I’m having some reliability issues with the XIAO. Just wondered if anyone else has experienced similar?
Have been able to program successfully a few times during development of a (simple) sketch, but then the XIAO stops working. Not detected under Windows until I reset it (quick double reset via the pads on the XIAO), at which point it appears as a drive letter and COM port again, but subsequent upload attempts always fail. After about 10s when uploading, the Arduino IDE eventually reports that there is no board at the designated COM port “No device found on COMx”. Sure enough, it is no longer there.
When I unplug the USB cable and plug it back in, I get the Windows “USB Device Not Recognized” balloon. Only the green power LED is on. Only the double-reset makes it appear again, and the yellow LED fades on and off, but cannot upload as before.
I’ve had this same behaviour happen on two different XIAOs now. Nothing special about the sketches, simple LED blinking and push-button detection. I’m working in an ESD-safe environment. Arduino IDE 1.8.13 under Windows 10, selected board Seeeduino XIAO.
Is this an experience others have had? Any suggestions for ways to fix? I will be trying the openocd bootloader write approach to try to fix.
Have to say I’m not happy with the XIAO as things stand.
