A problem of programming flash...

Now I could see the flash programmer in the NiosII IDE

indeed work,because I see something like this while programming:

--------------------------------------------------------------------

Pre-Reading 85KBytes of data from U15:

|----.----+----.----|

********************* (31.454 sec).

Aug 2, 2005 6:51:09 PM - (??) nios2-flash-programmer: Success. Zero

bytes writt

en to U15-

(because device matched contents of For_UP3.flash)

Aug 2, 2005 6:51:09 PM - (??) nios2-flash-programmer: Flash

programming complete

---------------------------------------------------------------------

However,there comes out some new message

after above like this::

-----------------------------------

Aug 2, 2005 6:51:10 PM - (??) nios2-flash-programmer:

Input file empty--no data

to program into flash. Exiting.

Aug 2, 2005 6:51:11 PM - (??) nios2-flash-programmer

: SOF-download skipped.

Aug 2, 2005 6:51:14 PM - (??) nios2-flash-programmer

: Flash file is too large to

fit in flash memory

-----------------------------------

But at then what the design I wanted to program into

the Flash is a "Hello_World" project template,perhaps

the smallest design of all.

So how could this file be so large that cannot be

programmed into the Flash chip,whose size is 2M ?

Besides,I tried to program some other template

projects into the Flash chip,but the message

were all the same as above indicating they were

too large to program.

Could anyone tell me why this happen?

Thanks in advance!
