AM2634-Q1: What is the best way to synchronize between two cores?

Part Number: AM2634-Q1

Hi there,

We plan to run two application on two cores, R0_0 and R1_0. The two applications needs to run a specific function one by one, and there will be a specific delay between to operations.

For example, App 0 on R0_0 run the operation at time 0, we want App 1 on R1_0 run the operation after 50us.

What's the best way to let core R1_0 knows when the App_0 run the operation on R0_0? so it will count 50us then run on R1_0.

thanks

    Hi Phoenix,

    You can use IPC Notify to implement the synchronization between R5F cores. See the IPC Notify example from C:\ti\mcu_plus_sdk_am263x_08_06_00_34\examples\drivers\ipc\ipc_notify_echo for details.

    Best regards,

    Ming
