[Cubietruck freeze after 1-3 days with 5.23 Xenial (uboot problem?)]

ok - here is my feedback, unfortunately uboot 5.24 does not fix it for me.

 

Cubietruck, Jessie Legacy kernel (3.4.112-sun7i) Image 5.20 with all updates. Stability tests witch cpufreq-ljt-stress-test and Lima Memtester.

 

uboot 5.23: Kernel crashes after few seconds during load, Error on console:

Unable to handlE kernel NULL pointer dereference at virtual address 000000

uboot 5.24 beta (linux-u-boot-cubietruck_5.24.161109_armhf.deb): Kernel crashes after few seconds during load, Error on console:

Unable to handle kernel paging request at virtual address xxxxxx

Downgrading uboot to 5.17 or 5.20 - everything is rock solid. No problems during complete runs of cpufreq-ljt-stress-test and Lima Memtester.

I think I see similar problems with uboot 5.23 on my cubietruck. Going back to uboot 5.17 fixed it for me for the moment.

 

See my post here: https://forum.armbian.com/index.php/topic/2044-some-discovery-while-trying-520-builds/

 

I'm going to test the beta version, too.

 

Thx

[Some discovery while trying 5.20 builds]

Martin, folks,

 

I can confirm the

Unable to handlE kernel NULL pointer dereference at virtual address 000000

errors after a clean install from scratch of the current jessie 5.20 images (both vanilla or legacy) and updating all packages (apt-get upgrade) on my cubietruck.

 

Sometimes I saw crashes during boot but mostly with some load. Lima memtester and cpufreq-ljt-stress-test both crash the cubie after few seconds.

 

Downgrading uboot from 5.23 to 5.17 ( linux-u-boot-cubietruck_5.17_armhf.deb ) fixes this problem.

 

With uboot 5.17 both Lima memtester and cpufreq-ljt-stress-test run without any errors or crahes.

 

Any chance, this can be fixed? For the moment, I put the uboot package on hold for apt-get upgrade.

 

Thx

Tobias
