Hi community,I am observing Hardfault exception when trying to program internal flash of stm32g030k6t6 MCU in FAST mode . is there anyother FLASH registers i need to enable ?I have attached the code here static void write_data_to_application(void) { //uint32_t *flash_address = (uint32_t *)FLASH_USER_END_ADDR ; uint32_t flash_address = 0x08007C00 ; HAL_StatusTypeDef status = HAL_OK; HAL_FLASH_Unlock(); status = HAL_FLASH_Program(FLASH_TYPEPROGRAM_FAST, (uint32_t)flash_address, (uint64_t)0xDEAD1731); HAL_FLASH_Lock(); } Thanks Narendra C@TDK 

I am trying to receive a frame containing 10 bytes of serial data, each frame is transmitted at a 100ms rate.However, as the UART can start receiving the 10 byte frame at any point in time, the received data is becoming out of sync. How do I sync the UART peripheral so that it always starts receiving at the start of the 10 byte frame ?Below is a scope capture of the 10 bytes of serial data:Below is a scope capture of the 10 bytes of serial data being sent at a 100ms rate:

Hello,I wonder if it is or it is not possible to use more than one ADC independet of each other. My problem is as follows: I want to use ADC1 and ADC2  in independent scan conversion nothing works anymore. My code work for ADC1 alone   or ADC2 alone,     uint32_t courant1;// TENSION VIA LE CAPTEUR uint32_t courant2;// TENSION VIA LE CAPTEUR /* Private variables ---------------------------------------------------------*/ ADC_HandleTypeDef hadc2; ADC_HandleTypeDef hadc3; /* Private function prototypes -----------------------------------------------*/ void SystemClock_Config(void); static void MX_GPIO_Init(void); static void MX_ADC2_Init(void); static void MX_ADC3_Init(void); /* USER CODE BEGIN PFP */ void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef* hadc) { if (hadc->Instance == ADC3) { courant1=HAL_ADC_GetVa

Hello,We encountered a problem with the internal Bootloader of the STM32G0B1KBU6 MCU.ConditionsFirst, the option bytes are set with an STLINK-V3 programming adapter (SWD interface) and CubeProgrammer (2.15.0) according to Pattern 11 of AN2606:nBoot_SEL => uncheckednboot1 => checkednboot0 => uncheckedReproduction1. In our product assembly process:Initial programming of the user software is successful with STLINK-V3 Programming Adapter via SWD interface. Stm32flashtool is used to flash the controller at I2C address 0x5d. Pin PB6 and PB7 are used to access I2C bootloader.2. Trying to reprogram the controller while testing:Now, with the software already running on STM32G0B1KBU6 (verified) we go through the STM bootloader activation Pattern 11 (AN2606, Sec. 4.1) with pulling boot0 and reset low, then pulling boot0 and afterwards reset high.Expected

Hello Team,I have implemented ADC_DMA (circular mode) Multiple channels in NUCLEO_H745 and in that added ethernet without RTOS when ethernet is implement ADC_DMA is not working it provide only one time data but i have configured for circular mode every 1HZ I need to get new data but after ethernet is implemented I am getting only I time data, So is there any memory mapping I need change any configuration in code?PFA BelowBest Regards,Gagan Gowda G R

I do not have any output via SWV or via COM port debugging using a STM32H723ZGTX.I am using a nucleo ST-link breakoff board to program with no issue.I have tried solutions provided in both following threads:https://community.st.com/t5/other-tools-mcus/no-traceswo-output-on-stm32h7xx/m-p/395490https://community.st.com/t5/stm32-mcus/how-to-redirect-the-printf-function-to-a-uart-for-debug-messages/ta-p/49865Any suggestions would be much appreciated.   

Hi,Is there any information available regarding the process variation of the ADC12 ENOB in the STM32H747 operated as a differential ADC? With a custom PCB we are seeing a standard deviation of 2.73 bits, which is quite substantial. On the worst offending prototype unit, we have an ENOB of just 10.5 bits. With this device, even if we short together the inputs and connect to 1/2 VREF (buffered from the internal device VREF output buffer with 1.1 uF decoupling capacitance), the ENOB does not improve above ~12 bits, 1.7 bits below the typical ENOB indicated on the datasheet. Although the top-end performance of the ADCs is very strong, the amount of device-to-device variation we're seeing is creating some hesitation among our staff to bring this board to production as currently designed. Thanks!

Hello,in my application, exiting from STOP3 mode is working fine but when the SRAM is over 192K, so getting SRAM2 addresses, exiting from STOP3 mode is forcing watchdog reset (I think when is trying to access a variable placed on SRAM2)  however from STOP2 mode is working fine.In STM32IDE debug mode everything is working fine too, so I´m totally blind and I can´t get any clue in the reference manual.Anyone could help me, please? Thank you.

Hi, is it necesarry to use a crystal oscilator for DFU USB booltloader for STM32F427zit? Can I use a generator instead of crystal? Marcin

Hi all, im using Cube IDE STM32H743ZI2 Evaluation boardim curently sampling ADC2 and storing the output at an internal array using DMAthe array size is uint16_t[100,000]my requirements as to store much more data which means i have to use a diffrent memory sector.i was hoping i could use flash for that matter but the examples that i tried online.i was wondering is that kind of thing even possible?do i need some external flash memory for that matter?my final goal would be storing around 1M samples during about 1-2 seconds  which sums up at about 1Mbwhat is the right approach for that matter?according to the reference manual i should be able to access flash memory via D2->D1 AHB BUSThanks! :)

Hello,I recently upgraded to CubeIde 1.6.0 but I am having many new problems when programming STM32h/43: the configurations generation is much slower and it often stops updating all needed files, which forces me to reboot (I could not find a better way).So I decided to downgrade to 1.5.1 which was stable for me, but I cannot load the .ioc files that were generated with 1.6.0. Is there a workaround?

I need USB interface STM32F373 for circuit.

Three states on a single GPIO pin with two LEDs is possible.For users who want to drive 2 LEDs with three states with one signal GPIO - please, see the details below.But I want to ask one question:On a STM32U5A5 - how does the PC13 behave? - I see "FOUR states" possible (even I can force later just to use three states).MCU was never flashed with a FW: both LEDs are on (dimmed, like getting pulses)both LEDs off: configure PC13 as input (or GPIO_DeInit() to set as analog pin)LED1 on / LED2 off: configured as output and drive lowLED1 off / LED2 on: configure as output and drive highI cannot force again to see both LEDs on.But I am sure: after I have soldered my boards, power it up the first t

Hello,I have some questions regarding Ethernet frame transmission.1) When is the value of the "ETH_MMCTGFCR" register increased?After calling the "HAL_ETH_TransmitFrame()" function, I noticed that the value of the "ETH_MMCTGFCR" register increased in just under 1 millisecond. Could you please inform me about when the register is increased? Is it incremented after the frame is transmitted to the PHY?2) After transmission, is there a possibility of approximately a 20 ms delay in the receiver?I have verified the timing using Wireshark. I have configured my device to send an ETH frame to my laptop every 128 ms. The value of the "ETH_MMCTGFCR" register increases in less than 1 ms after calling the "HAL_ETH_TransmitFrame()" function. However, when I check the received time of the packet in my laptop with Wireshark, I observe occasional jitter. I have also attached the screenshot.

Hi,I am Using an stm32f205 on our board. All the Uarts works fine at room temperature. But when the temp increases above 58 degress, messages started get missed in the uarts or sometimes it completely stops sending messages.I am running the board at 120MHZ Here is my clock setup RCC_OscInitTypeDef RCC_OscInitStruct = {0};  RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI;  RCC_OscInitStruct.HSIState = RCC_HSI_ON;  RCC_OscInitStruct.HSICalibrationValue = RCC_HSICALIBRATION_DEFAULT;  RCC_OscInitStruct

In STM32L432KC(arm cortex-m4+FPU) there are two ram memory blocks. Following is a snippet from the linker script I use._e_ram2_stack = ORIGIN(RAM2) + LENGTH(RAM2); _e_ram_stack = ORIGIN(RAM ) + LENGTH(RAM ); ... RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 64K RAM2 (xrw) : ORIGIN = 0x10000000, LENGTH = 16KI can set main stack pointer(MSP) to use `_e_ram_stack` or `_e_ram2_stack` without problem. However when I try to set thread mode to use process stack pointer(PSP) I start to get `INVPC` hard fault on SysTick interrupt return `pop {r7, pc}` instruction.If I subtract 112 from `_e_ram_stack` or `_e_ram2_stack`, only then I can start using PSP without problem. Something is preventing the use of end of memory address as top of the stack for PSP, but I couldn't find anything related to that in ARMv7-m architecture manual.Following is the only change I did in the project code of STM32CubeIDE. Main program is ju

 I have successfully configured USB On-The-Go (OTG) on an STM32 microcontroller to support both Abstract Control Model (ACM) and Human Interface Device (HID) protocols. I utilized the stm32_usbotg_eth_config.sh script as a reference, and the setup is functioning as intended.Now, I am seeking guidance on modifying the USB configuration to initially support only the HID protocol. Subsequently, I aim to dynamically enable the ACM protocol when specific events occur. To achieve this, I have adapted the script to exclusively open the HID protocol and created another script to open the ACM protocol as well.While the second script is functional, I have observed that in order to detect the ACM functionality on my Windows computer, I need to disable the gadget (echo ""

I need to measure the time it takes for a component to reach a certain voltage, read out with the ADC. So far I have been measuring in microseconds but it turned out that that is not precise enough.I found the following code to measure time on Stackoverflow and it works well, but I only superficially understand it and I can't really modify it.// setup__HAL_RCC_TIM2_CLK_ENABLE();TIM2->PSC = HAL_RCC_GetPCLK1Freq()/1000000 - 1;TIM2->CR1 = TIM_CR1_CEN;// read time in microsecondstime_start = TIM2->CNT;Can someone explain to me how it works and if I can modify it to measure nanoseconds? There might a super obvious way to do it but, again, I don't understand the code (This is what

Dear Community,I've got STM32H730 with ext Flash on OCTOSPI2 and ext RAM (s70kl1283) on OCTOSPI1.I call  SCB_EnableICache(); and  SCB_EnableDCache(); early in main, then I configure the MPU.I've got no problems executing code from ext Flash/OCTOSPI2 when MPU is configured as follows:MPU_InitStruct.Enable = MPU_REGION_ENABLE;MPU_InitStruct.BaseAddress = OCTOSPI2_BASE;MPU_InitStruct.Size = MPU_REGION_SIZE_16MB;MPU_InitStruct.AccessPermission = MPU_REGION_FULL_ACCESS;MPU_InitStruct.IsBufferable = MPU_ACCESS_BUFFERABLE;MPU_InitStruct.IsCacheable = MPU_ACCESS_CACHEABLE;MPU_InitStruct.IsShareable = MPU_ACCESS_SHAREABLE;MPU_InitStruct.Number = MPU_REGION_NUMBER4;MPU_InitStruct.TypeExtField = MPU_TEX_LEVEL0;MPU_InitStruct.SubRegionDisable = 0x00;MPU_InitStruct.DisableExec = MPU_INSTRUCTION_ACCESS_ENABLE;HAL_MPU_ConfigRegion(&MPU_InitStruct);It has a big, measurable impact on th

Hi, i come across a H7 code that use HAL_StatusTypeDef , could anyone kindly advise what does the HAL_StatusTypeDef do, whats HAL_OK means? what does ret != HAL_OK mean? and what does return HAL_OK means?HAL_StatusTypeDef spi_write(reg, *pData){  HAL_StatusTypeDef ret;  uint8_t sendData[2] = {reg, *pData};   HAL_GPIO_WritePin(...SPI1_CS_Pin, 0);  // CS pull low  ret = HAL_SPI_Transmit(&hspi1, sendData, 2, 20);  if  (ret != HAL_OK)  {              HAL_GPIO_WritePin(.., SPI1_CS_Pin, 1);  // CS pull high              return ret;  }

Hi all,   I have a problem which is bugging me as I can't figure out what im doing wrong. I am trying to read from ADC_IN4 but are reading wrong values. I should be reading apprx. 30000 ADC value but i am reading apprx. 7800. I think that this indicates that i am not reading from the right channel because there is a LM20 temperature sensor connected to PC3 which is ADC_IN4 on stm32L475x and the value does not change if i apply heat or cold. I want the TIM4_TRGO event to trigger ADC conversions with 16x oversampling, and at sequence end, trigger EOS interrupt where i read the ADC data. Later on i want to connect it to DMA. I have never really worked with update events on stm32 so I think I am maybe doing something wrong setting up the update events, maybe im mixing up interrupts and events, or the ADC channel configuration is wrong. I really hope someone can help me.

Hello,I keep getting an NMI fault when I attempt to read a variable with gdb (either with a mouseover on a variable in STM32CubeIDE or the print [var] command in gdb). I'm not seeing anything useful when I view the microprocessor registers after the fault.I'm using the stm32g474 hal library along with a linker, startup file, and interrupt _it files that are normally generated by default with the STM32CubeMX software for a G474 nucleo board. However, I'm using cmake 2.47.6 and the arm gcc/g++ toolchain 11.2-2022.02 for the build process.Thank you
