Hi @patdex

Thanks for writing to the Toradex Community and sharing the issue.

What is your application? What is your use case for the SoM?
Did you restart the module during your tests or not?
How are you doing your tests? Could your share a sample code?

Best regards,
Jaski

hi @jaski.tx,

it is the same system as here:

only the crash looks different.

hi @patdex

Thanks for the Information, we will look into this issue and comde back to you.

Best regards,
Jaski

hi @jaski.tx

Are there any news to this topic?

hi @patdex

We are working on this. But there is no solution yet. If you want you could try to update to the kernel 5.2 or cherry pick the patches from kernel 5.2 and add them in 4.9.2.1 kernel.

By the way, did you try to use Bsp3.0 and check if this issue is also present in the newer kernel.

Best regards,
Jaski

hi @jaski.tx,

are there any recipes for kernel 5.2 and imx6ull?

Unfortunately not for regular Linux Bsp but kernel 5.3 is used for our Software Platform called Torizon. This can be built following the instructions on this site.

Best regards,
Jaski

Hi,
I am facing the same issue. Is there any progress on this problem?

Hi @qojote

We suggest you to use kernel 5.3.7. Please have a look here.

Best regards,
Jaski

Hi, I am using the BSP2.8 which is marked as LTS according to your website. One major feature of the iMX6ULL (the only reason why i chose this module) is the wifi part. Now there are already some units in the field and customers are complaining about that issue. How can i integrate the new kernel into the standard image build process via OpenEmbedded? Its no practical solution to change the whole SW infrastructure (Torizon, Docker, and last but not least our custom update mechanism).

First of all, for iMX6ULL, there will be future stable versions, which will become then LTS version.

Currently we know about this issue in Bsp 2.8b6 and we are working on this. A solution for the moment is to use the kernel 5.3.7 with Bsp 3.x, which works fine.

How can i integrate the new kernel into the standard image build process via OpenEmbedded? Its no practical solution to change the whole SW infrastructure (Torizon, Docker, and last but not least our custom update mechanism).

You build your image with Bsp 3.0 and replace the kernel and devicetree.

Jaski
