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...

STM32F205 - Support required for CAN filter MASK mode configuration

Hi all, Thanks for the support, I am using STM32 CAN filter in MASK mode. I required to filter the IDs that follow the J1939 requirements. So I required to filter the ID Group 1 and ID Group 2 using the two filter banksv(Bank 0, Bank 1, Other filter ...

We are having issue on stopping interrupt while doing Flash Erase.

Hi All,We are having issue on stopping interrupt while doing Flash Erase.What we are doing:1.    Unlocking flash.2.    Entering Critical Section by disabling ISR.3.    Erasing a Flash Page.4.    Waiting for operation to complete by checking busy flag...
