Using STM32CubeProgrammer V2.11.0 on Windows 10I have issues erasing sectors past 127 on the STM32L496RET6 MCU.Erasing sectors 0-127 appears to work okay.Erasing sectors 128-255 does not show an error, however when I re-connect the programmer to the MCU the data is still shown in flash.My option bytes are set as:WRP1A_STRT = 0x10WRP1A_END = 0x17WRP1B_STRT = 0xffWRP1B_END = 0x0

Hi,Float type variable is not working in stm32cube_ide.float r = 3.14;when I debug the value of r it shows 3 and also I cross verify by using if condition.if(r==3.14)but condition fails, that means float variable not working in ide.Please help!

This morning, I installed cubemx and created a project for STM32F767IGT6 using J-link v2 to download the hex file to the board, but it didn't work. The project have included the LTDC, but I cannot get any signal(DCLK/VSYNC/HSYNC) from the test pads on PCB. It looks like the system clock(216MHz) doesn't work orsomething wrong. The board is good and works fine with my the other project hex files.

Hello dear,I will use "STM32H735RGV6" with an external crystal. In the datasheet, it is stated that "External oscillators: 4-50 MHz HSE". However, in CubeIde I cannot assign 50MHz since it is limited to 48MHz. Could you help with this issue?

I have trouble reading from 17th channel of STM32G0B1 MCU, which is PC4 pin.I have to read from channel 0 and 17. If I configure ADC for single channel it reads fine from Ch0, but cannot read from Ch17 (I got value from Ch0 instead). If I configure it to read from Ch0 and Ch17 using DMA, values in DMA array are not changing at all.I share cube-generated MX_ADC1_Init belowstatic void MX_ADC1_Init(void) {   /* USER CODE BEGIN ADC1_Init 0 */   /* USER CODE END ADC1_Init 0 */   ADC_ChannelConfTypeDef sConfig = {0};   /* USER CODE BEGIN ADC1_Init 1 */   /* USER CODE END ADC1_Init 1 */   /** Configure the global features of the ADC (Clock, Resolution, Data Alignment and number of conversion) */ hadc1.Instance = ADC1; hadc1.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV2; hadc1.Init.Resolution = ADC_RESOLUTION_12B; hadc1.Init.DataAlign = ADC_DATAALIGN_RIGHT; hadc1.Init.ScanConvMode = ADC_SCAN_SEQ_FIXED; hadc1.Ini

Id like to write a program to read 2 main frequencies, first one from velocity sensor and second from ignition coil. Both of them to build a car gauge dashboard, (there'll be a few more analog signals to read tough).Given that i come from atmega 328 that has only one input capture module, id like to know if the stm bluepill has the capacity to read both frequencies in the same chip... I'll need to read 2 frequencies, read analog signals, writing steps bits to update gauges and display data in tft 2.4'' module, so im lookinf for advice about selecting the right chipRegardsJulian

Using the STM32Cube with a STM32F4, I set the SYSCLK to 96MhzWhich generates this code RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE|RCC_OSCILLATORTYPE_LSE; RCC_OscInitStruct.HSEState = RCC_HSE_BYPASS; RCC_OscInitStruct.LSEState = RCC_LSE_ON; RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON; RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSE; RCC_OscInitStruct.PLL.PLLM = 4; RCC_OscInitStruct.PLL.PLLN = 96; RCC_OscInitStruct.PLL.PLLP = RCC_PLLP_DIV2; RCC_OscInitStruct.PLL.PLLQ = 4;However, if I call HAL_RCC_GetSysClockFreq directly after SystemClock_Config() e.g. SystemClock_Config(); clkF = HAL_RCC_GetSysClockFreq();clkF is 72000000 i.e 72MhzI've checked that HSE_VALUE is correctly defined as 8000000So I made a copy of HAL_RCC_GetSysClockFreq() and added some deb

Hi all -I'm modifying some legacy code written for a WICED device that contains an STM32F2xx. The original programmer had a passage that reduces down to:#define OB_RDP_Level_0 ((uint8_t)0xAA) #define OB_RDP_Level_1 ((uint8_t)0x55)   FLASH_OB_Unlock(); FLASH_OB_RDPConfig( OB_RDP_Level_1 ); FLASH_OB_Launch(); FLASH_OB_Lock(); NVIC_SystemReset( );I have no idea where he got the value "55" but the upshot is I can't reset my OBs. When I try, I get this output from the programmer software: 15:15:33 : Option byte command : -ob RDP=170 15:15:33 : PROGRAMMING OPTION BYTES AREA ... 15:15:33 : Bank : 0x00 15:15:33 : Address : 0x40023c14 15:15:33 : Size : 12 Bytes 15:15:52 : UPLOADING OPTION BYTES DATA ... 15:15:52 : Bank : 0x00 15:15:52 : Address : 0x40023c14 15:15:52 : Size : 12 Bytes 15:15:52 : Error: Uploading Option Bytes bank: 0 failed 15:15:52 : Error: Reloading Option Bytes Data failed 15:15:52 : Time el

I am trying to create a C# application within Visual Studio 2019 for using STM32CubeProgrammer API because I will need to modify an existing C# application to use it. At the moment I am having trouble connecting to the small board I am using:      int connectionResult = CubeProgrammerApi.Connect(cbUsbIndexes.SelectedItem.ToString());      CubeProgrammerApi.Disconnect();With both of these routines I am getting 0xC0000005: Access violation executing location 0x0000000000000000 errors.I do seem to have gotten the getDfuDeviceList working:      _deviceInfo = AddressOf(ref _dfuDeviceInfo);      _numberOfDfUDevices = CubeProgrammerApi.GetDfuDeviceList(ref _deviceInfo);The DLL Imports I have defined are as follows:    [DllImport(DllPath, EntryPoint = "getD

STM32CubeIDE can update fine, but STM32CubeMX cannot.No, it is not a typo in the title. 

After attempting to code it up myself and after it didn't work attempted to verify using CubeMX.I have 2 questions:CubeMX does not give me the ability to select Alternate Function 2 on GPIOB pin 1 as input for TIM3_CH4, while Datasheet - STM32H750VB STM32H750ZB STM32H750IB STM32H750XB - 32-bit Arm® Cortex®-M7 480MHz MCUs, 128 Kbyte Flash, 1 Mbyte RAM, 46 com. and analog interfaces, crypto States PORTB alternate function does connect to TIM3_CH4 for AF2. Is this correct should TIM3 be able to do capture compare off PORTB_PIN1, or did I miss something?After doing HAL_TIM_IC_Start_DMA, I see the DMA copy TIM3->CCR4 to the destination (in memory) continuously even before any edge input comes in on PORTB_PIN1. Is additional synchronization needed or should this work as I expect

Hello!We have 2 identical custom PCB using STM32F446RE MCU, we encounter the following issues and we can't find out what is happening.I'll try to explain the best I can such problem, testing boards with simple LED blinking program:while (1) { HAL_GPIO_TogglePin(GPIOA, GPIO_PIN_10); HAL_Delay(500); HAL_GPIO_TogglePin(GPIOA, GPIO_PIN_9); HAL_Delay(500); /* USER CODE END WHILE */   /* USER CODE BEGIN 3 */ }board 1: Program sometimes goes to HardFault with:HCLK Clock = 82 MhzHSI RC = 16 MhzProgram stops at HardFault_Handler with:HCLK Clock >= 83 MhzHSI RC = 16 MhzSame happens with HSE = 16 Mhzboard 2:Program sometimes goes to HardFault with:HCLK Clock = 75 MhzHSI RC = 16 MhzProgram stops at HardFault_Handler with:HCLK Clock >= 76 MhzHSI RC = 16 Mhz

I have this library but I can't add in my project to communicate with the component SGTL5000. Thank you for your advices Regards

In CubeMX v6.6.1 with STM32G0 MCU package 1.6.1, there is no option for I2C2 to select SMBus-two-wire interface. Only I2C and SMBus-Alert-Mode.Is this by design (then why?) or an error in CubeMX?

Hello,I am having trouble applying all the option bytes from STM32CubeProgrammer.I have ported the SBSFU example to use it as a bootloader, I am at the stage where I would test all the security settings by configuring the option bytes externally.From my testing, I am able to set PCROP, WRP, and Secure memory but when I try to set RDP which I think should be configured at the end, It fails.Can someone please tell me the proper sequence of option bytes configuration?Looking forward to a positive responseThanks,Kayas Ahmed

CubeMX version: v6.6.1 MacOSMCU: STM32G0B1CCUxIssue:When selecting PLLQ driven from HSE in USB Clock Mux in CubeMX and choosing LL as RCC driver, the clock source for USB is never actually set in the generated code.This line is missing in the SystemClock_Config function:LL_RCC_SetUSBClockSource(LL_RCC_USB_CLKSOURCE_PLL);When selecting HSI48 as USB clock source, this explicit setter is not necessary for some reason.

In the manual RM0468 for the STM32H730 say that the reg "PWR_D3CR" bits "VOS" has 00: Scale 001: Scale 3 (default)10: Scale 211: Scale 1Also in the code defines in "stm32h7xx_hal_pwr.h"#define PWR_REGULATOR_VOLTAGE_SCALE0 (0U)#define PWR_REGULATOR_VOLTAGE_SCALE1 (PWR_D3CR_VOS_1 | PWR_D3CR_VOS_0)#define PWR_REGULATOR_VOLTAGE_SCALE2 (PWR_D3CR_VOS_1)#define PWR_REGULATOR_VOLTAGE_SCALE3 (PWR_D3CR_VOS_0)But in CubeMX Version "6.6.1" Lib version "1.10.0"Only Scale 0,1,2 is selectebel.

Please if you can give me a good link that show how can I use the HAL layer to write and read from the flash.

This is the sample error that pops up. How can I fix this? I'm very new to this so I'm not very familiar with this error. Hope that someone could help me with this.
