CCS / IWR1642BOOST： IWR1642 mailbox mechanism operation

Part Number: IWR1642BOOST
Other Parts Discussed in Thread: IWR1642

Tool/software: Code Composer Studio

Hello, TI engineers. In IWR1642, how to use the operating system's mailbox mechanism to communicate between the DSP core and the ARM core? How to use the mailbox to send DSP data (such as an array of data) to the ARM core through the mailbox? Finally, it is printed on the ARM core through the serial port. Is there any relevant information or program routines? How should I operate specifically? Thank you

    Hi ZHG,

    Please look at the following resources:

    1. Mailbox driver test and provided doxygen documentation in SDK:
      1. Doxygen: C:\ti\mmwave_sdk_02_01_00_04\packages\ti\drivers\mailbox\docs\doxygen\html
      2. Driver test: C:\ti\mmwave_sdk_02_01_00_04\packages\ti\drivers\mailbox\test
    Mailbox usage in SDK OOB demo source code:
    1. Driver initialization in mss and dss main.c files
    2. MmwDemo_mboxWrite() function calls to send the message in mss and dss main.c files
    3. MmwDemo_mboxReadTask() function to receives the messages in mss and dss main.c

    Regards
