ST-Link Mini Connections

EthanMankins · ‎2024-11-20

The STLink Mini data sheet has a pin labeled "T_NRST" I am wondering if this needs to be connected to the "DEBUG_JTRST" or the "NRST" pin of the microcontroller.

The ST LINK V3 does not support the DEBUG_JTRST signal. So, you have to do a JTAG Debug without it.

Hello @EthanMankins

The T_* prefix stands for target. It should be connected to the NRST pin of the MCU you're programming.

@STTwo-32, Thank you, that begs the question now, where should the DEBUG_JTRST be connected?
