Hi,
I’m trying to upgrade from:

Torizon OS:6.4.0
torizon/weston-vivante:2.8
torizon/chromium@sha256:9d363b140a5f4584392432b4ed548c0b6fd5466fbf41b28e834f31924fb62d6d 

// sorry for the sha of chromium but I am not able to retrieve the version from your docker hub

TO:

Torizon OS:6.5.0
torizon/weston-vivante:3
torizon/chromium:3.1 

 //I try  weston-vivante:3.3 too

But Weston simply does not start, here the docker-compose file:
docker-compose.yml (1.3 KB)

Log:

Hello @vix,

Thanks for the detailed explanation.

From weston-vivante:2 to weston-vivante:3 there were a few changes to the weston container.
For this reason, you need to give it more access to tty devices. This requires a change in the device_cgroup_rules property of the weston container:

    ...
    device_cgroup_rules:
      - c 4:* rmw
      - c 13:* rmw
      - c 199:* rmw
      - c 226:* rmw
    ...

If you run your docker-compose with just the above change, a WebGL error will likely appear. This error is caused by a regression on torizon/chromium:3.1.

Edit: The regression has been fixed, to use the updated image, you can use the torizon/chromium:3.2 container.

Best Regards,
Bruno

@vix
try to change the gpu in the settings.json to “-imx8” instead of “-vivante”.
I have here the same Problem https://community.toradex.com/t/every-start-of-vs-code-the-settings-json-will-get-wrong-gpu-value/21949/2

best regards

Hello @tf_hosenso.de,

The “-imx8” containers are still in a release candidate or “rc” state.
The “rc” containers are in constant development and are not explicitly versioned. This makes builds or tests based solely on the “rc” tags unreproducible. This can lead to instabilities and compatibility issues.

For these reasons, it would not be advisable to use “rc” containers unless you are looking to test a fix to a known issue. Even in those cases, downgrading to a known working version when possible would be preferred.

Best Regards,
Bruno
