Hello, I am using the official serial port bootloader routine, according to
Zhca806. pdf document, burning, found that the automatic recognition baud rate has been stuck in the key writing line, but the flash is not encrypted. What's going on? Why can't I jump

    Hello, 

    The autobaud function waits for specific data (A) to be sent from the programmer to the CPU, which allows the SCI baud registers to be written properly to align with the baud rate of the programmer. Once the A is echoed back to the host to signal success, the programming can be carried out knowing that device and host are aligned on baud rate being used/expected.

    Are you saying the program is stuck waiting in autobaud function for SCI input from the host programmer? Or are you saying the autobaud is actually failing?

    Best Regards,

    Allison

    Hello, it seems to be stuck, which means the program is stuck in the autobaud function waiting for SCI input from the host programmer. The hardware used is the official c2000 board, and there are no problems with serial port sending and receiving. This interface keeps popping up. Why is this?

    Hello,

    The error response on your screenshot implies that there is an issue with the file name when using fopen(). Please check that your files are accessible.

    If the file is not able to be accessed/sent, it makes sense the program is stuck in autobaud just waiting for any data to be sent before responding (either with success or failure).

    Best Regards,

    Allison
