Programming a Steval-Spin3202 custom board over SWD

[TKlei.5]

Hello,

I made a custom board of the Steval-Spin320. At the moment I'am struggeling to program the board over the SWD interface. I use the ST-Link V2 programmer and the ST-Link Utility Software. I have problems connecting the microcontroller. Can anybody help me?

UPDATE: The programming over the SWD Interface works now, but the connection from the board to the pc over USB doesn't work.

While playing with STEVAL-SPIN3202 Board , I have mistakenly dump the motor program using External USB ST-LINK V2, while asked to remove protection I have selected yes.

Now connecting STEVAL-SPIN3202 board using USB PORT I am unable to detect the board.

how to detect Board again using built in USB interface, or Re-flash old firmware?
