Project not working on raspberry pi 4

[floion]

The rpi4 firmware support for the bcm closed source opengl drivers has been discontinued and now only using the kms driver is supported on pi4 (by using the vc4-kms-v3d overlay).
This means this wpe project needs to be recompiled against the open source gl libs. So the backend will probably need to change to fdo here: https://github.com/balena-io-projects/balena-wpe/blob/master/base-image/meta-resin-wpe/conf/samples/local.conf.sample#L35 and also https://github.com/balena-io-projects/balena-wpe/blob/master/base-image/meta-resin-wpe/conf/samples/local.conf.sample#L36 needs to be removed.
And for using the new base image compiled with the above changes, we will also need to figure out how to use weston to make it display nicely on the screen (from what I saw at a quick glance, the fdo backend uses weston)

If someone can link me to a 'getting started editing balena proejcts' i'm happy to try and create a patch for this.

@codefriar you would need to do the changes highlighted above, then recompile the base image using the build script https://github.com/balena-io-projects/balena-wpe/blob/master/base-image/build.sh , then push the resulting image to dockerhub, then change wpe to use your newly built image (change would go here https://github.com/balena-io-projects/balena-wpe/blob/master/Dockerfile#L1 ) .
Then commit these changes and then git push balena.
So at this point you would have wpe running with weston and from here you would need to figure out how to get it to render on the screen.

Hello,

Is there a plan to upgrade for Pi 4?

Thank you

[floion]

@liquidmagic we need to put this issue in the prio list somehow; not sure when that will happen

We'll make sure to update this ticket with the progress

This was my one use-case for Balena, and I went and bought a Pi 4 without checking this. Woops. Looks like I'll scratch the Balena plan, oh well.

Hi,
I build the Image with the changes descried here for VC4 support: https://github.com/Igalia/meta-webkit/wiki/RPi
The Image can be found here: https://hub.docker.com/r/danielboe/resin-wpe/

Here are the changes I made:
https://bitbucket.org/danielboe/balena-wpe/commits/8d73c841fc55df0b2c77a3fe4495cebf4888f33c

I stuck now with the Error:

Edit:
After changing cog to this I get new error messages:

@jbotte @vbersier @lukecurtis93 They have another repo with a gpu accelerated chromium browser that supports RPI4

@niedfelj looks promising! For now I'm using the balenaDash project since it has a chromium browser that works on rpi4 as well. But the link you provided looks more in line with what I need.
