## NAME

canfdtest - manual page for canfdtest 2023.03-1

## SYNOPSIS

**canfdtest** \[*options*\] *\<can-interface\>*

## 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

  (CAN ID to use for frames to host (pong), default 78)

- **-s** SIZE

  (frame payload size in bytes)

- **-v**

  (low verbosity)

- **-vv**

  (high verbosity)

- **-x**

  (ignore other frames on bus)

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
