release/qcomlt-4.14) which should be much more stable. (btw latest snapshot is based on Linux 4.14).


#3

Hi

We need eMMC boot support which is broken on 4.14 and that is one reason we didn’t move on to 4.14

Thanks,
Pankaj


#4

To be honest you should probably invest some time investigating and fixing these boot problems. Until these are fixed you are pretty much cut off from all future 820E kernel development.

PS Make sure your bootloaders are properly updated too: 4.14 doesn't boot on ifc6601


#5

Thank you for your suggestion !

What are other major features that we can expect in future. @danielt @ndec


#6

you can expect everything :wink:

GPS, video codecs, analog and digital audio, MIPI camera, … these are all topics are we are looking at that should land sometimes this year in our 4.14 branch. Note that our main focus is upstream work for various SoC (not just 410 and 820, but a few others) and once things land upstream we add them into the release branch. The number of SoC we are working on has grown, that’s why 410 and 820 improvements are ‘slower’.

cheers
