aen-rpc-pingpong

OpenAMP RPMsg ping/pong between the two E8 M55 cores via Zephyr ipc_service over the ARM MHUv2 mailbox + a shared-SRAM0 vring. RESULT PASS — pongs = 16/16.

Source: examples/aen/aen-rpc-pingpong/.

What it does​

  1. HP boots HE, then both endpoints bind over alif,mhuv2-mbox (the SDK's own MBOX driver, distinct compatible to stay collision-free against the vendor fork's arm,mhuv2).
  2. HP sends 16 pings; HE pongs each back; the count is verified.

The sibling aen-alp-rpc wraps the same transport behind the portable <alp/rpc.h> framed-RPC surface (16/16 PASS). With the AEN mailbox controller wired (mailbox.controller = alif_mhuv2, was TBD), alp_rpc_open is unblocked on AEN801.
