STM32 Nucleo-H743ZI2 VCP Port / STLINKV3

HiI am currently evaluating the STM32H7 family on a NUCLEO-H743ZI2 board. I am having troubles with the UART. I checked the schematics for said board and it shows that the STLINKV3 on that board is connected to USART3 on the STM32H743. So I created a...

Hi,I am using STM32L431CCT6 MCU in my design. I have space limitation on my PCB and did not place pull up/pull down resistors on unused pins. Is there a problem? What is the recommendation here?

 My boot up time is about 30mSec. I would like to know how the pins behave during boot up. Does it behave as high impedance i/p or as o/p sourcing/sinking current? In my design I am shorting two IO pins. Is there a chance during boot up one can sourc...
