Rowley Under Linux Accessing the Parallel Port

Development Boards MicroMod
1

I have an MSP FET debugger (parallel). I have selected the /dev/lp0 parallel port. When I try to connect I get a “Device or Resource Busy” error.

Any Linux experts out there? How do I connect to the parallel port under Linux?

Thanks

The obvious question: did you try to run it as the root user? (if it works as root, it’s probably a permission problem).

Update:

I have done the folowing:

mknod /dev/parport0 c 99 0 -m 666

and

chmod 777 /dev/parport0

now when I try to connect I get a “parallel port already in use” error.

Thanks

I tried running crossstudio as root, same result. :frowning:

I checked the “allow port sharing” box in crossworks and it works.

Thanks
