Hi everybody, I'm trying to use the SPI interface on my new Beaglebone Green. I was used to use the SPIDEV1 on my former BBB just loading the BB-SPIDEV1 DTO, but with this new board this DTO conflicts with the "univ-emmc" one. Below my Linux version and errors I get when loading the SPIDEV1 DTO file. The same problem with the PWM controller. I'm wondering how to to use the pins P9.31 and P9.22 allocated by the univ-emmc DTO. Having a look to the univ-emmc.dts file I've discovered P9.31 pin is allocated for "audio". I really don't know what does it mean... Could you help me please? Thank you in advance.
