it may be

1. problem of sdram timing or hardware, you should run some sdram test or hello on ide/hal .

2. byteblaster is not stable, altera recommend usb blaster for nios2 download.

try add termination to jtag signal on your board.

You have 8MB sdram,

you should set boot loader offset to 5M in kernel config. http://nioswiki.jot.com/wikihome/operating...nux/linuxconfig (http://nioswiki.jot.com/wikihome/operatingsystems/%c2%b5clinux/linuxconfig)

cd ~/uClinux-dist-test

make menuconfig

Kernel/Library/Defaults Selection --->

(linux-2.6.x) Kernel Version

(None) Libc Version

[ ] Default all settings (lose changes)

[*] Customize Kernel Settings

[ ] Customize Vendor/User Settings

[ ] Update Default Vendor Settings

Then <exit> <exit> <yes>

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.[/b]

Then "make" again.
