>I think you only need spidev turned on in armbian-config
This is what I did first, but could not find any ( in the /dev ) spi device. This triggered my to start searching for a solution and as far as I understand from this thread, there is a misconfiguration in the standard image. This is from the armbian website of the orange pi zero 3:
Do you expect that in an image with an build Date of Jan 16, 2025 these fixes to get SPI to work are included?
>I don't know why you copied a dtbo to /usr/lib/linux-image...
Because I have very very basic understanding of the device tree. My thinking was, I do a
sudo find -name *.dtbo -printf "%c %p\n"
And see where the original files are ( that need to be changed). As I did not know what file are used during boot, I changed them both of them. I am still not really sure if you can replace these files on the sdcard and expect that they are used during boot. Is my expectation correct that I can just replace them on the sdcard and reboot, or do I need to rebuild and kernel/image ?
What shows up in ls /dev/spi* ?
/$ sudo ls /dev/spi*
ls: cannot access '/dev/spi*': No such file or directory
adif did get it to work and you can see that pin 24 if configured different.
