OSDK4.1 failed to run main_sync (main_async) sample code, how to troubleshoot?

Keywords: camera manager, gimbal manager, OSDK rotate gimbal

Suggestions:

1. Check that the dual A-USB is connected and the communication is normal
2. Confirm that the PAYLOAD_INDEX_x in the corresponding command is consistent with the physical interface actually mounted. (PAYLOAD_INDEX_0 represents the main gimbal, and so on)
3. Confirm that the function of the test is consistent with the function of the lens used. For example, to test the zoom function, you need to switch to the zoom lens.
