RE: [ECOS] MIPS 5KC Target

["Devaughn, Hans" <hans.devaughn@siemens.com>]

Nick,

I tried to duplicate your build for both the Atlas and Malta MIPS32 4KCs and
they failed with an error in platform.s. I had just discovered that building
on a NEW directory doesn't cause this error. Using NEW directories I have
successfully built the Atlas and Malta MIPS32 and the Malta MIPS64.
Obviously, as you indicated, there must be residue left on the old directory
that the configtool doesn't clean up.

Thanks
Hans

There doesn't seem to be anything wrong here.

So, let me get this right. Although
$(REPOSITORY)/$(PACKAGE)/include/var_cache.h
points to the correct file, somehow you are getting the mips32 version of
the file instead? That does not make any sense.

What does the $(PACKAGE) variable contain? It should be
"hal/mips/mips64/current".

Are you configuring in a fresh directory? Trying to move an existing
configuration from one target to another sometimes leaves remnants of the
old configuration around.

Try using ecosconfig. The following commands are what I used to test with:

$ mkdir atlas5kc.ram.kernel
$ cd atlas5kc.ram.kernel
$ ecosconfig new atlas_mips64_5kc kernel
$ ecosconfig tree
$ make
