NiosII IDE to Build old Nios project

Does Somebody knows how to build old software project developed for Nios# 1 in new IDE for Nios# 2? I ask SOPC builder to add legacy software components such as "excalibur.h" file, so I can build ...

jesse, danc

Thanks a lot for such detailed description. I'll try to follow your advices.

The only reason for me to use legacy sdk is in the small size of code footprint of generated software.

I'm building system with TCP/IP network (feat by lan91c111:). And when I use old plugs library I can fit all code to onchip memory of Stratix1S10 device.

I have build such sistem for Nios CPU. So when NiosII was released I try to migrate to all brand new: NiosII CPU, NiosII IDE and lwIP tcp/ip stack realization. But unfortunately code footprint even for standalone lwIP realization is near 250Kb that is ten times bigger that my previous plugs tcp/ip realization (approx 24Kb).

I decide to try to use old sdk but with new CPU and with new tools cause new tools is much more convenient for software development.

So if anyone can give me a pice of advice how to reduce code foot print for standalone lwIP library I will immediately stop to use old sdk.
