DE2 TryOutuClinux

Hi all,

I am trying to load zImage_de2_net on to the DE2 board. I have used the DE2_NET.sof to configure the hardware. All goes well untill I run the image using the nios2-download -g zimage_de2_net command. After programming, the nios shell reports that verification failed at an address that appears to be VGA subsystem. I do not have a SD card on the board yet. Could that be the problem?

Thanks everybody!

    For the DE2 kernel config question,

    you should start with the default from uClinux-dist with latest nios2 patches.

    After you have successful boot of uClinux, you can add others step by step,

    eg, DM9000 for ether net. You should enable only what you need, or the kernel will get bigger.

    The DE2 has only 8MB memory.
