I’m having problems setting up SPI0 on BeagleBone Green Wireless.
I’ve tried enabling it via pure dtb and via an overlay, be it custom one or BB-SPIDEV0-00A0, in almost every combination.
No matter what the configuration is, I can’t get a clock signal (I have an oscilloscope connected to SCLK pin - only some low-level noise) nor proper TX/RX (shorting MISO and MOSI results in reading garbage).
For testing I’m using spidev_test.

I’m using Debian with kernel 4.4.80-ti-rt-r116 (I’ve tried on 4.4.68 too).
