Oleksij Rempel edcce70373 jcat: provide errqueue support 
The J1939 errqueue is a feedback interface to notify userspace
applications about actual transfer status. For now we can get
information about amount of data already send to the peer and errors
if session was aborted.

SocketCAN userspace utilities and tools

This repository contains some userspace utilities for Linux CAN subsystem (aka SocketCAN):

Basic tools to display, record, generate and replay CAN traffic

  • candump : display, filter and log CAN data to files
  • canplayer : replay CAN logfiles
  • cansend : send a single frame
  • cangen : generate (random) CAN traffic
  • cansniffer : display CAN data content differences (just 11bit CAN IDs)

CAN access via IP sockets

  • canlogserver : log CAN frames from a remote/local host
  • bcmserver : interactive BCM configuration (remote/local)
  • socketcand : use RAW/BCM/ISO-TP sockets via TCP/IP sockets

CAN in-kernel gateway configuration

  • cangw : CAN gateway userpace tool for netlink configuration

CAN bus measurement and testing

  • canbusload : calculate and display the CAN busload
  • can-calc-bit-timing : userspace version of in-kernel bitrate calculation
  • canfdtest : Full-duplex test program (DUT and host part)

ISO-TP tools ISO15765-2:2016 for Linux

  • isotpsend : send a single ISO-TP PDU
  • isotprecv : receive ISO-TP PDU(s)
  • isotpsniffer : 'wiretap' ISO-TP PDU(s)
  • isotpdump : 'wiretap' and interpret CAN messages (CAN_RAW)
  • isotpserver : IP server for simple TCP/IP <-> ISO 15765-2 bridging (ASCII HEX)
  • isotpperf : ISO15765-2 protocol performance visualisation
  • isotptun : create a bi-directional IP tunnel on CAN via ISO-TP

Log file converters

  • asc2log : convert ASC logfile to compact CAN frame logfile
  • log2asc : convert compact CAN frame logfile to ASC logfile
  • log2long : convert compact CAN frame representation into user readable

Serial Line Discipline configuration (for slcan driver)

  • slcan_attach : userspace tool for serial line CAN interface configuration
  • slcand : daemon for serial line CAN interface configuration
  • slcanpty : creates a pty for applications using the slcan ASCII protocol

CMake Project Generator

  • Place your build folder anywhere, passing CMake the path. Relative or absolute.
  • Some examples using a build folder under the source tree root:
  • Android : cmake -DCMAKE_TOOLCHAIN_FILE=~/Android/Sdk/ndk-bundle/build/cmake/android.toolchain.cmake -DANDROID_PLATFORM=android-21 -DANDROID_ABI=armeabi-v7a .. && make
  • Android Studio : Copy repo under your project's app folder, add add_subdirectory(can-utils) to your CMakeLists.txt file after cmake_minimum_required(). Generating project will build Debug/Release for all supported EABI types. ie. arm64-v8a, armeabi-v7a, x86, x86_64.
  • Raspberry Pi : cmake -DCMAKE_TOOLCHAIN_FILE=~/rpi/tools/build/cmake/rpi.toolchain.cmake .. && make
  • Linux : cmake -GNinja .. && ninja
  • Linux Eclipse Photon (Debug) : CC=clang cmake -G"Eclipse CDT4 - Unix Makefiles" ../can-utils/ -DCMAKE_BUILD_TYPE=Debug -DCMAKE_ECLIPSE_VERSION=4.8.0
  • To override the base installation directory use: CMAKE_INSTALL_PREFIX ie. CC=clang cmake -DCMAKE_INSTALL_PREFIX=./out .. && make install
