Falcounet Posted January 25, 2021 Posted January 25, 2021 (edited) Hello ! i'm trying to enable the SPI interface on a OrangePi4B board using Focal latest stable build, so I edit `/boot/armbianEnv.txt` to add these lines : overlays=spi-spidev param_spidev_spi_bus=0 But after rebooting, I'm unable to access to the board anymore (No IP address is assigned to the board by the DHCP server). What's wrong ? Is there any additionnal steps ? FYI, I also tried to enable SPI using armbian-config tool but it doesn't work neither. As this tool doesn't even specify the `param_spidev_spi_bus` parameters which is required according to the overlay README. Edited January 25, 2021 by Falcounet add build info
Solution thc013 Posted January 25, 2021 Solution Posted January 25, 2021 overlays=spi-spidev param_spidev_spi_bus=1 or overlays=spi-spidev spi-add-cs1 param_spidev_spi_bus=1 param_spidev_spi_cs=0 spidev is 1 installed wiringop ? 19 mosi 21 miso 22 ce (my configuration) (gpio pin 56 with wiringop) 23 clk 24 cs so for example my spidev setting in nrf24 radio = RF24(56, 10) and for exampe mysensors ./configure --spi-spidev-device=/dev/spidev1.0 --my-transport=rf24 --my-rf24-ce-pin=56 --my-rf24-cs-pin=42 --my-rf24-irq-pin=55 but there indeed a error in the dmesg for spi in 5.10.10 but it works tested with a nrf24 module
