TDA4VM: J721e

Part Number: TDA4VM

Hello, TI friend,

I am currently trying to debug the camera driver module, which includes the following modules: UDMA, FVID2, CSI2RX, and CSI2TX. I have looked at the code and logs, but there are very few related log prints, making it difficult to understand the driver process. Do you have any excellent debugging schemes?

SDK Version: ti-processor-sdk-rtos-j721e-evm-08_01_00_13

    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.
