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...

Is it possible to run a program before or later building process in stm32cubeide like user options in Keil?

Resolved! How can I debug a Nucleo H7A3 with an Olimex ARM-USB-OCD-H debugger

I’m trying to see if I can debug a STM Nucelo H7A3 with an Olimex ARM-USB-OCD-H debugger. I’m have the debugger connected to the Nucelo with the Olimex ARM-JTAG-SWD and ARM-JTAG-20-10. Is there a way to tell l STM32CubeIDE to use the Olimex debugger?...

Copying files or directories from a project to my own in CubeIDE

Resolved! Where do I set the include path on STM32CubeIDE?

This really seems like a simple thing, but I cannot figure it out. I am getting a linker error "cannot find -l:libtouchgfx-float-abi-hard.a". I can see the file so I know it exists, but it's not finding it. Adding the file manually to the include ...

Resolved! Proper way to code in C++, as IOC tool won't update main.cpp but rather create a new main.c

Hey everyone,I'm trying to make a project in C++. I tried the trick to rename main.c to main.cpp with the right-click > rename function. It works, but then if I change the IOC with the config tool, it will create a new main.c with the proper settings...

Hello. How can I measure the length of an indefinite length "uint8_t"? I used sizeof() but it didn't measure correctly

I am using STM32F7 series. I created httpd server ethernet project. I have web code which html,css,js. But my microcontrollers memory not enough for these codes. I need to use SD Card.

I need to put it my web codes (html, css, js) to SD Card. Also These codes need to work on SD Card. Because my web codes memory size is around 300MB. Normally I worked my code (basic html files) without SD Card. It needs converting to fsdata.c files....

Resolved! Post Build FLASH/Memory checksum stm32cubeIDE

Hello, is there a way to calculate and display the flash/memory checksum after build for example in MPLAB X IDE there is a checksum in the dashboard (see the attached picture).

USART2_IRQHandler called continuously for DMA reception on STM32L031K6T6 with hardware flow control

Hi. I am using UART with DMA for TX and RX on STM32L031. It communicates with nRF52833 over UART with hwfc enabled. My problem is, when I receive data from nRF52, USART2_IRQHandler is called continuously. Below is the screenshot of all the flags that...
