Hi

Could you please let me know the update of this query. Please find the link attached below.

https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/1425826/tms320f28388d-issue-with-ipc-communication-cm-to-cpu1-interrupt-triggering-only-once?tisearch=e2e-sitesearch&keymatch=%252520user%25253A620902#

I am encountering an issue with IPC communication in my code. I have configured the CM to continuously send data to CPU1 using Flag3. However, the interrupt on CPU1 is only triggering once, and I verified that the ACK flag is showing zero. On the other hand, when I perform the same communication from CPU1 to CM, the interrupt triggers continuously as expected. I have attached my code for your reference. Could you please take a look and help me identify the issue?

Best,

SaiPavan.

    Hi Sai,

    Have you taken a look at the examples included in C2000Ware for the CM IPC? c2000ware\driverlib\f2838x\examples\c28x_cm\ipc

    There is a basic example demonstrates how to configure IPC and pass information from C28x to CM core without message queues. Make sure to run the C28x1 core first followed by the CM core when executing the code.

    Regards,
