AM62A7-Q1: How can I implement the IPC in customer system?

Part Number: AM62A7-Q1

Hi Expert,

customer is using the ipc_rpmsg_echo_linux file locate in the mcu_plus_sdk_am62ax_09_00_00_19\examples\drivers\ipc, the log as below:

This program is entered by the ipc_rpmsg_echo_main function, executes ipc_rpmsg_create_recv_tasks to create message receive tasks, and then jumps to ipc_recv_task_main after printing out
Two sentences of log, judging from the complete program provided, there are still some logs that can be output later. Where can I view the other logs? 

In addition, if the reference program is IPC RP Message Echo, may I ask how customer can reproduce the following log output? can you help list the specific steps for customer reference?

BR,

Biao

    To get the full log of ipc_rpmsg_echo example, please follow the below steps.

    Steps:

    • Initialize the board with SBL NULL Binaries. Please refer EVM_FLASH_SOC_INIT.
    • Open the CCS and import the ipc_rpmsg_echo project for all cores (i.e. A53, MCU_R5, C7X).
    • Build the project for all the cores.
    • Keep the board in OSPI NAND boot mode and launch the target configuration file.
    • After launching the target configuration file connect to each core(i.e. A53, MCU_R5, C7x). 
    • Load the respective binaries to each core and do a free run.

    After performing the above steps you will be able to see the output.

    Please see the below screenshot.

    For more details, please refer IPC_RPMESSAGE_ECHO.

    Regards,
