Nios and TCP/IP stack

[jdhar]

I was wondering if anyone had come across a TCP/IP stack for the Original NIOS, not NIOS II? Ideally, I would like to find a stack with a driver for the opencores MAC, but I can only find LWIP for Nios II.

Hello jdhar,

There are some companies which are selling TCP/IP stacks for Nios. But I think you are looking for a free solution, don’t you? I think there is no reason that you can’t use lwip with Nios. “lwip” is C-Code so you can compile it for Nios too.

Bye,

Ya, I'm definitely looking for a free solution - I know lwip is C code, but they don't have an opencores driver, do they? It seems like such a common thing, you would think someone would have done it by now...

Mmh, I think there have been some posts in the www.niosforum.com about that topic.

Ya, they advertise that microtronix pack on that forum pretty heavily - I checked out that driver for OC however. It seems like it could work ,but it seems like it's meant to be built with the LWIP provided by Altera. i think it's the same LWIP, but slightly modified for NIOS II, which is why I'm not sure if it would work or not. I was *hoping* someone had already done this... but given that it's unlikely, I will just offer my dev. board with a big discount for anyone who can port it (already posted on my other thread).

Thanks for your help cube

Do you use any OS for your NIOS II project?
The @ltera FAE recommend ECOS for NIOS II project, as I know, the common ECOS should be networking supported, but I am not sure if the ECOS for NIOS II supports TCP/IP.

eCos is supporting different TCP/IP stacks and different NICs. The configuration tool of eCos is doing a lot of work for the developers but if you want to build up a stable and fast system a lot of knowledge and work is needed. IMO that’s the matter with all operating systems in the embedded world.

as I mentioned, I need a stack for NIOS I, not II - there seems to be quite a bit of support for NIOS II, but the license is quite expensive
