AM335x PRU SPI Communication

Hey there,


I want to talk with the PRU to an SPI Device, but I did not see how I can enable the sclk or pull down the Chip Select.

I have a BeagleBone and I already read the SPI device with IOCTL commands and it works but the performance is really low... So I want to put the data collecting to the PRU, but in the last 2 Weeks I dont find how to do this. There are so many registers but I dont know which of it


Can you help me?
