Hello, I can't setup USB/CAN FD to work on Ubuntu in any way, device is detected but no can0, no base or IRQ identification I'm using UBUNTU 18.04, kernel 4.18.0-15-generic:

Code: Select all

Using dmesg | grep pcan :

I suppose I have problem with module verification failed: signature and/or required key missing - tainting kernel ?

After driver reinstall:

Code: Select all

$ sudo rmmod pcan
$ sudo insmod pcan.ko

$ cd ../test
$ ./pcanfdtst rx -b 500k /dev/pcan32

I receive messages on CAN bus:

Code: Select all

 cat /proc/pcan

but when trying to initialize socketCAN it doesn't see any can0 adapter. The only one I see is vcan0:

Code: Select all

ip link show

9: vcan0: <NOARP,UP,LOWER_UP> mtu 72 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/can

I think I got it sorted:

On ubuntu 18 net-tools are missing (no ifconfig). After installing net-tools:

1. go to the peak-linux-driver-8.4 directory and call
2. sudo make uninstall
3. reboot
4. sudo ifconfig -a

I get:

Code: Select all

Hi,

If you want to use the pcan driver with the socket-CAN interface, then you must build it accordingly. Please refer to chapter "4.8 netdev Mode" of our User Manual "PCAN-Driver-Linux_UserMan_eng.pdf" provided in the "Documentation" directory. Moreover, you're advised to install the last version of this pcan driver.

You should first have a look to this page https://www.peak-system.com/fileadmin/m ... /index.htm.
