Re: [Linux-gpib-general] NI PCMCIA Card

[Mitchell F. <mit...@ya...>]

Compiling my own kernel fixed that problem. With the modules inserted,
when I run ibtest for the first time it segfaults. I tried running it
under gdb after compiling with the "-g" option, but it says the program
exits. Running ibtest a second time, it stops at "trying to open pad =
12 on /dev/gpib0 ...", I can ctrl-c it.

Ah. Is there an older version that works with 2.4.x kernels and has a
VFS interface?

Maybe I should try and read out the FPGA's EEPROM? (just joking...)

The only thing that could cause the init_module to fail is if the release
code for your pcmcia modules don't match the value in the header files you
compiled against.  Apparently, this has been a problem with Suse and
RedHat in the past.  You can disable the check ( it's in the
init_ni_gpib_cs() function in drivers/tnt4882/tnt4882_cs.c ) or compile
your own kernel so you know the release code is consistent.

[Linux-gpib-general] Documentation

[Major A <an...@us...>]

Hi,

I just downloaded linux-gpib-3.1.4 and failed to get anything
working. This may be due to the card not being supported, or due to my
stupidity, or both. Unfortunately, the documentation shipped with the
package seems to be outdated, I couldn't find ibchk and the other
utilities mentioned, and no such modules as gpib0.o etc. are built.

I did a modprobe on the driver I believe I need (cec-gpib), which then
printed an initialization message in the system log. Now there's some
confusion as to what device files I need -- I tried various
major/minor combinations (c 31 0, c 31 17, c 160 0, c 160 17), with no
success: only c 160 0 seems to have a kernel driver behind it, but it
says "invalid argument" to anything I do. I'd like to use the VFS
interface, so I didn't bother setting up a config file etc.

Another potential problem is the card: it's an HP PCI card and has two
chips on it: a PLX9050 (which is also used by cards supported by
cec-gpib and ines-gpib, apparently), and a Xilinx FPGA. I only hope
that it's compatible to one of the other PCI cards... This is the
output of lspci -v:

01:0a.0 Communication controller: PLX Technology, Inc. PCI <-> IOBus Bridge (rev 01)
        Subsystem: Hewlett-Packard Company: Unknown device 10b0

        Memory at ff8fe400 (32-bit, non-prefetchable) [size=16]

Anyone recognize this?

Before I forget: I use devfs, is there any support for it in
linux-gpib? It would be nice to have it, so I wouldn't have to create
device files "by hand".

Any help would be much appreciated, in particular the VFS interface
stuff.

You want the pc2-gpib module for an isa cec card, not the cec-gpib module
(which is for the pci cec card).  Also, there might be some problems with
pc2 support in the last release although it seems to be fixed in the
current cvs head.

Okay, the cvs should work now.  It turns out debian's dialog program (I
use debian) is actually cdialog which works slightly differently than the
original.  Also, the config scripts should be able to use whiptail now too
instead of dialog.

When I run make initally (and it invokes util/Setup), after I press

quits and prints:

The laptop is running a clean install of SuSe 7.3. The same installer
works fine on my desktop (Debian Woody).

You may be having an ioport conflict.  In IIA mode, the pcII/IIA actually
provides 16 ioports instead of the 8 used by a real IIA.  The extra
ioports are used to access the extra capabilities of the nat4882 chip.
They are not allocated by the driver, and if something else is writing to
them it could put the nat4882 into an unusable state.  The extra ioports
come after the first 8 with the same spacing of 0x400.  I suppose I could
add a new interface for 'pcII/IIA in IIA mode' that allocates all 16
ioports so a conflict will show up right away.  Yes, I should do that.

Frank

Re: [Linux-gpib-general] PCIIA problem

No. The PCII/PCIIA card works only in PCII mode. In PCIIA mode, there
is an error about command bytes, identical to the one discussed
previously on the list. I can double check my settings, but I'm pretty
sure I had everything right. The PCII/PCIIA card didn't work at all

Do you mean rather it works in pc2a mode but not in pc2 mode?  Also, did

The pc2a card works with dma. The pc2/pc2a card works in pc2 mode. In

The first thing I need are the manufacurer/device id numbers.  They should

Have you read the section of the INSTALL file where it talks about setting

[Linux-gpib-general] make fails ....

[Ulhas V. <ul...@ti...>]

hi frank (and others on the list),

i am trying to install the code (ver 3.1.4) on rh 7.1 running on kernel
2.4.2-2 and gcc 2.96. The hardware is NI PCII card with addr 0x2b8, irq=7,
dma=0.  the "make config" seems to doing fine. i do see a gpib.conf
created in /etc with correct hardware settings.

however, make config fails. i have put the screen dump in the attchment
since i failed to understand why this should happen. it reports the
problems with header files in the kernel source. could you please help me
through this? i know the attachment is really big, but i thought it to be
better to provide all the info i could.

thanks,

ulhas

I am happy to do any testing with the hardware I can
get my hands on.

Just tell me what I have to do :)

Thanks,
Mitchell
