Hi,PrabhanjanKopp
Thank you for contacting us.
1.Before sending, the function ipc_shm_is_remote_ready() should be called to confirm that the remote end is ready.
2.It is necessary to refer to the S32Z2 manual to confirm the respective MRU instance and channel for core 0 and core 1 of the RTU0.
Could you tell me the version of S32DS/RTD/IPCF you are using? If possible, could you send your IPCF project to me? It is better help to check it and handle this issue.
