de2 will not start after flashing

Hello everyone,

i know its a common problem, but i cant get it to work.

Altera DE2 with uClinux NOMMU again. Quartus Webedition for Linux.

I want to permanently flash uClinux onto my board, everything works, but after a reset the board is dim and it will not start.

Obviously it dont gets the reset to wake up.

Here is what i did:

I followed

http://www.nioswiki.com/operatingsystems/uclinux/flashprogrammer

I am using DE2_NET example v1.6 from the terasic homepage.

nios2-configure-sof /home/user/nios2-linux/de2_net.sof

cd uClinux-dist/images/

sof2flash --epcs --input=/home/user/nios2-linux/de2_net.sof --output=standard.flash

nios2-flash-programmer --epcs --base=0x00680800 standard.flash

elf2flash --base=0x00000000 --end=0x3fffff --reset=0x0 --input=zImage --output=ext_flash.flash --boot=/opt/altera9.1sp2/nios2eds/components/altera_nios2/boot_loader_cfi.srec

nios2-flash-programmer --base=0x00000000 ext_flash.flash --go

With the --go the board resets and everything works fine.

But no luck after reset.

After another

nios2-configure-sof /home/user/nios2-linux/de2_net.sof

The board boots up without a problem. But i have to do this manually.

I had a look with sopc_builder.

At "more cpu0 settings nios2" it says:

Reset Adress cfi_flash_0 0x0 0x0

Exception Adress sd_ram0 0x0 0x00800000

In make vendor_hwselect i choose:

--- Please select a device to execute kernel from:

(1) sdram_0

Class: altera_avalon_new_sdram_controller

Size: 8388608 bytes

Any ideas? I am stuck.

Thanks and have a nice weekend.
