NVMCTRL not declared in this scope #161

Closed VaFlyer closed 3 years ago

VaFlyer commented 3 years ago

Trying to load bootloader via Arduino sketch to a Feather M0 with LoRa, using "update-bootloader-feather_m0-v3.12.0." I'm following "Using LoraWAN and The Things Network with CircuitPython" instructions. [https://learn.adafruit.com/using-lorawan-and-the-things-network-with-circuitpython/circuitpython-installation] I keep getting "'NVMCTRL' not declared in this scope." and the upload process exits. Thinking I'm missing some step or file here. I tried commenting out the offending line but then another NVMCTL line is declared not in scope. What am I doing wrong?

Don't comment anything out. That kind of error is usually because:

Also I'd recommend installing the latest Arduino IDE before doing the above as well.

Thank you.

  • You need to set the Board to "Feather M0"; it is still some other non-SAMD board
  • You need to install the SAMD Board Support Packages. Install the Arduino SAMD package first, then the Adafruit one:
  • "Arduino SAMD Boards"
  • "Adafruit SAMD Boards"

Also I'd recommend installing the latest Arduino IDE before doing the above as well.
