Hi, i stopped working with BBB. I am a "normal" freak and need more support. I am no professional it-expert. So i am back to raspberry pi, much more boards and support and tutorials in the web.
If you allready have some SPI dts files in /lib/firmware then try to load it by using the echo: echo BB-SPI0-01 > /sys/devices/bone_capemgr.*/slots if you want to use SPI1 then you have to disable the HDMI. But i never get the SPI running as i want. Am Samstag, 26.
