I wrote a piece of assembly code to use a button on my CORTEX-M4F board and went into Debug mode. When I ran the code the whole thing crashed, some error messages came up which I had never seen before and since then Keil hasn't been able to find my board and every time I try to run a program it says: "no target connected", "flash download fail".
Don't know what to do.
I actually have a STM32F047VG board, do I still have to go on the TI website or ST's?
Eh... Of course ST's.
If you go to TI and ask about STM32F4xx, they'll smash you into pieces.
