Hi,

which kernel version do you use? Please post output of uname -a. Those PCAN-PCIe FD cards will be supported by the kernel since 4.12. If you use an older kernel, please install our peak-linux-driver-8.x with Netdev support.

regards

Hello Michael,
my kernel version is : 4.4.92-18.36-default

Here i have 2 questions?

1) is it possible to compile single kernel module (peak_pci) of 4.12+. and replace it in present existing kernel (4.4.92) because i don't want to change my existing kernel (4.4.92) ??

2) I have downloaded Peak-linux-driver-8.4.0 from your site and compiled and installed it:-

driver is enabled and working fine :
I have verified with this command: cat /proc/pcan

Code: Select all

So could you please let me know how to enable "pcan" Netdev support to get can0 and can1 interfaces???

Hi,

here the answers to your questions:

1. yes, this should be possible. We could generate an out-of-tree driver for you, which you can install on your system with kernel 4.4. Please contact us by email, use our linux email address.

2. please rebuild and reload the driver again for socketcan (make NET=NETDEV_SUPPORT), see driver manual for more details. Please use latest driver version 8.5.1.

regards

Michael

Dear Michael,

As per your guidance i have downloaded latest driver [Driver Download Version 8.5.1 (27.10.2017)] when i try to build it with netdev support as per your manual.

I get below error ???

Code: Select all

linux-qfs6:/home/exxpert/Desktop/peak_driver/peak-linux-driver-8.5.1 # ls
Documentation       Makefile     driver        lib          test
linux-qfs6:/home/exxpert/Desktop/peak_driver/peak-linux-driver-8.5.1 # make –C driver NET=NETDEV_SUPPORT
make: *** No rule to make target '–C'.  Stop.
linux-qfs6:/home/exxpert/Desktop/peak_driver/peak-linux-driver-8.5.1 # 

Could you please help me how to solve this error??

Hi,

please try again, and follow my steps:

goto the peak-linux-driver-8.5.1 directory and type:

sudo rmmod pcan
make clean
make NET=NETDEV_SUPPORT
sudo make install
sudo modprobe pcan
