Same - Did not work for me on a Libre Renegade rk-3328-cc either.

Understood - It was not my intent to malign the community in any way. It was simply surprising to me since I thought SPI was widely used on most popular ARM SoCs. No worries, you all are much appreciated.

I guess Armbian is the wrong OS for the Renegade… I expected this to be relatively straight forward.

Looking for information on enabling 4 wire SPI on the Libre Renegade. I think have it enabled (spi-spidev) in armbian-config and I think configured correctly in /boot/armbianEnv.txt: param_spidev_spi_bus=0 param_spidev_spi_cs=0 param_spidev_max_freq=1000000 Connecting to pins GPIO pin# 19/21/23/24 I still do not see ANY devices matching /dev/spi* - An guidance as to WHY? I have the build framework, but am new to building armbian kernels but could navigate it with some direction. TIA folks!
