I am cc'ing the user's list because there are others
there who can share.
(1) RTEMS tools must be built for RTEMS. RTEMS has
a special configuration of the newlib C library and other
features enabled in the tools that will not be there
(2) AFAIK Altera has not done their part in the free software
process in relation to the NIOS2 tool chain. They have NOT
submitted their patches to the FSF projects for inclusion.
The RTEMS Project does not provide pre-built tools based
upon unsubmitted ports.
(3) You can build your own toolchain using the Altera
provided patches combined with RTEMS patches. I did
this long ago and it worked. If they have not updated
their tool versions in a long time, then you may have issues
with RTEMS using recent FSF releases while Altera is
using older tools.
If you care at all about free tools on the Altera NIOS2,
you need to make that known to Altera. The ball is
in their court to do the right thing. :)
