Hi Guys, I feel like playing with the Hammerhead Kernel
I have figured out how to build the project: https://code-review.phablet.ubuntu.com/p/aosp/platform/manifest.git -b phablet-4.4.2_r1 then flash my hammerhead using rootstock-touch-install and a daily image. So far so good. Next, what do I have to do with the kernel sources project https://code-review.phablet.ubuntu.com/ubuntu/kernel/trusty -b hammerhead ? I have tried 3 ways: 1) building kernel in tree - copy the kernel sources to kernel/lge/hammerhead - modify device/lge/hammerhead/BoardConfig.mk in order to make TARGET_KERNEL_UBUNTU := false and add TARGET_KERNEL_CONFIG := hammerhead_defconfig TARGET_KERNEL_SOURCE := kernel/lge/hammerhead --> built kernel image smaller than the prebuilt one from rsalveti PPA (I guess it is a dtb story). Nothing will work 2) building kernel in tree with cyanogenmod BoardConfig.mk --> built kernel image sizing the same as the prebuilt one from rsalveti PPA (a dtb one by the way). Recovery works, Ubuntu-Touch won't boot though 3) building myself the kernel sources export ARCH=arm export SUBARCH=arm export CROSS_COMPILE=arm-eabi- make hammerhead_defconfig make ... no result yet, it was still building when I dicided to write this email as I don't know what to do next. What is the proper way to build the kernel and to produce the img boot recovery and system files? Can you give me some guidelines? I am keeping notes of that process and will suggest a wiki update. Regards David
