Hi there,
I can't manage to build the peak linux driver.
Can you please help me on this one ?

Hi,

please send an email to our support email address telling us the serial number of your PCAN hardware. You need a patch for using the peak-linux-driver-8.16 with such a recent kernel version 6.5.x.

regards

Michael

Hi Michael,
Thank you very for your help.
Just a stupid question. Do I need to install the driver if I want to use the pcan ethernet gateway DR or I may be able to communicate with the gateway using simple Linux TCP socket ?
Many thanks for your help.
Regards,
Olivier

Hi Olivier,

the PCAN-Ethernet Gateway is not supported by our peak-linux-driver. In that case you don't need that driver at all. You can use Linux sockets to communicate with the PCAN-Ethernet Gateway. See Developer Documentation for more details:

Hi Michael, here we have the same issue, could you please share the patch to let us compile the peak-linux-driver-8.16.0 driver ?

We want to use the PCAN basic API with Python.

You'll find below some commands if it could help you to debug.

Hello,

I'm running into exactly the same issue as YoanEyeLights after updating to the 6.5 kernel.

Could you pelase send me the patch as well (or make it publicly available, since it will most likely affect more people after the update to the 6.5 kernel was recently released)?

Thanks in advance and best regards,
Franz
