Homebrew-ArmEabi

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.

Installation

• Install Homebrew
• Execute brew tap eblot/armeabi
• Install the package you need, e.g.
  1. brew install arm-none-eabi-llvm
  2. brew install armv7em-cortex-m4f

Available recipes

• 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 w/ additional tools: arm-none-eabi-llvm.rb
  • This toolchain does not require any of the GNU tools, as it comes with an integrated asssembler and linker, and the lldb debugger.
• C library (newlib 3.x) and compiler runtime for various targets:
  • Cortex-M4: armv7em-cortex-m4.rb (-lclang_rt.builtins-armv7em)
  • Cortex-M4 w/ FPU: armv7em-cortex-m4f.rb (-lclang_rt.builtins-armv7em)
  • Cortex-M3: armv7m-cortex-m3.rb (-lclang_rt.builtins-armv7m)
  • Cortex-M0+: armv6m-cortex-m0plus.rb (-lclang_rt.builtins-armv6m)
• nRF52 script to fix Nordik SDK supervisor calls: nrfsvc.py

Notes:

LLVM 9.0 series finally fixes the compiler runtime library name, so existing link command lines and/or scripts should be updated.
