We're migrating PRU code from the AM335x processor to the AM6548 and noticed that the Mailbox 0 constant table entry (22) was removed in the AM6548 so it is no longer available in the PRU/RTU local memory space.
We are looking for a simple, thread-safe means of passing data between the ARM A53 cores and the ICSSG PRU/RTU cores.
Internet searches have revealed only examples for the AM335 (BeagleBone black).
Thanks in advance!
