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 ?

HAL_UART_Receive_DMA calls RxCpltCallback, but receives no data

In my project, I'm using UART1 with DMA enabled, similar to this:MX_GPIO_Init(); MX_DMA_Init(); MX_UART7_Init(); // initializes, and I assume, correctly   void DMA1_Stream1_IRQHandler(void) { HAL_DMA_IRQHandler(&hdma_uart7_tx); }   void DMA1_Stream...

sprintf, FreeRTOS, Hard Fault and Stack aligment, need explanation

Hello!I encounter random HardFault when calling sprintf, sscanf from thread context in FreeRTOS. MCU is F446. When called before KernelStart, it works well. Meanwhile, it was working ok, before I`ve rearanged modules and added new structures. I didn`...
