Source code is based on gcc port by Martin Thomas of initial Atmel provided code sample. Martin has relased the source code into public domain and an outdated version can be found here. The original location of the sourcecode is no longer available Atmel IAR source code can be found here
Current project only makes use of a subset of the original code, mainly the BSP/drivers, as the final functionality is different.
