hello,

i' ve implemented a web server in the fpga 1c20 in my university. the university closes my ip obtained by dhcp after 24 hours working. i don't know why. so, i need to restart my system after 24 hours working.

how can i implement a reset software not hardware?

and, if i init again the twip stack, can it work out?

thank you

I suspect a less drastic, and less hacky, approach than resetting your system is to enhance your DHCP software to support renewing addresses. The RFC is http://www.faqs.org/rfcs/rfc2131.html (http://www.faqs.org/rfcs/rfc2131.html). It&#39;s relatively straightforward See section 4.4., but basically you need a timer T1 and when this expires you send a DHCPREQUEST
