I can’t activate SpiDev with debian version 21.12 on the dragonboard 410c. I followed the whole procedure described here:
I checked in the configuration file and found:
The procedure goes smoothly but after restarting SpiDev is not present in /dev. I also tried doing modprobe spidev, without success.
I then returned to version 21.03 and the enabling of SpiDev works perfectly with the same procedure.
Thanks in Advance.
