I have two the same board, another board did not eeprom configuration before, vivado can link to the equipment, but after the configuration also appeared in this issue, is not my configuration eeprom there is a problem?Here's my screenshot of the problem。 I hope you will solve this problem for me。

Hi @wangjianli,

You have two Port COM listed. In the USB controllers I see just 1 device connected. Do you have two boards connected on UART or just one? If it's just one you should not have two COM ports. This looks to me like you corrupted the content from the EEPROM and the board is no longer recognized. I didn't understand if this happens just on one board or on both.

I will private message you with a solution to see if we can have the board recognized again.

Best regards
