Use kvaser

Kernel 3.10

1. First test without install of driver and without kvaser leaf connected.

Check support before install of driver:

sudo cat /boot/config-3.10.0-1127.el7.x86_64  | grep KVASER
CONFIG_CAN_KVASER_PCI=m
CONFIG_CAN_KVASER_USB=m

Seems support for KVASER_USB already without installing.

Check ip addr:

ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether c0:3f:d5:66:25:44 brd ff:ff:ff:ff:ff:ff
    inet 172.30.2.34/27 brd 172.30.2.63 scope global noprefixroute dynamic eno1
       valid_lft 9999557sec preferred_lft 9999557sec
    inet6 fe80::c23f:d5ff:fe66:2544/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever

Seems no can interface (and it's not connected).

2. Connect kvaser leaf:

Check ip addr:

ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether c0:3f:d5:66:25:44 brd ff:ff:ff:ff:ff:ff
    inet 172.30.2.34/27 brd 172.30.2.63 scope global noprefixroute dynamic eno1
       valid_lft 9999557sec preferred_lft 9999557sec
    inet6 fe80::c23f:d5ff:fe66:2544/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever

Still no can0...

dmesg:[  543.068096] usb 2-4: new high-speed USB device number 4 using xhci_hcd
[  543.191792] usb 2-4: New USB device found, idVendor=0bfd, idProduct=0120, bcdDevice= 0.01

3. Try start services and conf if

Services

Start services:

$ sudo modprobe can_dev
$ sudo modprobe can
$ sudo modprobe can_raw
$ sudo ip link set can0 type can bitrate 125000

Conclusion: Cannot find can0.. Need to install kvaser driver..

Insall kvaser socketcan 3.10

1 unplug kvaser leaf

2 untar driver source

cd kvaser
tar -xvf socketcan_kvaser_drivers_for_3.10.tar 
cd socketcan_kvaser_drivers/

NOTE: The socketcan_kvaser_drivers_for_3.10.tar was recived on request from kvaser support. Their normal socketcan driver will not support kernel 3.10.

3 make

Read the README file in kvaser driver. These commands are from that README:

$ sudo make uninstall
$ make
$ sudo make install

Fails at make... Seems the paths are worng for a centos system.. Need to look into makefile /home/anderssandstrom/sources/e3-ecmc_plugin_socketcan/kvaser/socketcan_kvaser_drivers

sudo yum install kernel-devel The sources are at the wrong place.. Sources for wrong kernel..

/lib/modules/3.10.0-1127.el7.x86_64/build

THIS IS A SIDE NOTE for PEAK usb CAN interface !!!

Check if support for PEAK USB

sudo cat /boot/config-3.10.0-1127.el7.x86_64  | grep PEAK
CONFIG_CAN_PEAK_PCI=m
CONFIG_CAN_PEAK_PCIEC=y
CONFIG_CAN_PEAK_USB=m
CONFIG_SND_FIREWIRE_SPEAKERS=m
# CONFIG_SPEAKUP is not set
