As I promised last time, I’m going to continue with st-link programmer clones. This time I wanted to use mbed which has some ready made libraries for utilizing USB and since it was very comfortable to use DFU upload with arduino library, at first I checked if it is usable with mbed too.
If you are interrested in security devices this post may be for you. Recently I’ve found a software which makes a GPG security device out of a STM32. It’s called Gnuk. You just need a compatible board, programmer, flash the firmware and you are ready to go. I was just hoping to find some cheap device to flash to play with it.
