[openrisc] Re: OR1K Linker

["Damjan Lampret" <lampret@opencores.org>]

Hi Steve,

most of the problems for OR1K (instruction set OR32) have been fixed. But
these fixes are only available in CVS. So you need to checkout latest
version from the CVS. One way is to use CVSget utility at the web site.
Another is to use WinCVS on Windows based machine (see
http://www.wincvs.org) or command line version of CVS (usually on UNIX
macines).

I recommend you checkout modules:

- binutils
- gcc
- or1k/or1ksim

Please let me know if you have problems with this procedure. Also in or1ksim
there is a small test microkernel with two tasks. When you compile it and
link it, you get a COFF binary that you load into or1ksim. or1ksim will
automatically recognize COFF format.

There is no loader for the real target yet.

regards,
Damjan
