I have multiple CAN FD Participant which are configured the same way:if (canFdMode == canFdModes_2mbit) { hfdcan1.Instance = FDCAN1; hfdcan1.Init.ClockDivider = FDCAN_CLOCK_DIV1; hfdcan1.Init.FrameFormat = FDCAN_FRAME_FD_BRS; hfdcan1.Init.Mod...

Hello,I tried to impelement a simple SPI Echo Slave.The Master transmits Data (Example for Nucleo 474RE - Master Full Duplex Interrupt) and the Slave waits for reception using HAL with a datasize of 1 Byte.After the Transfer is completed I am copying...

Thanks for the fast answer.For the sake of science, I tested it with a Circular 1 Byte DMA Buffer. Didn't work out either and caused the same behaviour 

Found the problem. I accidently overwrote the EEPROM Space after the direct Read after writing.

STM32G474 CAN FD no priorization of CAN IDs?

Simple SPI Echo Application drops receiving Bytes and sends undefined data (STM32G474RE)

Only 0 received when reading from M24128-BRMN6TP. Valid data received when reading directly after writing.
