I CAN NOT DEBUG STM32F407 ?

[MDaya.2]

There is St-link embedded for the stm32f407 card, but I don't know how to use it, is st link v2 still required to debug it? Please help I'm going crazy.

If I'm not mistaken that's a MINI USB, the MICRO USB is at the SOUTH END of the board, and connects to the STM32F407, and not the ST-LINK.

Don't use charging cables.

Use Device Manager to check/confirm that the board is found, and drivers got loaded.
