With the Orange Pi Zero 2 (Bullseye), when in Armbian-config I install desktop with browser...it seems working but when you enable the desktop it finished by a kill() in the terminal. You can solve the issue by apt-get install tightdm.after and not before. You will get the desktop for the user and not root. Grey Background with the pinguin. If you install Desktop in Bullseye with Orange Pi One Plus or Orange Pi Zero, no issue. You have the new Debian Desktop with a Background dark blue. Regards F1ATB.fr

After flashing the last release (21.02.3) of Buster for Orange Pi One Plus H6 I discovered that no sound card was available. aplay - l gave: Then flashing a one year old version (20.02.1) the hdmi audio was available. But after making the updates, apt-get update , apt-get upgrade and enabling the Desktop aplay -l gives : no soundcard found. Please Help Regards https://www.fiatb.fr

Most of theses relays are designed to work with 5v power supply and thus have an input theshold between 0 and 1 somewhere in the middle voltage (2 - 3v). As a GPIO pin of an orange pi works between 0 and 3.3v. Sometime the switching to 1 does"nt wok as the input level is not high enough. Powering the relay with 3.3v allows to solve the issue as the input threshold moves down around 1.5v. The drawback is that the mechanical energy to swith the rely is lower and the electrical contact could be affected. Some of these blue relays have 2 power inputs. The 5v to power the mechanical part and the 3.3v to power the optical isolator at the input. This is the best solution to correctly switch. If you need some info on the GPIO for the Orange Pi One plus , I wrote an article on the subject. https://f1atb.fr/index.php/2020/06/16/gpio-on-orange-pi-one-plus/ Regards Ham radio F1ATB André
