Build environment on Mac OS X

1. Compiler

Using Mac OS X:

The CodeSourcery G++ package provides a GNU cross-compiler toolchain for ARM. The Mac OS X version is not distributed by CodeSourcery in binary form, but can be built from source code, or installed via MacPorts.

Solution 1

This explains how to build the tool chain on a Mac: Git project: jsnyder / arm-eabi-toolchain
You will probably want to add this line to /etc/bashrc, so that the tools are always accessible when you open a new Terminal:
```
export PATH=$HOME/arm-cs-tools/bin:$PATH
```

Solution 2

Install MacPorts
Install the port arm-none-eabi-gcc:
```
sudo port install arm-none-eabi-gcc
```

Another option: Installing Ubuntu Linux in a VirtualBox:

Then refer to the main Build article.

4. Deploy

Bring the r0ket into ISP-Mode: e.g. by using Method 1 (up to 30 seconds, but works always)

Power off r0ket
Press and hold button “Left”, power r0ket on
Connect r0ket via USB

Mac OS X will show a “CRP DISABLD” USB device.

Using the Mac OS X Terminal:

cp firmware.bin /Volumes/CRP\ DISABLD/

Note: Copying the firmware.bin over to the device in the Mac OS X Finder does not work.

Using the Ubunto Terminal in a VirtualBox:

Share the directory “CRP DISABLD” on the Mac OS X host with VirtualBox, e.g. using the name r0flash - it will be available on the Ubuntu guest at /media/sf_r0flash.

Copy the file firmware.bin to that directory:

cp firmware.bin /media/sf_r0flash/
