Kernels for Amazfit watches

Development of working kernel sources for Amazfit watches

This project aims at developing working open source kernels for all the Amazfit smart-watches. Such kernel sources will help the community develop/port other popular Softwares for the Amazfit devices.

In the main branch (here) are the Ingenic's Newton 2 Plus kernel-3.10.14 sources. Newton 2 Plus is a development board which have many similarities with the Amazfit smart-watches, thus we will base our kernels on these sources. The sources were pull from ingenic's git server for use with Amazfit ingenic products.

Building the Sources with Ingenic's Android

Some info on building the sources of the ingenic newton 2 plus. This is not exactly a tutorial... This was tested on Ubuntu 18.04, but it may work on other GNU/Linux too.

Install dependancies

First get adb and fast boot

sudo apt-get install android-tools-adb android-tools-fastboot

And some more dependancies that I think you may need

sudo apt-get install git-core gnupg flex bc bison gperf build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev libgl1-mesa-dev libxml2 libxml2-utils xsltproc unzip imagemagick lib32readline-dev lib32z1-dev liblz4-tool libncurses5-dev libsdl1.2-dev libssl-dev libwxgtk3.0-dev lzop pngcrush rsync schedtool squashfs-tools xsltproc yasm

Install Java 7 (needed by this android version)

So... you need jdk7... and you will have to manualy install it

Thus, you may added the openjdk repo for to install the version 8 and some other needed depenancies

sudo add-apt-repository ppa:openjdk-r/ppa  
sudo apt update
sudo apt install openjdk-8-jdk
# Then I got the packages from the experimental repo
# https://packages.debian.org/sid/libjpeg62-turbo
# https://packages.debian.org/experimental/openjdk-7-jre-headless
# https://packages.debian.org/experimental/openjdk-7-jre
# https://packages.debian.org/experimental/openjdk-7-jdk
# and installed them
sudo dpkg -i libjpeg62-turbo_*_amd64.deb
sudo dpkg -i openjdk-7-jre-headless_*_amd64.deb
sudo dpkg -i openjdk-7-jre_*_amd64.deb
sudo dpkg -i openjdk-7-jdk_*_amd64.deb
sudo apt --fix-broken install
# Then change the selected java version
sudo update-alternatives --config java
sudo update-alternatives --config javac
sudo update-alternatives --config javaws # no option, ignore
sudo update-alternatives --config javadoc

Get repo from ingenic

This will take some time...

wget http://git.ingenic.com.cn:8082/bj/repo
chmod +x repo
./repo init -u http://git.ingenic.com.cn:8082/gerrit/mipsia/platform/manifest.git -b ingenic-android-lollipop_mr1-kernel3.10.14-newton2_plus-v3.0-20160908
./repo sync

Personally, I failed to compile v3.0 (it had some API errors)

#./repo forall -c "git reset --hard ingenic-android-lollipop_mr1-kernel3.10.14-newton2_plus-v3.0-20160908"

So it got the v2.0

# Get v2.0
./repo forall -c "git reset --hard ingenic-android-lollipop_mr1-kernel3.10.14-newton2_plus-v2.0-20160516"

Fix some errors

Now edit build/core/clang/HOST_x86_common.mk to fix clang bug. Add the -B$($(clang_2nd_arch_prefix)HOST_TOOLCHAIN_FOR_CLANG)/x86_64-linux/bin \ on line 11, so the lines from 8 to 12 would be:

ifeq ($(HOST_OS),linux)
CLANG_CONFIG_x86_LINUX_HOST_EXTRA_ASFLAGS := \
  --gcc-toolchain=$($(clang_2nd_arch_prefix)HOST_TOOLCHAIN_FOR_CLANG) \
  --sysroot=$($(clang_2nd_arch_prefix)HOST_TOOLCHAIN_FOR_CLANG)/sysroot \
  -B$($(clang_2nd_arch_prefix)HOST_TOOLCHAIN_FOR_CLANG)/x86_64-linux/bin \
  -no-integrated-as
