latze Posted May 6, 2018 Share Posted May 6, 2018 (edited) Hi @all, I currently try to build a door-opener with a NanoPi Neo and a MFRC522 Rfid-Module. Unfortunately I don't get the SPI working. I loaded the newest Armbian-Debian from the Website: uname -r = 4.14.18-sunxi and downloaded the SPI-library for NanoPi: https://github.com/wertyzp/WiringNP By using armbian-config I activated "pwm", "sei-add-cs1", "spi-jedec-nor" and "spi-spidev". The problem: If I try to activate SPI with gpio load spi I get the following error-message: modprobe: FATAL: Module spi-sun7i not found in directory /lib/modules/4.14.18-sunxi gpio: Unable to load spi-sun7i So it seems that wiringNp doesn't use "spi-dev" but "spi-sun7i" and I tried to install it from source from: https://github.com/OLIMEX/OLINUXINO/blob/master/SOFTWARE/A20/A20-build-3.4.90/spi-sun7i.c Unfortunately I can't find out how to write the Makefile so that I can compile the .ko-file and install the driver. Can you help me writing the Makefile or have another idea how I could solve the problem? Thanks in advance and greetings, Latze Edited May 6, 2018 by latze Link to comment Share on other sites More sharing options...

Thanks in advance and greetings, Latze Pay attention to the theme I created, I got it and there I brought libraries that used. https://forum.armbian.com/topic/7635-rfid-mfrc522-on-nanopi-neo/ Link to comment Share on other sites More sharing options...
