I'm trying to get MicroPython running on my RP2040 Connect and am having issues. I installed the latest MicroPython UF2 (V1.19.1) and put the board in boot select and copied the UF2 to the board. I then installed the latest version of Thonney (4.0.1) and connected to the board & port. But it keeps giving me the following message when Thonny starts:
Device is busy or does not respond. Your options:
- wait until it completes current work; - use Ctrl+C to interrupt current work; - reset the device and try again; - check connection properties; - make sure the device has suitable MicroPython / CircuitPython / firmware; - make sure the device is not in bootloader mode.
Ctrl+C does nothing. Not sure why it seems to be hung up.
If I try to download my program, it says "Could not interrupt current process. Please wait, try again or select Stop/Restart!".
This is from quite awhile ago, but I spent a long time last night trying to install MicroPython on my Nano RP2040 Connect board with similar symptoms. The instructions say to place a jumper between the GND and REC pins. Then press the reset button. This creates a disk volume. When you drag the MicroPython .uf2 file there, MicroPython is installed and a different volume shows on your desktop.
Well, I didn't see anywhere in the instructions that suggested you remove the jumper between GND an REC before you drag the .uf2 file. If you don't, the installation won't complete properly. At least that was the issue for me.
I think that without removing the jumper, when MicroPython is finished installing and it does a restart, the board just goes back into bootloader mode without actually installing MicroPython.
FWIW. In case anyone else comes across this in trying to figure out their own issues ...
