Hi Kirk, Thanks. I get an ECR of 53. > Once you get an ECR value greater that 127, you can test it with Jon's > diagnostic program or run LinuxCNC. Looks good - I get an ECR of 149. > The 0x0378 address you may see is most often the address for the > motherboard parallel port, with an extended register address of 778 (but > the extended register could have a different address). I see. As far as I know, there isn't a parallel port on the motherboard though. Weird? Alas, I still get a fault: > univstepdiags c030 bus io addr = c030 parport addr 0xc030 Segmentation fault LinuxCNC fails to start with the same message as before.
