Hi. I am trying to program my stm32F072RB using the build in boot loader.
I connect the user USB to my PC with BOOT0 pulled high and sure enough it does detect a dfu device. (the serial number looks fishy though?)
Now if i try and connect it prompts me to disable read protection. which it does sucessfully. but then it disconnects immediately afterwards and if i try again. it will just do the same.
I think it is a driver issue but i have allready tried to change the driver using the zadig method described in other threads. with no luck.
I have hit a dead end here. hope someone can help me figure out this mess.
if you need more info pls. dont hesitate to ask.
