TDA4VM: IPC concurrent communication

Ni Hua

Part Number: TDA4VM

Hi engineers.

Does the IPC(inter processor communication) between main domain MPU A72 core and other cores support concurrent functions? For example, if A72 sends two rpmsg/ping-pong messages to mcu domain MCU1_0 at the same time, can it be guaranteed that the communication is correct and the timing is correct?My board is j721e_evm, and PDK is ti-processor-sdk-rtos-j721e-evm-08_06_00_12.

Best Regards!

Ok, thank you for your support.

In addition, how to determine the maximum number of concurrent communications and connections for IPC?

What is the upper limit of rpmsg performance?

Best Regards!

Hello,

Support for user-defined static endpoints and dynamically assigned endpoints.Number of static end-points limited by RPMessage_MAX_RESERVED_ENDPOINT (100) .Overall 256 is the number we can do but there can be limitations in the mailbox for concurrently.

PLease go through URL https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/08_04_00_02/exports/docs/psdk_rtos/docs/user_guide/developer_notes_ipc.html?highlight=ipc for better understanding of IPC.
