BeagleBone black UART interrupt PRU

Monir Sabbagh

Hi,

Any steps or sample on how to write a program on BeagleBone Black (Angstrom linux) to use the UART with interrupt in PRU , I am connecting a ZigBee using serial communication. I started with PRUSS examples which are successfully runs.

Thank you for your help.

Monir,

I think a PRU UART example is still a gap on our side. I looked around the web a bit this morning and did not see anything in the community either.

As an FYI there is a softUART example on our wiki, but this is not built to run in Angstrom and obviously is software-based instead of using the hardware UART in the ICSS.

Thank you for your answer, your link for softUART is pointing to a missing group!

The steps of UART in "AM335x PRU-ICSS Reference Guide" is hard to follow (at least to me).

Sorry, I am not sure what happened with the link in my previous post. It was not supposed to be pointing to the E2E. I've updated it to the correct wiki page.
