Why is IPv6 in RedBoot not possible?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]




We're adding IPv6 support to our eCos-based products.  The basic IPv6
support in the "full-up" application code is working fine (at least
with static and link-local addressing).  The next big question mark is
RedBoot.

I need to either add IPv6 support to RedBoot or make some basic
changes to the way our product works (specifically how the application
is updated in the field).  Many years back Andrew Lunn stated that
IPv6 support in RedBoot was not possibleP

My question is why?

I realize it might be a fair amount of work to implement some sort of
IPv6 support in RedBoot, but I'm wondering what would make it "not
possible".
