I am trying to enable SPI3M1C0 with following pins on my Rock 3A
GPIO4_C2 (CLK), GPIO4_C3 (MOSI), GPIO4_C5 (MISO), and GPIO4_C6 (CS0).
But no success. I am out of idea, try different overlays but still not able to enable them.
I used this overlay
I expect to see “/dev/spidev3.0” but nothing appeared.
here is my armbianEnv.txt content:
“”"
cat /boot/armbianEnv.txt
verbosity=7
extraargs=cma=256M bootargs=debug
bootlogo=false
console=both
