After sitting on the code since last year I'm happy to now be able to make the source code available under an open source license. The open source license in this case is the GNU General Public License version 3 GPLv3.
The ADuC7020 Miniboard/Minikit I bought was only packaged with a Windows version of the download software (ARMWSD.exe). As I only use Linux at home I decided to write my own download program so I could make full use of the Minikit, which resulted in the aducloader program.
The program can be download by following the link, aducloader.
