TDA4VM: IPC echo test fails to register mailbox on C66x and C7x

Hello Support Team,

I am recently switched to psdk_rtos_auto_j7_07_00_00_11. When I am building and executing the ipc_echo_test demo, I find the following output in the trace buffer:

IPC_echo_test (core : C66X_1) .....

I used the following command to build the image:

make -s ipc_echo_test DISABLE_RECURSE_DEPS=no OS=linux BOARD=j721e_evm CORE=c66xdsp_1

The C7x image reports the same error.

How can I fix this error.

Thanks in advance and best regards,

Marco
