What is the difference between Nucleo-H743ZI and Nucleo-H743ZI2?
If the Nucleo-H743ZI2 is newer, why Nucleo-H743ZI is the active version? I have a Nucleo-H743ZI2 board. So, where can I find schematic and support page for Nucleo-H743ZI2?

How to get a H755ZI to run 400 MHz from the ST-Link USB Power? ACTVOSRDY flag never gets set after configuring power for PWR_DIRECT_SMPS_SUPPLY.
Hi all, I've created a few projects on a H755ZI-Q that run just fine at the default 16 MHz (I think), but I'm having trouble getting it to clock at 400 MHz. I've tried this for all of my projects which include, the Cube examples (H745), the CubeIDE N...
STM32F103 random reset
Hello, we have made a 2 layer board for a STM32f103, and apparently it works fine but we get a random resets now and then. When that occurs there is a 1 in the Bit 27 PORRSTF: POR/PDR reset flag and Bit 26 PINRSTF: PIN reset flag of the Control/statu...
Resolved! ST-LINK not listed Device Manager
I have a NUCELO-L433RC-P dev board that was working fine for several days but is no longer visible in Win 10 Device Manager. STLinkUpgrade and STM32CubeProgrammer do not find my ST-LINK. STM32CubeIDE gives the error "Error in initializing ST-LINK d...

What exactly does a full chip erase through ST-Link do? Would it brick my board?
I've been having trouble connecting my board through the STM IDE. I've decided that I want to in a sense 'factory reset' the board. Would a full chip erase do this or would it ruin my board?
