### prepare

1. prepare ubuntu 16.04 for build project
2. sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential chrpath socat xterm g++ libstdc++6 lib32stdc++6 \
libpulse-dev libevent-dev ninja-build rpm2cpio libsdl1.2-dev zip
3. sudo ln -s /bin/bash /usr/bin/sh
4. cp tool/gn /bin ; chmod 777 /bin/gn
5. Download the donwloads directory instead of slow downloads at compile time


### build

1. cd mt8516_avs_share
2. export TEMPLATECONF=${PWD}/meta/base/conf/mt8516/aud8516p1v2-consys-slc-128
3. source meta/poky/oe-init-build-env
4. bitbake mtk-image-aud-8516

other build cmd:

bitbake -c cleanall lk && bitbake lk -f

bitbake -c cleanall linux-mtk-extension && bitbake linux-mtk-extension -f

### compile linux kernel
bitbake linux-mtk-extension -c cleanall

### update

use adb to update image

1. cd build/tmp/deploy/images/aud8516p1v2-consys-slc-128

2. adb push update.zip /tmp/ && adb shell /bin/upgrade_app /tmp/update.zip

### burn

use usb burn all image

1. cd build/tmp/deploy/images/aud8516p1v2-consys-slc-128

2. sudo python flashimage.py -t(erase sn)
   sudo python flashimage.py(dont erase sn)
3. press v- key  and plugin usb

###OTA
1. change version:
arch/arm64/boot/dts/mediatek/aud8516p1v2_consys_slc_128_yocto.dts
ver= "101001";  //this mean version is 1.0.1.001;
next version:
ver= "101002";//this mean version is 1.0.1.002;
2. output ota file:
comand:
tool/build_otazip.sh 1.0.1.002 build/tmp/deploy/images/aud8516p1v2-consys-slc-128/update.zip
then output ota file is:Firmware__OTA_1.0.1.002_.zip
