After encountering an issue with a Hyperbus flash chip we moved our flash to what we thought would be a simpler OctoSpi Nor Flash. I am working with an STM32H7S7 chip with a NOR Flash S28HS512T. I cannot get the chip to communicate in the desired mode. Here are my steps so far:Configuration code from CubeMX:/* XSPI1 parameter configuration*/ hxspi1.Instance = XSPI1; hxspi1.Init.FifoThresholdByte = 4; hxspi1.Init.MemoryMode = HAL_XSPI_SINGLE_MEM; hxspi1.Init.MemoryType = HAL_XSPI_MEMTYPE_MICRON; hxspi1.Init.MemorySize = HAL_XSPI_SIZE_512MB; hxspi1.Init.ChipSelectHighTimeCycle = 3; hxspi1.Init.FreeRunningClock = HAL_XSPI_FREERUNCLK_DISABLE; hxspi1.Init.ClockMode = HAL_XSPI_CLOCK_MODE_0; hxspi1.Init.WrapSize = HAL_XSPI_WRAP_NOT_SUPPORTED; hxspi1.Init.ClockPrescaler = 3; hxspi1.Init.SampleShifting = HAL_XSPI_SAMPLE_SHIFT_NONE; hxspi1.Init.DelayHoldQuarterCycle = HAL_XSPI_DHQC_ENABLE; hxspi1.Init.ChipSelectBoundary = HAL_XSPI_BONDARYOF_NONE; hxspi1.Init.MaxTran = 0; hxspi1.In

Hello,I want to use the TW9992 NTSC/PAL Video Decoder for STM32N6 to transfer an NTSC camera (720x480 resolution) to the MCU via MIPI-CSI and display it on the screen. I have attached the code below.static void MX_DCMIPP_Init(void) { /* USER CODE BEGIN DCMIPP_Init 0 */ /* USER CODE END DCMIPP_Init 0 */ DCMIPP_CSI_PIPE_ConfTypeDef pCSI_PipeConfig = {0}; DCMIPP_CSI_ConfTypeDef pCSI_Config = {0}; DCMIPP_PipeConfTypeDef pPipeConfig = {0}; /* USER CODE BEGIN DCMIPP_Init 1 */ /* USER CODE END DCMIPP_Init 1 */ hdcmipp.Instance = DCMIPP; if (HAL_DCMIPP_Init(&hdcmipp) != HAL_OK) { Error_Handler(); } /** Pipe 0 Config */ pCSI_PipeConfig.DataTypeMode = DCMIPP_DTMODE_DTIDA; pCSI_PipeConfig.DataTypeIDA = DCMIPP_DT_RGB565; pCSI_PipeConfig.DataTypeIDB = DCMIPP_DT_RGB565; if (HAL_DCMIPP_CSI_PIPE_SetConfig(&hdcmipp, DCMIPP_PIPE0, &pCSI_PipeConfig) != HAL_OK) { Error_Handler(); } pCSI_Config.PHYBitrate = DCMIPP_CSI_PHY_BT_1600; pCSI_Config.DataLaneMapping =

I'm trying to download Cube MX, Cube Programmer, and Cube IDE. I registered and activated the license, but it won't download. I've tried using different browsers (Chrome, Firefox, Edge) without extensions. I accept the License Agreement, but nothing happens. I tried it as a guest user, too, but it won't download. I really need the programs, what should I do?

I am currently working on the LoRaWAN_END_NODE example project for a stm32WL . And I want to receive external data via uart and use the LoRaWan process continually, however I am getting problems. The UART is giving invalid data after the sequencer is being initialized.Edit: I have tried the suggestions below, I have put the gps into a task for the sequencer to run. I have also disabled low power mode. I still get invalid data from the UART that I don't receive when the sequencer is not on.Is this a clock issue? Any ideas?

Hi,I created a blank project for STM32U5G9J-DK2 and in process of programming the board, GfxDesigner generates 400MB file intflash.elf. With GfxDesigner 4.24.1 it is 4MB.Why 4.26.1 generates  intflash.elf so large ? A bug ?Thanks  

***Update***This issue is solved and was due to improper wifi firmware upgrade. Topic can be closed.   Hi STM Team, I have been having issues for the last week with connecting to the STWIN.box via wifi from both iphones and android phones for DATALOG2 v3.2.0. (And to some extent v3.1.0). The configuration of the wifi network does not work correctly when I attempt to send it from the app. The only way I could get it to work, is when I used the Python SDK with firmware version 3.1.0. I was able then to connect with FileZilla and view/download files.Please advise what the possible workarounds are with this issue as I need to use this sensor by connecting to it via wifi and downloading the data files via FTP server.The following is an AI-generated overview of the issue in more detail: Device: STEVAL-STWINBX1 (STM32U585AI) Firmware tested: FP-SNS-DATALOG2 v3.1.0 and v3.2.0 WiFi module: EMW3080 (firmware successfully upgraded per README instructions) App tested: ST B

I have a simple question. Is it possible to use TouchGFX+ThreadX with enabled Ethernet and NETXDuo SNTP client at a same time in STM32N6570-DK board? In other words: take the TouchGFX ClockExample then in CUBEMX enable the Ethernet port with NETXDuo-SNTP server. Will it cause pin conflict? I mean the Ethernet uses the same pins as LTDC. I enabled the Ethernet in ClockExample project and I got blank screen and the app was frozen. After removing Ethernet from the project, the analog and digital clocks appeared again on the display. Thanks, Louis

Good day,I am writing firmware for a custom board using the STM32G0B1KET6 and am experiencing issues related to writing a serial number to the internal flash.As far as I can tell, this MCU has 512 KB of flash split into 2 banks of 128 pages (each page is 2 KB). I am attempting to write to the last page of the first bank (Page 127 @ 0x803F800).I have modified the linker file to reduce the flash area used by my application code like so:MEMORY { RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 144K FLASH (rx) : ORIGIN = 0x8000000, LENGTH = 64K }Here is my flash writing function. uint8_t Flash_Write(uint32_t startAddress, uint64_t data) { __HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_OPTVERR); __HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_BSY1); __HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_BSY2); __HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_PGSERR); __HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_PGAERR); __HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_CFGBSY); if(__HAL_FLASH_GET_FLAG(FLASH_FLAG_CFGBSY) == 1) { return 0; } HAL_StatusTypeDef status;

Hi,We are looking for recommendations on a suitable topology and charge controller for charging a LiFePO₄ battery with the following requirements:Input voltage: 9–36 VDCOutput voltage: 10–36 VDCOutput current: up to 80 AWe understand that a single IC may not support this current level, so we are considering a parallel architecture using multiple controllers. Kindly suggest an appropriate approach and suitable IC options.Thanks,BK

hello ST Community,where can I set it to avoid generating the file "startup_stm32l5...zetxq.s" during compilation and debugging in the stm32CubeIDE environment and also how to avoid that the space bar "|" when editing the line of code of 'main.c' is automatically moved to the last line of code of 'main.c' during compilation and debugging. Where should I set it to avoid all this?Thanks so much for your support

Im trying to setup FreeRTOS with the new STM32N6.According to https://github.com/STMicroelectronics/x-cube-freertos, the new Nucleo board for the STM32N6 is mentioned as supported.But in the CubeIDE, when trying to enable the FreeRTOS middleware, it says that the new nucleo board is not supported. And the docs also only mention AzureRTOS as supported.Is FreeRTOS supported through the CubeIDE? Or only AzureRTOS? 

Hello,I recently came across an ST article describing a Condition-Based Monitoring architecture using a dual-MCU approach, with an STM32L476RG handling signal processing (and potentially edge AI), and an STM32WL dedicated to network connectivity.I find this architecture very interesting and relevant for a project I’m currently exploring, but I would like to better understand what level of support and resources are available from ST for implementing such a solution in practice.In particular, I have a few questions:Does ST provide official support or reference designs for this kind of dual-MCU architecture (STM32L4 + STM32WL)?Are there any example projects, application notes, or firmware packages that demonstrate communication between the two MCUs in this context?Regarding FUOTA (Firmware Update Over The Air), are there existing solutions or middleware provided by ST that support this setup, especially with STM32WL acting as the communication node?Are there recommended tools, libraries,

Hi everyone, I am trying to setup DCMIPP Pipe0 to read data from 256x192 pixel sensor by 16 data lines. Seems everything configured and working fine except of transfer data to destination buffer. DCMIPP frame counter is increasing. Pipe0 dump counter is 0x18000 (256x192x2). HAL_DCMIPP_PIPE_Start return HAL_OK. Pipe0 packer memory address register is qual to Pipe0 memory status address register and correspond to address of buffer in RAM. I checked that DCMIPP don't write zero values by initing frame buffer with 0xFF and it wasn't changed to zeros.   I am sure that sensor is working because of frame counter, dump counter, checking lines with oscilloscope and it is working with other pcb with STM32H7 and DCMI interface.   Also I validated that debugger read frame buffer correctly by sending it thought uart.   Source code is simple, generated by cube init than I2C configuration of sensor(validated) and than reading in loop with delay: while (1) { H

Hi Team, I am designing a custom PCB using STM32H753 and planning to use the QUADSPI peripheral for external memory. My use case is data read/write (indirect mode) — not XIP or memory-mapped execution. While working in STM32CubeMX, I came across some configurations that are confusing, and I’d like to clarify the actual hardware behavior. 1. Dual Bank vs Chip Select behavior In CubeMX, I can configure: QuadSPI Mode: Dual Bank with Quad Lines Chip Select options: Enable Chip Select 1 for both banks Enable Chip Select 2 for both banks Enable Chip Select for each bank My understanding: NCS → Bank1 NCS2 → Bank2 Questions: If I select “Enable Chip Select 1 for both banks”, does this mean: Only one physical flash is used and banks are logical partitions? Or is there any way two physical memories are still utilized? What is the exact meaning of “bank” in this context (hardware vs logical)? 2. BK1_IOx and BK2_IOx pins confusion CubeMX exposes: QUADSPI_BK1_IO0

I have recently installed STM32CubeIDE 2.1.1 on linux and opened an existing project workspace. Everything looks fine except the integration with CubeMX for ioc files (which I believe is now by-design). The problem I have is after going to eclipse marketplace and installing Subclipse, it installs fine, then after restarting it goes into an endless loop saying the application is not responding. Finally, I got a message about "Failed to load JavaHL Library.", but I'm not sure if that's the real cause as dismissing the dialog reverts back to the application not responding loop.  Reinstalling the IDE does not help. The only way I've found to get the IDE to work is by removing the stm32 folder under $HOME/.eclipse, but this doesn't correct the issue with subclipse or its connection to subversion. Any help much appreciated.

My device is quite power-sensitive. If I use a single DDR3L module with an STM32MP157 or 135, can I eliminate the need for a VTT power supply?

Hi,I have STM32H755ZIT3 controller, and I am tying to read voltage sensor AMC1333M10 and sensor has internal clock of 10 MHz . I am trying to read on controller DFSDM channel 7, core M4 with clock 64 MHz . Is this practically possible to read in such a configuration ? As when I read the value(dfsdm_buffer), it is always 7 (~0) whether there are voltages on the terminal or not.Code: // start HAL_DFSDM_FilterRegularStart_DMA(&hdfsdm1_filter0, (int32_t *)dfsdm_buffer, BUFFER_SIZE); // callback : void HAL_DFSDM_FilterRegConvCpltCallback(DFSDM_Filter_HandleTypeDef *hdfsdm_filter) { ... }Following is my configuration for DFSDM in MX : Channel 7 : "PDM/SPI input form ch7 and external clock"Channel 7 :Channel 7 Parameters:Type : "SPI with rising edge"Offset : 0Right Bit Shift : 0x00Analog watchdog parameters:Filter Order: "Sinc 3 filter type"Oversampling: 1Filter 0:regular channel selection:regular channel selection: "Channel 7"Continuous Mode: "Continuous Mode"Trigg

Hello,I'm trying to implement the Key Establishment workflow on my hardware based on STM32U5 MCU and STSAFE-A110 secure chip. The ephemeral key pair generation (StSafeA_GenerateKeyPair) works fine and the establishing key (StSafeA_EstablishKey) with the ephemeral private key and the remote host public key gives me a 48-byte shared secret by using NIST P-256 as curve ID.In the ST library provided, it is mentioned that the StSafeA_EstablishKey function provides a shared secret. In cryptography, a key agreement should return a shared secret on 32 bytes for NIST P-256 curve ID and then this shared secret may be used to compute a 48-byte shared key using HKDF with SHA-256 for example by providing salt and info.So what does exactly return the StSafeA_EstablishKey function of library? A shared secret or a shared key?Remote-side (Linux-OS computer), if I compute a key agreement using the remote private key and the STSAFE ephemeral public key, I get a 32-bytes shared secret (with

Hello, We are looking for suitable drivers for L9396. Got only the Datasheet & a WSS Operation document. Can you help with the SPI Driver ?   Regards, Prakash B J

I am using ST’s Motor Control Workbench (MCW) version 6.3.2 to control a sliding door. I am using PMSM as motor and FOC as control method. PMSM has 10 pole pairs and there is a 1024 ppr incremental quadrature encoder on it (has not index pin). I am using Nucleo-G474RE, STEVAL-IHM023V3 and X-Nucleo-IHM09M2 boards. I am having trouble with encoder alignment. if I'm not mistaken, ST MCW uses “move till aligned with phase A” method (see attachment) as the encoder alignment. But i have a mechanical limit and this will not allow the motor to perform the needed alignment movements. I have posted this in the motor control forum. Not answered yet (https://community.st.com/t5/stm32-mcus-motor-control/incremental-encoder-alignment-problem/td-p/775343) Does ST have any plans to update MCW software to include the motionless start method into speed sensing configuration in the near future? Can anyboady give/share source code/flow chart etc.? Any information you provide will be gl

Hi,I am working with the STM32N6 series MCU on the STM32N6570-DK board and have encountered a pin multiplexing conflict.As per the schematics and datasheet:PA15 (JTDI) and PB4 (JNRST) are multiplexed with LTDC signalsThese pins do not appear to have alternate mappingsMy use case requires:LTDC for driving the displayJTAG for debugging (full JTAG, not just SWD)However, enabling LTDC conflicts with the JTAG interface, specifically JTDI.I have a few questions:Is there any supported way to use both LTDC and full JTAG simultaneously on STM32N6?Are there any alternate pin mappings or remap options available that are not obvious from CubeMX?Is dynamic switching (e.g., using JTAG during debug and reconfiguring pins for LTDC at runtime) a viable or recommended approach?Are there any hardware workarounds or recommended debug strategies for this scenario?I understand that switching to SWD avoids this issue, but I would like to confirm if full JTAG usage is fundamentally incompatible with LTDC on t

Hello,I found a CubeMX database issue affecting STM32H747 dual-core projects using FreeRTOS with CMSIS-RTOS V2.EnvironmentMCU: STM32H747Cube/HAL: STM32CubeH7 1.13.xCubeMX: 6.17FreeRTOS: 10.6.2ProblemTwo FreeRTOS configuration parameters are not present in the MicroXplorer Configuration settings and are not retained in the internal IOC model:configUSE_SB_COMPLETED_CALLBACK configUSE_MINI_LIST_ITEMBecause of that, code generation can produce invalid output in FreeRTOSConfig.h such as:#define configUSE_MINI_LIST_ITEM ( valueNotSetted ) #define configUSE_SB_COMPLETED_CALLBACK ( valueNotSetted )This breaks the build and/or downstream FreeRTOS code.Editing the .ioc manually does not solve it permanently, because CubeMX overwrites the .ioc on regeneration.Adding manual defines in USER CODE blocks is only a local workaround and does not fix the root cause.Root cause foundThe issue appears to be in the CubeMX FreeRTOS mode database, not in the generated project itself.For STM32H747, CubeMX uses
