i.MX8M Plus CAN FD setsockopt() fails in C code

abhayaugustin1 — Mon, 28 Jul 2025 05:21:59 GMT

What is the correct function commands to open a socket , enable canfd frames and bind to the interface .The socket should receive bit rate switchcing frames.
ip link set can0 up type can bitrate 500000 dbitrate 2000000 fd on //This is the command i use to enable can interface

Currently i am using :

socket(PF_CAN, SOCK_RAW , CAN_RAW);

setsockopt(sock, SOL_CAN_RAW, CAN_RAW_FD_FRAMES, &enable_canfd, sizeof(enable_canfd));
setsockopt is giving me error code 22 (EINVAL).

what are the correct arguements for :
socket();
setsockopt();

CAN-FD is not supported on the consumer version of i.MX 8M Plus, it is only available on the Industrial version.

Unfortunately on the 8MP EVK, the consumer version is installed, so i.MX 8M Plus EVK not support CAN-FD feature.
