Installing or upgrading cygwin for nios2 5.0

Hi tns1,

> I'd like to upgrade the version of cygwin that came with nios2 5.0. Is this possible?

Not sure. I have some problems when I try to mix the environments. I can use the

nios2 binutils, gcc, etc. without problems when building u-boot for example. However,

u-boot is completely self-contained (no HAL, uses its own crt0, etc).

So far I haven't mustered the time or energy to really dig into this -- since I have

cygwin X alongside the Nios II environment just for the X ... I'm a gnome junky ;-)

But again, nios2-elf-xxx work fine under the alternate cygwin (and I can at least

get some other tools to execute with --help option). I'm pretty sure you could get

things working given you can setup the proper environment variables an paths.

I'm using CYGWIN_NT-5.1 1.5.18(0.132/4/2) 2005-07-02 20:30 i686 alongside of

Nios II 5.0 without any problems (yet) -- it's just the latest from cygwin.org.
