Hi, Ti

I am now trying use ipc between MCUR5F, A53, DM R5F and C7x

1. I am refer the demo in SDK examples/drivers/ipc/ipc_rpmsg_echo_linux. The demo I want to refered is right?

2. And in mcu-r5fss0-0_freertos syscfg, the default config is :

A53SS0 Core0: ALL IPC DISABLED

Linux A53 IPC RP Message: Enable

PDK IPC: Disable

as shown below:

I want mcur5f IPC with A53, why first line config A53SS0 Core0: ALL IPC DISABLED?

The 5th line config Linux A53 IPC RP Message: Enable, What is it related to A53SS0 Core0?

What meaning is PDK IPC?

When the application wants to do IPC with Linux, it needs to setup the resource table which is needed by Linux.

The Linux A53 IPC RP Message checkbox option when enables generates the resource table needed by Linux. Please refer below screenshot.

Please refer below screenshot.

Please refer DRIVERS_IPC_RPMESSAGE for more info.

If you want to do IPC with A53(RTOS/NoRTOS) core not running Linux, you need to enable the above mentioned option.

This option is used when IPC is required in application developed using PDK(i.e. for MCAL).

Hope the above information helps.
