See updated attachment. VREF comes from the board and goes into your adapter. |

ahh, so the difference is that pin 1 will not be connected and trst and tsrt are hard to see now (but still connected?) |

I need help with mit Segger j-link.

Also, TRST and SRST must either be connected to your JTAG adapter or pulled-up with resistors, see diagram above. |
