Great! See https://wiki.radxa.com/Rockpi4/dev/serial-console for a guide on how to connect the serial lines to the board and setting up a terminal program. The wire colours are different, but take a look at the picture on that link: Do not connect the +5V or 3V3 pins GND cable needs to be connected to the 3rd GPIO-pin (GND) on the top/outer side of the connector (the black wire in the picture) RX cable needs to be connected to TX, that's the 4th GPIO-pin, just below the GND wire (it's white in the picture) TX cable needs to be connected to RX, that's the 5th GPIO-pin, just below the RX wire (it's green in the picture) (If you can't connect, then RX and TX needs to be swapped. Don't worry, having these lines swapped won't break anything, it just doesn't allow a connection when wrong.) Then start the terminal program (e.g. putty on Windows or minicom on Linux, both described in that link). When booting the RockPi, you should see the boot messages in the terminal window (otherwise try swapping RX/TX). Keeping the spacebar pressed (in the terminal program, make sure it is selected) should then interrupt the bootloop and you should be able to copy&paste the output. If interrupting still does not work: Putty has the opption to copy the whole content to clipboard: Right-click the title bar and select "Copy All to Clipboard". Then paste it into an editor. Once you have pasted that log into an editor, you can try to clean it up a little bit, it may contain several boot attempts. It would be sufficient to include just one complete boot attempt and the start of the next. But if in doubt, use the complete log. Finally post that log here.

Whoops forgot to add that, there are no pwm related overlays on armbian install.

Check if there are pwm overlays available in /boot/dtb/allwinner/overlay. If so try enable via armbian-config or manually with overlays= in /boot/armbianEnv.txt

I thought it was Arm7, and remember it can only run 32 bit stuff.

Hello! PWM seems to work without any configuration on the factory images with the gpio command, but I cant seem to get it to work on armbian. There doesn't seem to be any dtbs related to pwm, and /sys/class/pwm is empty on armbian. Anyone got this to work? EDIT: Forgot to add, doesnt seem to be any pwm overlays present on armbian install
