Hi,
I want to begin with play a little bit with crosstools and ezx-devkit.
But the Link lsb.blogdns.net/ezx-devkit is deed.
Has anyone an idea, where I can get this from?

[Devola]

thanks a lot, donga, I'll try it soon, thanks thanks

Waiting for a native winskin from donga

I 'll trying to hack it soon .. before hard working on my fulltime job on next month



@ilchenko
please try to use my modified of samr7's header, and use my tmakespec (you may need a little modify).

[dehzinho]

hey donga, is it too dificult for you and the developers, to port an ezx app from e680i to a1200 ? does it take too much time ?

[lavelas]

I think the main challange with porting from e680 and similar is that some kind of standard class usage that works fine on e680 fall into seg fault on a1200/E6. Donga, correct me if i'm wrong.

[dehzinho]

does that mean it's impossible ?

[ilchenko]

@donga, I'm sorry, your example is work with Your + Samr7's headers and libraries from phone. Thanks.
