CAN FIFO filling faster than flushing

We set up classic CAN on the stm32h747I-DISCO dev board and listen for interrupts on every message:extern "C" void HAL_FDCAN_RxFifo0Callback(fdcan_handle* hfdcan, std::uint32_t RxFifo0ITs) { if ((RxFifo0ITs & FDCAN_IT_RX_FIFO0_FULL) != RESET) ...

FMPI2C DMA Not working - STM32F446

Hello All, I am trying to talk to an FRAM over FMPI2C on the STM32F446 using DMA, but the DMA is not able to "start". I am using the Mem_Write_DMA function in stm32f4xx_hal_fmpi2c.c.When I do a side by side comparison with the Mem_Write_DMA function ...

reserving high-cycle flash

What's the difference between enabling high cycle flash from option bytes on an H5 versus just using that section of flash by reserving it in the linker instead, apart from the ECC change?

debug and code non corresponding

I have an application that debugs correctly when I loads it at address 0x08000000.I'd like to use a bootloader, so I've changed the ld file, and choose, as flash origin, the address FLASH (rx) : ORIGIN = 0x08020000, LENGTH = 1920KBut, in this case, w...

Resolved! STM32U5A5 Hard fault setting SYSCLK > 64Mhz

I'm trying to crank up the clock to Timer1 to be able to count high frequency events with better resolution.  If I set the SYSCLK to 128 I get a hard fault when my code reaches SystemClock_Config().  Even if I keep the AHB bus at the same speed (64Mh...
