I got my OMAP target to build with GCC-4.6.0 using the latest
Poky tree after a fresh rebuild. Sadly, the Linux kernel
(2.6.37.3)
does not run correctly when built with this compiler. It
fails when enumerating the USB bus :-(
Are there known issues with the Linux kernel on ARM and GCC-4.6?
There has been fixes on top of 4.6.0 the one we have right now is
vanilla
4.6.0 release. I plan to add second set of patches but you have to
dig a bit
more to identify the problem
I have some updates for gcc 4.6.0
they are staged in
http://git.openembedded.org/cgit.cgi/openembedded-core-
contrib/log/?h=kraj/gcc-4.6
(top 3 patches)
Please test them out and if you are lucky
your problem might be fixed too.
All, please try these patches and provide any feedback
I was able to build my kernel (ARM OMAP/3530 based) using this, but
the USB still doesn't work, so no improvement, sorry.
Gary,
Is the USB breakage is due to gcc 4.6.0 ?
Yes, that's the only change. Building the kernel from the same
source repository with 4.5.2 (using patches from you and Khem Raj)
works perfectly.
