Building rel_imx_3.0.35_4.1.0 kernel fails to boot

[danmerillat]

I'm attempting to rebuild the image-as-shipped (L3.0.35_4.1.0_images/uImage) using the kernel config (from the config.gz inside the released image), but my build crashes during the boot process:

The exact git version is: bdde708ebfde (ENGR00275459 mx6sl: csi/v4l: fix kernel dump when do repeated streamon/streamoff), tagged as "rel_imx_3.0.35_4.1.0".

Compiler is the 2012.09 release as recommended in the freescale documentation.

Working official version:

Linux version 3.0.35-2666-gbdde708 (r65388@shlinux3) (gcc version 4.6.2 20110630 (prerelease) (Freescale MAD -- Linaro 2011.07 -- Built at 2011/08/10 09:20) ) #1 SMP PREEMPT Fri Aug 16 10:43:44 CST 2013

My build:

Linux version 3.0.35-03022-gbdde708 (dan@dan) (gcc version 4.7.2 (Sourcery CodeBench Lite 2012.09-63) ) #2 SMP PREEMPT Fri Sep 20 23:24:49 EDT

2013       

Note the git rev is identical, and the configuration I used is directly out of the working version.

Are there known issues with this compiler release?  If so, what's the correct compiler release for building the kernel from the freescale sources?

This is a bit late, but I just ran into this and found this patch fixed it:

ARM: 7668/1: fix memset-related crashes caused by recent GCC (4.7.2) opt... · 455bd4c · torvalds/lin...

Hi Dan,

I recommend you have a try the 2009.08 release compiler.

Best Regards

Dan

Unfortunately Codesourcery removes all traces of previous releases from their servers and their license specifically prohibits third party redistribution.   Is there any way to get the kernel to correctly build with either the current (2012-09) or mainline FSF release of GCC?

[danmerillat · Accepted solution]

I found a solution - the arm-gcc included in the android repo builds the kernel successfully.

make ARCH=arm CROSS_COMPILE=/opt/android/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi-
