STM32F427 SDIO Block Write with DMA not responding properly

I don't use libraries.My SD card interface is set up with an SDIO clock of 16.67 mhz using the 4-bit interface.My block write (SD command 24) works properly if I poll the data into the FIFO. The problem with that is the timing to push data into the F...

Audio Driver Issue on STM32F769I-Discovery board

I am using STM32F769I-Discovery board with STM32Cube_FW_F7_V1.16.0. I have the following issues on the audio driver functionality: I am trying to record the audio with sample audio application provided as part of this package. The driver by default ...

BusFault after Flash double-error detection and Flash IT not enabled

Hello,I am wondering if a BusFault is triggered when a double error is detected but the Flash IT (or the DBERRECC event) is not enabled ? 

STM32F746 SPI DMA Transmit and Receive issue.

Hello, I generated project with STM32CubeMX. I configured it in SPI slave with DMA Seems like memory increment mode in not working. When I check register DMA_SxCR MINC is off. But when I checked hdma_spi2_rx.Init.MemInc , its has correct DMA_MINC_E...

Strange behaviours of SPI bootloader on STM32F412

I'm developing a SPI bootloader, using the integrated function of STM32F412, and I found two strange behaviours:I must issue two times the reset of MCU with Boot0 high, because after the first reset the MCU seems to be in bootloader mode but doesn't ...

White screen with STM32F767 BITx microprocessor

Hi, I am working with a customized board which has STM32F767 BITx microprocessor. I made a simple application with TouchGFX 4.13.0 integred with STM32CubeIDE 1.2.0. The program builds and debugs correctly, but nothing appears on the screen, it is jus...

I Would like to use The STM32H743/753 processor that running up to 480 MHz. I'm Trying to figure if the processor will Succeed to run an Algorithm that contains X sum and multiplications in one sec. Is there any calculation that evaluate if its possible?

STM32H755 FMC NE, NWE multiple signal inquiry

STM32H755's FMC NE and NWE signals are different from the data sheet.STM32H755 is communicating with SRAM. Communication was performed by setting the data size to 1 using the HAL_SRAM_Write_16b function.The figure showing the signals of NE1 and NWE t...

UART bridge on STM32F0: data corruption

I'm trying to link together two UARTs to create a sort of "bridge". Each byte received by one of them is sent to the other and vice-versa. I used this code for 7-8 years on small and slow MCUs like xmega (8-bit and 32 MHz), so I think there should no...

Setting STM32H7 SAI port as asynchronous slave device

Hello,I'm trying to connect my DAC as a master device to STM32H7.I have configured SAI1 A as a Asynchronous Slave and SAI1 B as a synchronous slave.But I'm confused where to connect my DAC's MCLK output into.In other readings, LINK STM32L4 series hav...
