No respone when running uClinux in NiosII SDKshell

Hello,

I did not find any file like standard.ptf in the package with Nios II.

Instead for every development board [eg. 1c20,1s10,1s40,2s60 etc], there is separate std_board.ptf file, so in that way, it is Std_1S10, and I used this.

When Nios is installed: They are at:

\altera\kits\nios2\examples\verilog\niosII_stratix_1s10\standard\std_1s10.ptf

\altera\kits\nios2\examples\verilog\niosII_stratix_1s40\standard\std_1s40.ptf

..... etc.

Can you please tell me, in architectural point of view, How these ".ptf" and ".sof " files are related?

And if I have my specific ".sof" file for my FPGA Design http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/huh.gif , how can I know which ".ptf" need to be included, if both of these are to be related.

Regards,
