| The CAN FD protocol was recently enhanced regarding the CRC weakness in the original Bosch paper.

| The Linux CAN device driver [[http://sourceforge.net/projects/can4linux/|can4linux]] supports this frame format already in it's 'virtual' mode. The same is true for the [[http://www.kernel.org/doc/Documentation/networking/can.txt | SocketCAN]] approach. Since May 2014 a version of [[http://sourceforge.net/projects/can4linux/|can4linux]] is available with real hardware support for the [[http://www.ifi-pld.de/IP/CANFD/canfd.html |IFI non-ISO CAN FD]] controller. | The Linux CAN device driver [[http://sourceforge.net/projects/can4linux/|can4linux]] supports this frame format already in it's 'virtual' mode.
