[yocto] Kernel Panics on armv4t with gcc.4.5.1

Thu Feb 3 09:00:23 PST 2011

Hi Diego,
 Good to know your kernel panic is gone. The 4.5.1 tree is arm specific linaro patches, which probably helping you. You can also try the meta-linaro layer.

http://git.pokylinux.org/cgit/cgit.cgi/meta-linaro/

And Darren is working on updating that layer currently. The gcc from that layer has linaro arm patches.

Thanks,
Nitin

Nitin,

After removing:

echo "/* GNU ld script
   Use the shared library, but some functions are only in
   the static library.  */
GROUP ( libgcc_s.so.1 libgcc.a )" > ${D}${libdir}/libgcc_s.so

from gcc-package-target.inc and gcc-package-cross.inc, the gcc 4.5.2 was successfully compiled.

And no kernel panic anymore. :-D

I just want to understand what is wrong with gcc 4.5.1.

Regards,

Diego,
  Can you try with 4.5.2 gcc from this branch: http://git.pokylinux.org/cgit/cgit.cgi/poky-contrib/log/?h=nitin/khem_gcc_nitin

Thanks,

Subject: [yocto] Kernel Panics on armv4t with gcc.4.5.1

Folks,

I'm not a kernel and neither a gcc expert developer, and after searching for a solution for the last 2 weeks I've decided to appeal to the list.

I'm trying to build a kernel image (2.6.32 and 2.6.30) for mini2440 (armv4t) with Yocto Project (poky master branch) and I'm facing a strange issue.

If I compile the kernel with Yocto gcc recipes (gcc 4.5.1) the kernel will panic on init (console printed message is attached for kernel 2.6.30 and 2.6.32).
But, if I compile the kernel with meta-oe gcc recipes (gcc 4.5) everything will be ok.
Just for your reference these is the gcc recipes which I'm using:
http://git.yoctoproject.org/cgit/cgit.cgi/poky/tree/meta/recipes-devtools/gcc
http://git.openembedded.org/cgit.cgi/meta-openembedded/tree/recipes-devtools/gcc

I've compiled with and without thumb instructions, but the issue remains.
I've tried to apply the patches gcc-armv4-pass-fix-v4bx-to-ld.patch and gcc-arm-volatile-bitfield-fix.patch, but no success.

Kind Regards,
