Hi, is anybody able to confirm if the STM32H563ZIT3Q has an ethernet peripheral? Thanks, regards. 

Hi everyone, I’m building an open-source desktop IDE for microcontroller learning and prototyping, mainly focused on Arduino and STM32. The goal is not to replace professional tools like STM32CubeIDE, PlatformIO, Keil or IAR, but to provide a simpler learning-oriented workflow for students, technicians and training centers. Current / planned features: Arduino and STM32 project creation Build / upload workflow Serial monitor and serial plotter STM32 debug with GDB/OpenOCD Register / memory / stack views Basic SVD peripheral view Static analysis with cppcheck / MISRA-light Coverage reports Crash / HardFault reporting Power profiling demo via UART/SWO-style events QEMU/Renode simulation experiments I’m looking for honest feedback: Would such a tool be useful for education or training? Which feature would be most valuable?

I'm using an STM32H7S78-DK board and I have a part of the firmware that, from the boot, updates the FLASH from a .bin inside an SD cardThe code is pretty simple as I loop the FLASH comparing every sector with the one in the SD card and, if different I erase the internal flash sector and write the new one.Everything was working correctly until a update the code via CubeMXThe read seems to still workingif (EXTMEM_Read(0, fw_offset, flash_buf, br) != 0)but as soon as I do theif (EXTMEM_EraseSector(0, fw_offset, FLASH_SECTOR_SIZE) != 0)I got an errorThe crash happens in if (EXTMEM_DRIVER_NOR_SFDP_OK != EXTMEM_DRIVER_NOR_SFDP_SectorErase(&extmem_list_config[MemId].NorSfdpObject, local_address, sector_type)) { retr = EXTMEM_ERROR_DRIVER; }I've rolled back jus

Hello,long time lurker, now with an issue that I would like to solve. I developed a firmware that runs standalone without issue. I would like to use the secure manager on my STM32H573VI microcontroller.I followed the procedures at this link: https://wiki.st.com/stm32mcu/wiki/Security:How_to_make_your_application_compatible_with_Secure_Manager  and I am able to run the python provisioning.py --sfi-flash command. Then from the cube ide I can debug my program that is written with cmake and the cubemx template.Since I am using threadx I set TIM6 as a time base for the HAL.What I observe is the following...- if I run the application straight away, I do not see the tick increment. - I set an __enable_interrupt() before HAL_Init() and I see that

So I have a series of PIN configured as Application and/or Boot only but, for some reason, the CubeMX generates the code on both main.h in Appli and Booti.e.I have PC0 set as Application only context but I found it in the Boot as well 

I've been struggling with a strange ADC problem for a while, and have now made some interesting observations.The scenarioI'm using an STM32G474, where HRTIM directly controls a peltier driver for temperature regulation. Temperatures are measured by ADC4 (12 bit resolution), running in DMA circular mode, triggered by TIM7, at 1 kHz. This works. Temperatures are coming in, and are being used for PID regulation.The problemQuite often – perhaps always – some of the temperature readings are being disturbed, but only at certain temperatures. At first, I thought that it was random noise, but in a graph the noise looks strange. Not random at all.After monitoring the raw ADC values that the DMA has thrown into memory, I discovered something that might be a clue – or it might just be a source of confusion. Every time a noisy sequence occurs, the ADC readout jumps to a lower nearby value where the five least significant bits

Hello!

Hi,I am going to use PSSI interface to communicate with FPGA (unidirectional interface from FPGA to MPU). Is there some kernel driver example for PSSI available? Thanks!Alexey.

As in attached image, the build hammer icon is greyed out after importing project made in STM32CubeMX version -- 6.17.0 to CubeIDE version -- 2.1.1.I have selected tool chain as STM32CubeIDE in the Project Manager in CubeMX and after generating the code, i tried by opening the project from CubeMX as well as importing project to CubeIDE.MCU : STM32G474 series. Thanks for the help in advance.

Hi,I have a DMA2D issue with a STM32N6 Nucleo-144 board. I can use the DMA2D to blend two framebuffers if the inputs are in the AXISRAM1. However, when one of the framebuffers is in AXISRAM3 (NPU RAM), the DMA2D doesn't copy from the relevant framebuffer. There is no error, but the output is invalid.I can copy to the AXISRAM3 using HPDMA without any issue. I have configured the RISAF4/5/6; otherwise, I am unable to copy to AXISRAM3. This is the code to configure RISAF4/5/6 (NPU RAMs): __HAL_RCC_RISAF_CLK_ENABLE(); RISAF4->REG[0].CFGR = 0x00000000; RISAF4->REG[1].CFGR = 0x00000000; RISAF4->REG[0].CIDCFGR = 0x000F000F; /* RW for everyone */ RISAF4->REG[0].ENDR = 0xFFFFFFFF; /* all-encompassing */ RISAF4->REG[0].CFGR = 0x00000101; /* enabled, secure, unprivileged for everyone */ RISAF4->REG[1].CIDCFGR = 0x00FF00FF; /* RW for everyone */ RISAF4->REG[1].ENDR = 0xFFFFFFFF; /* all-

Hello, I am using a B-G431-ESC1 board to power some BLDC motors. I have alrady used it succesfully to spin some 2 pole pairs BLDC using Hall sensors for speed control. I even managed to implement some code to stop the motor at every half rotation of the shaft. It worked flawlessly with this type of motor. Now, I tried connecting a different type of BLDC, still 2 pole pairs but thats all I know since I don't have the datasheet. The motor profiling part went as expected and it managed to calculate all the relevant properties of the motor. I saved it and implemented the Hall sensors as aux speed control for Hall profiling. The difference from the other type of motor is that this one has a 6-wire Hall connection. Using an oscilloscope, I found that the extra cable was likely for temperature, so I left it unconnected. However, I keep getting Pin not connected on the pin wher the same cable is plugged (the blue cable). Whether I put the blue cable on H1, H2 or H3, the board doesnt recogni

Hi, On STM32F746G-DISCO board I have a problem with USART1 (ST-Link VCP): - TX (PA9) works fine – I can send messages- RX (PB7) doesn't receive any characters and I think the board is not waiting for commands Tested both polling (HAL_UART_Receive) and interrupt mode (HAL_UART_Receive_IT). Pins are configured correctly. Did anyone have similar issue on this board? Any ideas what can block RX? Thanks! /* USER CODE BEGIN 2 */ HAL_UART_Transmit(&huart1, (uint8_t*)"Connected\r\n", 11, 100); HAL_Delay(100); HAL_UART_Receive_IT(&huart1, &rxByte, 1); /* USER CODE END 2 *//* USER CODE BEGIN 4 */ void ProcessCommand(char *cmd); void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart) { if (huart->Instance == USART1) { if (rxByte == '\n' || rxByte == '\r') { if (rxIndex > 0) { rxBuffer[rxIndex] = '\0'; // zakończe

I have been working on porting a custom board using the STM32MP255F-AK.I performed the following tasks:- Used STMCubeMX to configure pins and other settings- Manually added the custom board-specific sections to the DeviceTree- Added the DeviceTree to the Distribution Package's meta-st/meta-stm32mp-addons/mx directory- Created a custom board configuration file and performed the build- Wrote the resulting TF-A and FIP images to an SD card and booted the system- Before performing this work, I verified the operation of STOpenLinux, which was created by modifying the STM32MP257F-DK Device TreeThe TF-A boots, but just before U-Boot starts, a register dump occurs repeatedly and the system stops progressingJudging by the error details, it appears to be a security-related error.Based on the address where the error occurred and the error ID,I tried making various changes to the .ioc and DT files, but the issue persiste

 Hi,I am working with the OEMiRoT reference project (STM32U385) and I need to configure a single Secure application image without TrustZone isolation (S-only application), while still keeping the Secure Data Image enabled.From flash_layout.h, I see the following:  #define MCUBOOT_APP_IMAGE_NUMBER 1#define FLASH_NS_PARTITION_SIZE (0x32000) /* default case */and also this condition:

Hi all,What is the recommended way to not crush our repository and dynamically pull/generate the project's Drivers and Middleware folders?  For instance, our repository has both Bootloader + Application code projects in a repo (and other MCU projects/layouts for the same board).Is there something similar to Platform.IO (or C#'s NuGet packages) where the platform maintains those 3rd-party files in a volatile location and pulls them if they don't exist on your machine? Especially for the sake of not checking into the repo duplication of +15 MB worth of files for each project.Please excuse me if this was already asked. I didn't quite find a solid answer.I'm ok with making a command line script that auto-pulls them too, if that's a possibility.

Are there plans to update CubeMX to support MacOS 27 and later? I have just installed 6.17.0 under MacOS 26 and I get a warning to say the installer will not work with later versions:This is because support for the Intel translation layer will be removed (M series Macs are now into their 5th year).Note the CubeMX app itself does not get this - just the installer.

I’m setting up a new project in STM32CubeMX for an STM32L073RZ using the internal LCD controller in 1/3 bias mode.According to the STM32L0 reference manual (RM0367), the LCD voltage rails should be configured as:PB12 - VLCDrail1PB2 - VLCDrail2 However, in STM32CubeMX, the GPIO configuration only allows:PB12 - VLCDrail2PB2 - VLCDrail2
