STM32 MCUs Boards and hardware tools

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...

STLink-V2 appears to reset running code when plugged in to Target

I am currently trying to track a bug in my code running on a STM32F091 MCU that causes my outputs to be really "wrong" after a random amount of time. I have 4 targets running the same code and when one "fails" I'd like to be able to plug in the debu...

Where can I buy legit STM32-development boards? (Sloved)

I'm a Power Engineering student, so my knowledge of this topic is quite limited.But I have done some simple work with some Arduinos and my plan was to take it to the next level. The STM32! So I get an ST-Link V2, and a STM32f103C8 also known as a blu...

SWV can’t be used with nucleo-32 STM32F303K8

I am using nucleo-32 STM32F303K8 and want to graph variables with a debugger like this tutorial.https://youtu.be/eumKLXNlM0USimilar questions have been posted in the past.https://community.st.com/s/global-search/nucleo32%20swvSWO pins need to be conn...
