I am working with STM32G4 NUCLEO and STM32CubeIDE. Created a project to use FDCAN2 (classic mode) to evaluete CAN comm in polling mode. On FDCAN2 CAN messages are only received when I additionally activate FDCAN1.

FDCAN1 has a basic parameter 'Clock Divider' set to 'Divide kernal clock by 1'. FDCAN2 does not have this parameter. In library function HAL_FDCAN_INIT(...) there is a statement: /* Check FDCAN instance */ if (hfdcan->Instance == FDCAN1) {   /* Confi...

Unable to use SPI2 on PA12 PA11 PB15 with STM32H743

Hi,created some SPI2-slave code running on PB10(SCK), PB12(NSS) and PC3(MOSI) without problem. Needed to move SPI2 to other pins as PB12 will be used by RMII in later design. Decided to use PA12(SCK), PA11(NSS) and PB15(MOSI). SCK is running at 12.28...
