All the tools can be installed using Homebrew or MacPorts:
$ # GDB $ brew install arm-none-eabi-gdb $ # OpenOCD $ brew install openocd $ # QEMU $ brew install qemu
NOTE If OpenOCD crashes you may need to install the latest version using:
$ brew install --HEAD openocd
$ # GDB $ sudo port install arm-none-eabi-gcc $ # OpenOCD $ sudo port install openocd $ # QEMU $ sudo port install qemu
That's all! Go to the next section.
