Analogy driver problem after running rtxi install script

[david-hofmann]

Basic Information:

RTXI Version: 2.0 Installed from Live CD?: No, cloned from git repos PC: Dell OptiPlex-7040 kernel: 3.18.20-xenomai-2.6-2.6.5

Error Description:

What happened? After running the install_rtxi script I get the following message:

-----> RTXI intallation successful.
-----> Putting things into place.
-----> Load analogy driver with systemd
Job for rtxi_load_analogy.service failed because the control process exited with error code. See "systemctl status rtxi_load_analogy.service" and "journalctl -xe" for details.

When running the suggested commands I get: systemctl status rtxi_load_analogy.service

I am stuck. I attempted to recompile the kernel and RTXI but error persists.

Any idea on how to proceed from here? Please let me know what additional information about my system could be helpful.

Thank you very much! David

Let's try to load the driver manually.

1. Please run the following in the command line:

sudo /usr/xenomai/sbin/analogy_config analogy0 analogy_ni_pcimio

If that does not work...

2. Please type lspci -vvv at the command line and find the entry that has the information for your DAQ. It should look something like this:

04:01.0 Unassigned class [ff00]: National Instruments PCI-6259 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV+ VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx- Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 64, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 17 Region 0: Memory at dfafe000 (32-bit, non-prefetchable) [size=4K] Region 1: Memory at dfaff000 (32-bit, non-prefetchable) [size=4K] Kernel driver in use: analogy_mite

The line of interest is:

04:01.0 Unassigned class [ff00]: National Instruments PCI-6259

This tells us the bus address for the DAQ. In this case, the PCI bus address is 0x4 and the specific slot is 1. Once you have this information, please try:

sudo /usr/xenomai/sbin/analogy_config analogy0 analogy_ni_pcimio <bus>,<slot> (in this case it would be 0x4,1).

Hi Yogi, thanks for advice.

1. the console output is only: Killed

2. lspci -vvv gives:

   05:00.0 Unassigned class [ff00]: National Instruments PCIe-6251
   Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx-
   Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
   Latency: 32
   Interrupt: pin A routed to IRQ 18
   Region 0: Memory at f7001000 (32-bit, non-prefetchable) [size=4K]
   Region 1: Memory at f7000000 (32-bit, non-prefetchable) [size=4K]
   Kernel driver in use: ni_pcimio
   Kernel modules: ni_pcimio

   Thus I ran: sudo /usr/xenomai/sbin/analogy_config analogy0 analogy_ni_pcimio 0x5, 0 Again the output on the console is: Killed

I have the same problem but I think it was because I don't have the acquisition board connected to my system. What acquisition board are you using ?

[yapatel]

Yes, analogy_config will throw an error if there is no compatible DAQ on board. Compatible DAQs can be found here.
