what is the program address displayed in nios2-download?

if the size of your sdram is smaller that 16mb, eg deii with 8mb sdram, change the link address of the uncompress loader to 5m,

processor type and features-->(0x00500000) link address offset for booting.

the zimage load address is ( your sdram base address + link address offset ) . the zimage boot loader does not relocate itself.

Thanks for your reply.

the program address displayed in nios2-download is 0x00000200,I don&#39;t know why it is,because the sdram address is 0x00000020.

the link address offset is 0x00800000,that my cfi flash address,should I change it lower?

And should I change the reset address to the SDRAM in the SOPC Builder?

I user the DE2_NET project in the DE2 demostration,QuartusII 5.1 vesion.

Look forward to your reply again.
