How to make UART communication over STLINK
Hi HugoARA,
I think you should find a schematics of your STM32F4xx Discovery/EVAL board and check if its design
hardware has provided some kind of connection between tht ST-LINK hardware block and the STM32F4xxx
MCU. In the STM32F746NG Discovery board there is a STM32F103 MCU that (I think) implements the
ST-LINK block functionalities. From it two lines, VCP_RX and VCP_TX come out and are connected to the
PB7 (USART1_RX) and to the PA9 (USART1_TX) of the STM32F746NG MCU.
You have to loking for the same kind of information on your STM32F4xx board.
