STM 32 Nucleo. F7 and H7 Connections

[DeryaVar]

Hello again.

İ wrote a Python book, but I am new in STM32 boards. I am trying to learn.

I bought a 

"STM32 Nucleo F7 56ZG(216 MHz)" board

and a "STM32 Nucleo H7 53ZI" this week.

When I connected the USB socket at the ST-link side to  the USB socket of my computer via an USB cable, there was no led light of the board.

 

Both  boards behaved like this.

There were no led lights on them.

What should I do?

Should I connect both USB ports on a board to the computer at the same time?

Thank you from now on.

Hello ​@DeryaVar and welcome to the ST community,

First you can refer to the UM1974 of the STM32 Nucleo-F756ZG board and UM2407 for the NUCLEO-H753ZI

Second, you need to ensure you are using a data cable and not a charging cable as well as the USB port you are using on your PC to connect the boards.

Also check the jumper position of the power supply. For example for Nucleo-F756ZG, check that JP3 is fitted on U5V position:

Hope that helps

Have you installed drivers for ST-Link? These drivers are usually installed with other ST software: CubeProgrammer, CubeIDE, and also there is a standalone ST-Link driver installer.
