Simple GPIO toggling has been a long term issue and it is clear to me that it need continued attention. I only use pin toggle on RPi1 and NanoPi-NEO, so BCM2735 and AllwinnerH3. I use generic Linux gpiod, still a bit a workaround for really proper handling, but it is OK for non-critical tasks at home. I used orignal WiringPi on RPi before (from Gordon), but many forks now. See also: https://forums.raspberrypi.com/viewtopic.php?t=369361 'latest' seems to be here: https://github.com/WiringPi/WiringPi?tab=readme-ov-file Note what is written under Ports w.r.t. Python. I guess Werner's guess is correct. I am not good at Python so prepared a bit for own C-code implementation, also w.r.t. high speed PWM. On AllwinnerH3 running Armbian Trixie, using the lgpio examples was easy to toggle a pin. I currently have Domoticz doing it, so also easy MQTT messaging, but it is overkill and also Domoticz build for ARMv6 is not available anymore (needed for RPi0/1), so already replaced that.

Thanks @eselarm for the details, very helpful! That's what i was expecting, but not sure. There is a /dev/media# device separated for each decoder and encoder, each with the source / proc / sink pipeline plus /dev/video# for each. Meanwhile i figured out there is a bug inside the sunxi_cedrus driver (enc by bootlin) but im still not done with the fix. As of now, since this morning i've now both video# devices where video0 appears as the decoder (as before) and now there is video2, encoder! T. btw. Thanks Paul @ bootlin 😃 👏 👍

Okay, I tested, but it works kind of weird: they work in tandem, but the boot messages were only output to the video console, not on the serial one. Once after the initial automatic login, the output started to go to both consoles, but the initial and systemd boot messages were only output to the video console, which would have made sharing the details of the initial problem difficult.

@c0rnelius Thanks for stepping in to help. I've added enable_uart=1 to config.txt In cmdline.txt, I currently have: console=serial0,115200 console=tty1 ... Do the two settings work in tandem, or do they override each other?
