After successfully building and loading the example found in the “pru-software-support-package-6.2.0” “examples/j721e/PRU_RPMsg-Echo_Interrupt1” I don’t get the device path that I expected “/dev/rpmsg-pru31”. The example for “PRU_RPMSg_Echo_Interrupt0” functions correctly giving the device path as “/dev/rpmsg-pru30”.

The same examples work correctly for the Beaglebone Black using Bullseye.
