    Hello,

    after extensive testing and verification, I am confident that our crash (Linux stall) is not caused by writing the firmware, since, in our current configuration, only U-Boot writes the firmware. However, our application sometimes fails to work on the first boot; after a simple reset, everything functions as expected.

    At this point, I suspect a problem related to the HPS2FPGA bridge. The crash almost always occurs in code accessing this bridge, making it very difficult to debug.

    Could you please assist with further troubleshooting?

    This issue is critical for our project.

    Thank you very much.
