Upgrade via Ethernet

Hi Oleg,

i am quit not shure about your target design.

Does ist consist :

FPGA

Flash

SRAM

Ethernet (for example)

and what source of your fpga image (inside Flash oder epcs) ?

Of you have an epcs then you can of course update your epcs via nios, but no fall back option if update is corrupted

if you have the image inside a flash then you need some kind of external configuration device that reads out the image from the flash an stores it into the fpga.

Regards

Michael
