I'm running Armbian 5.65 and only interested in SPI0.
Following willmore:
1. Installed the new boot.cmd and ran mkimage (Same result, broke my kernel)
2. Tried sun8i-h3-spi-spidev.dtbo file from martinayotte (Files on my board was: sun50i... which seemed strange)
3. edited /boot/armbianEnv.txt to add:
overlay_prefix=sun8i-h3
overlays=spi-spidev
param_spidev_spi_bus=0
param_spidev_spi_cs=0
param_spidev_max_freq=100000000
(I also remembered changing SPI0 from disabled to okay, but going back in the files I do not see it anymore. Think it was part of a longsleep ubuntu I tried before.)
4. add overlay_prefix=sun8i-h3
5. Tried hard not to be stupid(failing miserably)....
Rebooted in between a couple of times, however nothing in /dev. After looking at jbird1 I'm seriously confused. No solution seems to work out of the box.
This thread jumps around a lot, is there a step by step I can try and follow?
