JP4 NRST on STM32 Nucleo-144 boards (MB1312)

In UM2179 Rev 9 it says:

"5.4.4 Using ST-LINK/V2-1 to program and debug an external STM32 application

...

Note:JP4 NRST (target STM32 RESET) must be open when CN3 pin 5 is used in an external application."

This is CN3:

I think that should be CN5.

Yes, CN3 is a parking point for a spare jumper, and for clamping a scope probe ground.

CN5.5 is T_NRST

Also, JP4 seems like a strange choice: USB_GPIO_IN. Maybe it means JP3?
