STM32CubeMX (MCUs)

When I open the official example using the example selector, CubeMX cannot display the graphical configuration of that example. I would like to know if it is possible to display the graphical configuration of the example in CubeMX. Thank you very much, because that would make learning much easier.

Hello!I tried to generate the code for SDMMC using CMake, but was facing an error that did not let me finish building the project. The error was:".../FileX/Target/fx_stm32_sd_driver_glue.c:40:(.text.fx_stm32_sd_init+0xc): undefined reference to `MX_SDMMC1_SD_Init'".Also, using ThreadX and FileX. In FileX I enabled the setting "FX Driver Initializes the SD IP" (set to true).I saw that the MX_SDMMC1_SD_Init function is inside the main.c file, but it is declared with the "static". So, right now, to be able to build the project with CMake, I need to manually remove the "static" from the MX_SDMMC1_SD_Init function definition in main.c file.

STM32CubeMX v6.16.1 has a small bug. Under Project Manager - Code Generator - HAL settings is an option to pick under which context the free pins should be set as a analog. I am using STM32N6 which has 3 contexts (FSBL, App, ExtMemLoader).The problem is that CubeMX doesn't store (or recall) this setting. I want to set them under Appli, but on every program start it sets the context to FSBL. After doing same "fix" for tens of times it gets quite annoying.

Hi,I'm building a BLE application using custom template in STM32CubeMX. I have two services. The first one has only one characteristic with the properties "Read" and "Write without response". The second service has two characteristics, both with "Read" and "Notify" properties.The code generated in "custom_app.c" have the function:void Custom_<Srv2Char1>_Update_Char(void){...} void Custom_<Srv2Char1>_Send_Notification(void){...} void Custom_<Srv2Char2>_Update_Char(void){...} void Custom_<Srv2Char2>_Send_Notification(void){...}However, no function is generated for the characteristic of the first service. I expected to have a function like this:void Custom_<Srv1Char1>_Update_Char(void){...} I performed some tests:Used shorter names for the characteristics.Created two new characteristics, one in service 1 and the other in service 2, both with only the "Read" property enabled.In both cases, no "Update_Char" function was generated.I don’t know if this

Hello, It seems that the pin for TIM1_CH3N  should be PE12 as per schematic but CubeMX shows it as PB0. Please correct it and let me know how to fix it at my end for time being. 

CubeMX 6.16.0's "Memory Management" Tool assumes Rx_PoolSection size to coincide with the Eth "Rx Buffers Length" - is that correct? I used CubeMX 6.16.0 to create a project for an STM32 H755ZI-Q.Then I opted to use the Tools -> "Memory Management" tool and afterwards enabled the ETH [ethernet] component. This automatically generated the required sections in the "Memory Management" tool. Great.Then I enabled LwIP [with RTOS and CMSIS v2] and generated code.Compiling this code worked - linking however did not. It told me the contents of Rx_PoolSection were too big, i.e. the section too small: EBoxNG3_CM7.elf section `.Rx_PoolSection' will not fit in region `Rx_PoolSection'region `Rx_PoolSection' overflowed by 225668  The buffer for the RX_POOL is declared in CM7\LWIP\Target\ethernetif.c:98:#define ETH_RX_BUFFER_CNT 12U LWIP_MEMPOOL_DECLARE(RX_POOL, ETH_RX_BUFFER_CNT, sizeof(RxBuff_t), "Zero-copy RX PBUF pool");with__attribute__((section(".Rx_PoolSection"))) extern

Hello,I was using STM32CubeMX, but starting two days ago, when I launch the program, only the splash screen appears and the STM32CubeMX does not proceed any further.1. I have tried deleting the program, restarting the computer, reinstalling it, and running it again.2. Adding a new user is not possible; the user creation permission is restricted to the company's IT administrator.I would appreciate any suggestions on additional steps I could take to resolve this issue.

I have a Discovery board B-L072Z-LRWAN1 and I am trying to set up a project using CubeIDE but get the following, So I check to see if the L0 & LRWAN packages are in the repository, Yes, they're there. I click OK & Cube carries on setting itself up & up pops the ioc window. I press configure & generate & get some C code but the build option is greyed out.   What am I missing here?      

We have a board with a stm32u5. were VDDIO are connected to 1.8 V and  the I2C bus have pullup to 3.0 V. Some I2C devices uses 3.0 V logic levels and som 1.8 V. Between which voltage levels shall i measure the rise and falltime that i enter in cubemx. 30%->70% of 1.8 V or 3.0 V .We have possibility to turn off and on some devices on the bus that changes the rise and falltime on the bus. Shall then the longer or shorter rise/falltimes be used?One reason we are asking is that our design engineers wonder why the signal of the clock never is piece wise equal in on and off timing as it is the case with other I2C masters 

Hi there,I'm using an N6 with the latest version of IDE and MX with the FSBL/Appli dual project structure as per the FSBL LRUN template, and MX is incorrectly managing code. When using X-CUBE-FREERTOS in Application mode, code generation and cleanup is buggy. I've attached a FreeMarker template error generated WITHIN app_freertos.cWhen removing FreeRTOS from the project, MX fails to remove void MX_FREERTOS_Init(void); and MX_FREERTOS_Init(); from main.c. It also doesn't remove the head app_freertos.h and FreeRTOSConfig.h header files, but does remove the source file. I get the following compiler error:make[1]: *** No rule to make target '/Users/h7/STM32CubeIDE/workspace_1.16.1/N6Project/Appli/Src/app_freertos.c', needed by 'Application/User/app_freertos.o'. Stop.I'm also finding that the files that I have added to the build exclusion list in libraries that I've included in Middlewares/Third_Party are being reset. After a code generation, those files that MX should not be touc

Hello,I have observed this issue in version 6.16.1 across several MCU series (F3, F4, H5, H7), though it appears likely that all earlier versions are affected.The generated .cmake toolchain files incorrectly treat the --specs=nano.specs option as linker-only. This option should be applied globally, as it also affects the system include paths used during compilation. Specifically, it causes the compiler to include arm-none-eabi/include/newlib-nano/newlib.h instead of the standard arm-none-eabi/include/newlib.h.While this mismatch probably does not break ABI compatibility—since the structures provided from the standard headers are larger than those used in the compiled newlib-nano library—it does negate the RAM usage benefits of newlib-nano. This is particularly problematic when using the USE_NEWLIB_REENTRANT FreeRTOS option.Regards,Peter 

The application bundle contains Contents/MacOs instead of the required Contents/MacOS. On case-sensitive file systems, this prevents LaunchServices/Finder from starting the app.The binary runs correctly when launched directly from Terminal.Renaming MacOs → MacOS also seems to solve the issue.Seems to be an error in the ST packaging system.

"I am generating code using STM32CubeMX for the STM32WB09, aiming to implement BLE with CMSIS-OS.I am facing an issue where, even after explicitly disabling the Sequencer when enabling CMSIS-OS, CubeMX still generates code that relies on the Sequencer. This results in an application with multiple errors.Upon checking the official examples at https://github.com/STMicroelectronics/STM32CubeWB0, I noticed that the projects utilizing RTOS do not seem to rely on CubeMX (the .ioc files are missing).Is there a known limitation or bug regarding this behavior in CubeMX?"

Hi,I'm probably doing wrong as a newbie in STM32 programmation:I try to generate this configuration code for dma but I can't see any dma.c file in the project folder.(I did refresh the project after generating the code)Thanks for help  

Hi, I found a small bug in STM32CubeMX for STM32WL55:Enabling the option "MSI Auto Calibration" for section "RCC" does nothing, i.e. generated code doesn't change.I think it should add a call to HAL_RCCEx_EnableMSIPLLMode() or LL_RCC_MSI_EnablePLLMode () in SystemClock_Config() - same as it does for STM32U0. This enables RCC_CR_MSIPLLEN.

Hi there,I found an issue with the CubeMX 6.16.1 during the TouchGFX usage. I generated the files by TouchGFX 4.26 (selected the Stm32h7s7 development board with 24bpp project) and opened the cubemx to generate the code (I've been using vscode so I changed only the toolchain/IDE to Cmake and and with these settings the project was flashed and worked everything correctly.However, when I wanted to use the generate perpheral initialization as par of 'c/h' files and screen was struggled and couldn't read it's content. Nothing else was changed. In the visual studio I cleaned and rebuild the project but it did not work at all.Would it be possible to solve this?Thank you in advance!

The erroneous configuration in the tx_initialize_low_level.S is this: LDR r1, =0x40FF0000 // SysT, PnSV, Rsrv, DbgMThe tx_initialize_low_level.S file is generated upon selecting ThreadX 'Core' in the STM32CubeMX v6.15.0, and the above line is thereafter never changed. Specifically, upon enabling 'Enable BASEPRI support' and selecting a very common value of 5 for the TX_BASEPRI_VALUE, the above line is not updated accordingly. Not syncing the SYSTICK IRQ priority with the TX_BASE_PRI_VALUE of course leads to a system failure.This issue can be duplicated by creating a brand new project with STM32CubeMX v6.15.0 and it can be seen in the sample projects included in the Applications/ThreadX in the STM32Cube_FW_U5_V1.8.0

Hi all, I am trying to get a zephyr project running on an STM32N6570-DK, including Camera, NPU, VENC and Ethernet.I have been using STMCubeMX 6.16.1 to create the project based on the provided DK default settings.For the Ethernet block, the configurator shows pin conflicts, I double-checked and the pins are not in use by the Ethernet driver:There are similar warnings for the SD/MMC2 block:Am I missing something here or can it safely be ignored? Simon

CubeMX 6.16.0 "Memory Management" used for ethernet and with enabled linker file generation creates the following [ORIGIN adapted from default]:RxDescripSection (rwx) : ORIGIN = 0x30040000, LENGTH = 0K TxDescripSection (rwx) : ORIGIN = 0x30040060, LENGTH = 0K Rx_PoolSection (rwx) : ORIGIN = 0x30040200, LENGTH = 1KWhat I would have expected was:RxDescripSection (rwx) : ORIGIN = 0x30040000, LENGTH = 96 TxDescripSection (rwx) : ORIGIN = 0x30040060, LENGTH = 96 Rx_PoolSection (rwx) : ORIGIN = 0x30040200, LENGTH = 1536[with just 1 ETH RX buffer - see this other post ].Can someone explain to me whether this is intentional - maybe because of a constriction with the MPU granularity?Or whether CubeMX handles this wrong and should allow sub-kilo-byte granularity?Best regardsJohannes 

Using latest STM32CubeMX version 6.16.1 on STM32N6570-DK. It is possible to assign peripherals like UART, I2C, etc. into multiple contexts - boot, app, memloader, but I cannot find a way to assign plain simple GPIO's into multiple contexts. CubeMX only allows to pick Free (which means none) or one of them. Needless to say, I would like to use same LEDs and buttons from multiple contexts. I don't think the RIF is the cause, not using it right now. Seems like a missing feature. 

Hello!I wanted to set up some settings from CubeMX, specifically NX_IP_PERIODIC_RATE in NetXDuo and Rx Descriptor Length in ETH section. NX_IP_PERIODIC_RATE default value is set to 100, but when I set it to 1000, the value does not change when re-generating the code.Rx Descriptor Length default value is set to 4, but when I set it to 8/16/32, the value does not change when re-generating the code. Right now, whenever I re-generate the code, I just manually change these settings in my code due to these settings being set to their default ones. The same problem occurred in CubeMX version 6.15. One thing to point out also, is that the settings I changed are not set back to their default ones in CubeMX, only in the generated code. Also, no errors or warnings are displayed.Is this a bug or am I supposed to do something else before being able to change and apply these settings?

Despite enabling ADC, the ADC clock option is greyed out for MCU STM32G0B1KBUx. I'm using version 6.16.1

Howdy!I'm encountering a peculiar issue using STM32CubeMX ( version 16.6.1 ) and configuring the I2C1 peripheral with firmware version STM32Cube FW_G4 V1.6.1.In short, I'm trying to configure it for SMBus-two-wire-Interface, but this option fails to appear in the drop-down, only making SMBus-Alert-Mode available. This is a problem since the alert pin is already being utilized for a different purpose.This appears to be true for all the I2Cx on this device, and in desperation, I checked a handful of other STMG4x microcontrollers, and this issue remains present throughout. Additionally, I randomly checked STM32H7x, and it appears these did NOT share this issue, with the SMBus-two-wire-Interface option appearing as expected.We have a client with a tight deadline, and using SMBUS is essential. Any updates on when this could be fixed, or workarounds would be greatly appreciated.Thanks a million in advance!

Hello,Due to limitations with the STM32WBA's silicon & Bluetooth stack we've had to significantly re-engineer our hardware and add an external Bluetooth chip. As part of this, we updated our SAI blocks so that one block is transmit and one is receive, and moved our PDM microphones to a SPI bus.Since we have two PDM microphones, we've followed AN5027 "Interfacing PDM Digital Microphones":In our setup, we have SPI2 SCK (mapped to PB10) connected to PA1, and connected PA9 to the DMIC_CLK line. Our plan has been to map PA1 (input) -> TIM17_CH1, which then triggers (via ITR8) TIM3_CH2 which is mapped to PA9 (output).However, I'm struggling to set up the signals properly. I am able to configure TIM17_CH1 so that I can count SPI2_SCK. However, I am unable to trigger TIM3 to count at all.I've attached my example project for the NUCLEO-WBA65RI board.Any insight on this issue?Thank you,Jonathan

Hello,I searched on Google but I don't know if anyone has encountered this problem before. As we know, CubeMx and Cube IDE were recently released as two separate programs. I think this error might be related to that.The error is this: I open a project I created in CubeMx in the IDE and upload it to the chip; there's no problem up to this point. However, whenever I make an update in CubeMx, the entire update isn't reflected in the IDE (or rather, in main.c). If there were no updates at all, I would look for the problem elsewhere, but some of the configuration settings are transferred to the IDE while others are not. The most recent example I experienced was that changes to the ARR and Prescaler registers of the TIMER module were transferred to the IDE, but the changes to the PWM (CCR1) register remained the same. In this case, I had to manually change the relevant value in main.c (and it was quite difficult to notice).Look, the main problem here is that we developers ultimately trust ST
