STM32 MCUs Products

Hello,STM32F411CE microcontroller.Where can I find, which of command the Erase or Extended Erase command is supported by the UART bootloader?There is a note 4 in the AN3155 (page 7 and,also see Figure 1 below) which says that the Erase (x043) and Extended Erase (0x44) are exclusive. A device can support either the Erase command or the Extended Erase command, but not both.    Figure 1: 

I am trying to run the Secure Boot examples from STM32CubeL5 and have everything built, but on step 2 where I run `TFM_SBSFU_Boot\STM32CubeIDE\regression.sh` I am having an error where I cannot program the option bytes.(Another similar thread was with someone who bought a counterfeit part so I'll also mention that I bought the kit from ST.)This is the script output $ ./regression.sh regression script started Regression to RDP 0, enable tz ------------------------------------------------------------------- STM32CubeProgrammer v2.19.0 ------------------------------------------------------------------- ST-LINK SN : 004600313137510B33333639 ST-LINK FW : V3J13M4 Board : STM32L562E-DK Voltage : 3.29V SWD freq : 8000 KHz Connect mode: Hot Plug Reset mode : Software reset Device ID : 0x472 Revision ID : Rev Z Device name : STM32L5xx Flash size : 512 KBytes (default) Device type : MCU Device CPU : Cortex-M33 BL Versio

Hey everyone,I'm working on a custom board based on the STM32H753 MCU. I successfully programmed it using STM32CubeIDE initially, but ran into an issue when trying to re-flash it — I got the error:"Unable to erase flash memory to reprogram it"To work around this, I connected to the board using STM32CubeProgrammer and performed a full chip erase using the following settings (details below). I clicked Apply, and the flash erase appeared successful. After erasing, I’m no

Here in the below image from the Cube MX it suggests that, SET all the free pins as analog (to optimize the power consumption). How does it help. Also is it applicable to all the controller families?  

Hi, I have a question about this highlighted text in the AN2867 document refering to the "calculating external resistor" paragraph As I understood the condition to use a Rexternal is "if the power disipated in the crystal is higher than the value specified by the crystal manufacturer", as shown above so my question is how to check the power dissipated in the crystal? how to know if I`ll need to use Rext before have a physical implementation of my MCU thanks for your helpOne more extra question (not a technical one) is it normal to feel a little bit overwelmed some times doings this kind of desing? (is my first tim

I have been trying to figure out why I keep getting consistent hard faults when trying to access peripheral instances after waking from Stop Mode 2.  Here is the code I am usingFor entering stop mode:static void SystemClockConfig_STOP(void) { /* A) Ensure V_CORE supports 120 MHz again */ HAL_PWREx_ControlVoltageScaling(PWR_REGULATOR_VOLTAGE_SCALE1_BOOST); /* B) FLASH: raise latency before any SYSCLK jump */ __HAL_FLASH_SET_LATENCY(FLASH_LATENCY_5); while (__HAL_FLASH_GET_LATENCY() != FLASH_LATENCY_5) {} /* C) Handle AHB overshoot if needed */ if ((RCC->CFGR & RCC_CFGR_HPRE) == RCC_SYSCLK_DIV1) { MODIFY_REG(RCC->CFGR, RCC_CFGR_HPRE, RCC_SYSCLK_DIV2); } /* D) Bring HSE & PLL back */ __HAL_RCC_HSE_CONFIG(RCC_HSE_ON); while (!__HAL_RCC_GET_FLAG(RCC_FLAG_HSERDY)) {} __HAL_RCC_PLL_ENABLE(); while (!__HAL_RCC_GET_FLAG(RCC_FLAG_PLLRDY)) {} /* E) Switch to PLL */ MODIFY_REG(RCC->CFGR, RCC_CFGR_

I was comparing the STM32 Debug Support documentation (Chapter 26 in RM0360) with official ARM documentation and noticed something that I cannot explain. The documentation for the SW-AP registers appears to be wrong. It is simply a rewording of the documentation of the SW-DP registers. The IHI0031 document from ARM shows the correct definitions of the SW-AP registers. It however leaves certain fields as implementation defined and I believe this information should be in RM0360. I have checked and the same appears in the RMs for the G030 and the C030. I am interested in knowing, for example, the details of the PROT bit field (Bits 30..24) in the CSW register which should be at address 0x00 in the AP.  

 Hello everyone,I have been working with the STM32L431RCTx on a project where I need to log audio data to an SD card. I have attempted to do multiple things unsuccessfully and would really appreciate your help to see where I am going wrong. I am new to working with SD cards, so I recognise that I may have missed something in my research. For all of the below, I have tested with SDHC and SDXC cards with the same results.First; I have tried to setup the SDMMC interface with at least 20MHz clock speed (clock divide factor 0)The behaviour is very intermittent. It sometimes mounts, opens, writes, closes, then unmounts, but other times will not open or write without an FR_DISK_ERR. My error handling attempts to correct any errors, but I believe there is no fix for a FR_DISK_ERR right? After a while a Hard Fault occurs.I tried again with 40MHz clock speed and clock divide factor of 4. W

Hello, I'm attempting to work with the AD5592 ADC/DAC in SPI mode and am unable to confirm communication. I'm attempting to read and write to single registers to determine whether communication takes place since I don't have an oscilloscope or logic analyzer at the moment. Whenever I try to read any register, even if I try to write to a register first, I receive this same result. I tested the AD5592 with an Arduino Uno in DAC mode and was able to successfully generate outputs on the channels so I'm sure there isn't an issue with the board. However, when I test the AD5592 with both a nucleo and a custom board it doesn't work. I saw a similar post

Hi. I am using STM32H735VG for SPI communication with external ADCs.But I want to add external ADCs and I already used all 5 SPIs.So I will use OCTOSPI, can OCTOSPI play the same role as classic SPI?In menual, OCTOSPI in indirect operating mode works like a classical SPI interface.If they play the same role, how I set the pin?(I will use only one OCTOSPI.) Thank you.

Hi,I want to know pinout to read flash from CHIP stm32F103zet6 using ST-LINK.Can someone provide it, im new on STM32 chip. Thanks.

Hi, I’m trying to configure UART4 on the STM32H753ZIT to work with a USB-TTL converter for data transmission and reception. I can see that the STM32 is sending data, but the TTL converter isn't receiving it. I've attached the code file and the output file.

HICan you tell me how to configure filter to accept only ID 202 to 205 .CAN_FilterTypeDef sFilterConfig; /* USER CODE BEGIN CAN1_Init 2 */ sFilterConfig.FilterBank = 0; sFilterConfig.FilterMode = CAN_FILTERMODE_IDMASK; sFilterConfig.FilterScale = CAN_FILTERSCALE_32BIT; sFilterConfig.FilterIdHigh = 0x0000; sFilterConfig.FilterIdLow = 0x0000; sFilterConfig.FilterMaskIdHigh =0x0000; sFilterConfig.FilterMaskIdLow = 0x0000; sFilterConfig.FilterFIFOAssignment = CAN_RX_FIFO0; sFilterConfig.FilterActivation = ENABLE; sFilterConfig.SlaveStartFilterBank = 14; if (HAL_CAN_ConfigFilter(&hcan1, &sFilterConfig) != HAL_OK) { Error_Handler(); }note:What value should come ?all I have configure as standard ID onlyEdited to apply source code formatting - please see 

For the Nucleo-575ZI-Q, while in stop mode 2, I have the capture module enabled, I set CH1 IO Usage as input.A square wave generator connected to PC1->LPTIM_CH1.While the Micro is in stop mode 2 an indeterminate number of pulses trigger successive captures.If the pulses on PC1 were odd CCR1 has the correct data.If the pulses on PC1 were even CCR1 value doesn't updated at all.Please note that all pulses arrive while STM32U575 is on stop mode. I made a very short project isolating the problem, the RTC is used to exit stop mode 2 every second, when waking up only CRR1 is read and returns to stop mode 2.   void FM_MAIN_Main() { uint16_t capture = 0; HAL_LPTIM_IC_Start(&hlptim1, LPTIM_CHANNEL_1); __HAL_RCC_LPTIM1_CLKAM_ENABLE(); for (;;) { HAL_GPIO_WritePin(LED_GPIO_Port, LED_Pin, GPIO_PIN_SET); capture = LPTIM1->CCR1; FM_DEBUG

Hello ST experts,Recently, I was developing a project with STM32H750I microcontroller, I faced a problem with ADC self-calibration HAL function (HAL_ADCEx_Calibration_Start)!I configured ADC1 and ADC2 in dual simultaneous mode + DMA + Timer with synchronous clock mode for clock Prescaler for both ADCs for better synchronization. I executed self-calibration function for ADC1 and ADC2 individually before activating Timer and DMA. The problem was that the microcontroller cannot finish the process. I checked the process only for ADC1. It was okay for ADC1. When I checked the process only for ADC2, it did not work. Also, I checked if I change timer Prescaler to the asynchronized clock mode, the self-calibration function will work. On the other hand, I miss ADCs synchronization. Therefore, I have to use synchronous mode for Clock Prescaler. Have you faced this problem in your projects? Could you please help me in this issue?

Hello, I am considering to use several STM32 microcontrollers to develop CANFD devices. I just saw CANFD Bosch specification v1.0, and more particularly scope 8 which defines the following requirements:Unfortunately, on all STM32 I have been confronted so far, you cannot specify exactly PROP seg and Phase seg 1 indivually but just the overall (Prop_seg+Phase_seg1). Which is fine to determine the sample point but I am not able to check if my bit timings are meeting the requirements above as I cannot discriminate prop seg length from phase 1 length.1. Is the dispatch between propseg and phase seg 1 constant over all devices ?2. Is

Hello ST Community,I’m working with the STM32 Nucleo-N657 board and need a way to execute my application after flashing to external memory without manually toggling the BOOT1 jumper on the board.What I’m Doing Now:BOOT1 jumper is set to HIGH for development (DEV boot mode)I have a simple LED blink application built with GPIO configured in the FSBL context The code runs as expected in DEV mode (debug mode of STM32CubeIDE)I then flashed the signed binary in external memory using STM32CubeProgrammer and External Memory loader for

Hi;In order to determine exactly the chip type I'd like to read the DBGMCU_IDCODE register. When I try to do this the bootloader hangs. RM0410 44.6.1 says "Only 32 bit access support". I guess the bootloader uses byte access.Is there a workaround?Reading UID and FLASHSIZE works just fine. 

Hi Folks,I'm working with an STM32G0B1MCT6. In my application I need to be able to react to pulses with a width of about 5 ns. It seems the only way I could pull this off is with the rising edge detection in the EXTI controller, or some additional external hardware. Datasheets for other products include a tEXTIpw parameter. I don't see a spec in either the reference manual or datasheet for the G0 series though. Help me ST - please can I have an official spec for this parameter on this series. Alternatively, do you have any recommendations for detecting short pulses without the EXTI peripheral? Cheers!

Hi,I’m working on the STM32G491 series. In my current project, the STM32 is configured as an I2C slave and communicates with another processor over I2C.When entering bootloader mode for flashing, the STM32 responds with the slave address 0x5F, which is also confirmed in the AN2606 application note.The issue is that the connected processor already has another I2C slave device using the same 0x5F address, and that device’s address cannot be changed.Is there any way to change the STM32’s I2C slave address in bootloader mode to avoid this conflict? 

Hi,I’m currently implementing I2C in slave mode using the STM32G491 series. Due to pin constraints, we’re considering using SCL and SDA pins from different GPIO ports—for example, SCL from port PA and SDA from port PC. Is it acceptable to assign I2C pins from different ports for a single peripheral?Also, we noticed a pin labeled I2C_SMBA. Could you explain its purpose? Can we use it for CLK or DATA?

Hi !I am evaluating the risks associated with STM32F3, where I am speculating a case where the voltage drops in VDD for few microseconds. For an example, let us assume the voltage drops from 3.3V to 3.0V for few microseconds. This occurs every x ms (assume 1 or 10). Now, 3.0V is still a good range, but will this constant voltage drops lead to any risks over longer time? Any corruption in flash memory or weakening of protection diodes, etc..??There are EMC related risks I understand from hardware perspective. What I am interested in is, the parts of controller that might be affected in the long run.Thanks!
