Using STM32G030C8Tx and I'm having a difficult time trying to erase flash.  The function returns with no error, and stepping through appears to work.  But the flash is not erased (viewing through CubeIDE memory explorer, and writes fail with `FLASH_SR_PGSERR`).  Here's the code: #define APP_START_PAGE (10) // Corresponds to 0x0800_4800, each page is 2kb #define NUMBER_OF_PAGES_TO_ERASE (22) uint32_t PageError; FLASH_EraseInitTypeDef flashErase_handle; static uint8_t execute_flash_erase(void) { HAL_StatusTypeDef status = HAL_OK; PageError = 0; // Configure the flash erase handle with the provided parameters flashErase_handle.TypeErase = FLASH_TYPEERASE_PAGES; flashErase_handle.Page = APP_START_PAGE; flashErase_handle.NbPages = NUMBER_OF_PAGES_TO_ERASE; flashErase_handle.Banks = FLASH_BANK_1; if (HAL_FLASH_Unlock() == HAL_OK) { status = HAL_FLASHEx_Erase(&flashE

Hi, my coupon code doesnt work, any help?

I have started with the Nx_WebServer demo application which requires the web content files to be loaded onto the SD card ahead of time. I am adapting the project to use a RAM file system instead of the SD card file system. However, I am struggling to find a simple way to create a byte array of the file system (at compile time) to place into the RAM linker section. Does anyone know of a utility to compile all of the web content files into a binary image of the complete file system so that it can be placed into the RAM region and used with the fx_media_open() function of FileX? ARM/Keil has the file converter utility FCARM that creates a byte array and image file structure from a directory of files, but not a file allocation table (the ARM Network Middleware that uses this image structure is closed source). I could create a new RAM file system at initialization and loop through the file structure array created by FCARM to add each file to the file

I have two SPI buses activated SPI1 (flash memory) and SPI3 (nrf24l01) on my STM32F407. Separately, they work fine. But, if I transfer something via SPI1, SPI3 read from the register always returns 0 (and in DR register for SPI3 is also 0, BUT sometimes it has value 3 (though has to be 46)). And I don't know where to look and dig dipper. Let me know if you need additional code or screenshots. 

The memory map shown on page 76 of the reference manual for the stm32f76xxx shows the following figure:I believe the addresses in blocks 5...6 are not correct and that it should be as follows:  

It looks like simply replacing the QSPI loader files, which are available on github (CubeIDE)but not all is exactly the same.for example the are functions likeOSPI_OctalModeCfg(&hospi1);do I need to call it somewhere ? so far the loader for QSPI is working fine but OSPI is coming so far with bunch of errors.

ReadAddr should increment by 1. The current routine delivers junk for multi-sector reads/writes. Please, please, test these things, wasted a lot of time chasing this to ground. Original code ... response = SD_SendCmd(SD_CMD_READ_SINGLE_BLOCK, (ReadAddr + offset) * (flag_SDHC == 1 ? 1: BlockSize), 0xFF, SD_ANSWER_R1_EXPECTED); ... /* Set next read address*/ offset += BlockSize; Suggested fix (I'd probably refactor completely) ... response = SD_SendCmd(SD_CMD_READ_SINGLE_BLOCK, ReadAddr * ((flag_SDHC == 1) ? 1: BlockSize), 0xFF, SD_ANSWER_R1_EXPECTED); ... /* Set next read address*/ ReadAddr++; // Block Address offset += BlockSize;

Hi,I am building a product where I have to store calibration data and retain it even after power off.I am using the STM32H745ZiT6 and would like to use its flash to read/write data. As I have setup communication between the two cores I have the current setup on the MPU:void MPU_Config(void){MPU_Region_InitTypeDef MPU_InitStruct = {0};/* Disables the MPU */HAL_MPU_Disable();/** Initializes and configures the Region and the memory to be protected*/MPU_InitStruct.Enable = MPU_REGION_ENABLE;MPU_InitStruct.Number = MPU_REGION_NUMBER0;MPU_InitStruct.BaseAddress = 0x38000000;MPU_InitStruct.Size = MPU_REGION_SIZE_64KB;

I’m experiencing an issue while developing firmware on a STM32L431CCU6 connected to: Xbee module (XB3-24Z8CM-J) via UART1RS485 driver (ST1480ABDR_ Via UART2 HAL_NVIC_SetPriority(USART1_IRQn, 0, 0); HAL_NVIC_EnableIRQ(USART1_IRQn); HAL_NVIC_SetPriority(USART3_IRQn, 2, 0); HAL_NVIC_EnableIRQ(USART3_IRQn); The communication to the xbee works perfectly fine until the RS485 interface is polled at which point nothing is received via UART1 (no interrupt recorded), I’ve checked the interrupt priorities and UART1 has a higher priority.Each interface works on its own but when attempting to use the interfaces together it seems to have a conflict somewhere. Would you have any suggestion/recommendations? Appreciate any help and thanks in advance.   if(huart == &amp

I'm trying to use the HRTIM TimerA on the STM32-G474 to generate a one pulse on TA1 output in response to an external event on hrtim_eev1.I need the pulse to be generate with low latency and low jitter, but I'm not being able to get the Fast mode working.I've configured external event 1 with level sensing and asynchronous action in CubeMX, but I continue getting high response time latency (>7 cycles of fHRTIM) and a response time jitter of 1 cycle of fHRTIM clock (5.8ns), instead of the minimum jitter I would expect. Also, pulse width has no jitter, as expected when FastMode is disabled.I start the timer with the HAL_HRTIM_SimpleOnePulseStart function. Afterwards the EE1FAST register (HRTIM_Common->EECR1->EE1FAST) is 0.I've tried to set it by hand, but with no results.CubeMX settings are as follows:

Hello  we Have Custom Build PCB Board where we Mounted SD card Interface and Using stm32f4xx_HAL_SD.c Library file in which 512 byte Hard Coded as config.DataBlockSize = SDIO_DATABLOCK_SIZE_512B;, but we have to write Byte  means don't block size of 512 Byte. So as i Went through Transcend Sd Card There they Recommended Something WRITE_BL_PARTIAL , if WRITE_BL_PARTIAL =0 means 512 Byte Block Size and WRITE_BL_PARTIAL =1 means Small Block Size that is 1 Byte. So how we can Enable or Disable  WRITE_BL_PARTIAL in  stm32f4xx_HAL_SD.c . Anyone Have Idea how we can do ?   Thank You

Hi everyone,I'm facing an issue with using DMA1 for SPI communication in my project. I'm trying to achieve a 2 kHz frequency, but DMA1 doesn't seem to work at this rate, whereas BDMA functions without any problems. This is my sampling task that is called with a timer interrupt, if (!g_xGxStatus.txOngoing) { g_xGxStatus.sampleReady = IsDataReady(&pxHandler->s1); if (g_xGxStatus.sampleReady) { g_xGxStatus.txOngoing = true; HAL_GPIO_WritePin(pxHandler->s1.csPort, pxHandler->s1.csPin, GPIO_PIN_RESET); HAL_SPI_TransmitReceive_DMA(pxHandler->s1.pxSpi, (uint8_t*) DMA_TxBuffer1, (uint8_t*) DMA_RxBufferGyro1, 6); } } if (!g_xGyStatus.txOngoing && !g_xGzStatus.txOngoing) { if (Sel == 2) { g_xGyStatus.sampleReady = IsDataReady(&pxHandler->s3); if (g_xGyStatus.sampleReady) { g_xGyStatus.txOngoing = true; HAL_GPIO_WritePin(pxHandler->s2.csPort, pxHandler->s2.csPin, GP

I am trying to use second half of OCTOSPI pins in single memory mode by setting MSEL bit for QUAD SPI communication with Flash memory. Even though i set the MSEL bit to send the data through 7 to 4 pins, still data is going through the 3 to 0 pin only. Am i missing something in configuration? Please see the below code for your reference.  uint8_tXSPI_WriteEnable_IO_7_4(void) {XSPI_RegularCmdTypeDef sCommand;XSPI_AutoPollingTypeDef sConfig; /* Enable write operations ------------------------------------------ */sCommand.OperationType = HAL_XSPI_OPTYPE_COMMON_CFG;sCommand.IOSelect = HAL_XSPI_SELECT_IO_7_4;sCommand.Instruction = WRITE_ENABLE_CMD;sCommand.InstructionMode = HAL_XSPI_INSTRUCTION_1_LINE;sCommand.InstructionWidth = HAL_XSPI_INSTRUCTION_8_BITS;sCommand.InstructionDTRMode = HAL_XSPI_INSTRUCTION_DTR_DISABLE;sCommand.Address = HAL_XSPI

Hi, my program required a large amount of RAM memory, how can i know which external memory i can choose? and which peripheral is dedicated for this? 

We encountered an issue with the SPI3 peripheral on F4xx and F7xx series chips where the RXNE bit of the status register would be set right after enabling the SPI peripheral after re-configuring it.This is clearly impossible as no transaction is performed at that time yet, and reading the DR further proves it: random data is read. We have reasons to believe this is a hardware bug. No other SPI peripheral exhibits this behavior, this only happens for SPI3.We always use the SPI peripheral in 8 bit frame mode, with software slave management and with various clock divider settings (which do not affect the behavior).We have always made the assumption that RXNE should be `0` at the beginning of a transaction, more so because we empty the RX queue at the end of each transaction. We placed an `assert((SPIx->SR & SPI_SR_RXNE) == 0)` at the beginning of the transaction code, to enforce this assumption.We started to notice random reboots of our boards, when run

Hello,After setting up a 4 channel read with DMA, I ran into the problem, that the value of the internal temperature sensor seemed to not change at all. The values of the read out potentiometer however were plausible.So I wanted to check all used channels by manually polling them.But in this case it seems that the EOS flag is set before the loop finishes reading the data, though I have the WAIT bit set in CFGR1. if( (this->adcReg->ISR & ADC_ISR_ADRDY) != 0 ) this->adcReg->CR |= ADC_CR_ADSTART; for( uint8_t index = 0; index < this->numOfChannels; index++){ while( (this->adcReg->ISR & ADC_ISR_EOC) != 1 ); this->adcData[index] = this->adcReg->DR; } So here my debugger runs to infinity stuck in the while loop with index = 2 and adcData[0] and [1] having data.Do you have ideas why this isn't working? I also read in the forum, that multichan

Hi There,I have searched a lot about the  HAL_I2C_Mem_Write_DMA problem and seems like i have not found anywhere else this issue has been solved.Can anyone contribute if someone has solved it. Thanks

Hi, I'm having issues on our custom board jumping to the system memory bootrom.Likely i have a software issue but would like to clarify the system memory address for the bootloader. This is usually listed in AN2606 but there is no explicit mention of the STM32h7b0.https://www.st.com/resource/en/application_note/cd00167594-stm32-microcontroller-system-memory-boot-mode-stmicroelectronics.pdfI've been assuming that it is the same as the STM32h7b3 as its just a low flash varient, But as I'm facing issues it would be good to confirm.Tim

I'm a beginner at STM processor, and I'm trying programming software interrupt using GPIO port as EXTI line at STM32L4R5QI(STM32L4+ series) processor.Then, I was wondering when I was reading the reference manual of STM32L4+ series.  It seems that the EXTI interrupt is OR condition between the hardware interrupt signal and software interrupt signal as below:In addition, for using EXTI line, I configured the GPIO port as EXTI and configured GPIO mode at STM32CubeMX as below:

I've followed some answers from a post here:https://stackoverflow.com/questions/57283327/how-to-change-the-uart-baud-rate-after-running-on-stm32-boardBut still can't seem to get the baud rate to change.

Hi all,          I have working on USBPD Sink project in that ,I have been struck in the part of reading the voltage from the STM32L562CET6(Customized Board)before this process I have done the same project in STM32L562E-DK , What I need to do actually to overcome the issue of mine?  

Hi,I was measuring the STM32F373 core temperature.It seems that the core is 56°C while the environment is 23°C, no housing.Is the 56°C a reasonable temperature? It looks quite high to me.I used the settings below:

Hello. I am writing a code to read ADC data from an AC voltage sensor. I used HAL to initialize ADC 1 and USART2 for checking the values in Putty. However, I would like to use direct register manipulation to send data to USART6 so that it can transmit the data to a wifi module which sends the data to a website for monitoring. However, I am not getting correct values in USART6 (confirmed by using serial monitor in IDE which I am using to check data received by the wifi module which is ESP32 to be specific). The output is gibberish as opposed to the data obtained from USART2. Is it possible that there's clashing between the initialization of USART2 in HAL and USART6 in bare metal?If I try using bare metal for USART2 and USART6, would there be any difference? I have read from another question here that you cannot mix HAL and bare metal code when accessing the same peripheral, but I wonder if that applies for the GPIO peripherals I'd be using as well (ADC GPIOs in HAL and US

HelloWhat will happen with the IOs when MCU is put to Sleep mode (one of power modes in PWR) and register bits in RCC_AHB2LPENR for each GPIO-block are reset? When bits are reset, the peripheral clock is disabled during Sleep mode.Can the IOs still be used to trigger interrupts in Sleep mode with the EXTI controller?
