Re: Introducing Pi386

That's what I wrote above regarding /lib/modules. This package is not usable until that is addressed.

The only way neoaikon was able to get it to run was that his existing system had a 3G/1G split.

Re: Library to develop 2D game?

WillBoxOwO, The Hello SFML example runs at less than 15% (of a single core) at full screen on my Pi 3B+. It's only when I run with the legacy driver does it have a 350% CPU usage problem. Based on your other posts, I suspect your problems with 2D engines could be related to the same issues you initi...

Re: Arm A53 AArch64 Support

64 bit kernel under a 32 bit raspbian is working fine for me, and I'm in the process of fixing up the bits of the kernel that don't work. All the Mmal and IL apps I've tried still work with that, as the buffers passed from the 32bit app still map correctly onto the Gpu versions of those structures....

That's too bad Berryboot is in the way. If you're running the legacy driver this not only hinders testing GL/GLUT/GLFW applications, but you can't write standard GLES either.
