Error 127 - Mac Big Sur 11.2.1 Install Issue

[Isaac-Tait]

I am following this tutorial. Everything was going well up to the point where I ran make BOARD=circuitplayground_express. An alert popped up on my screen that arm-gcc was not a verified developer and so the download would not be processed. I have run into this quite a bit with Apple (I wish there was a way to turn this annoying feature off...). So, I opened up System Preferences and then Security & Privacy and on the General tab I approved arm-gcc and then attempted to re-run make BOARD=circuitplayground_express. Now I am getting this error:

Use make V=1, make V=2 or set BUILD_VERBOSE similarly in your environment to increase build verbosity.
/bin/sh: arm-none-eabi-gcc: command not found
make: *** [build-circuitplayground_express/py/mpstate.o] Error 127

I am not quite sure what to do now. Any suggestions would be appreciated 😸

Side question: I have a Circuit Playground Classic not the Express. However, if I run the command make BOARD=circuitplayground_classic I get the error:

Makefile:30: *** Invalid BOARD specified.  Stop.

Can I run a classic using the express "board"?

Cheers.

CircuitPlayground "classic", with a 32u4 microcontroller, is not compatible with CircuitPython.

[Isaac-Tait]

Okay, good to know @jepler. I will purchase an express.

I am getting a new error now.

Use make V=1, make V=2 or set BUILD_VERBOSE similarly in your environment to increase build verbosity.

gcc-arm-embedded is installed (Confirmed this when I ran --version it returns zsh: command not found: gcc-arm-embedded. So, I ran brew install gcc-arm-embedded and it returned already installed).

[tannewt]

Okay, good to know @jepler. I will purchase an express.

I'd recommend the CircuitPlayground Bluefruit over the Express. It has more RAM and bluetooth.

Can you try brew list gcc-arm-embedded (IIRC) to list the files that brew installed? Perhaps it isn't in your path.

[Isaac-Tait]

Thank you @tannewt for the suggestions. I was not aware of Bluefruit, it looks pretty cool. I will pick one up as well I think...

When I run the command brew list gcc-arm-embedded it returns this error:

Error: No such keg: /usr/local/Cellar/gcc-arm-embedded

My next thought was that I should install it, but then I came across this. So, I ran brew instal gcc-arm-embedded to see what would happen and I got this response:

Warning: gcc-arm-embedded is already installed
