Hi all
Well we've reached a point sadly where the rpi3 code is not going to work any more using Bullseye. all the old Broadcom vc4 drivers have been depricated and are no longer part of the bullseye install, so the code will no longer build or run as it stands.
Generally this isn't a massive issue, as once we have the graphic systems set up we can ignore the OS, but in the case of the Rp1-3 the broadcom DispmanX system was used to make the graphics framebuffers. Without them the code isn't going work
But in theory installing the mesa libs which now have VC4 support you can get things up and running, the set up is similar to how we do the Pi4 code, and we now use X11 to send our graphics to the screen.
But there's a small problem at the moment with the EGL drivers not initialising, I am looking into it, when I work it out, I'll post a new hello triangle project set up for you here to allow you to progress if you are using a Pi1-3
Im working on the issue and will try to get the fix to you soon, I've also asked the Pi forums if theres a way to install the depricated system.. I suspect not but who knows.
