PROCESSOR-SDK-AM335X: PRU Ethernet on Beaglebone Black

Goodmorning,

I have a Beaglebone Black and I'd like to use PRU for controlling the Ethernt Port since I need Real Time Ethernet.

I've read this link and checked that on kernel tisdk_am335x-evm_defconfig they are enabled as default.

Now, as per my understanding, I should change the device tree so that it configures the pins for pru and calls the driver.

I ask you two things:

  1. Is it possible to configure one of the pru (pru1 or pru2) to drive the ethernet port?
  2. In case the first question is affermative, where can I find a dts as starting point? I found someone that did it with AM335x-ICE board (), but I cannot find an official TI dts.

Thank you.

Best Regards,

Davide Brunelli
