Hi all,

I'm using cycloneIII starter board and i want to execute uclinux from the ssram or parallel flash instead ddr so when i build the zImage i choose ssram or extern flash (parallel flash).

I have the same error when i download the zImage

    I have the same problem,booting from ext_flash(nios2 cpu reset vector),executing from the ssram(nios2 cpu exception vector),the uclinux is halted by using nios2-terminal when the the zImage.flash has been downloaded by the nios2-flash-programmer command to ext_flash successfully!

    I/m sure that the nios2 cpu core works fine!
