Hi,

Before you update the firmware, you should use jumper to connect jp5. When update successfully, remove it.

thankyou a lot  ,  i tried it again, but it showed me another problem. sorry ,could you tell me how to deal with it?

Hi,

This is the problem of the PATH environment variable. Adding the directory of the windows command to the PATH will overwrite. That is: append to the path: %SystemRoot%\system32;%SystemRoot%;

Hi,

Does your board work well? Can you download the program? If you do not connect the board, then press 'space', does it show something?

Have a great day,
