I got an initial accelerated desktop
going on RPI3: I had no luck with the open source driver (vc4-kms-v3d), I have to use a HDMI=>VGA converter, somewhere the EDID gets lost
, and I was unable to set it manually, I only get a black screen, despite discussions with the developer Eric Anholt: https://github.com/anholt/linux/issues/56
But now Eric added a way to use the closed source driver:
In short: instead of using
in the /boot/config.txt
This gives me ~230fps with "vblank_mode=0 glxgears". I now have OpenGL active in OpenCPN and the BR24 radar
plugin started working.
OpenCPN currently freezes when activating a second radar
window (B&G 4G) but this is a separate topic. Very happy with the progress!
Edit: Raspian, fully updated, and kernel (firmware) updated to latest as of writing. uname -r: 4.4.23-v7+ (not yet ready to compile my own 4.8 kernel...)
