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?
