STM32 MCUs Embedded software

STM32 SPI Bootloader start up application failed.

Hello Together,​Currently, I met an issue about the internal bootloader download application by SPI.​Firstly, let me describe the background.MCU, STM32F750V8 rev, ZTaget, I want to use the internal SPI bootloader to download the application from the ...

Audio class device problem

HelloI am trying to configure my STM32F411CEU as a audio device class. After research i configured everything in STM32CubeMX and loaded program to my MCU. Plugged usb to the PC and it seems that PC sees it as some audio device but it says that it ca...

FreeRTOS task switching issue.

Hello,I am facing problem with task switching in FreeRTOS. I am using my custom board with STM32L476RC running at 80 MHz clock. Using STM32CubeIDE and configured project using CubeMX. I am using 3 tasks. Task 1 has some functions which uses osDelay ...

STM32L462 FATFS+FREERTOS+DMA disk_ioctl causes Hard fault interrupt

I'm using custom board with stm32l462re with sd card.Without freertos and dma i'm able to write/read to sd card (32MHz on sdmmc clock, 1 bit mode, 10 clock divide factor). As project grows I decided to use freertos.But now f_open send hard fault (dis...

STM32F429 power loss during write to flash bricks device

HiI've implemented the dual boot functionality on my STM32F429 for OTA Updates.To do so, I always write the new firmware into 0x08100000 and afterwards set oder reset the dual boot bit.If I cut the power to the MCU during the writing process to the n...

How to obtain version information of used packedge at runtime. In cube config file it can be looked up (for example V1.8.0), but how to get it runtime in code?

Is there a limitation on the buffer length parameter to HAL_ADCEx_MultiModeStart_DMA? Length 32767 * 2 is OK and gives HAL_ADC_ConvHalfCpltCallback and HAL_ADC_ConvCpltCallback interrupts but 32768 * 2 fails with no interrupts.

I use STM32H753IITx and there is space in RAM_D1 to use length 2*65536.I call like this: if (HAL_ADCEx_MultiModeStart_DMA(&hadc1, guiaAdc12Data, (uint32_t)(ADC12_MAX_COUNT * 2)) != HAL_OK) { Error_Handler(); }

I curently work on bootloader for stm32 via uart link and manage to update the bootloader, if i use a character by character method via uart+interuption on TX side.But if I work with DMA to send characters the bootloader doesn't recognize command ?
