Consult camera image problem
platform:TDA4 j721e
PSDK：rtos：ti-processor-sdk-rtos-j721e-evm-08_01_00_13

We use your company's platform and SDK, and there is a small probability that the camera application will not receive images. The phenomenon is described as follows:
After the platform is powered on for the first time, the camera application does not receive the frame rate sent by the driver.
Check the vsdk log, the driver log is normal. However, the vsdk log does not receive logs after 6.79 seconds.
Using the IPC_TEST program to test, it is found that the communication between MCU2_0 and MUP1_0 fails.
The log of the camera application shows that the capture_note takes a long time.
See the screenshot of the log for details.

Hello，
From the remote core logs (i.e. [MCUx_0], [C7x_y ] ), Do you see all the logs being printed when you run the vision_apps_init.sh?
i.e. Are all the cores reaching "App: Run … Done" ?
Regards，
Gary
