Thanks Robert.
All that stuff hasn’t been re-ported to v5.10.x yet…
Noted. Facing problems and digging to try to solve them is an excellent way to learn. I’ll report issues on github (link mentioned at the top of your post), where I should have done so from the beginning (instead of here).
Feel free to use the TIDL specific 10.x (buster) Snapshots: Debian 10.x (Buster) - Monthly Snapshots
Will do, in order to get familiar with the PRU; but since a lot seems to have changed in the Bullseye release, I’d also like to jump in to the Bullseye train early.
Best, Ludovic
