Hi, A related company manufactures a few CAN based products, and communicates with them from Linux (and a long time ago, Windows CE). The devices perform various on-board functions in metros, including audio streaming, so our driver requirements are a little different to (say) SocketCAN. We have an upcoming requirement to implement an appliance for use in maintenance and repairs, and I’d like to do that based on FreeBSD. I haven’t started looking at this yet, but I’m certainly interested how CAN might progress on FreeBSD. Regards, Jan M. > On 9.
