ST-LINK provides 8.08 MHz instead of 8.000 on new nucleo-H743ZI2.
Seems there is an error in the STLink firmware (upgraded to the latest version just now), clock is off about 1%.

In the schematic of STM32F030F4, the capacitor values are written 104, what is the unit of it?
I chose STM32F030F4 as MCU for my device. I have gone through its schematic (attached for reference). I have little doubt about it. The capacitor values are written 104, that's it. Please help me find its unit, I will be too much helpful.Secondly, I ...
Decoupling capacitor on STM32H7A3NG
Messrs ST,my customer has asked to me to replace their actual microcontroller with STM32H7A3NG: the more difficult thing is the placement of decoupling capacitors because their placement is not permitted on the bottom of the PCB (as best practice for...
Resolved! STM32CubeProgrammer doesn't program the Nucleo-H745ZI board reliably
I developed a stm32 project for the Nucle-H745ZIQ board with stm32cube ide, there's no issue downloading the code from IDE using its debugger. However, when I tried to download with stm32cube programmer, the code doesn't run (no expected actions can ...

POR using ST-LINK CLI after setting option byte
hi, I'm preparing the production tools for STM32F4 using ST-LINK V2 + ST-LINK_CLI.exe. Unfortunately after setting option byte (ST-LINK_CLI.exe -OB RDP=1) the power off-on cycle is required to start cpu. Is there a way to do POR using ST-LINK V2 + ST...
Resolved! Virtual COM port: LPUART or USART on Nucleo-144 board (MB1361)
Hello,I was wondering if anyone has used the STM32 Virtual COM Port (VCP) on the Nucleo-144 board (MB1361) with USART or LPUART for printf debugging. As far as I can understand, PG7 and PG8 are connected to VCP through ST-Link. In this case, the outp...
Store Codes in the Flash Memory in the STM32
Hello,I am using stm32f767 as a microprocessor. After power off, the codes are deleted from the microprocessor. But when I checked with the STlink Utility, I saw that the codes are stored in the Flash memory. Is the reason of non operative processor ...
