Hi, Using CubeMx and the STM32H753, when I configure for 5 pin JTAG, JTRST is on PB4. We thought that it should go to NRST. What is the correct connection for JTRST?

And from ST documentation on the STM32G4:

Page 6

NRST is cpu reset.

JTRST is jtag /debug connection reset.

your thought wrong.

why dont use SWD or trace asyn.Sw ? need old standard jtag ? then jtrst -> jtrst debug probe.

I would connect NRST to a debug header, but it's not the same as JTRST
