I am using BeagleBone enhanced and was configuring my two SPi's. I have disabled the hdmi feature to run both SPIs in paraller. However I can only run SPI in these configurations SPI(1,0) and SPI(2,0). I wanted to ask whether it means they are running independently of each other or are they both running on the same bus i.e., 0 and also why cannot I configure the SPIs in the configurations SPI(1,1) and SPI(2,1)?

I would be quite grateful if anyone could guide me through this. I have been looking all over the internet about this issue.
