Hi all,I have this demo board. I copied the BSP demo code to my own empty project to understand and learn how the LCD code works. I copied the code from the BSP demo function by function but I moved the code to my files (filenames and project tree folders) so it makes more sense to me. I'm at the point where the demo draws rectangles on the screen and the demo runs. I copied the touch panel stuff but it is disabled because it was getting stuck in the init function. I'll deal with the touch panel later.I can not get the function that draws the rectangles on the LCD to work more than once when I program the board with my project. If I try to debug and step thru the code it actually works. I traced the part where it "hangs" by adding a line to toggle the green LED in the board. The part where it hangs is in the Polling For DMA transfer function: (void)HAL_DMA2D_PollForTransfer(&hlcd_dma2d, 50);BTW I'm new to STM32U5G9J, never used it before. I read the reference manual for the MCU and

Hey, Guys!I’m designing an application to record TDM data source with 48k x 16 slots x 32Bit Format based on STM32MP151.But from the datasheet, there is some confusion.It seems the SAI supports 32bit and 16 slots from the SAI main feature description. But the FRL register is limited to 256, which cannot meet the requirement: 32*16 = 512 > 256.I’m using an external CODEC to generate the TDM clock, so STM32MP151 is in slave mode.Does anyone have experience with an application like this?Thanks!      Jampa.    

Environment & Hardware MCU: STM32F407ZET Test Temperature: -10°C to 5°C Application Context: Internal flash memory is actively used for data storage purposes When the MCU is interrupted specifically during an internal flash write operation (HAL_FLASH_Program)—either by a sudden VDD power-off or a hardware reset (NRST assertion)—it completely fails to boot upon the subsequent power-up or reset release. This issue is highly temperature-dependent and only occurs at low temperatures. If the interruption happens while the flash is idle, or if the board is at room temperature, the MCU reboots perfectly fine. Observed Symptoms & MeasurementsGarbage Vector Fetch: Attaching a debugger via hot-plugging shows that the CPU never reaches main(). Consequently, essential initialization routines like SystemClock_Config() and HAL_Init() are completely bypassed and fail to execute. Instead of fetching the correct reset vector from 0x08000004, the Program Counter is loaded with a garbage addr

Software version: STM32CubeMX2 1.1.1 Target MCU: STM32C542RCT6Steps I followed:Created a new project and generated the CMake‑based IDE project to a target folder. Closed CubeMX2, then manually deleted Core/Src/main.c via file explorer. Opened the original .mx2 project file again, kept using the same output directory, and clicked Generate IDE project.Observed behavior: After code generation finishes, main.c is still missing from the folder. There is no warning message or popup to notify me the main entry‑point file is absent. Consequence: CMake build fails with undefined reference to main.In legacy CubeMX6, when main.c was removed, code‑generation would recreate this template file automatically. This does not happen in CubeMX2 1.1.1.Current workaround: I have to generate project files into a brand‑new empty folder to get a fresh copy of main.c, then copy this file back to my original project directory.Analysis: It seems CubeMX2 treats main.c as a user‑modified file and skips regeneratio

I am really trying to report a problem/bug but I could not find straghtforward way to do it on the STM site. So here it goes:STM32CubexMx for certain object (like USBX) creates virtual folders with spaces in name. These cannot be resolved correctly by STM32CubeIDE (Eclipse) when they are reference links. Project Explore shows folders but with no files and they are not build.For example:UX Device CoreStackUX Device ClassesUX Host Stack The system the tool run under is Windows 11.

Hi!Is there support for enable and view SWO output in the STM32 VScode 3.x.x. extension using ST-LINKV3?For now, this is the only feature that would keep us from moving away from the old eclipse-based platform.If there is no SWO support: Is it on the roadmap?

Heyho,I just found that the STM32L07 has too few DMA channels for my application, so I probably might need to use a DMA channel for two peripherals - surely not at the same time.So when switching the DMA request to another peripheral via DMA1->CSELR, is it enough to disable the DMA channel (DMA1_Channeln->CCR &= ~DMA_CCR_EN (no transfer active)), then set CSELR new? Thanks in advance!

Hello everyone, I have successfully controlled the Lin Engineering BL23E3301D04RO motor with the Nucleo-G474RE and IHM08M1 inverter .. using FOC configured in MC Workbench and the motor’s built-in encoder.I then copied the entire project and changed only the engine.Now I’m having trouble getting the following PMSM motor to run.

Hi,I'm trying to bring up an IMX219 (Raspberry Pi Camera Module v2) on the “x-cube-n6-camera-capture” reference project for nucleo657x0q, I first tried this under Zephyr and got working capture, but only at reduced resolution.  I've since moved to writing a native driver for “stm32-mw-camera” instead, using “imx335.c” “cmw_imx335.c” as a structural reference template but only at the code/flow level since IMX335's actual register map isn't in any public datasheet I could find. For register values, PLL chain, and gain formula I relied entirely on the official Sony IMX219 datasheet instead, since the two sensors don't share a register layout.My questions are:1. Is there any official guidance for integrating a third-party sensor into `stm32-mw-camera` — driver/BSP side?2. Beyond the lane count and PHY bitrate, is there anything else specific to porting from a 4-lane sensor (IMX335) to a 2-lane one (IMX219) that I should watch out for? If writing a custom driver isn't the recommended path h

Device: STM32H7S3L8H6Datasheet DS14359 Rev 6, Table 26 "General operating conditions", gives forfCPU (CPU clock frequency):    VOS low    max 400 MHz    VOS high   max 600 MHz   (8)    footnote (8): "With ECC disabled"We cannot find any stated maximum for fCPU with the AXI-SRAM ECC ENABLED(user option byte ECC_ON_SRAM = 1). RM0477 mentions ECC only in connectionwith AXISRAM4 wait states, not with a frequency limit.This matters to us because ST's own OEMuRoT/BL2 reference code(OEMIROT_USER_SRAM_ECC in boot_hal_cfg.h) requires that option byte andrefuses to boot without it, so an application using the STiRoT + OEMuRoTsecure boot chain necessarily runs with ECC permanently enabled.Operating conditions on our side: VOS high (range 0), LDO supply,TJ <= 105 degC.Questions:1. What is the maximum fCPU for this device with ECC_ON_SRAM = 1?2. In the OEMuRoT reference code, SetSysClock() selects 380 MHz with the   comment "to be functional with all hardware configurations (ECC_ON_SRAM   enable

Hi, Following the original discussion here, this topic is split into a separate issue to remain aligned with Community guidelines and better visibility.DFU mode This processor can program the Option Bytes over DFU DFU ModeThis Processor is totally misdesignedIt exposes the Flash memory 3 timesFor me this looks like a severe bug.If you have a STM32G0B1 with read and write protection there is NO WAY over DFU get rid of these protections.

I am working on an STM32N6 hardware design, and have reviewed both development kit reference designs (MB1939/MB1940). Both designs use the same power supply scheme, when using internal SMPS it has 2x 3V3 regulators and 3x 1V8 regulators.I am interested in combining several power supplies if possible, notably:1. Is it possible to tie all 3V3 together?While AN5967 suggests to apply VDD33USB in the last step of power sequencing, the VDD33USB supply is noted to be independent of the other supplies within the N6, just like the VDDIOx supplies. The reference designs have tied VDDIO4 to VDD at 3.3V, which makes me believe I could also combine VDD33USB and VDD.Aside from just VDD33USB and VDD, all the 3.3V peripherals on the dev kits come from the second 3V3 supply, can I tie all peripheral 3V3 to VDD33USB and VDD, so I have a single 3V3 rail on the PCB?If not what about the STM32N6 disallows this?2. Can I combine 1V8 for peripherals with VDD18AON?Is there anything against connecting

I’m trying to run a fork of the STM32N6-GettingStarted-ObjectDetection project for the STM32N6570-DK on my own board.My board has the same clock configuration, memory interface, and LCD interface as the STM32N6570-DK. However, instead of a CSI camera, I’m using an 8-bit parallel camera interface.The frames come from a custom FPGA source with the following parameters:75 MHz clock at 8 bit width bus YUV422 1280 × 768 30 fps Embedded synchronization ITU656My changes to the original project are:Added GPIO initialization for the 8-bit parallel camera interface. Changed the DCMIPP configuration from CSI to parallel mode:const DCMIPP_EmbeddedSyncCodesTypeDef syncСodes = { .FrameStartCode = 0xAB, /* frame SAV*/ .LineStartCode = 0x80, /* line SAV */ .LineEndCode = 0x9D, /* frame EAV */ .FrameEndCode = 0xB6 /* line EAV */};const DCMIPP_ParallelConfTypeDef pParallelConfig = { .Format = DCMIPP_FORMAT_YUV422, .VSPolarity = DCMIPP_VSPOLARITY_LOW, .HSPolarity = DCMIPP_

I’m using the MB1293 USB dongle as a daughter board for a project & am after the dimension between the 2 edge headers as I need to create a footprint on the main board. Is this information available, I’d rather not trust on manual measurement. See below,  

ST moderator: New question split from this thread: Thanks, that could indeed explain the behavior we are seeing, since we are powering Vdd with 3.3V.Since the application requires a stable ADC reference, I would like to ask whether the STM32L475 provides any internal precision reference that can be selected as the ADC conversion reference.

Hello,I am working with an STM32L475RET and have encountered an unexpected behavior with the ADC reference voltage.My hardware configuration is the following:VDDA and VREF+ are tied together and supplied with a precise 2.5V reference. The ADC is configured for 12-bit conversions. The 2.5V reference has been verified with a multimeter and is stable. ADC clock source is set to 48MHzWhen measuring several analog input voltages, the ADC results consistently do not match the expected values assuming a 2.5V reference. I found that the measured ADC values correspond much more closely to an effective reference voltage of approximately 2.62V rather than 2.5V. To further investigate, I measured the internal VREFINT channel and compared the ADC result against the value expected from the datasheet, and assuming a 2.5V reference, the VREFINT result (1.167V) does not match the expected value:Using this initial config for the ADC:/** * @brief ADC1 Initialization Function * @param None * @retval No

Hi ST Community,We are using the hardware CRC peripheral in our project for CRC computation.During system initialization, we initialize and configure the CRC peripheral ourselves. However, we observed that after calling MX_TouchGFX_PreOSInit(), the CRC peripheral appears to be re-initialized.We would like to understand how TouchGFX uses the CRC peripheral internally.Specifically:Does TouchGFX use the hardware CRC peripheral only during the MX_TouchGFX_PreOSInit() phase? Is the CRC peripheral used by TouchGFX during frame rendering or while processing/displaying frames? Are there any other TouchGFX phases, functions, or background operations where the CRC peripheral may be accessed? If both TouchGFX and our application use the same hardware CRC peripheral, could sharing the peripheral cause any issues?Our concern is that our application relies on a specific CRC configuration, and we want to ensure that TouchGFX does not modify or reconfigure the CRC peripheral after our initialization,

Hey guys i have been using Stm32 Model Zoo repo as a base for my application development . After building a appli i want to dive deep into FSBL and optimize bootup time of stm32n6 . But the model zoo repo comes with pre compiled hex file as FSBL rather than a FSBL project . Is there any way to replace the hex file with a actual FSBL project ? 

Dear ST Support Team / Community Engineers,I am currently integrating the ST25DV04KC into my design. The VCC and LPD pins are connected to an MCU, which controls the transition between normal operation and ultra-low power mode.During testing, I observed an abnormal voltage behavior on the LPD pin:System Voltage: 3.1V Pull-up Resistor: 4.7kΩ (External) Issue: During the level switching transition, the LPD pin voltage stalls at an intermediate level of approximately 2.1V, instead of rising cleanly to VCC. This intermediate voltage persists long enough to potentially cause logic uncertainty for the MCU.Troubleshooting Steps Taken:Reduced Pull-up Resistance: I replaced the 4.7kΩ resistor with a 1.2kΩ resistor. This change successfully eliminated the intermediate voltage plateau, and the signal now transitions correctly. VCC Disconnection Test: I also noticed that disconnecting the VCC supply seems to eliminate this phenomenon as well.My Questions:What is the physical mechanism causing this

Hello everyone, I'd like to use the LevelX API with FreeRTOS on an STM32H5 microcontroller. I know that LevelX is typically used with AzureRTOS, but I'd like to know if ST provides any guidance on integrating it with FreeRTOS or if anyone has any suggestions on how I can do this. Thanks for your help.

Hi!I'm struggling to wrap my head around timers - I am trying to schedule some ADC reads of a current sense amplifier in a motor control setup.I have three center-aligned PWM waveforms being generated by Timer1, which successfully commutate a BLDC motor. That's great. I would now like to schedule an ADC read once per PWM period. A simple first try at this would involve a single read right in the center of the PWM waveform. A slightly swankier version would be to calculate the largest duty cycle of my three PWM phases, and schedule my ADC read just after this point (but, again, just once per PWM period). I have experimented with configuring Timer1's TRGO to "Update Event", and scheduling my injected ADC read to be "Timer 1 Trigger Out Event". This, however, schedules the read at the beginning of the PWM period, rather than in the center of it. I'm also experimenting with setting up a slave timer - the idea being to trigger this secondary timer based on the above Timer1 TR
