What to do with Stlink v3 mini T_NRST pin?

I want to be absolutely sure, so should T_NRST be connected to CPU reset. (In this case STM32H750.)

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

I see. The plain old reset pin. Some application notes mention also other reset signal which goes to PB4 pin. Jtag reset probably.

I normally have NRST on MCU connected to 3.3V directly. Do I need to include a pull-down resistor if also connecting T_NRST to NRST?

For example,

3.3V — [ 10k ] —- NRST/T_NRST

Excuse the ASCII circuit, I’m on my phone.
