Compiler: How to communicate between MCU1_0 to MCU2_0 using IPC

Tool/software: TI C/C++ Compiler

Hi, i want to use IPC communicate between MCU1_0 to MCU2_0, I used

status = appRemoteServiceRun(
        APP_IPC_CPU_MCU2_0 ,
        REMOTE_SERVICE_NAME,
        CMD_START,
        (void*)g_cmdPrm,
        CMD_PARAM_SIZE,
        0）

i think appRemoteServiceRun() is the target core receiving service commands, but about the current core appRemoteServiceRegister() requesting to send services, I did not find any specific details.

I wannt to know about details about sending service and receiving service,could you provide a demo about cmmunicating corectely?

Hi Lu Zhiang,

I assume you are using TDA4 EVM with SDK7.1. Please correct me if you are using a different HW and SDK.

Here is the IPC user guide capturing details on IPC examples between MCU 1 0 and MCU 2 0 cores.

Thanks & Regards,

Sunita.
