Hi all,
Finally finishing up the new shop build, and working on firing up the
machinery.
I've got asaw beveller powered by LinuxCNC (not sure of the version,
machine is in the shop) running on Ubuntu 10.04 LTS. Yeah, Iknow it's
elderly, but had been running fine before I fired it up recently.
It's got an mpg pendant, c22 interface card, and a second parallel
port. Last time powered up before the move and the machine was put in
storage, the mpg worked great. I got the machine into the shop,
connected everything up, and it all works except thependant
operations. I've replaced the parallel port card so far, with a new
one, a 9865 chipped card.
Fired up the computer, did an lspci -v and got the address of the
card, ccf0. Replaced that port number for the old on in the hal file,
and fired up linuxcnc. Still nothing. Started doing a
littlescouting around the system, and ran ppdiag. Only the mobo
parport, parport0 at 0x378 shows up. Did a 'dmesg | grep par' and no
second parport shows up. I then cd'd to the /dev directory, and
there's only parport0 listed.
Is there something I need to do to get the second parport registered
in the /dev directory so that the OS can see the second parallel port
card? Or am I missing something obvious?
If you get the lp driver to connect to the port, then it will probably
show up in /dev, but that is NOT what you want to do for LinuxCNC. As
long as the card actually responds to the address you think it is at,
then the various RT and usermode drivers of LinuxCNC OUGHT to be able
to command it. If they can't, then there may be something wrong with
the card. Is ccf0 the only address that shows up for that card?

Jon,
Doesn't it still need a devlink in the /dev folder? The device parport0
shows up there. Neither one of the cards, either the old one or the new
one, show up using ppdiag or ptest (the hal script for testing parallel
ports). Running ppdiag shows only one card, the one on the mobo. It
shows neither the old card or the new. Running ptest it fails when it
tries to load a parport.1 read. According to lspci, I've got ccf0 and
ccf8 to play with. And yes, I know I don't want the regular lp driver
to be used.
Thanks for helping out.
Mark
