Help: A fatal error occurred: No serial data received. Failed uploading: uploading error: exit status 2

Win 11, Arduino IDE 2.1, XIAO ESP32C3

After several hours of successfully loading sketches on my XIAO ESP32C3, I suddenly got this:

Uploading stub…
Running stub…
Stub running…
Changing baud rate to 921600
A fatal error occurred: No serial data received.
Failed uploading: uploading error: exit status 2

I did not touch the R or B buttons. Tried other sketches with the same results.

Replaced board with another and have not had any further problems.

How do I “revive” this board?

Any and all help appreciated.

Have you read the wiki?

Thanks for the rapid response, MSfujino.

I re-read the wiki FAQ’s and other Q’s but nothing seemed appropriate to my situation.

Do I have to re-flash? Could you please be a little more specific as to how I should proceed?

How can I trust a board that failed with no provocation?

Revived and relieved…

Followed Adafruit “manual bootload” instructions here:

Problem solved…

I had the same problem happen when i was trying to get the Round Display to work with demo… I have used this XIAO many times with no problem so it has to have something to do with those libraries

Actually, enter the bootloader can solve the problem
