[Xenomai] Analogy and PCI-6289 issue

[Lopes, Alexandre]

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!

Alexandre

please check

http://git.xenomai.org/xenomai-3.git/tree/kernel/drivers/analogy/national_instruments/pcimio.c#n1055

support for the 6289 (ie 0x70ac) is in the todo list - disabled by the
conditional compilation statement.
since you have the hw, you could enable it and try to get it to work: it
shouldnt be too hard (I dislocated my shoulder last week so Icant provide much
coding support at the moment..maybe in a couple of weeks)

Thank you so much! That should be more than enough. I will try to recompile 
the driver in a few minutes.
I should have checked the source, but just assumed that it had been 
my fault, since the website stated the board was supported (and it appears 
to be in any case).

Wish you a good recovery.
