4bit SDIO not working, but 1bit SDIO working fine.

I use CMSIS to write program that transfer data from SD card through SDIO. For my task i need 4bit mode, but it isn't working. When i try to read some block from SD card STBITERR bit in SDIO_STA register goes high, that means that start bit hasn't be...

Where can I get latest version CMSIS DSP lib ( .a file) (CMSIS version 5) file for STM32F7

[STM32H745XI] - Crystal oscillator failure

There is a problem with the start-up of both HF (25MHz) and RTC(32k) oscillators after a turn-OFF followed by immediate turn-ON (cca couple ms).Oscillators:EPSON FA-238 EPSON FA-135The RTC crystal does not start-up at all and the HF one does show ins...

Problem with GPIO Interrupts and RTOS STM32H753

Hello,I am using an STM32H753 mcu and I working on a project with 8 GPIO Interrupt Pins. I am using RTX RTOS. The problem is that when the interrupt happens the same time with a thread activation. The mcu goes in dummy handler with bus Precision erro...

When STM32G070RB SPI is received, both MOSI and MISO have returned data. The data is the same through the logic analyzer.

This is my test program：uint8_t dev_test=0x00;while(1){HAL_GPIO_WritePin(DW_NSS_GPIO_Port, DW_NSS_Pin, GPIO_PIN_RESET);HAL_SPI_Transmit(&hspi1,&dev_test,1,10);HAL_SPI_Receive(&hspi1,test_R,4,10);HAL_GPIO_WritePin(DW_NSS_GPIO_Port, DW_NSS_Pin, GPIO_PI...

Bus stall when writing/erasing flash on STM32H7

Hello,I am writing & erasing flash during operation, and this seems to cause a bus stall which prohibits all execution from flash during these operations.AN4808 seems to indicate that if you use a dual-bank device you can avoid this by executing out ...

Hello Experts I am beginner in STM32 , I have a old Discovery STM32 board , I want do some project, Now I require some already availabe libraires ,I dont know where can i get it ?Help me to findout ?

The HAL_TIM_PeriodElapsedHalfCpltCallback function doesn't generate an interrupt.

That's how it looks: Started the TIM4 interrupt mode:/* USER CODE BEGIN 2 */ HAL_TIM_Base_Start_IT(&htim4); /* USER CODE END 2 */The counter values should be incremented in the middle and in the end of the period, however it doesn't happen. There...
