Windows 10 OS
Arduino IDE both ver 2.3.2 and 1.8.19 tested
Preferences correct in both versions of IDE
Correct board selected in IDE
Correct port selected in IDE
I have a XIao SAMD21 board that refuses to upload anything. It appears to be "bricked", and has never worked since new. I do have the Arduino IDE set up correctly with the correct board selected and COM7 (Seeduio XIAO) port selected. I cannot even upload the Blink or Hello World sketches, it starts to upload then hangs up and continues uploading forever. I have double clicked on the reset button (added to circuit) and changed it into bootloader mode. When I do that the COM port changes to COM6. I have deleted the CURRENT.UF2 file numerous times from that mode.
I have tried numerous other methods users report working such as holding the reset button while pluggin in the USB cable, then releasing. Still no upload, nothing changes.
One suggestion was to try to use Windows Device Manager to force COM7 to be COM6, but no description of exactly how to do this.
Error code shown below.
