Is it possible to change the OS in the EV3 Mindstorm Brick I'd like to know how to change the OS embedded into the EV3 mindstorm Brick ( list of it ).
For example, would it be possible to replace the existing one by a linux release without losing any functionality ?

I want to to use an OS supporting all the Robot EV3 functionalities and also the 802.15.4 protocol.
This can usually be achieved on the EV3 with a bootable SD card - you would set that up with a new firmware image and a loader that copies it across to the brick.

The leJOS team have ported their codebase to the EV3 - so with a bootable SD card you can indeed load a modified version of the firmware onto your EV3 brick.

You can then use their WiFi stack to communicate with your brick via a USB dongle - whether they support 802.15.4 yet (or ever will) I couldn't say.


  The WiFi stack is loaded to allow connection to the EV3 via a supported USB WiFi adaptor. This allows you to connect to the EV3 via Telnet, SSH and NFS and makes program development very simple.
