[Xenomai] Peak PCI CAN card RTCAN problem

[Xenomai] Peak PCI CAN card RTCAN problem

[Kronander Klas]

Hi,

I have an installation of ubuntu 12.04 with xenomai 2.5.5.2. This PC is used to communicate with a robot over CAN bus. The CAN card installed on the PC is a dual channel PCI card from PEAK Systems.

I have not been able to use the CAN port at all so far. The device is detected by the systems and the interfaces show up:

cat /proc/rtcan/devices
Name___________ _Baudrate State___ TX_Counter RX_Counter ____Errors
rtcan0          undefined stopped           0          0          0
rtcan1          undefined stopped           0          0          0

but I am unable to change the state from "stopped" to something useful. When I try to reinitialize it tells me that the driver is not loaded:
/usr/xenomai/sbin/rtcanconfig rtcan0 -b 1000000 -c none start
Cannot open RTDM CAN socket. Maybe driver not loaded?

This is confirmed when looking at the loaded modules with lsmod | grep xeno_can_peak_pci, which does not find the relevant module. When I try to load the module with modprobe xeno_can_peak_pci I do not get any error messages, but the module still does not show up when doing lsmod | grep xeno_can_peak_pci.

Looking in the syslog, I can find some information regarding the CAN device, which seemed to have initialized during system startup:

Jun 23 16:20:37 wam-desktop kernel: [    2.105390] RT-Socket-CAN 0.90.2 - (C) 2006 RT-Socket-CAN Development Team

Jun 23 16:20:37 wam-desktop kernel: [    2.110413] rtcan: registered rtcan1

This looks fine right? Yet no driver related to any CAN device is loaded. I am stuck and would greatly appreciate some help for fixing this problem.

Thanks in advance,

Best Regards,
Klas Kronander

Do you have the same issues with xenomai 2.5.6, or even better, xenomai
2.6.0 ?

Hi,

Thanks for the response. I now tried with xenomai version 2.6, I have some progress but it is still not working. 

CAN-problem:
Looking at the syslog, the can card is detected and the rtcan interfaces are set up properly:

Jun 28 11:58:14 wam-desktop kernel: [   11.954476] RT-Socket-CAN 0.90.2 - (C) 2006 RT-Socket-CAN Development Team
Jun 28 11:58:14 wam-desktop kernel: [   11.960228] RTCAN SJA1000 driver initialized
Jun 28 11:58:14 wam-desktop kernel: [   11.967911] PEAK-PCI-CAN: initializing device 001c:0001
Jun 28 11:58:14 wam-desktop kernel: [   11.967920] PEAK-PCI-CAN 0000:05:05.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17
Jun 28 11:58:14 wam-desktop kernel: [   11.972902] PEAK-PCI-CAN: base_addr=f8470000 conf_addr=f8466000 irq=17
Jun 28 11:58:14 wam-desktop kernel: [   11.972914] rtcan: registered rtcan0
Jun 28 11:58:14 wam-desktop kernel: [   11.972920] PEAK-PCI-CAN: base_addr=f849e400 conf_addr=f8466000 irq=17
Jun 28 11:58:14 wam-desktop kernel: [   11.972928] rtcan: registered rtcan1

I now also see the loaded xeno_can_peak_pci driver with lsmod. The status of the can is STOPPED for both ports:
cat /proc/rtcan/devices
Name___________ _Baudrate State___ TX_Counter RX_Counter ____Errors
rtcan0          undefined stopped           0          0          0
rtcan1          undefined stopped           0          0          0

When trying to start rtcan0 I get an error:
/usr/xenomai/sbin/rtcanconfig rtcan0 -b 1000000 -c none start -v 
Cannot open RTDM CAN socket. Maybe driver not loaded?

But the driver IS loaded, so there is another problem. I looked in the syslog and could found this line:

Jun 28 11:58:14 wam-desktop kernel: [   13.017820] Xenomai: xnintr_shirq_handler: IRQ17 not handled. Disabling IRQ line.

I don't know exactly what happens there or why, but it seems that IRQ 17 is disabled? Why and when does this happen?

On IRQ 17 there is the CAN card and two usb controllers. In the rc.local we try to disable the conflicting devices using:

echo -n "0000:00:1a.1" > /sys/bus/pci/drivers/uhci_hcd/unbind
echo -n "0000:00:1d.1" > /sys/bus/pci/drivers/uhci_hcd/unbind

But that does not make any difference. Thankful for any ideas or suggestions on how to proceed!

Thanks in advance,
Klas Kronander

Does the following command work?

/usr/xenomai/sbin/rtcanconfig -b 1000000 -c none start -v rtcan0

Sorry, it should be

Usage: rtcanconfig <can-interface> [Options] [up|down|start|stop|sleep]

Therefore try:

#/usr/xenomai/sbin/rtcanconfig rtcan0 -b 1000000 -v start

Re: [Xenomai] Peak PCI CAN card RTCAN problem

[Kronander Klas]

Hi,

I still get the same error:

mode: start(0x1)
Cannot open RTDM CAN Socket. Maybe Driver not loaded? 

I guess this error message is related to this line in my syslog (?) :

Jun 28 11:58:14 wam-desktop kernel: [   13.017820] Xenomai: xnintr_shirq_handler: IRQ17 not handled. Disabling IRQ line. 

the CAN card is on IRQ 17. 

Thanks,
Klas Kronander

I don't think so. It's an unrelated issue. There is a problem with the
protocol in the first place. Could you please hack "rtcanconfig.c" to
print the return value of rt_dev_socket? Most likely it will return
-EPROTONOSUPPORT.

Wolfgang.

That is a problem (maybe not what causes the issues you have, but 
something you will have to deal with eventually), see:

Hi,

ok did that. The return value from rt_dev_socket is -14. I could not 
find the definition of EPROTONOSUPPORT anywhere, so I don't know if this 
was the expected value?

Thanks,
Klas

Hm, strange. I have to look that up.

To better understand what you are doing... are you using a Xenomai
enabled kernel? Does the latency test work?

Yes, I am using a Xenomai enabled kernel. None of the tests seem to work 
though.

clocktest just gives me zeros. latency does not show anything. I have 
tried to recompile the kernel, still the same result. How find out 
what's wrong? I followed the guidlines on the xenomai website for the 
kernel configuration.

Thanks,
Klas

In the syslog it seems as xenomai was initialized properly. The mesages 
correspond to those on the faq. I also looked through the 
troubleshooting file, nothing there seems to help my case. I will try to 
redo everything again with a different kernel version to see if that 
helps. Any other ideas?

If you are using gcc 4.6.1, please pass CFLAGS=-fno-omit-frame-pointer
on the configure script command line.

Re: [Xenomai] Peak PCI CAN card RTCAN problem

[Kronander Klas]

Hi,

I still have the same issues, with identical results with either of the four different kernel versions and corresponding adeos patches I have tried. 

After having booted into the kernel and installed the user-space xenomai libraries, none of the tests in /usr/xenomai/bin works. If i configure with --enable-dlopen-skins i get the following result from ./usr/xenomai/bin/clocktest:
== Tested clock: 0 (CLOCK_REALTIME)
CPU      ToD offset [us] ToD drift [us/s]      warps max delta [us]
--- -------------------- ---------------- ---------- --------------
  0                  0.0            0.000          0            0.0
  1                  0.0            0.000          0            0.0
  2                  0.0            0.000          0            0.0
  3                  0.0            0.000          0            0.0

If run the xenomai ./configure script without any arguments and then build and install, I get the following message when running ./usr/xenomai/bin/clocktest:
Xenomai Posix skin init: pthread_setschedparam: Function not implemented

As before, looking in the syslog it appears that Xenomai is up and running:
Jul  4 12:33:45 wam-desktop kernel: [    2.089906] I-pipe: Domain Xenomai registered.

Thanks in advance for any ideas or suggestions on finding the issue,
Klas

If you are using gcc 4.6.1, please pass CFLAGS=-fno-omit-frame-pointer
on the configure script command line.

Have you tried to run ./configure CFLAGS="-fno-omit-frame-pointer" as I
already suggested?
