AM625: MCU-A53 IPC memory

Hello Akshay,

Keep in mind that there are many different kinds of IPC. The examples we provide between Linux A53 and an MCU+ core are:

1) RPMsg (496 bytes of information passed at a time), which requires VIRTIO buffers to be defined in DDR memory, and

2) a shared memory example where each core directly reads and writes to a larger area of memory. This user-defined shared memory could be placed in DDR, or on-chip SRAM. You can find the zerocopy example here.

I'll link to some helpful AM62x Academy pages that might help you get started here:
