rtapi_app: caught signal 11 - dumping core

I did type
sudo lspci -v
did i?
-
The port is there and working, but there is no info on capabilities as you did not use sudo.
The port address to type into the wizard is 0xe000

Yes you did type sudo lspci -v, I think I did too.
I put the address in the wizard for the parallel port.
I get the same no par port registered error but with the new address 0xe000.
Maybe I should get a new pci parallel port card.

That's with sudo for sure.

Last post is with sudo, the previous was not as can be seen by "permission denied" for capabilities.
Did you try setting the address and running LinuxCNC?

You are correct.  I forgot to sudo the first time.
I did try to run LinuxCNC with the new address.
I got the same error with the new address.
The demo runs.  Computer is not connected to the mill so I don't know if signals are going to the port.
Thanks for your assistance. 

 

It is not an error as noted on the warning, well not always, so you do need to test on a machine or use a DVM to check the output pins on the parallel port connector.
