Pretty cool, however I ended up just using brew install caskroom/cask/gcc-arm-embedded, which is working well for me.

@chris-zen There's no easy solution from the best that I can tell. I've tried building that toolchain using crosstool-ng and have not had success yet.

This worked exactly as you described. Thank you!

lukaszmargielewski commented Jan 17, 2018

Maybe I am missing something but why not just download pre-build and validated toolchain from the ARM dev portal?:

tntclaus commented Mar 25, 2018

@lukaszmargielewski that's exactly what brew install caskroom/cask/gcc-arm-embedded does :)

The last two comments were pretty useful. I could understand downloading the binaries and putting them in the /usr/local directory and setting your PATH, however I had no idea what home-brew would do to install things, where it would put them, or whether the version it would install will be the same one.

So while I did download (but did not install) "gcc-arm-none-eabi-7-2017-q4-major-mac.tar.bz2", I decided to try the "brew install caskroom/cask/gcc-arm-embedded" first.

This worked. The cask room formula is here, which is pretty readable, and it just downloaded the same file as I initially downloaded manually:

gcc-arm-embedded was successfully installed!

So I learned something about home-brew as well as got an easy install.

After this install, all the documentation is under:
For example:

Example code and example startup assembler files for M0, M3, M4, M7 are under

The next thing you're going to need to do however is download and install CMSIS, the ARM CPU common headers and run time libraries.

Lastly you're going to need the header files for the peripherals from the manufacturer of your specific ARM part.

Hello @Markrus. I am wanting to make a custom version of the inav firmware based on the latest MATEKF405SERVOS6 build. This link is where I found out that what I want done to the firmware (set up motor pads for servo signal) can actually be done: iNavFlight/inav#3140

I am on a Mac and have begun following the steps listed in this link:

I am at the place where I should install the GCC. This is where I don't understand how to proceed. I have not done any coding in forever and I'm unsure how to enter the commands correctly. I have created a folder in my User folder called "Development". The latest GCC tarball is there and I unpacked it into the same folder by double clicking it. I now have a folder entitled "gcc-arm-none-eabi-8-2018-q4-major" inside the "Development" folder along with the original tarball. My User folder is called "gerelmcintosh". The path to the GCC tarball and GCC folder is gerelmcintosh/Development. How would l word the command in the Nano program running in my Terminal to get the GCC "installed"?

Thanks @markruys, I ran brew install px4/px4/gcc-arm-none-eabi which worked just fine for me.

There are a number of solutions in this thread, but the official download from brew and ARM with :
brew cask install gcc-arm-embedded

is by far the simplest and easiest.

curtisembedded commented Mar 20, 2020

The correct command to install gcc-arm-embedded is: brew install homebrew/cask/gcc-arm-embedded

The install works great. However when it is done the compile is unusable due to MacOS security. Is there a way to bypass the new security in Catalina?

Works as expected on Mac M1 (cask installed from a Rosetta brew - i.e. arch was i386 to ensure placing in /usr/local/bin and not in /opt/homebrew/bin).

brew cask no more works after 2022.
Instead, use brew install gcc-arm-embedded --cask to install.
Thanks @jeremyheiler anyway.
