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.

And no kernel panic anymore. :-D I just want to understand what is wrong with gcc 4.5.1.

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, -- *dS Diego Sueiro /*long live rock 'n roll*/
