STM32CubeIDE 2.0 release - early heads-up!

Starting from the release in November 2025, STM32CubeIDE and STM32CubeMX will be available exclusively in their standalone versions. STM32CubeMX will no longer be integrated inside STM32CubeIDE. Instead, the two tools will be interoperable in the sam...

Why does the STM32Cube IDE shows the error "Failed to start GDB server" when debugging/running a simple project for blinking a blue pill's LED

I was going to blink my blue pill (STM32F103C8T6) LED using this tutorial but when hitting the debugger (time 5:50 of the link above) I face the following error:The strange thing is that the IDE recognizes the st link v2 and I can upgrade its firmwar...

CORDIC EXAMPLE

Hi,I was just looking at an example in STM32 IDE of using CORDIC to calculate SIN and COS. The same is explained in the document below:https://www.st.com/resource/en/application_note/dm00614795-getting-started-with-the-cordic-accelerator-using-stm32c...

Can someone point me at a Cube test project that uses mDNS in LwIP?

I'm having problems getting mDNS going on my board (Nucleo 767ZI). Can someone point me at a test/demo program using Cube that has a working example of getting mDNS going? Another service (echo even) would be a bonus.I figure that I'm missing some Lw...

Difficulty porting Keil to CubeIDE, can't add a file

I have a STM32G431 project that was originally created with STM32CubeMX using HAL drivers. I need to port some of this code to another project that was originally built by CubeMX using LL Drivers by another engineer.The specific problem I have is my ...

Resolved! MCU stuck when convert point to double

There is a array:uint8_t dat[8] = {0xcd, 0xcc, 0xcc, 0xcc, 0xcc, 0xdc, 0x5e, 0x40};It means a double variable data in memery. The value is 123.45. This code can be run in my computer: int main(int argc, char *argv[]){ uint8_t dat[] = {0xcd, 0xcc, 0x...

Early resume button press causes stm32cubeide to fail

HiUsing a G474 nucleo board and building a project and launching it everything works fine if I patiently wait for the debug session to be halted in the beginning of main(). However, if I instead hit the resume button maybe a second too soon, I instea...

Resolved! Unable to perform JTAG programming and debugging in CubeIDE and STLink V2

Hi all,I'm using STLink V2 (Not STLink V2 ISOL) to program and debug a STM32F103C8 microcontroller(Development board is a low cost STM32 bluepill). Programming and debugging via SWD works like a charm, without any issue. But I was never able to get ...

While opening the new project, I am getting the error like "Error downloading the following files: mcusAds.json(HTTP Access Forbidden". Kindly help me.

Resolved! How to use headless build for continuous integration?

I'd like to check if any pull requests break the build by automatically running headlessbuild as part of CI.Unfortunately, there's a critical flaw with how STM32CubeIDE projects are setup, which makes this impossible.The headless build depends on con...
