Re: Newlib port for new architecture

[Sebastian Huber <sebastian dot huber at embedded-brains dot de>]

Hello Varun,

I would not use a Windows host to do this work. Its probably much times 
faster if you do this on a Linux machine. I would also use a Git clone 
of Newlib to do the development.

It seems you need a native GCC installed. I would really use a Linux 
machine, just select the C/C++/kernel development packages and 
everything should be available.
