Hi Jadon,
Could you help me ?
Do you have a example with ARM.c and PRU.c source code that show a DDR memory accessed by the PRU on BeagleBone Black?
Thanks so much!

The above support package is a starting point. Look in the examples directory.
These are remoteproc based, however, it is all C code so you will definitely learn some C programming of the PRU by studying these examples.
Regards,
Greg
