  • The CAN TX-FIFO is not used. instead the software FIFO is used, and only one CAN frame a time is fed into the CAN controllers hardware FIFO
  • The high priority TX buffer of the CAN controller is not used
  • Listen only mode not yet supported
  • The driver can be (and is) compiled with -DCANFD defined. For data transfer between application an driver long CAN frames with 64 byte date are used. Don't forget to specify it with all user code as well and the can4linux-examples. Using the CANFD flag the driver can be used in virtual CAN mode to simulate CAN-FD locally in a virtual CAN network and CAN controller hardware is not used.
  • Acceptance filter not used yet, All frames pass to the RX-FIFO
  • Both CAN0 and CAN1 can be used (CAN1 not tested yet because of limited hardware)
  • Error handling needs to be improved.
