Hi, I’m trying to compile a kernel module for beaglebone black.
I’m working on ubuntu 14.04
uname -a
Linux joompiol-GX708AA-ABM-a6330la 3.13.0-24-generic #46-Ubuntu SMP Thu Apr 10 19:11:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
I followed instructions provided here: http://beagleboard.org/linux
I installed toolchain without problems…
~$ wget http://www.angstrom-distribution.org/toolchains/angstrom-2011.03-x86_64-linux-armv7a-linux-gnueabi-toolchain-qte-4.6.3.tar.bz2
~$ sudo tar -C / -xjf angstrom-2011.03-x86_64-linux-armv7a-linux-gnueabi-toolchain-qte-4.6.3.tar.bz2
~$ export PATH=/usr/local/angstrom/arm/bin:$PATH
**This lines works fine:**
~$ git clone git://github.com/beagleboard/kernel.git && cd kernel
~/kernel$ git checkout 3.8
~/kernel$ ./patch.sh
~/kernel$ cp configs/beaglebone kernel/arch/arm/configs/beaglebone_defconfig
~/kernel$ wget http://arago-project.org/git/projects/?p=am33x-cm3.git\;a=blob_plain\;f=bin/am335x-pm-firmware.bin\;hb=HEAD -O kernel/firmware/am335x-pm-firmware.bin
~/kernel$ cd kernel
~/kernel/kernel$ mkdir rootfs
~/kernel/kernel$ make ARCH=arm CROSS_COMPILE=arm-angstrom-linux-gnueabi- beaglebone_defconfig
**The next line gave me this:**
/kernel/kernel# make ARCH=arm CROSS_COMPILE=arm-angstrom-linux-gnueabi- -j4 uImage dtbs
CHK include/generated/uapi/linux/version.h
CC scripts/mod/empty.o
/usr/bin/as: unrecognized option ‘-EL’
make[2]: *** [scripts/mod/empty.o] Error 1
make[1]: *** [scripts/mod] Error 2

When I try to compile a simple hello kernel module give me this:
/home/joompiol/hello# ARCH=arm CROSS_COMPILE=arm-angstrom-linux-gnueabi- KDIR=/kernel/kernel make
make -C /kernel/kernel SUBDIRS=/home/joompiol/hello modules
