PCIe Card issue / deactivate when LinuxCNC starts

Hello,

I'm new to this forum and Linux... And directly start with an issue I cannot solve.

I started with an old PC which has an onboard parallel port. installing Linux and LinuxCNC worked well. As well setup the machine worked well and it's moving :) But the jitter times are ~95k ns...

So I decided to use a newer machine... This had no parallel port so I bought this PCIe card: www.logilink.org/Produkte_LogiLink/Inter...iell_1x_Parallel.htm

with lspci -vv I got following result:

(here in that pictures is written "disabled" -> which is not when I start the pc)

Installing driver seems not necessary so I inserted to HAL file "0x2000 out 0x2010 in"

When I start LinuxCNC I hear some switching in the Machine controller for a second -> seems there comes something in through parallel port. But I can not control my machine, nothing happens.

When I then repeat lspci - vv command I got the reading as shown in the picture above. The card seems to be disabled.

I cannot understand why. Do you have any idea?

Regards

Christoph

Does it have 1 or 2 parallel ports ?
If one, use only 1 of the addresses, not both.
BTW, you have to restart the PC if you set the wrong address, othervise it does not work.

It just have one parallel port.

So I need to write "0x2010 out" in the HAL file or w/o the out?

Thanks

Yes, try that, if it does not work put the 0x2000, reboot and test again.

I tried both with restart in between but no reaction from the maschine.

Here is what my HAL file looks like:


What else can I try?

Kind regards
Christoph

That is a PCI-E card with MosChip controller, i have use plenty of PCI cards with MosChip devices, never had a single issue.
Can you try:
loadrt hal_parport cfg="0 out"
one thing i did notice on lspci is that driver in use is parport_serial, but i have never had that, just parport, and yes most of them had 1 parallel and 2 serial ports.

I've tried as well with "0" but doesn't work...

I've bought this crad: www.amazon.de/gp/product/B007F36WRU

In the HAL setting with "0x2010" all runs perfect :) Thanks a lot!
