Hello, I am trying to connect to the STM32F072C8T6 microcontroller via USB in the STM32CubeProgrammer, however I am getting:"Device is under read out protection ! If you want to disable RDP please reconnect with Read Unprotect enabled"So, when I check the Read Unprotect (MCU) checkbox, I get:"Please Power off Power on your device."After turning the power off/on, I see the same messages. I cannot connect to the MCU via USB in the STM32CubeProgrammer.I have tried different versions of STM32CubeProgrammer:v2.16.0v2.15.0v.2.13.0v.2.10.0v.2.8.0Moreover I tried on second computer with Windows 11 and I have the same issue.I'm trying to connect my custom board, but I also checked another hardware board (BluePill ) with the same STM32F072C8T6 MCU and it doesn't work either.Interestingly, using the DFU-util v0.8 program I can connect to the MCU and successfully read/write memory:  

Hi,I'm getting info on playing mp3 files with my custom Nucleo-U5A9 (originally a NUcleo-U575, I replaced the MCU and added xtal). I'll be using the audio codec TLV320AIC3110 with I2C and SAI from the U5A9. I'll be using ThreadX, FileX an a uSD card. The mp3 files would be in the uSD.I read here about X-CUBE-AUDIO. But the decode spirit mp3 libraries seem to be for the core M3, M4 and M7. Will any of these work with the U5A9 (core M33)? If not, what other options are there?Thanks

Both 'U5 ADCs contain the LFTRIG bit; however, I could not find in either 'U5 datasheet the Tidle value above which this bit has to be switched on.JW 

I'm using the STM32G474 at 170MHz. Is it possible to simulate hadc1.Init.ClockPrescaler = ADC_CLOCK_ASYNC_DIV512; since the G474  only recognizes up to ADC_CLOCK_ASYNC_DIV256; I need very slow readings from the ADC. Thank you Valter

We have 2 nos of STEVAL Drone 02. 1)We assembled correctly the motors CW & CCW 2) Propellers are also correctly assembled. We are using STBLE Drone androidapp. We are facing same problem for both the units.Propellers rotates in proper direction  but its not lifting up.instead it lifts slightly 25 cm above ground & then starts rotating around itself & moves horizontally uncontrolled. Then we have to stop it.VIDEO of Drone behaviour attached.Please suggest RegardsShirish 

I am unable to inspect the device registers for my STM32U545 project. I can see the Cortex core Registers, and see them update as I step through the initialization.The tooltip mentions an svd file, how can I check if it's set up correctly?

Hi,How do I generate a project for STM32CubeIDE using STM32cubeMX2? Apparently, the only options are cmake, IAR, and open-cmsis (Keil). And is it possible to open examples from STM32CubeC5 using STM32CubeIDE?Ari

How is the best configuration for setting MTF as free-running timer ?void MFT_Configuration() { MFT_InitType timer_init; NVIC_InitType NVIC_InitStructure; SysCtrl_PeripheralClockCmd(CLOCK_PERIPH_MTFX1, ENABLE); /* Init MFT1 in mode 2 */ timer_init.MFT_Clock1 = MFT_PRESCALED_CLK; timer_init.MFT_Clock2 = MFT_NO_CLK; timer_init.MFT_Mode = MFT_MODE_2; timer_init.MFT_CRA = 0xFFFF; timer_init.MFT_CRB = 0xFFFF; /* If a square waveform is @ input with a frequency of 10kHz => T = 100 us * * with Prescaler = 16 - 1; => 1us sampling period * the counter number within a period is 100. * * with Prescaler = 1 - 1; => 62.5ns sampling period * the counter number within a period is 16000. More resolution. */ timer_init.MFT_Prescaler = 1-1; MFT_Init(MFT1, &timer_init); /* Set the TnCNT1 at the max value. No matter about the TnCNT2 since it is not used. */ MFT_SetCounter(MFT1, 0xFFFF, 0xFFFF); /* Enable MFT irq */ NVIC_InitStructure.NVIC_IRQChannel = MFT1A

Hi,I'm using two STM32WLE5 LoRa as TX and RX and added AES-ECB Encryption with Hardware Accelerator in the TX side and receive and decrypt it in RX side with the same Key. Now I want to change the TX module and want to implement same logic of AES Encryption in the TX side. Is there any documentation on how that can be implemented in the C/Python code for sending the same data with different module? I have used PyCryptodome Python library for sending the data with encryption but it didn't work as expected. So, Is there any other library or documentation for implementing Encryption by which Receiver can be able to decrypt as before?Configuration of AES in Both TX and RX sidesAny insights or guidance would be greatly appreciated.Thanks in Advance. 

Hello,I recently purchased the STEVAL-IDP004V2 board, and I'm encountering an issue when connecting it with the GUI V2 ST and the TE Concept IO-Link application. The same error repeatedly appears: "master application 6148 Appears and Disappears."Could anyone provide guidance on how to resolve this issue?Thank you in advance for your help.   

Hello,I'm working on the STM32H735G-DK and try to change LTDC pixel format mode on the fly, but it doesn't work. I'm using the BSP example from example board pack in CubeMX for this board. After reset is possible setup the first time pixel format, but whatever I did after it never work. I tried even did full deinit with HAL_Deinit(), but it simply doesn't work. Pckage version is STM32Cube_FW_H7_V1.12.1For example this functionality (changing LTDC pixel format) working without any problem on the STM32U5G9J-DK2. The main() function where I tried doing this looks like:int main(void) { MPU_Config(); CPU_CACHE_Enable(); HAL_Init(); /* Configure the system clock to 520 MHz */ SystemClock_Config() HAL_RCC_MCOConfig(RCC_MCO1, RCC_MCO1SOURCE_HSE, RCC_MCODIV_1); BSP_LED_Init(LED1); /*##-1- Initialize the LCD #################################################*/ /* Initialize the LCD */ //BSP_LCD_Init(0, LCD_ORIENTATION_LANDSCAPE); BSP_LCD_InitEx(0, 1, LCD_PIXEL_FOR

Hi  I am using an STM32N6570-DK board. For my project, I need to measure the total MCU power consumption (core power plus the power consumed by the I/O pins while interfacing with the SDRAM and OSPI flash). I have reviewed the documentation regarding power measurement, but I am confused because there are multiple power supplies. Which pins on CN2 should I use for my measurements, and is there a common point to measure the total power?How to measure power on the STM32N6 - STMicroelectronics Community

Hello,I am using STM32U575RGT6 with CubeMX 6.17 and the bundled X-CUBE-FREERTOS v1.4.0. After enabling USE_TICKLESS_IDLE, I observed that the tick period becomes inaccurate.Specifically, the delay appears to be consistently shortened to about 0.875× of the expected value.void StartDefaultTask(void const *argument) { while (1) { HAL_GPIO_TogglePin(LED_RED_GPIO_Port, LED_RED_Pin); vTaskDelay(400); } }With USE_TICKLESS_IDLE disabled, the delay is approximately 400 ms as expected.After enabling it, the delay is reduced to about 350 ms.I have created a minimal project to reproduce the issue, and it shows the same behavior consistently. The project is attached.Could anyone help explain the cause or suggest a fix?Thank you.

Hi,I’m working with the STM32H7S7L86H and using the SAES peripheral to encrypt and decrypt data stored in an SPI flash.I currently have the peripheral working correctly using HAL functions in polling mode. I also managed to get it working with interrupt mode, including proper input/output callbacks.However, I would like to use DMA to offload the CPU, but I haven’t been able to find any HAL-based examples for SAES with DMA. When I try to use DMA, the transfer does not seem to complete and no callback is triggered.Could you help me understand how to properly configure SAES with DMA using HAL, or point me to a working example?void HAL_CRYP_MspInit(CRYP_HandleTypeDef* hcryp) { if(hcryp->Instance==SAES) { /* USER CODE BEGIN SAES_MspInit 0 */ /* USER CODE END SAES_MspInit 0 */ /* Peripheral clock enable */ __HAL_RCC_SAES_CLK_ENABLE(); /* SAES DMA Init */ /* GPDMA1_REQUEST_SAES_OUT Init */ handle_GPDMA1_Channel13.Instance = GPDMA1_Channel13; handle_GPDMA1_Channel13.Init.Request

I am using STM32h743XIH6 MCU with qspi flash MT25QL512ABB8ESF-0SIT same as STM32H743I-EVAL. when i try to load data to qspi flash using STM32CubeProgrammer and loader MT25TL01G_STM32H743I-EVAL.stldr provided by ST, data read/write working without any on eval board. But when i try the same in my custom board with same configuration it is not working. In my custom board if I erase and read flash content i am getting data as shown in QspiFlashMemoryErase.pngWhen i write data and read it back, i am getting data as shown in QspiFlashMemoryDataWrite.pngData is being written correctly on every even bytes, but all odd number bytes are wrong and always showing as 0x99I have chechked all signals on scope, all signals are coming.i have replaced the flash IC, just to confirm IC functionality, but still not working.

Downloaded the update of STM32CubeMX 6.17.0 to install the ARM version on my M4 MacBook Air with macOS Tahoe.  The issue is that it installs an Intel version and not an ARM version.  I uninstalled version 6.16 before installing this updated version.The installer file was SetupSTM32CubeMX-6.17.0-Mac-ARM.app.tar downloaded from the STM32CubeMX download page.The next macOS version after Tahoe will not support Intel apps and was expecting an Apple Silicon version as per the download!What is up with this?

Hi,I am working on a custom Battery Management System (BMS) using STM32L476RG as the MCU, interfacing with an external battery monitor AFE (BQ79656‑Q1).I first validated the MCU hardware and basic firmware by testing the on‑board LEDs and UART communication via test points using USART2. These tests were successful and confirmed that the STM32 configuration and standard UART peripheral are working as expected.After this initial validation, I started implementing the communication between the STM32 and the AFE. For this communication path, LPUART1 is used, while USART2 remains dedicated only for basic UART testing and debug output.As part of this implementation, I took a Single Device Read command frame from a reference software design document for a similar AFE and directly programmed the frame transmission in STM32CubeIDE using HAL UART APIs.While debugging the firmware in STM32CubeIDE, I consistently encounter a “Target not available” issue during execution, particularly when reaching

Dear Community, I am researching how to use a 50Mpx MIPI CSI-2 2 LANE RAW 10 sensor with stm32N647.The idea is not to use the full sensor, instead using analogue/digital crop and windowing on the sensor to capture a specific part of the image and downsize it to a smaller size before entering the ISP of the MCU. The sensor doesn't have scaling.So after all steps I am left with a frame size that varies from 11.4 to 2.4 Mpx depending on cases.From there the image needs to be downsized to a buffer with a maximum size of 1024x768 px for the display.The question is whether the scaling of the ISP of the STM32N647 can handle downsizing and at what cost. The ISP is rated at 5Mpx 30fps but specifies it is possible above, the datasheet is vague about this.Thanks for the help.

Not the issue of debug probe, just change 'Reset behaviour' to 'None' could solve this.

Section 5.1.1 Step 3 says that Copy the dts file from the directory: x-linux-gnss1-app\linux-kernel\patch\5.15\kernel to the kernelsource directory at <KERNEL SOURCE PATH>/ arch/arm/boot/dts/But in the latest X-LINUX-GNSS1 package, the linux kernel is 6.1.11 and there are 3 patch files and 1 fragment file is present. It is unclear what to copy exactly. @Saurabh.Rawat 

Hello.I created a project for the STM32F769I-DISCO board using CubeMX.I am trying to follow an LVGL example, but the example uses BSP-based libraries, and they are not working in my project. After checking, I found that there is no BSP included anywhere in the generated project.From what I understand, when selecting a board in CubeMX, the BSP should normally be included automatically. However, in my case, it is not.I tried downloading the STM32F769I-DISCO BSP from GitHub and manually copying it into the Drivers folder. However, this caused many build errors, possibly due to missing dependencies or incomplete integration, so I reverted those changes.Could you please advise how to properly include or enable BSP for this board when using CubeMX?Thank you.
