Flash Programmer!

Hi,hippo

I following WiKiHome's "Flash Programmer Guide" try out flash.

I have to test the new kerenl image with nios2-download.

Don't run nios2-terminal, use Hyper-terminal on Windows.

Make sure it runs correctly over the RS-232C COM port.

It'sOK!

But when i programmer image on EPCS flash,than power up my Hyper-terminal message has no any message.

What's problem?

I make sure "sof file" it already program on EPCS flash.

I have a doubt, when i want to program "sof on EPCS flash" and "image on CFI flash" how to select "reset address"?

Can you give me some hint?

PS: my dev board is DE2.

Thank you very much!

NiosQ

    Hi NIOSQ:

    You have to select your reset addres in SOPC Builder when building the NIOS system. There you must set it to point to CFI flash.

    I hope this helps,

    Hi,luisalba

    Thank you for your reply.

    I look "nios2_systems.h" found my EPCS flash can uses space only 800KB,so I thank the size is to small , my build "sof file is 310KB" and "image file is 1300KB".

    Anyone know howe to increase EPCS flash size?
