I am trying to get nucore running with a Parallel Port on a PCI-card. I also installed a Ubuntu-9 realtime distribution and can use the port from a Java program to control a Pinball 2000 machine, which works very well (using IRQ18, address 0xEC00).
However, the newcore software obviously doesn't recognize the port (message: "No driver board found. Using emulated port").
I traced the problem to a conflicting irq18: IRQ18 is used for uhci_hcd and is not available for the parallel port. dmesg|grep parport tells me:
Code: Select all
[ 43.290470] parport0: PC-style at 0xec00, irq 18 [PCSPP,TRISTATE,EPP]
[ 43.292846] parport0: irq 18 in use, resorting to polled operation
[ 45.387482] lp0: using parport0 (polling).
Code: Select all
partport0: PC-style at 0xec00 irq 18 using FIFO
Thanks
