Hi all, SPI has been enabled into /boot/armbianEnv.txt with: overlays=spi-spidev param_spidev_spi_bus=0 Nothing works knowing that the wiring between device and BPI has been checked more than 3 time. How can I check that SPI0 works well? where can I check that dtd file is correctly loaded? What are created files on fs when the spi port is correctly enabled? ==> Armbian 21.05.1 Focal with Linux 5.15.48-sunxi Many thanks
