[FAQ] AM6442: [FAQ] (AM64X ) : Generating an IPC Multicore App Image for a Custom Selection of Cores

Swargam Anil

Part Number: AM6442

I want to do IPC communication between two cores, but when I am importing a system_freertos_nortos project from the below folder and compiling it, I am finally getting an app image for all cores.

C:\ti\mcu_plus_sdk_am64x_08_05_00_24\examples\drivers\ipc\ipc_rpmsg_echo\am64x-evm

I want an output for particular cores, like core R5F0_0 and core R5F0_1, not for all cores. How can I get App image for two cores ?

This section contains changes made to the IPC Notify + RP Message example to create a dual-core app image from an existing 4-core IPC Notify + RP Message example.

I am creating an IPC multicore app image for R5F0_0 and R5F0_1, and you have to follow the same procedure for the other cores as well.

This is the simplest method to create an App image for two cores from an existing 4-core IPC notify +RP message example.

This example does not involve any system projects. Hence, you have to use the command line to create a final combined app image.

I am creating an IPC multicore app image for R5F0_0 and R5F0_1, and you have to follow the same procedure for the other cores as well.

Import IPC example for R50-0 and R50-1 from the SDK as shown below.

Modify your example.syscfg to support IPC Notify +RP Message feature to the cores R5F0_0 and R5F0_1. Subsequently, disable Notify+RP Message feature for all cores .

Change the Remote Core ID List to support only core R5F0_0 and R5F0_1 in both ipc_rpmsg_echo.c files, and remove rest of the cores as shown below.

Build these projects individually. After building, we get .rprc files for both the projects.

Combine these .rprc to form a dual-core .appimage using the below command:
