Hi Guys,
I have been playing with my STM32F4Discovery board for a few weeks now using the provided programs, but now I wrote one of my own and can not get it to work.
I am using some of the files form the IO_Toogle example, the program is compiling and Linking fine with no errors at the end. I have selected the STM32F407VG as the target.
When I try to load or even erase I get this error message: "Unknown Target Connected". same if I try to initiate a debug session.
When I try to run the original IO_Toggle program, it loads and runs perfectly.
I am at a loss here...
Any Help will be much appreciated, as I am pulling my hair out.
Best Regards
