PCAN-miniPCIe on Ubuntu 16.04

[pappit]

Hi,
I tried to install new card into our Ubuntu system .
First I tried with peak_pci and because it didn't work I installed the peak-linux-driver-8.8.0.
None of them bring up good result.
My op system is: Linux 4.4.0-142-generic #168-Ubuntu SMP Wed Jan 16 21:00:45 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
My card is: IPEH-003049

Code: Select all

$ dmesg | grep pcan:
[ 15.190715] pcan: loading out-of-tree module taints kernel.
[ 15.190764] pcan: module verification failed: signature and/or required key missing - tainting kernel

Any help appreciated!

Hi,

please post output of cat /proc/pcan. When you want to work with the SocketCAN interface, there is no need to install the peak-linux-driver. The kernel 4.4 already has a netdev driver for the IPEH-003049 included. You will see canX devcies with ip link ls (uninstall peak-linux driver and reboot your system once, so that the kernel driver will be loaded again)

Hi Michael,

Thanks for your reply.

As you have seen in my original post:

Code: Select all

$ cat /proc/pcan:
*------------- PEAK-System CAN interfaces (http://www.peak-system.com) -------------
*------------- Release_20190412_n (8.8.0) Jun 20 2019 13:51:51 --------------
*---------- [mod] [isa] [pci] [pec] [dng] [par] [usb] [pcc] [net] -----------
*--------------------- 0 interfaces @ major 245 found -----------------------
*n -type- -ndev- --base-- irq --btr- --read-- --write- --irqs-- -errors- status

No device visible.

After the uninstall and reboot:

Code: Select all

$ip link ls
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

    link/ether 00:07:32:5e:0a:c5 brd ff:ff:ff:ff:ff:ff

Any idea?

Hi,

looks like the card is not detected in your Linux system. Please post output of lspci. Please note that our PCAN-miniPCIe cards are real PCIe devices, and will not work in miniPCIe slots which only supports USB.

Hi Michael,

Our motherboard is: EMB-H110B-A10-HH-K

In the manual at the connectors section I found the following:
18. Full / Half size Mini Card (mSATA) (MINICARD2)
Half size Mini Card (PCIe+USB) (MINICARD1)

Does it mean that we only can use half size mini card if we want peak_pci module to work?

Best Regards,
Tamas

Hi,

no PCAN-miniPCIe card detected by lspci, looks like your board don't offer PCIe on the slot where you have insert the PCAN-miniPCIe card. Please contact your board manufacturer for support.
