Hello,

We do have ipc_echo_test in pdk folder which can be used to run as application on R5F side for communication between R5F and A72.

On A72 if it running linux, then we can use rpmsg_char_simple for communication.

To help you further,can you mention which R5F core and what HLOS you are planning to run on A72?

Regards

I have built an app as a demo and there I have added the code for ipc nptify between two cores, so is it the correct way to go through?

MCU1_0 > R5F core you are going to communicate through IPC
In Linux running A72

This is the rtos sdk link :www.ti.com/.../08.06.00.12.
Have built one app and updated the code and enabled ipc notify between the R5F and A72 cores. This what we have done

yes you can do that , even we have an example ipc_echo_test available in SDK which communicates with R5F cores and also A72 running linux.

As i mentioned above , have you had chance to look into the example and run at your end ?

Hello,

NO need of linux SDK to build, rpmsg_char_simple is userspace example and you can run from the command terminal itself.

Have you looked into https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/11_00_00_06/exports/docs/pdk_jacinto_11_00_00_21/docs/userguide/jacinto/modules/ipc.html ?

If not ,please have a look it will have step by step guidance.
