  1. Orange Pi Zero 2 UART connection

    Nacho Blanco posted a topic in Beginners
    Hello I'm new in Armbian. I'm trying to connect one Orange Pi Zero 2 to a 3d printer (board Cheetah v1.2) using UART in order to install Klipper to control the printer. I can't find how to enable the UART port to connect. I'm planning use UART 5 (pins PH2 PH3 according to this pinout http://www.orangepi.org/orangepiwiki/images/e/e3/Orange-pi-zero2-img4.png) . I've been searching for hours the right way to enable the UART communication, but I've not found a clear explanation about how to do it. I've trying armbian-config but Hardware option doesn't appears in the Menu. I'm using the Armbian_22.11.3_Orangepizero2_bullseye_legacy_4.9.318 image. Also, I've another question: I dont' know why but most of the images from the repository doesn't boot. The red ligth on the board never changes to green and of course i can't connect to the Opi. Why could be the reason? Thanks
