Editing Build android

To build Android, follow these three steps from the Android root. 

1.	export ARCH=arm

2.	export CROSS_COMPILE=~/projects/Android/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi-

3.	source build/envsetup.sh

4.	lunch pb200i-eng 

4a.     sudo apt-get install u-boot-tools uuid uuid-dev liblzo2-2 liblzo2-dev g++ gperf libswitch-perl libxml2-utils

4b.     cd bootable/bootloader/uboot-imx

4c.     export ARCH=arm

4d.
        export CROSS_COMPILE=~/projects/Android/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi-
        export CROSS_COMPILE=~/projects/Android5.1/Prebuilt_Lolli/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi-

4e.     make pb200i_android_config or make pb200iandroid_defconfig (5.1) or make hbi-120android_defconfig

4f.     make

4g.     cd ../../..

4h.     to build on 16.04
 sudo add-apt-repository ppa:openjdk-r/ppa  
 sudo apt-get update   
 sudo apt-get install openjdk-7-jdk  
 sudo apt-get install openjdk-7-jre

4i.     make bootimage

5.	make –j12

If this fails due to OpenJDK, try this: sudo update-alternatives --config java

Now make sdcard

6.      sudo ./device/fsl/common/tools/fsl-sdcard-partition.sh /dev/sdb

7.      ./tosd

Now if you want a ota distribution...

1.      make -j8 dist

1b.  New command &quot;make otapackage&quot;!!!  Try this if the previous command generates an image that boots only once.

2.      adb push out/dist/pb200i-ota....zip /sdcard

3.      adb shell

3a.         busybox cp /sdcard/pb200i-ota....zip /cache/update.zip

3b.         echo &quot;--update_package=/cache/update.zip&quot; &gt; /cache/recovery/command

3c.         reboot recovery

Now to build the new hbi kernel stuff...

sudo apt-get install lzop

  cd Uboot_Lolli/
  make hbi-120android_defconfig
  export ARCH=arm
  export CROSS_COMPILE=~/projects/Android5.1/Prebuilt_Lolli/gcc/linux-x86/arm/arm-eabi-4.8/bin/arm-eabi-
  make u-boot.imx
  cd Kernel_Lolli/
  make hbi-120_android_defconfig
  make zImage imx6q-hbi-120.dtb  -j 8
  sudo dd if=u-boot.imx of=/dev/sdX bs=1024 seek=1

Now to build the full Android/kernel distribution...

First replace ld in the prebuilts

  cd prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.11-4.6/x86_64-linux/bin/
  ln -s /usr/bin/ld.gold ld
  cd prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.11-4.8/x86_64-linux/bin/
  ln -s /usr/bin/ld.gold ld

sudo apt-get install bison uuid uuid-dev zliblg-dev liblz-dev curl m4 android-tools-fsutils

  export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64/
  export ARCH=arm
  export CROSS_COMPILE=~/projects/Android5.1/Prebuilt_Lolli/gcc/linux-x86/arm/arm-eabi-4.8/bin/arm-eabi- 
  make -j8 BUILD_TARGET_DEVICE=sd &gt; make.log 2&gt;&amp;1
    or
  make -j8 BUILD_TARGET_DEVICE=sd

To reset the workspace:

  git fetch --all
  git reset --hard origin/l5.1.1_2.1.0-ga-hbi-120
  cp arch/arm/boot/zImage /media/&lt;user&gt;/&lt;partname&gt;/ &amp;&amp; cp arch/arm/boot/dts/imx6q-hbi-120.dtb /media/&lt;user&gt;/&lt;partname&gt;/

To build on host 18.04 systems:

 export LC_ALL=C
