Hi,

I cannot presently point to a Cyclone V HPS register definition or document explicitly proving triple sampling is implemented/enabled in Cyclone V HPS CAN. I will further check internally.

Have you tried "$ ip -details link show can0"?

If the Linux driver exposes: triple-sampling on/off

then the underlying controller/driver combination should support it.

    Thanks.

    Unfortunately we aren't running Linux on our Cyclone V devices, so I can't quickly check via the driver.
    I'll try to find the evaluation boards we got over 10 years ago and try to get Linux running on them.
