PCAN driver crash without any change in system

[szhuo]

Hi I am a master student working on a project with PCAN USB. I managed to make everything working. and with out any change in driver section the PCAN driver just stopped working and it's really urgent for my project submission. I really wish anyone who can help me with this driver.


this is the error i received from the terminal

Code: Select all

$ sudo modprobe pcan
modprobe: ERROR: ../libkmod/libkmod-module.c:832 kmod_module_insert_module() could not find module by name='pcan'
modprobe: ERROR: could not insert 'pcan': Unknown symbol in module, or unknown parameter (see dmesg)
modprobe: ERROR: ../libkmod/libkmod-module.c:977 command_do() Error running install command for pcan
modprobe: ERROR: could not insert 'pcan': Operation not permitted

it's been working for a long time. and today it just keep send error message after 5 seconds of running to my ROS system. and it is stopped working completely once i restarted my computer.

Hi,

please tell us which driver version and kernel version you are using. Please note that you have to rebuild the driver with each kernel update. What I see is no driver crash, it is just not loadable due to wrong configuration (kernel change etc.).

Hi Michael.

My driver version should be 7.15. It’s the one works with Barrett Hand Ros Package.
my kernel verison as displayed
@T430:~$ uname -a
Linux T430 4.15.0-32-generic #35~16.04.1-Ubuntu SMP Fri Aug 10 21:54:34 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

I am pretty new to Linux.
Could you please teach me how to rebuild driver again? I am on a pretty urgent project and due submition is tomorrow.

Thanks so much for your help. Really appreciate that.

Hey Michael:

I was checking on the usr/src folder, it appears

Code: Select all

bbswitch-0.8                     linux-headers-4.15.0-32-generic
gmock                            linux-headers-4.4.0-133
gtest                            linux-headers-4.4.0-133-generic

linux-headers-4.13.0-45-generic  uvcvideo-1.1.1-3-realsense
linux-headers-4.15.0-32

i am not sure is that a kernel update from 4.4 to 4.15 which cause the configuration error. and I try to install the latest Peak-linux-driver-8.15 which appears

Code: Select all

and my kernel version is

Hi,

yes, please make and install latest version 8.6 of our peak-linux-driver (8.15 is future.... )

BTW: when like to use SocketCAN, there is no need to install our peak-linux-driver. Your kernel version 4.15 already has a kernel driver for PCAN-USB included.

Michael
