Could we have a direct link for:

Raspbery Pi Zero W OS: Raspbian (Linux raspberrypi 5.4.79+ #1373)

kernel 5.10 has issues with the showfb example. Testing on Pi Zero W.

Hi, The Raspbian I used seems to be released on 2020-12-02, but now I couldn't find a link. I will try to fix the problem with kernel 5.10 or newer version.

ryomuk commented 2 years ago

It was a know issue. See https://github.com/ryomuk/gu3000/issues/1 To fix: in /boot/config.txt: framebuffer_depth=16

I will update a document soon.

Yes that was the fix I had to add and if using the 2020-12-02 release minimal, Overlay needs to be enabled in raspi-config.
