TDA4VM: Magna Fisker: Missing data in IPC communication between MPU1_0 to MCU2_1

Part Number: TDA4VM

TDA4 SOC: we established simple RpMessage based IPC communication between MPU1_0 to MCU2_1. We have use case to send a packet of 20 bytes of data between cores at 30 msec rate periodically with unique sequence number . We are experience inconsistently in the data reception; sometime packets are missing.

 MPU1_0 is running in QNX RTOS and MCU2_1 is running TI RTOS.

    Hi Ponnusamy,

    Are you using the standard RPMessage IPC or did any custom IPC on top? What SDK version are you using?

    Also, what addresses are you using for IPC shared memory? Make sure these addresses are marked as non-cacheable in the R5 MPU.

    regards
