Raspberry Pi PICO keeps reporting the error "Device is busy or does not respond. Your options:" [Copy link]

 

When using thonny IDE to connect to pico, it will show

Device is busy or does not respond. Your options:

- wait until it completes current work;
- use Ctrl+C to interrupt current work;
- use Stop/Restart to interrupt more and enter REPL.

Then the stop button doesn't work. The following error is reported. Does anyone know how to fix this?

Is the firmware downloaded?

The device is busy or unresponsive. This situation is also related to the driver

I also encountered this problem when I downloaded the firmware on ESP32 cam
