I have a doubt: the SRST and TRST are cross connected ? i overlayed the picture with labels, and following the wires, this is what I am ending up... Is it correct ? (follow the wire going from 10pin connector SRST that seems to go to TRST pin into 20pin connector...) Thanks |

In fact you can just leave SRST unconnected on the scope. It will power on on it's own. You just can't reset it from openOCD in this configuration. |

I can reset from within OpenOCD. If I remember correctly, I just connected the signals straight through. |

(and the TRST is still connected from 10 pin header to SRST of 20 pin header) Correct ? |
