stm32h753 nucleo manual not have details about CN2 dfu connector

SofLit · ‎2024-10-29

CN2 is dedicated to connect to the MCU (STM32F723) that manages STLINK-V3 and update its firmware over SWD:

PA13: SWDIO

PA14: SWCLK

But I don't think user needs this connection as the firmware could be updated over ST-LINK micro USB connector (CN1) using STM32CubeProgrammer or ST-LINK firmware upgrade tool.
