@goldenfenix This is because you are building with a standard gcc.
You may try the patches I've put in http://moinejf.free.fr/opi2/, but some modules would not compile with loboris's .config (I don't remember which).
Otherwise, you may start with my config.

Have you tried to set up a working standalone cross-compiler toolchain (eg. from Linaro) to avoid problems?

Get http://releases.linaro.org/14.11 ... ux-gnueabihf.tar.xz and unpack it below /usr/local.

Then prior to starting the script do a

export PATH="/usr/local/gcc-linaro-4.9-2014.11-x86_64_arm-linux-gnueabihf/bin/:$PATH"

Copy code

and then as usual. Report back please.

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
1536000

And what about /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq ?

Done how in the instruction, but the same error.

unrecognized command line option ‘--min_array_alignment=4’
unrecognized command line option ‘--no_unaligned_access’

@goldenfenix
You need to patch source before you compile!

http://jungels.net/articles/diff-patch-ten-minutes.html

Without patch you can only compile this kernel source with included SDK binary toolchain (4.6) or for example (maybe simpler) with ubuntu 12.04and installing toolchain (4.6.4) with apt-get install.

scaling_cur_freq changes constantly...
try to run some cpu intensive program and at the same check scaling_cur_freq, it will go to scaling_max_freq.
Or install CPU frequency applet...
480000 (480MHz) is the minimal CPU freq.

Why do this ?
For different tasks will be different loading cores.
