I am not able to update the firmware on my NDP2 to 4.3.1.0 (it's curently 4.2.0.0). I am using VS2012. I've gone through the setps in your article - I did try updating the driver to the one from DfuSe_Demo_V3.0.3_Setup_amd64, but the msg is "the best driver for your device has already been installed". The Netduino Update 4.3.1.0 just doesn't see it (window is empty). And yes, I did put the board into boot loader mode. Any help appreciated.
I also have VS2008. Will that work with firmware4.2.0.0?
