RT, in the imx8qm, how does the scu interact with m4 or Acore?
In the m4 SDK, it can be seen that m4 communicates with the scu by the following APIs:
The api1: sc_misc_set_control ();After testing, the communication between m4 and scu can be realized.
Now, I want the scu would reply to m4 when it receives the message from m4. Similar logic has not been found in the SDK....so, I want to ask how does scu send messages to m4 ? Can you provide the demo?
