Tool/software:
Dear TI experts,
We are using the AM243x (ALV), when M4 core project runs Freertos and is multi-tasking, the IPC RPMessage task has an error (no data can be transferred between CSL_CORE_ID_R5FSS0_0 and CSL_CORE_ID_M4FSS0_0).
Because of the above issues, we currently use IPC ShareMemory for IPC communication. Engineers of Ti can pay attention to this problem.
We used CCS 12.7 and MCU+SDK for AM243x[8.6.0.45].

Hi Tushar，
What all task is running on M4F core?
In our M4 core project, we run two tasks, one IPC RPmessage and one GPIO task. In this case we found that the two tasks were not working properly. We then modified the project to keep only the IPC RPmessage task, and found that the project worked properly in this case. That is, the IPC RPmessage drive fails when the M4 core is multi-tasking, and it can only be used in single-tasking situations.
The does IPC task getting enough CPU cycles to complete its job?
Yes, our M4 project has only two simple tasks, and I think it has enough CPU cycles to run.
IPC is done using Shared memory only.
There are three IPC modes(showed below) available in AM243x MCU SDK. We found an error when using IPC RPmessage in the M4 core, There is no problem when we use IPC ShareMemory.
Regards,
Lan
