ubuntu server 16.04 driver does not load automatically

[inspire]

Hi,

I try to use the peak can driver with ubuntu server 16.04 but the driver is not loaded automatically. I installed the driver 8.3.1 with and without netdev support without success. The problem is always the same: If I start linux with the USB-CAN Dongle attached, the command "ifconfig -a" does not show any can device. But if comment all lines from the file /etc/modprobe.d/blacklist-peak.conf, plug the dongle in and out, uncomment the lines again and plug the dongle in again, the device is suddenly shown with "ifconfig -a".

The make install command also shows:

Info: Copied 45-pcan.rules to /etc/udev/rules.d.
Info: mainline drivers removed and blacklisted in
/etc/modprobe.d/blacklist-peak.conf
Makefile:507: recipe for target 'install_udev' failed

How can I make linux enable the dongle automatically?

Thanks in advance!

Hi,

if you want to use the NetDev driver interface with the PCAN-USB and Ubuntu 16.04, there is no need to install our peak-linux-driver. To disable the blacklisting of the kernel driver, please call "sudo make uninstall" in the peak-linux-driver-8.3.1 directory, and reboot your system once.

Please also check that you don´t use any USB extension cables or unpowered USB hubs between your PC and the PCAN-USB.

best regards

Michael

Hi Michael,
You are right, without the drivers it works perfectly, thanks!

But if I run candump can0 I got

or sudo ifconfig can0 up

Hi,

You have first to setup the bitrate in the PCAN-USB:

Code: Select all

$ ip link set can0 type can bitrate 500000
