[Xenomai] Compatibility of PCAN PCI Express Four Channel

[Xenomai] Compatibility of PCAN PCI Express Four Channel

[Zhe Su]

Dear all,

I am running xenomai 2.6.3 on Ubuntu 12.04, and I would like use a
four-channel PCI express CAN board manufactured by PEAK system. The exact
model name and number are PCAN-PCI Express Four Channel galvanic isolated
IPEH-003040. I am wondering if xenomai 2.6.3 rtcan driver will be
compatible with this board?

Your advice and help will be highly appreciated!

To check whether your board is compatible, get its ids with lspci.

Then look at:
https://git.xenomai.org/xenomai-jro.git/tree/kernel/drivers/can/sja1000/rtcan_peak_pci.c#n73

To see if the pci ids of your card are supported. If they are not,
you may be able to get the driver working for your board by adding
you board's ids to the peak_pci_tbl array, if the board is
compatible with the driver.

The driver is not working properly with for channel card (only two
interfaces are visible).
Long time ago i made a patch for that :

Dear Gilles and Konrad,

Thanks for your reply. As you suggested, I confirmed the ids of
four-channel PCI express CAN board is in the rtcan_peak_pci.c file. I just
got my new four-channel PCI express CAN board yesterday; however, none of
the channel is working on my xenomai.  It did recognize there is a
PEAK-System Device plugged in the PCI express slot, but it is not working
with the can driver. Here are the results of the comparison between a
two-channel PEAK-System PCI CAN board and a four-channel PEAK-System PCI
express CAN board.

lspci -nn
02:00.0 Network controller [0280]: PEAK-System Technik GmbH PCAN-PCI
CAN-Bus controller [001c:0001] (rev 02)
22:00.0 Network controller [0280]: PEAK-System Technik GmbH Device

Any help will be highly appreciated.

Neither of these two commands is showing the pci ids.

Try lspci -n

Re: [Xenomai] Compatibility of PCAN PCI Express Four Channel

[Zhe Su]

Dear Gilles,

Thanks for your prompt reply. In my last email, it already included the pci
ids, shown in the bold letters:

lspci -nn
02:00.0 Network controller [0280]: PEAK-System Technik GmbH PCAN-PCI
CAN-Bus controller *[001c:0001]* (rev 02)
22:00.0 Network controller [0280]: PEAK-System Technik GmbH Device
*[001c:0003]* (rev 02)

001c is the manufacturer id, and 0001 and 0003 is the 2-channel PCI
and 4-channel
PCI express, respectively.

Indeed. Anyway, what is the problem exactly ? "It does not work"
does not give much details.

Please be more specific. What command do you run, what is the result
that makes you think that the drier is not working ?

Well, it would seem the driver does not match your board. Is the
matching done only on vendor id/product id, or are the other ids
used in the driver table ?

[Konrad Banachowicz]

As I wrote earlier the 4 channel card is not supported in
mainline(xenomai) driver.
The patch i mentioned add the support. It should work with latest
xenomai 2.6.x .

Sorry, I just assumed Zhe Su had applied the patch.
