Hi, all.
I've been poking around on PI3B lately (14.0 armv7)
Couldn't get graphics-KERNEL working, the screen always goes black when loaded.
Can reboot with the keyboard just fine, so I know the system doesn't freeze.
If I comment out dtoverlay=vc4-kms-v3d, then load the extension, nothing will happen.
Although I can probably do that and start compiling stuff, I'd rather not.
I've tried both older and newer rpi-vc.tcz from repo (14.0 armv7) and (14.0 armv7l)
Booting with base norestore
Replace graphics-armv7 with graphics-armv7l
None of them would keep the screen on once the graphics extension is loaded
Any suggestions ? I'm new to kernel modules debugging
