I can't upload sketches to my Arduino Nano 33 BLE anymore. I already tried this: Arduino Nano BLE 33 - serial port down (Bootloop?) - #2 by pert to no success:
❯ arduino-cli upload --port /dev/ttyACM1 --fqbn arduino:mbed_nano:nano33ble --input-dir build No device found on ttyACM1 Error during Upload: Failed uploading: uploading error: exit status 1
This is after putting the Arduino into bootloader mode using the technique described above. Yes, the orange LED is pulsating and I can see the Arduino in the board list:
❯ arduino-cli board list Port Protocol Type Board Name FQBN Core /dev/ttyACM0 serial Unknown /dev/ttyACM1 serial Serial Port (USB) Arduino Nano 33 BLE arduino:mbed_nano:nano33ble arduino:mbed_nano
Yet the upload doesn't work, failing with the error above. Is there anything else I can try? I did try with another Arduino BLE 33, which works perfectly fine.
Edit: It seems I can flash it, but only when starting the upload to ttyACM0 and then with good timing set it into bootloader mode. That's not really great. The other Arduino Nano 33 still works as expected.
