de2 will not start after flashing

[Altera_Forum]

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.
