STM32CubeMX2 (MCUs)

I’ve started from the LWIP TCP echo server with FreeRTOS example from ST and have made a *.ioc2 file to support that example. The issue is that I’m starting from the NUCLEO-C5A3ZG (which I’ve configured the *.ioc2 project), but intend to use a STM32C593 in my final product. My understanding was that STM32CubeMX would allow switching microcontrollers, but keeping the similar configuration settings (e.g. LWIP, FreeRTOS, etc.). I’d like to have the project required configuration settings managed in a tool like CubeMX2, but this will not be possible/feasible if I can’t make changes without having to start completely from scratch every time we make a change. Is there a setting somewhere that I’ve missed to allow switching processors? Is this a planned feature that may not yet be released? Thanks in advance.

Hi,I found the new c562 chip and for that I needed to install the latest IDE, v2.1.1I am running Debian linux (testing) kernel 7.0.10 on an AMD cpu with nvidia, driver 595.80When I installed IDE 1.19 it installed mx1 automagically if I am correct, now with 2.1.1 mx1 or mx2 is no longer automagically installed anymore. Trying to install mx1 from the command line throws an error that I do not have JRE 17 installed even though versions 17/21/25 are installed.rth@castle:~$ uname -aLinux castle 7.0.10+deb14-amd64 #1 SMP PREEMPT_DYNAMIC Debian 7.0.10-1 (2026-05-27) x86_64 GNU/Linuxrth@castle:~$ java --versionopenjdk 25.0.3 2026-04-21OpenJDK Runtime Environment (build 25.0.3+9-2-Debian)OpenJDK 64-Bit Server VM (build 25.0.3+9-2-Debian, mixed mode, sharing)rth@castle:~$ dpkg -l | grep jreii  default-jre                           2:1.25-77                          amd64        Standard Java or Java compatible Runtimeii  default-jre-headless                  2:1.25-77                          am

In a project using FreeRTOS, we had the choice in STM32CubeMX to check a box in the NVIC panel “Uses FreeRTOS functions”, see here: I would love to have this feature available in STM32CubeMX2 as well, because by default the interrupt priorities are set to 0, and therefore need to be manually set to configLIBRARY_MAX_SYSCALL_INTERRUPT_PRIORITY (usually = 5) in order to use FreeRTOS API in those ISRs.

Hello, I am using CubeMX2 Version 1.0.0 on macOS Silicon. Various software packs fail to install with a 404 error like this: Could not fetch content of pack-URL: https://developer.st.com/st-pack-server/api/v1/pack/STMicroelectronics.rot_provisioning.2.0.0.pack, got: 404 - Not Found The following packs where tested and failed: rot_provisioning eeprom_emulation mcuboot fileX usbX (now installed via local pack from https://dev.st.com/stm32pc/) Is this an error on my side, similar to the proxy or certification issues I saw in other tickets or are these packs just not available YET? Secondly, I see support packs for e.g. the L4 MCU series: "stm32l4xx_dfp". What is the point of having these packs if CubeMX2 will not support these MCUs?

In CubeMX2 when configuring the I2S peripheral on an STM32C542 running from a clock of 144MHz and selecting an audio clock rate of 96000Hz, CubeMX2 computes a nearest reachable frequency of 97826Hz (I2SDIV = 23, ODD = 0). When code is generated and run on actual hardware, the HAL2 I2S driver computes a different value of 95744Hz (I2SDIV = 23, ODD = 1). The HAL2 hardware value has less error from the desired 96000Hz than the value reported by CubeMX2, but the CubeMX2 value may be used in designing other aspects of the firmware and result in unexpected performance.    

This is a bug with the code generation with STM32CubeMX2.In STM32CubeMX2, enable the middleware FreeRTOS, and in its settings Core → Main features → Advanced parameters selector → Task statistics and run-time, enable “Generate run time stats”.This generate a function in mx_freertos_app.c:/** * @brief Function to get the current value of the run-time timer counter. * @param None * @retval uint64_t The current counter value. */uint64_t GetRunTimeCounterValue (void){ return 0;}The return type is uint64_t, but it does not match the following type from FreeRTOSConfig.h (which cannot be changed in STM32CubeMX2): #define configRUN_TIME_COUNTER_TYPE uint32_t 

Split from this post: Dear ST Technical Moderator,(mEALLEm)many thanks for your prompt answer !You actually solved my problem by using CubeMX2 tool,where one can assign selected peripheral pins (in my case COMP2 two inputs and one output)to actual package IO pins.As far as I see, CubeMX2 tool “offered” to make assignment of Comparator Plus input with one of four IO pinsCOMP2_INP:IO1: PA3IO2: PB15IO3: PC0(I want to use PA3) !and Comparator Minus input with one of four IO pinsCOMP2_INM:IO1: PC1IO2: PC5IO3: PA2(I want to use PA2) !it is stated in my text, in the very beginning !... quoteIn new design,  where planned MCU is STM32C542CCT6 device, (LQFP48 package),I plan to use internal Comparator COMP2....PA7 pin as Comparator2 Outputand pin PA2 as Comparator2 -INPut, and pin PA3 as Comparator2 +INPut.... unquoteWell, the only problem is that I did not install SW development environment yet,so, I did not use CubeMX2 tool, I was just reading the documentation, RefManual and device DS,and I d

I noticed that STM32CubeMX2 (DEBUG features page) offers only three debug modes: JTAG 4‑pin, JTAG 5‑pin, and Single Wire Trace Asynchronous.In many practical cases, developers use only the SWCLK and SWDIO lines to save pins, so the absence of a simple Serial Wire option (without Trace) seems to be a limitation of the current STM32CubeMX2 release.This option is still available in STM32CubeMX1 when working with similar MCUs, such as the STM32H5 series.Is this understanding correct?

when you enable SWD in CubeMX2 it automatically blocks the SWO pin as well (tested using C531FBP6), but I only need SWCLK / SWDIO to debug. please add a way to disable the use of SWO.

I have ordered the Nucleo-C542C board. I am waiting on the board to arrive so I thought I would setup a blinky project to test on the board. i used MX2 to setup the GPIO, clock, etc. I then imported the project int CubeIDE using the CMAKE option.Apparently there is no way to build a release file. This means I will not be able to program the board. The build hammer only shows the debug build option.Also, I do not see the .ioc file in the project tree. Apparently I don’t understand how MX2 and CubeIDE link together. If I am able to ever find the .ioc file, will it be updated if I make changes in MX2? The old version of CubeMX linked the.ioc files together. If changes were made by CubeMX, those changes were reflected in CubeIDE.As a side note, there is one aggravating minor issue with CUBEMX2. Why are all the screens so washed out and difficult to see?. Everything that should be solid black is a barely visible light colored grey. This is particularly annoying in the GPIO chip pinout view.

Hello, I recently noticed that new Packs are available for download in MX2 (2.1.0). I downloaded the Packs for one of my projects but then I realized that I have to do this for every project individually. Is there a way to download new versions of Packs only once and have them available in all the projects? Thank you,-Gil

We wanted to migrate our project to the new C5 MCU family, requiring the use of the new app STM32CubeMX2.In our project, we rely on quite a lot of features from FreeRTOS, for example the function `xTaskGetIdleTaskHandle()`.This function gets compiled only if the variable `INCLUDE_xTaskGetIdleTaskHandle` is defined and set to 1, but by default its value is 0.In our project, when used with CubeMX1, we defined this variable in a /* USER CODE BEGIN 1 */. But with th new project structure enforced by CubeMX2, we no longer have user code blocks in that configuration file, and any regeneration in CubeMX2 will override any user change (well, we have a prompt saying the file was edited, but no smart-merge).From CubeMX2, it is not possible to set this include variable (checked “Core → Advanced API Selector → More”). Therefore, the only (hacky) solution I see is to set this include variable to 1 in CMakeLists.txt. IMO, this is not a solution but a workaround.Either CubeMX2 should manage all confi

Hello, I have an application that set up TIM2 as a input capture timer that worked fine with HAL 2.0.0. After upgrading to HAL/template 2.1.0 I regenerated the code with MX2 but the code does not compile. The error occurs when compiling this line of code in LPDMA1_CH1_IRQHandler() mx_tim2.c: HAL_DMA_IRQHandler(&hLPDMA1_CH1);A different DMA channel variable is defined earlier in the file and MX2 also displays LPDMA1_CH2 as the DMA used for TIM2.static hal_dma_handle_t hLPDMA1_CH2;To make the code work I changed code in this file I had to replace LPDMA1_CH1 with LPDMA1_CH2 in several places in this file. Here is the new code:/** ****************************************************************************** * @file : mx_tim2.c * @brief : Peripheral initialization ****************************************************************************** * @attention * * Copyright (c) 2026 STMicroelectronics. * All rights reserved. * * This software is licensed under t

Dear Engineers, is there any way of routing the internal OPAMP output of the STM32C5 to an ADC directly, or can it only be wired to the COMP1 ?CubeMX2 doesnt let you pick OPAMP as an input to neither ADC nor COMP, but i did find some notes on beeing able to route the OPAMP output to COMP1 minus input in the LL code somewhere.If yes, is there a way to do this within MX2, or does it have to be written by hand in code?Also, the datasheet shows a pin output option for the OPAMPs output on PA6. I know you could route form PA6 to a neighboring ADC input capable pin, but not only would that occupy 2 pins, my PA6 is in use for UART, so not usable in my case. Thanks in advance.

Hello, In the STM32CubeMX2 v1.0.1, I've noticed an issue with the ETH1 peripheral configuration in RMII mode. The application forces the PA_10 pin to be used as ETH_CLK, even though I want to use the clock generated by the PHY and supply it to the PA_1 pin (ETH_REF_CLK). In my project, the PA_10 pin is already used.The question is, is the ETH_CLK signal on the PA_10 pin necessary in RMII configuration and should I redesign the project, or is this the STM32CubeMX2 issue ? Best regards

I have read the migration guide (Typical HAL ADC use cases for migration - HAL2 Migrator 1.0.0 documentation) as well as the article How to use ADC with STM32CubeMX2 | CommunityIn the HAL2 code, I found functions such as HAL_ADC_MM_SetConfig(), which suggests that ADC multimode/dual mode is supported by the HAL.However, when using STM32CubeMX2 (not STM32CubeMX), I cannot find any option to configure ADC dual mode (e.g., ADC1 + ADC2).My question is:How can ADC dual mode be configured in STM32CubeMX2?If ADC dual mode configuration is currently not supported by STM32CubeMX2, a short confirmation would be appreciated. Thanks in advance for your help.

I created simple project using STMCubeMX2 for MCU STM32C552. I configured the clock by choosing HSIS on System MUX.  When I compile and run generated code it ends in HardFault_Handler. When using PSIS option - the same result. HSISDiv3 clock works well. When I divide HSIS or PSIS clock by 2 on AHB prescaler it also works.   Any idea? Thank you  

I am trying to learn how to program a STM32 micro-controller, specifically a STM32C593. The thing is according to its datasheet it has Ethernet functionality, bit it is missing in the peripheral list inside STM32CUBEMX2 IDE. 

Hello, I was using CubeMX with CubeIDE and since the release of CubeMX2, VSCode is promoted as the go-to.At the same time, CubeIDE got an update to importe Cmake project. What are the plans ?Will MX2 continue to support CubeIDE with Cmake only ? Will CubeIDE project exports be added to MX2?Or will VSCode be the main target for MX2?In sumary, which workflow will be the best for future dev since ST seems to refactor its whole ecosystem ?

Hello, I noticed that when showing differences between the current and the previous generated source code the width of the source code window does not even show 80 characters even though there is plenty of room in the application window (see screenshot attached). I spent quite a bit of time looking at the HAL source code when debugging and the source code is not formatted to 80 character lines anyway. Sometimes it exceeds 80 by a wide margin.  Would it make sense to show the source code window as a popup or as wide as the application window allows?Thank you,Gil 

Hello, I was wondering where the installed software packs are stored on the disk? I would like to have a look at the content and the examples, assuming e.g. the HAL pack or the Nucleo board pack contains these examples.

Hello everyone,I’m trying to develop a new project using an STM32C552RET6 with a TFT display.I’d like to use TouchGFX for this, but I can’t find any instructions in CubeMX2 on how to configure a project as a graphical application.I saw some examples in TouchGFX Designer using the STM32C5, but I got the impression that the integration was done manually.So, does anyone know if CubeMX2 has this functionality?Thanks,Matheus  

I've noticed, that the new STM32C5xx family is not present in the STM32_open_pin_data repo. I know why (MX2 vs MX), but ST, please, keep updating this repo with the new families' data. It's a valuable database for third party tools used to allocate pins in various STM32 designs. Thanks, JW
