Welcome to the TI E2E forum. I hope you will find many good answers here and in the TI.com documents and in the TI Wiki Pages (for processor issues). Be sure to search those for helpful information and to browse for the questions others may have asked on similar topics (e2e.ti.com). Please read all the links below my signature.

We will get back to you on the above query shortly. Thank you for your patience.

Thank you.

Note: We strongly recommend you to create new e2e thread for your queries instead of following up on an old/closed e2e thread, new threads gets more attention than old threads and can provide link of old threads or information on the new post for clarity and faster response.

Hi user4358345,

I would recommend you to have a look at the image processing demo code of C6678 EVM which uses the MessageeQ method.
The demo which I refer here belongs to processor SDK . (processor_sdk_rtos_c667x_2_00_01_06\demos\image_processing\ipc\evmc6678l\master\no_instrumentation).

In the "mcip_process.c" file of the master code, you will observe the sequence of code which sends and receives the messages through messageQ. compare the sequence of your code with that code.

By the way, is it your own code or the TI released code? If it is TI released, please specify the package name and the version.
