RSB-4810 CANFD support

Does the RSB-4810 support running CANFD? The product page indicates that it does, but it looks like the wiki is saying that it doesn’t.
I am able to bring up and use the CAN interface without a problem using just CAN 2.0, but only get an error if I try and bring up the interface in FD mode.


Looking at the dtsi file in the Debian 11 image it seems like the rk3568 is set to can-2.0 as opposed to canfd-1.0 that Debian 10 was set to.

HI Sir,
Due to the fact that Rockchip originally specified the functionality of CAN FD . After repeated testing by our software engineers, thus issue was still found and reported to Rockchip . After an extended period of coworking with Rockchip . They acknowledged that there was a design flaw in the initial specification and therefore they does not recommend using CAN FD. Only CAN 2.0 is supported. And we will also make the necessary changes the specifications in our web site. Thank you.
