Hi everyone,
I recently just built flashed the r3 with a nand image, using the sources from this repo.
cat /lib/modules/5.4.99/modules.builtin | grep spi confirms the presence of the spidev module. However there isn’t any /dev/spi* file. Looking at the contents of the file board/widora/mangopi/r3/devicetree/linux/devicetree.dts I only find the device node for the first SPI controller (spi0) with child nodes spi-nor & spi-nand and none for the second SPI controller (spi1 ?). Do I need add another SPI device node to these file?? or is there something I’m missing??
Any help would be much appreciated
