Rosetta, the x86_64 emulation layer on Apple Silcon doesn't seem to support an instruction the latest gcc-arm-embedded (11.x) needs. As the workaround, we install the previous known good version (10.3).
On terminal, execute the following to install the last known good version (10.3):
$ brew tap --force homebrew/cask
$ cd $(brew --repo homebrew/cask)
$ git checkout d407663b8017a0a062c7fc0b929faf2e16abd1ff
$ HOMEBREW_NO_AUTO_UPDATE=1 brew reinstall gcc-arm-embedded
$ git checkout master
Detail description on how to search for specific package in Homebrew:
$ git log --all --grep='gcc-arm-embedded'
, and you will get something like this:
