Hi,
I've been doing okay so far with the 3.14.28/yocto 1.8 release. I'm now looking at adding support for the wifi chip on my board which uses wl12xx. On 3.0.35/ltib, I was able to just manually apply the backported patches to the kernel and get things to work.
With yocto and 3.14.28, this looks a bit different. Firstly, I need to use the kernel backports tool ( WL18xx System Build Scripts - Texas Instruments Wiki ) which is not part of yocto. I'm at the step that needs the setup-env. With previous versions of yocto for imx, I was able to get this from the log.do_compile logs that are generated in the build directory. But I noticed that with this version, the log is much shorter. Eg:
less ~/yocto_3.14.28-1.0.1/build/tmp/work/imx6slevk-poky-linux-gnueabi/linux-imx/3.14.28-r0/temp/log.do_compile.888
DEBUG: Executing shell function do_compile
NOTE: make -j 1 zImage CC=arm-poky-linux-gnueabi-gcc -mno-thumb-interwork -marm LD=arm-poky-linux-gnueabi-ld.bfd LOADADDR=0x80008000
scripts/kconfig/conf --silentoldconfig Kconfig
I think I can set this up manually figuring out each parameter. For example, on my setup this becomes:
export TOOLCHAIN_PATH=/home/test/yocto_3.14.28-1.0.1/build/tmp/sysroots/x86_64-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-gcc
export KERNEL_PATH=/home/test/yocto_3.14.28-1.0.1/build/tmp/work/imx6slevk-poky-linux-gnueabi/linux-imx/3.14.28-r0/git
But this seems error prone and messy. I was wondering if I missed an easy step that could have been done to generate the setup-env needed for kernel backports tool, or if there is an easier way to add wl12xx support.
Thanks!
