Resolved! ST-link V2 appears as a USB device instead of a COM PORT
Hello, Like the title says when I connect an ST-link to a computer to try to program an NRF52 through an arduino with it it won't show up on COM port but can be found in device manager under "USB devices" as can seen by this picture: How do you fix ...
Resolved! Windows command line tool for SWD viewing
Stupid newbie question: apologies if I've missed this but I'm looking for a Windows command-line tool to capture SWO output from the target, i.e one that connects to the target, sets the appropriate register bits to configure SWO output etc., takes a...

Resolved! STLINK-V3SET, No voltage on VCC pin?
Hello all, I just bought a ST-LINK-V3 set. Also, I have checked the signal on vcc pin, but there are no voltage on vcc.Is it correct?
Can send me a copy of all the data sheet and user manual for the STM32F769-eval development board?
I have a STM32F769-eval development board.I am trying to control the MB1183 camera module on the development board.I did not find the S5K5CAG data sheet and s5K5CAG user manual.Can you send me a copy of all the data sheet and user manual for the STM3...
Can connect to STM32F0 through ST-Link but not through TrueStudio/Debugger.
Hi There,I have an extremely weird problem. I have a custom PCB with an STM32F091 chip on it. I am using the SWD interface to connect. I had another board that is the exact same working and connecting perfectly. I now am trying to get this second boa...
Resolved! STM32H7A3 unusable for VGA
Getting stable V-sync and H-sync pulses is critical for clean VGA output. Getting these completely stable on the H743 was difficult and required multiple iterations of different PLL settings. but was possible.On the Nucleo-H7A3ZIQ it has proved compl...
STLINK Problem , (possibly p-nucleo bricked ?)
HiThis is the first time I`m using STM32 tools and probably made a mistake hence I can`t connect to Nucleo 68 board.When I try to connect using STLink Utility I receive22:31:40 : Can not connect to target! Please select "Connect Under Reset" ...
Resolved! NUCLEO-H745 + ST-Link Utility = Can not connect to target
Dear STM CommunityI am facing a problem with flashing/erasing STM32H745 microcontroller using STM32-ST Link Utility. Everytime I try to perform any operation I receive popular "Can not connect to target! If you're trying to connect to a low frequency...
