Honored ContributorYou didn't program the flash at 0x000000 yet. You can program the flash, so that will start after power-on without data blaster download/cable.

The nios2-download will load the zImage to (0x800000 + 0x500000), and start exec at this address, ie 0xd00000. The zImage will uncompress the linux kernel (gziped in zImage) to 0x800000. And start exec at 0x800000.
