I haven't messed with this board in a while but I can't get it to respond at all in Arduino IDE or Thonny(I can't remember which I used last for it but I know I put a simple blink app on there since the neo is flashing green)
After the board constantly gets a Port Busy error when uploading a sketch I try Thonny which just gives me a COMx: PermissionError, Access is denied.
Then I think I might need to reload a bootloader for Arduino IDE so I use the web esptool https://adafruit.github.io/Adafruit_WebSerial_ESPTool/, but the board in boot mode and try to connect and get 'Failed to open serial port'.
Then I try to manually use the esptool.exe that arduino IDE uses but I get 'COM9 failed to connect: Could not open COM9, the port doesn't exist'

I'm at a loss for what to try next since the board just simply won't respond to anything I try.
Also, nothing is attached to any pins since I've seen that stop sketches from uploading before.

Double check the COM port being selected.

See what COM ports are listed in Device Manager *before* connecting the QT Py. Then connect the QT Py and enter ROM bootloader mode:
https://learn.adafruit.com/adafruit-qt- ... de-3106832
and see what COM port shows up. Use that one.

Since you've already tried esptool, try testing the connection again using that with a chip_id check:
https://learn.adafruit.com/adafruit-qt- ... ct-3108538
to verify the basic connection is working.

No COM ports exist before plugging in the py.
I used a device cleanup tool and removed a lot of defined com ports so I got a new one assigned to the py in regular and boot mode but that didn't help.
Trying to get the chip_id in regular and boot mode gets the same result:

Code: Select all

esptool.py v4.2.1
Serial port COM4

A fatal error occurred: Could not open COM4, the port doesn't exist

The board must be in ROM bootloader mode (see link above) to query the chip id.

Does Device Manager show a COM4 entry at the same time you get that error message?

It turns out it was just an Arduino IDE and pc issue. A java process must have been holding things up, even in thonny. After a shutdown of all related things the board is showing back up again. False alarm :/
