# NabGCC
## Overview
When Mindscape released the files related to the Nabaztag:tag, they released the source code of the firmware running on the Nabaztag:tag. When we tried to use them, we faced some problems:
- The projet uses an old version of the proprietary IDE from IAR (v4.x) - It does not compile with the new version (v6.x) - The firmware is too big for the freeware version of IAR (old or new) - The source code is what I would call a big mess. - IAR is not well integrated with OpenOCD or GDB (or at least, it was not that easy to use). - IAR doesn't provide any .elf file to use with GDB, so debugging was nearly impossible.
So, I started a port of the code to be used with GCC. It's called NabGCC :)
## Get the sources
It's currently hosted on my personnal GIT server:
git clone git://git.redox.ws/nabgcc.git

## Compile
Using the makefile in the root folder, you can build the whole firmware project with just:
make
Delete the objects files, and binaries with
make clean
The objects files should be in the `obj/` folder, and the binaries in the `bin/` folder.
