Did you build the microblaze compiler yourself (from
EDK101_GPL_GNU_src.tar.gz with the patch) or use the prebuilt binary
(from mb-gcc-4.1.1.gr2.i386.tar.gz)? As I said in a message to the
list a few days ago, when building the microblaze compiler, you need
to be careful what GCC compiler you use. I've never had an issue using
the prebuilt version for making firmware images, though.
