[Buildroot] kernel cross compilation problem (at91sam9260)

Hi,
 
I had the same problem going from 800k to 3MB kernels. It was not related to compilers. 
 
The size is due to a large initrd filesystem.
 
Clean everything out, the standard cleans don't seem to do it. 
 
I can't say what exactly gets it done, removing init ram filesystem, but it looks like toolchain rebuild as well is required.
 
, and in .config
 
# BR2_TARGET_ROOTFS_INITRAMFS is not set
 
Best Regards,
Rick

Hi,

Dropping back to using gcc 3.4.6  and uclib x.x.28 worked for me.  - not a proper fix, but it was a combination that worked andI was fed up of trying combinations :)


Regards
Wayne

	hello,
	I'm using the buildroot-20080206.tar.bz2 package to build a rootfilesystem and a cross compilation toolchain for my embedded board (sam9260).
	I tried to cross compile (arm-linux-gcc-4.1.2) a 2.6.23 linux kernel seperately (not the one included in buildroot) , and i noticed that the size had increased by 3Mb respect to my old version.
	On the other hand when i try to use the generated kernel, it hangs at the stage

	Does anyone encounters this kind of problem ?
