need help about cfi on board

Sorry to post this here, cause my aim is to run a uclinux on board. I started without the pcb netlist first, it can process and generate the system, but in that way, flash cannot be tested by the memtest.c from niosII examples and i cannot use the flash programmer.

please be patient with my words cause i am really very eager for your help.

i am trying to do something with the problem as follows:

1)i created a board of cyclone2c35(the develop board model provided in the SOPC builer) and compile it. pass.

2)in the board description part, i changed it to my own nelist and definition of flash etc. in the last step of board description, i changed the board name to a new one. and click finish.

3)Back to the SOPC builder, i selected the board i just defined. in this way, all the components can be complied correctly.

with this system, when running the NIOSII IDE for programs, only the helloled.c can be excuted correctly(i can see the leds changing), but the helloworld, memtest do not have feed backs after being downloaded in the cpu.

is it possible that the problem is in the ptf file? or whether can i run a uclinux without the netlist?

thang you very much again.
