Hello John,
I would like to use fnord too.
I downloaded petalinux-v0.20-rc3.tar.gz from the petalogix site.
When I run "make user_only" I get next error:
/home/petalinux-v0.20-rc3/tools/linux-i386/microblaze-uclinux-tools/bin/
../lib/gcc/microblaze-uclinux/3.4.1/../../../../microblaze-uclinux/bin/l
