[Xenomai] Analogy and PCI-6289 issue

["Lopes, Alexandre" <alexandre.lopes.ext@zeiss.com>]

Hello,

I am currently using Xenomai 3.0 rc4 (3.18.12 Linux Kernel)
and trying to get Analogy to work with the following NI cards:
* PCI-6289
* PCI-6713

>From what I have read, both should be supported by the analogy_ni_pcimio
driver.

The problem is that, while I can get the 6713 to work, I am unable
to get the 6289 to work.

At boot both cards are recognized by Analogy:

[   13.172013] Analogy: MITE: Available NI device IDs: 0x1870 0x70ac

and both show up on the output of lspci

The PCI-6713 works flawlessly.

After running 

analogy_config analogy0 analogy_ni_pcimio 3,3

I get:

cat 00-analogy_ni_pcimio

but for the 6289

sudo analogy_config analogy1 analogy_ni_pcimio 3,2

returns

analogy_config: a4l_attach(analogy_ni_pcimio) failed err=-1
analogy_config: check the procfs information:
 - analogy devices: /proc/analogy/devices
 - analogy drivers: /proc/analogy/drivers
 
and in dmesg
 
[1792.306659] Analogy: a4l_assign_driver: call(drv->attach) failed (ret=-2)

I have already tried to swap pci slots, to use only one card, to omit the driver parameters
etc. and the end result is always the same: I can attach the driver to the 6713 but not to
the 6289.

Could anyone help me shed some light on the issue?

Thanks!
