Receivetest and cat /dev/pcan32 does not work

[dungcoph]

Hi,

I am instlling driver for PCAN-USB.
When I run cat /proc/pcan I have

When I run cat /dev/pcan32, it shows nothing. My terminal run in infinitive process and the light of the PCAN-USB blink.
When I run receivetest -f=/dev/pcan32, I have

Code: Select all

receivetest Version "Release_20090203_n"  (http://www.peak-system.com)

receivetest: device node="dev/pcan32"
             Only standard frames are accepted, init with 500 kbit/sec.
receivetest: can't open dev/pcan32
receivetest: finished (2).

What is the problem with the driver?

Thank you very much.

Hi,

can your please test again, using the latest 7.14 driver. Which kernel version do you use?

If the problem also exists with newer driver version, please build a debug driver and send us the relevant outputs of dmesg.

regards

Michael

BTW: this topic should be placed/removed in the Linux driver section. Done (MG)

Hi,

My kernel version is 3.11.0-15-generic.
I try to uninstall the 7.11 version to install 7.14 but the command "make uninstall" does not work.

Hi,

please call the make uninstall in the peak-linux-driver7.xx directory, not in the \driver directory.

To load the new driver you have to remove the old driver from the system before: rmmod pcan

Hi,

I call the make unsintall in the peak-linux-driver-7.11 directory, not in the \driver directory.
This is the command and the error.

Hi,

you must have root privileges to call make install or make uninstall!

Try sudo make uninstall, when you have a debian based system.

Hi,

I reinstall the driver 7.14 but the errors are still before.

My kernel version is 3.11.0-15-generic.

When I run cat /proc/pcan, I have

Hi,

"/" is missing in front of dev.

Try receivetest -f=/dev/pcan32
