STM32 MCUs Boards and hardware tools

Is there a way to power a nucleo 64 board from a 3V external battery without damaging the board?

Hello,I'd like to power my nucleo L152RE from a 3V external battery.I thought this should be easy but then I read that some soldering needed to be done? Is that true? I'd like to be able to power the board from an external 3V battery to use it as an ...

How to program flash directly thru SWD?

Hi, Everyone,I am developing the standalone SWD programmer operating by battery.I have a problem to program flash thru SWD directly.So, I traced SWD line with the ST-Link Utility. It looks that some tiny flash program code and updated user firmware a...

STM32H750VB custom board isn't programming with ST-Link

Hello,We've developed a custom board with STM32H750VB at the core. The relevant page of the schematic is attached. It is not communicating properly with the ST-Link on a STM32L053R8 Nucleo board. STMCube Programmer is the software used on Windows. Th...

Using the STLINK built on to the Nucleo board, can I debug an external MPU device? I am able to program an external device (with the proper jumper setting and cable connection to the target), but not able to debug. Is the debug capability not available?

STM32H745 dual-core debugging with IAR toolchain

Hi All!I am working on STM32H745 dual core controller and IAR Embedded Workbench for ARM toolchain V8.40.1 for development. I have completed all my work on individual core test and debugging with help of ST-Link V3 as debugger but unfortunately , I ...

Best design guidance for an STM32F4 microcontroller operating in both 3.3V & 5V environments?

For long term reliability and not dealing with interface subtleties I practice using 3.3V/5V translators (e.g. SN74LV1T34, ...) rather than taking advantage of the 5 volt tolerant inputs. I see this as reducing the voltage stresses & load current dr...

ST-Link's Virtual-Comport does not work when compiling the Release mode. Port itself is OK.

Hi, friends.I connected NUCLEO-F446RE to ST-LINK's Virtual Comport. And I'm controlling the Step Motor by communicating with Comport, and Comport works well in Debugging Mode. By the way, I compiled it in Release Mode and downloaded it, but Comport d...

STM32G071RBT6(Reason : (4)No device found on target.)

Hello, ​I have the following problem when using the Nucleo board.​I do not have a mini-usb.​So I use to ST-LINK.​However, the following warning message is displayed.​Please tell me the solution.​Thank you for reading.​※ I use to STM32CubeIED.​​​​

Use ST/LINK as standard SWD/JTAG Programmer

Hi :) I have a few boards - for example a Nucleo - that all come with a ST-LINK attached. They work great to program any STM32 MCU, but I was wondering if it could be possible to use the ST-LINK as standard SWD/JTAG programmer for other ARM Cortex MC...
