if you use deii with 8m sdram, change the link address of the uncompress loader,

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,I am sure the FLASH and the SDRAM is no problem ,because i tested the hardware and can run UCOS/2 application and other programs.

the flash(8MB) base address is 0x000000,the sdram(8MB) base address is 0x800000,so i set the zImage load address :0x500000+0x800000=0x0d00000,

and then make ,still has the same problem.

why set the link address offset 0x500000?

thanks

Did you "make linux image" ?

You should set Link address offset for booting to 0x500000, not 0xd00000 .

Kernel config will add up with sdram start.

During nios2-download , what is the load address show up?

try,

nios2-linux-uclibc-objdump -h zImage

it should display, .text start from VMA/LMA 0xd00000 .
