J721EXCPXEVM: How to build a custom ipc_echo_test program？

Hello, thank you for your response. You mentioned that my compilation command was incorrect. However, I based my command on the sample provided in the documentation. Could you please clarify what is wrong with it?

In fact, I referred to Method 2 outlined in the command-to-build-ipclld document. Specifically, I used the corresponding build command for Target=example, which is: make -s -j BUILD_PROFILE=<debug/release> BOARD=< j721e_evm > CORE=<core_name> ipc_echo_test_freertos.

Additionally, I referenced the  loading-remote-firmware section, which indicates that the example name is ipc_echo_test.

Then,

I attempted the command make -s ipc_echo_test CORE=mcu2_0 in the <pdk_path>/packages/ti/build directory, but I received the following error:

Hello, I tested your solution and it works perfectly. Thank you very much for your reply.

That said, I noticed that the name of the executable generated in this way is different from the one shown in the documentation loading-remote-firmware. Specifically, the compiled program is named ipc_echo_test_freertos_<CORE>_<BUILD_PROFILE>.xer5f, whereas the example in the documentation is named ipc_echo_test_<CORE>_<BUILD_PROFILE>.xer5f.

Perhaps you could consider updating the documentation to reflect this difference and avoid potential confusion.

Now, I am trying to modify the example program to implement some custom functions. However, I noticed that the corresponding code in the PDK is quite complex, with many macro definitions and numerous global variables. Because of this, I often run into various issues when attempting to build a custom IPC test program by following the documentation writing-helloworld-app-using-ipclld.

Would it be possible for you to share a simple IPC example that is compilable and runnable? It would be extremely helpful for me to better understand the framework and move forward with my work.
