As you notice, the make program enters directory home/faye/uClinux-dist-test/linux-2.6.x and runs hwselect from there, so that&#39;s where the ptf needs to be. Copy the ptf there, or give the absolute address of the ptf, something like SYSPTF=/home/faye/uClinux-dist-test/nios_clk100.ptf, or like hippo said, ~/project/nios_clk100.ptf.

Q2: Why I can open anthor PTF file in uClinux-dist-test with no path?
