PCAN-miniPCIe FD driver for Linux arm64/aarch64 architecture

[M.Heidemann]

With a PCAN-PCIe you should not need to install the driver at all,
just uninstall the driver package and reboot the machine.

The maniline kernel 4.9 already includes the drivers for PCAN-PCIe.

Once everythin is uninstalled and the PC rebooted, check via

Code: Select all

ip link ls

if the device comes up with channels as "can0, can1, can2" etc.

Does this look fine (before I crash the system again)?

Hello,

Did you check if you have the driver included in your kernel yet?

uninstall the driver and delete its remains.

reboot your machine.

Check if your can channels show up via

Code: Select all

ip link ls

they should be coming up as can0, can1, etc

Your kernel 4.9 includes driver for PCAN-PCI already, no need
to install the one from the package.

Hello,

Could you please just check:

Hello,

Thank you for confirming this.

By default the drivers for PCAN-PCI should be included in the kernel,
seems like your kernel-config excluded them.

Code: Select all

cat /proc/config.gz | egrep PEAK_     
# CONFIG_CAN_PEAK_PCI is not set
CONFIG_CAN_PEAK_USB=m

In this case you'll have to change the config for your kernel and recompile it to include
the necessary drivers for PCAN-PCI.

Best Regards

Marvin
