[Buildroot] kernel cross compilation problem (at91sam9260)

[Buildroot] kernel cross compilation problem (at91sam9260)

[grego rigolo]

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 
uncompressing Linux ....................
Does anyone encounters this kind of problem ?
greg

[Buildroot] kernel cross compilation problem (at91sam9260)

[Wayne Keenan]

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

[Buildroot] kernel cross compilation problem (at91sam9260)

[Rick Foos]

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

[Buildroot] kernel cross compilation problem (at91sam9260)

[Doug the RockRat]

Is it possible that a boot logo was perhaps added?  
That does add a significant amount of size to the
kernel.
