Great ST Community,Problem:Why do I have random duplicate frames on the CAN bus with a STM32G474?Context:I am using STM32G474 ;I am using FDCAN1 (can not try with FDCAN2) with Classical CAN frames ;STM32Cube FW_G4 V1.4.0 ;STM32CubeIDE 1.7.0 ;I used t...

Hello all and @Community member ,We have bought a STM32G474E-EVAL (evaluation board) and used "FDCAN_Classic_Frame_Networking" example to communicate at 500 kBauds (so need to adapt example: nominal time segments mainly) with a STM32F7 => The STM32G...

Hi @Community member You are right! And thanks for your answer.But below, you can find my understanding:From FDCAN examples provide by STM32CubeIDE to STM32G4 (and others) to send Classical CAN frames, FDCAN peripherical is set to FDCAN_FRAME_FD_BRS...
