The XIAO device always reset

Download the program, the serial port always prints the following. What happen with it?
How do I fix this?
Maybe I should re-download the firmware? Or something else? Firmware model?

the device is XIAO_esp32s3/

Hi, seems like you need to “pet” the watchdog on the device. I do not know how to do it in that particular device, but usually you place an instruction on loop() like this:

watchdog.refresh()

(I invented that, please check the docs to find out the real command)
Best,

Hi there,
It’s a boot loop, Place it in Boot loader mode and that will stop the serial output
Then upload the blink sketch to straighten things out.

Thanks! I must recount what I did. Yes, I did the method you provided, but after burning into Blink Sketch, and then burning into your own program, the above problem still appeared. I’ve also had doubts about a problem with my program, but it was no problem to burn my own program a month ago. However, I’ve now downloaded the firmware, and I’m burning in. But now none of the Blink Sketch programs can be written.

Thanks！The problem is indeed one that I left out.

#7

What was the problem and the solution ? I have the same thing on one of my computers.

#8

NO! you may change the power supply. Pay attention to the watchdog

#9

I have new way. Arduino run on set core 1.
