PRU UART

I am currently using PRU1 to sample data from an ADC chip and write the data to a file on the Beaglebone Black. Instead, I would like to send the data in real time back to a computer, presumably over a serial connection. It seems that the PRU has access to a UART but I’m having difficulty finding sample code that drives the UART from the PRU. Does anyone have any suggestions?

Thanks,

That uart is no different than any other of the TI Uarts that have plenty of examples. I know you can do it we did it at work because we used up all the peripherals and needed another uart, but this was completed before I arrived I remember wondering why anybody would go this route for us the DSP and ARM peripherals were all used up.
