Hi,
to programming my TC233LP-32F200N i would like to use the DAP interface. I bought a miniWiggler V3.1 for that and I read the manual of the TriBoard TC233 for the wiring.The wiring result is the picture below!



I had a board made for this purpose.
It´s only a try to check the DAP interface, but it doesn´t works. I dont can connect to my prozessor. The settings of the InfineonMemTool are correct and the miniWiggler works, because i tested it successfully on the TriBoard TC233 V1.1.

Did I forget anything on the board, or is the wiring wrong??

Thanks for help

As long as PORST signal is low, the DAP Interface is not working,
There is missing an external pull-up (1K ~ 2K2) on PORST. PORST has internal pull-down which is always active. Therefore the PORST is always low without an external pull-up
