im trying to connect nRF24l01 module using this code
I successfully enabled SPI1 on BBB, spidev device appears in the dev, if I
connect d0 and d1 pins and run spidev_test it transfers data successfully.
However when I connect my SPI device I only get zeros back.
I switched MISO and MOSI pins just to be sure I didnt make mistakes there,
but still it didnt help.
to work on spi1 you also have to disable hdmi.. you can see how to do it here:
