After it my MacBook wrote the following message: Usb Accessories disabled Unplug the accessory using too much power to re-enable USB devices.
I can’t reset XIAO anymore and there is no XIAO in the ports list in Arduino IDE or in VS Code + PlatformIO!
The light does not come on when I short the reset contacts!
Hi,
Please tell us about your situation.
1.Can other USB devices be successfully connected to the USB port of the PC?
2.Will XIAO get hot?
3.Does the green LED on XIAO light up?
4.Specifically, how did you short-circuit which 5V and which GND?
5.Is 5V supplied from both the USB connector and the VCC pin as shown in the picture?
It was a short time. Something may have happened after uploading the sketch. I read on the internet that connecting of 5V and GND shouldn’t harm microcontroller
Yes, electricity comes from VCC, pins work
Previously, I had to reset XIAO before each new upload of a sketch, because Arduino IDE doesn’t see XIAO after new uploads and you need to reset XIAO before uploading. Now I can’t upload a sketch because reset stopped to work
What do you connect the VCC pin to and what do you connect the GND pin to?
Is it possible that something you connect to is broken?
First connect only XIAO and USB. Does the orange LED blink slowly after double reset? Double reset is not easy to succeed. Please repeat it many times.
If the orange LED does not blink slowly, the bootloader may be corrupted.
