We are using STM32F091RCH7 microcontroller in our design and STLINK-V3SET programmer. A 14 pin JTAG connector is used. Pins 13 and 14, which are T_VCP_RX and T_VCP_TX have been left unconnected. Is it good to go?
JTAG pins are mapped as shown in the attachment. Please review and provide your comments.

The board version is MB1297E, my PC OS is windows 7, I successfully installed the driver(stsw-link009), but in device manager, it appears as "STM32 STLink" with a yellow exclamation mark, on the board, LD5 doess not light, LD6 keep flashing red.I che...
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?
Resolved! JTAG Boundry scan testing tool
Hii everyone,I.m using STM32F407G-DISC1 board. I've ST-Link V2 external debugger (which image I've attached) because I don't want to use onboard debugger. I want to do a boundary scan testing. Can you suggest me is there any free tool available for S...

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...
