Hi
I'm trying to get the SPI ports to work in a RockPi 4B board.
I've done the following:
Installed the Armbian_20.11.6_Rockpi-4b_focal_legacy_4.4.213.img.xz image
Edited
armbianEnv.txt
overlays=spi-spidev
param_spidev_spi_bus=0
There is a entry at: /sys/class/spidev/spidev0.0, but nothing at /dev/spidev/
Next, I built libmraa, which fails to run any examples with SPI, as it can initialize any SPI devices.
What am I missing, Hope you can help me
