    Hi,

    Are you sure there is an issue? In order for it to be successful the PC must be receiving something back from the device and programmation should have occurred.

    What are you connected too? Are you looping back the TX to the RX? You have a wire looping back to the card. What card is that?

    If you do the loopback, the autobaud will be successful and the kernel will seem like it has loaded successfully, but it would just be due to the loopback.

    Regards,

    Because you have a loopback the PC application sees it a passing. You can see the details in the Application Report and Boot ROM chapter of the Technical Reference Manual.

    You can modify the serial flash programmer which is a Visual Studio project and the SCI flash kernel to meet your specific needs.

    Let me know if you have any specific questions.

    Hope this helps,
