We are developing on a TDA4 D3-RVP, and would like to implement a QT UI, I have seen a previous post where you did get this working. We have everything working on a TDA4VM-SK but when we try to setup the D3-RVP we are seeing [ 3773.540832] tidss 4a00000.dss: CRTC0 SYNC LOST: (irq 80) messages. the display looks like it is talking:

When I try to do the kmstest we do get an error
root@j7-evm:~# kmstest
Could not get DRM master permission. Card already in use?
I was wondering if you could point us in the correct direction for figuring out what we may be missing.
