I don't remember exactly the status for the kernel but for graphical uboot, the patches are not (yet) upstream. I hope to send patches for review soon. Meanwhile: - the patches are at: http://people.hupstream.com/~rtp/pbp/20200727/ - binaries can be found here: https://github.com/samueldr/wip-pinebook-pro/pull/13. Unfortunately, due to commit "pwm: Read initial hardware state at request time" in linux kernel, using uboot with my graphic patches will freeze the kernel (this means 5.6+). The issue is not fully debugged atm but you'll find a patch in Samuel's PR to workaround the issue. > > > I have had luck pulling the patches from one of the manjaro 5.8 > branches: > > https://gitlab.manjaro.org/tsys/linux-pinebook-pro > > Applying those patches to a mainline kernel, which should work on > Debian's kernel without too much trouble(beyond learning quirks of the > linux packaging in Debian and the effort to actually build the > package).

It's more or less on my TODO too, but I prefer working on upstreaming my uboot patches first. Arnaud
