Oh my god. I would like to avoid telling you why it hasnt shown any information when using this command: cat /proc/ioports | grep parport , but i should

Before the reinstall i tryed if i get into linux without the Parallel card, so i took it out.
Then if forgot to put it back.....
I already laugh about my self.

The good news: cat /proc/ioports | grep parport:
c800-c802 : parport0

So, do i understand that everything is okay ?

I hope so much

If "cat /proc/ioports | grep parport" did not output anything, then Linux is not picking up your Parallel port card.

Try re-seating the card in it's slot a few times. Then try the "lspci -v" and look for anything that might be the card, and post what is there.

Thanks Todd for the info. I think you havent read my last post. Just read and laugh

.

Im out with my dog now, but then i will check what happend when i do stepconf with connected drivers etc. Let see if i get the error i got last time when i did it without the parallel card.

Did the Stepnconf test and LinuxCNC opens without errors.
So, i think everything works. Will continue to test and inform you.

So,
i tryed to get one axis (X) to work and Jog it, but nothing happens. Everything is correctly wired up and the AM882 driver does also show no Red (error) light.

I opened the terminal and typed in : sudo lspci -v:
Result (this are only the outputs which had "netmos":

why the I/O ports are disabled ? Is that the problem here?

Hello,
tryed to figure out how to enable the i/o port which are disabled, but with no success. Checked also if Plug n Play OS is activated, but its off. Unfortunately i can do no Pci/Pci-e settings in the bios.

Here are some more outputs:
lsmod | grep parport:
parport_serial 16674 0
parport_pc 21896 2 parport_serial
parport 35208 3 lp,ppdev,parport_pc

** the last line looked like this: parport 35208 3 parport_pc , before i did this:
sudo modprobe lp
sudo modprobe ppdev
sudo modprobe parport_pc

Next command:

cat /proc/ioports | grep parport
c800-c802 : parport0

dmesg | grep parallel
[ 9.788093] ppdev: user-space parallel port driver

I really tried a lot to get it to work and it seems that netmos/moschip 9901 are working chips, so i dont know what i should do right now. I hope the outputs helps to help me

.
Let me know if i can give you more outputs.

Small success (but still no jogging possible:
[disabled] is not anymore showing at the I/O ports at ....

What i have done (output only from the serial / parpor lines)t:
lscpi -n -v

02:00.0 0700: 9710:9912 (prog-if 02 [16550])
	Subsystem: a000:1000

	[virtual] Memory at fcefc000 (32-bit, non-prefetchable) [size=4K]
	Capabilities: <access denied>
	Kernel driver in use: serial

	[virtual] Memory at fcefa000 (32-bit, non-prefetchable) [size=4K]
	Capabilities: <access denied>
	Kernel driver in use: parport_serial

Then:
setpci -d 9710:9912 command=101

pcilib: Cannot open /sys/bus/pci/devices/0000:02:00.2/config
pcilib: Cannot open /sys/bus/pci/devices/0000:02:00.1/config
pcilib: Cannot open /sys/bus/pci/devices/0000:02:00.0/config

Then tryed with sudo:
sudo setpci -d 9710:9912 command=101

got no output, but then i used:
lspci -n -v

02:00.0 0700: 9710:9912 (prog-if 02 [16550])
	Subsystem: a000:1000

	I/O ports at c800 [size=8]
	I/O ports at c480 [size=8]

	[virtual] Memory at fcefa000 (32-bit, non-prefetchable) [size=4K]
	Capabilities: <access denied>
	Kernel driver in use: parport_serial

So, the ports are not anymore disabled.

Then i used this command:
dmesg|grep parport

[    7.564612] parport0: PC-style at 0xc800 (0xc480), irq 7 [PCSPP,TRISTATE]
[    9.785575] lp0: using parport0 (interrupt-driven).
[ 4288.728383] PARPORT: ERROR: linux parport 0 not found
[ 4362.708808] PARPORT: ERROR: linux parport 0 not found
[ 4437.413421] PARPORT: ERROR: linux parport 2 not found
[ 4453.049556] PARPORT: ERROR: linux parport 3 not found
[ 4487.770612] PARPORT: ERROR: linux parport 3 not found

?? Strange... Before setpci i had no PARPORT: ERROR
lsmod | grep parport

parport_serial         16674  0 
parport_pc             21896  2 parport_serial
parport                35208  3 lp,ppdev,parport_pc

I tryed to use 0, 2 and 3 as parport base address, but jogging the X axis did not work. I have only connected the X-axis, not other components. (BOB to LPT (12v supply connected to the BOB and all 3 lights are lightning, when taken off the Parallel cable of the BOB, then the 2 lights from the Relais are not lightning), 80V supply to AM882 Driver, Stepper motor (8 wire, parallel connection= to AM882 driver. Driver shows no Red light, so everything is wired up correctly.

It seems that still something with the parallel card is not right (PARPORT ERROR output from dmesg|grep parport)

I hope this helps.
Sorry, for bombing this thread all the time, but at least you see that i try to fix it by my self...

It looks like lp might be "grabbing" the parport and not letting LinuxCNC have it.

forum.linuxcnc.org/39-pncconf/30720-7i43...parallel-port-errors

Might contain the required info.
As a first step you can try "rmmod lp" then try running LinuxCNC again.
