1. Enable Debug Logs:
Ensure that debug logs are enabled in the relevant modules (UDMA, FVID2, CSI2RX, CSI2TX).

2. Print Statements:
Insert additional print statements strategically in the code to trace the flow and identify key variables' values at different stages.

3. Logging Buffer Dump:
For low-level debugging, consider dumping key buffers or structures to the console to analyze their content.

4. Hardware Event Monitors:
Use any available hardware event monitors or trace tools that the platform provides to capture and analyze events at a low level.

5. Check Configuration:
Verify that the configuration settings for each module (UDMA, FVID2, CSI2RX, CSI2TX) are correct. Misconfiguration is a common source of issues.

6. Check Dependencies:
Ensure that there are no conflicting resource allocations or dependencies between different modules. This is especially important in a multi-threaded environment.

7. Interrupts and Callbacks:
Verify that interrupt handling and callback functions are implemented correctly. Mismanagement of interrupts can lead to unexpected behavior.

8. Memory Leaks and Corruption:
Check for memory leaks or corruption. Incorrect memory handling can cause unpredictable issues.
