Hi All,
I was working with dfu-utill couple of years ago as part of my thesis. My task was to provide a firmware upgrade mechanism using USB. I had an open moko so I thought of implementing a solution based on it. The board I used is SAM9G45 http://www.atmel.com/devices/sam9g45.aspx.
My observation in the current implementation was that, the partitions are getting listed as DFU capable devices with fixed address and to change their size or address, you need to change the u-boot-env. Considering the requirement I tweaked the protocol and some code to make a fast and flexible upgrade.
I have explained about it here http://codelectron.wordpress.com/2014/02/28/flexible-firmware-upgrade/ Header source code here https://github.com/codelectron/DFU-Tweak/
Let me know your comments and feedback about this idea?.
Thanks, Krishna
