to hippo:

because the address of any devices on nios is not certain,so we need the .ptf file which come from the sopcbuilder for building the uclinux,i think i can find something about the .ptf file in the ucliux source.

could you understand me?

thank you very much!!

The io ports address is generated from ptf file, in the hwselect perl script.

We run "make vendor_hwselect SYSPTF=your_ptf_path" in uClinux-dist, (or make hwselect in the kernel tree).

The port definition will be created in linux-2.6.x/include/nios2_system.h .
