Why NC is written on PF0 and PF1 pins of NUCLEO H743ZI2 though it is connected to microcontroller?

[Akash_k]

I am working on NUCLEO H743ZI2 and I want to use PF0 and PF1 pins as I2C2. But on nucleo board NC is written on these pins. Can I use these pins as I2C2?

How come you have a revision MB1364B board. Mine is revision MB1364C with a revision V chip. Anyway, have a look at the attached schematics. Revision B no revision C yes, unless you put the external oscillator.

I'd be inclined to trust the board and assume those pins are not connected.

Set them up a GPIO outputs and see if you can change them, or probe directly to be certain. Schematics are also available.

PF0 and PF1 are connected. Silkscreen has been updated in later revisions.
