DESCRIPTION

canfdtest - Full-duplex test program (DUT and host part).

OPTIONS

-b

(enable CAN FD Bit Rate Switch)

-d

(use CAN FD frames instead of classic CAN)

-e

(use 29-bit extended frame format instead of classic 11-bit one)

-f COUNT (number of frames in flight, default: 50)

-g

(generate messages)

-i ID

(CAN ID to use for frames to DUT (ping), default 77)

-l COUNT (test loop count)

-o ID

-s SIZE

(frame payload size in bytes)

-v

With the option '-g' CAN messages are generated and checked on <can-interface>, otherwise all messages received on the <can-interface> are sent back incrementing the CAN id and all data bytes. The program can be aborted with ^C.

EXAMPLES

on DUT:

canfdtest -v can0

on Host:

canfdtest -g -v can2
