Arduino sketch compilation exits with error: avr-g++: error: device-specs/specs-cortex-m7: No such file or directory

Troubleshooting and Support
1

I’m using a 2023 M2 Macbook Pro with MacOS Sonoma 14.1.1., and Arduino IDE 2.3.6.

During any attempts compiling a sketch for the Daisy seed, it seems the IDE is unable to locate some of the board dependencies. Any help much appreciated. Additional details:

  • Compilation exits almost immediately with error avr-g++: error: device-specs/specs-cortex-m7: No such file or directory
  • Using Daisy Seed v1.2 Rev7
  • The Arduino IDE is able to see the Daisy when connected via USB
  • For STM32Duino and Daisy setup, I followed the Arduino IDE setup guide located here on daisy.audio
  • I’ve installed the STM32 Cube Programmer app as well, following this guide in the STM32Duino repo.
  • Double-checked all settings are set to the recommended values under Tools (added screenshot below)

I’ve tried the following to resolve the issue:

  • Adding the STM32CubeProgrammer dir to the system PATH (/Applications/STMicroelectronics/STM32Cube/STM32CubeProgrammer/STM32CubeProgrammer.app/Contents/MacOs/bin)
  • Completely uninstalling and re-installing the Arduino IDE, STM32Duino boards, and the Arduino Daisy library
  • Deleting the Arduino15/packages and caches dirs in the MacOS Library dir
  • Symlinking the STM32_Programmer_CLI dir to usr/local/bin as recommended in this forum thread

I’ve had luck programming Seed boards on Windows 10, but so far nothing seems to work on MacOS.

Any suggestions or thoughts on what else I can try greatly appreciated!

I just tried Arduino on my M1 Macbook Air, no problem. One thing I notice in your post is:
" avr-g++: error: device-specs/specs-cortex-m7: No such file or directory"

The Daisy isn’t an AVR, so that message doesn’t make sense. You choice for Board, Board part number, Upload method all look OK. Were those settings in use when you got the avr-g++ error?

Thanks for taking a look and your suggestion. Yes - settings identical to the screenshot are used each time compilation is attempted. I agree it doesn’t make sense, as I haven’t programmed or even selected an AVR board in the Arduino IDE on this laptop yet.

Nothing I’ve tried results in the Daisy being even close to programmable on an M2 Macbook Pro via the Arduino IDE (short of resetting the laptop completely, which I haven’t tried yet). The same immediate compilation error even happens when STM32duino is the only board package installed in the Arduino IDE, after removing the entire /Library/Arduino15 dir, as well as the /Application Support/arduino-ide/ dir. A weird and incredibly persistent bug!

Curious. Are you certain you have DaisyDuino installed?

Yes, the DaisyDuiino library is installed.
