Hi Robert,

Yes. I'm there but not always. My nick is yanok.

local.conf is pretty simple:
MACHINE = "at32stk1000"
DISTRO = "oavr32-uclibc"
BUILD_ARCH = "i686"
PREFERRED_VERSION_linux = "2.6.23"
DEBUG_OPTIMIZATION = "-O0 -g"

Ok, I defined my own distro oavr32-uclibc (actually a pair
oavr32/oavr32-uclibc but former is unusable as there is no glibc on
avr32 AFAIK) based on generic/generic-uclibc distros. Changes are
mainly toolchain components preferred versions. I've attached these
files.

PREFERRED_VERSION_linux = "2.6.23" is just hack to get some kernel
compile as for now I prefer to compile the kernel outside oe. In the
right case we should provide new kernel recipe (something like
linux-avr32) and choose it via PREFERRED_PROVIDER_virtual/kernel =
"linux-avr32" from machine configuration.

Actually a lot of.

Yes, the one created by bitbake minimal-image

As I said before I compile the kernel by hand but ...

I believe kernel don't use libc at all. It may be incompatibility in
compilers ABIs but I tried to recompile the kernel with compiler built
by oe and get the same result (I don't get many segfaults really,
there is only one and then system hangs).

With best regards,
                           Ilya.
