LEGO MINDSTORMS EV3 source code

See the release announcement on BotBench for more information.

Things you will need

  • A Linux (virtual) installation. I used Ubuntu 13.04 on VMware Workstation, but I am sure other combinations also work.
    The reason for the Linux installation requirement is due to the case-sensitive filenames used by the Linux kernel source repository. Attempting to clone the source repository to a non-case sensitive file system such as Mac OSX HFS+ or Windows FAT would result in a corrupted repository.
  • Eclipse. I used Helios Service Release 1, but I know more recent versions will also work.
  • Java JRE (for Eclipse)
  • Code Sourcery Lite for ARM version 2009q1-203. You can download here directly.
  • The mkimage program from u-boot-tools package to compile kernel.
  • The convert program from imagemagick package.
  • A USB to serial port dongle. You need to splice an NXT cable and hook up dig0 (pin 5) and dig1 (pin 6) to TX and RX, not 100% which way around. GND is pin 2 and 3, just pick one. The brick’s console is on port 1 and has a baud rate of 115200 8N1. I have a pre-made one with an NXT socket, it’s not actually as fancy as it sounds. A guide can be found here.
  • An SD card to put your custom firmware on. It doesn’t use up a lot of space, but I’d stick with a simple 2GB one
  • A pair of flat-nosed pliers, for removing the SD card
  • A Netgear WNA1100 WiFi dongle. It is currently the only WiFi dongle that is supported by the EV3’s firmware.

Getting Started

Use Git to clone this repo:

git clone https://github.com/mindboards/ev3sources.git

The scripts in the EV3 sources expect the source code to live in a projects folder in your home directory. You will need to create a projects symlink to the ev3sources folder that was created when you cloned the Git repo.

To import this project in Eclipse, check out the Wiki article
