Hello, guys!
Not sure if it's right place for my question. If it isn't, please give
me the right direction.
I'm currently working on AVR32-based project and want to use OE as my
build environment. Actually, there is some support for AVR32 already
in tree, but I found it pretty unusable: it can't even build usable
toolchain. I'm working on my private branch and managed to get basic
things working. Is where any chance for me to see that changes pushed
upstream?
With best regards,
Ilya Yanok.

But am also stuck at getting correct gcc stuff up via oe. Maybe we can lign up togethere and share. I currently had the most success out of the atmel provided gcc toolchain.

Unfortunately, init crashed with segfault... Don't know... needs further investigation. If you interested in my work, let's discuss how we can share it.

I'm there but not always. My nick is yanok. > Would you like to send me local.conf ? and did you do any chances to oe 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. > to build cleanly ? Actually a lot of. > The segfault will be easy to debug. Did you use the basic minimal image ?

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).
