Homebrew tap for ARM EABI toolchain, dedicated to build baremetal ARM Cortex-M applications from a macOS host.

These toolchains have been used to build eCos-based application and bootloaders, and are now used to build applications for Nordik nRF52 BLE applications, ST STM32L0 and STM32L4 baremetal and ChibiOS applications.

• Install Homebrew
• Execute brew tap eblot/armeabi
• Install the package you need, e.g. brew install arm-none-eabi-llvm

• GNU BinUtils (Assembler, Linker, Tools): arm-none-eabi-binutils.rb
• GNU C compiler: arm-none-eabi-gcc.rb
• GNU Debugger: arm-none-eabi-gdb.rb
• Clang/LLVM toolchain: arm-none-eabi-llvm.rb
  • This toolchain does not require any of the GNU tools, as it comes with an integrated asssembler and linker. Note that the linker does not support complex target.ld scripts with the stable 5.0 version. However the development version now supports most of the common script syntax.
  • Support the --HEAD option to install the development version of LLVM
• C library (newlib 3.x) and compiler runtime for various targets:
  • Cortex-M4: armv7em-cortex-m4.rb
  • Cortex-M4 w/ FPU: armv7em-cortex-m4f.rb
  • Cortex-M3: armv7m-cortex-m3.rb
  • Cortex-M0+: armv6m-cortex-m0plus.rb
• nRF52 script to fix Nordik SDK supervisor calls: nrfsvc.py
• CramFS tools to build/check CramFS volume: cramfs.rb
• eCos configuration tool: ecosconfig.rb
