Generate the Incremental OTA update package

Generate the Full OTA update package

Configure Poky and make a full build (build-\<>-image).
Fully flash the images as follows:
boot and recovery with \<>-boot.img
system with \<>-sysfs.ext4
recoveryfs with \<>-recovery.ext4
cache with \<>-cache.ext4
userfs with \<>-usrfs.ext4
Type the following command:
cd poky/build/tmp-glibc/deploy/images/\<>/\<>-ota-target-image-ext4
If there are any non-HLOS firmware updates, copy them to the radio/ directory.
Zip the directory for image generation as follows:
zip -qry /android_compat/build/tools/releasetools/target-files-ext4.zip *
Type the following command:
cd android_compat/build/tools/releasetools
Create a shell script for Full OTA named as full_ota.sh with the following content:
#!/bin/sh
if [ “$#” -ne 3 ]; then
echo “Usage : $0 target_files_zipfile target_name MMC_or_MTD”
echo “————————————————————-“
echo “example: $0 target_files_ubi.zip mdm9607 MTD”
echo “example: $0 target_files_ext4.zip apq8009 MMC”
exit 1

rm -rf target_files

mkdir -p target_files/SYSTEM
zipinfo -1 $1 | awk ‘BEGIN { FS=”SYSTEM/“ } /^SYSTEM\// {print “system/“ $2}’ | fs_config -D ../../../../poky/build/tmp-glibc/work/$2-\<>/\<>/1.0-r0/rootfs > target_files/META/filesystem_config.txt
cd target_files && zip -q ../$1 META/*filesystem_config.txt
SYSTEM/build.prop && cd ..
./ota_from_target_files -n -v -d $3 -p . -s “../../../device/qcom/common” –no_signing $1 update.zip

Generate the Incremental OTA update package

Using two separate workspaces, perform steps 1 through 6 mentioned in Section 2.1 to
prepare Version-1 (v1) and Version-2 (v2) target-files-ext4.zip files – considering v1 to be
the base workspace currently on the apq target which is to be upgraded to v2.
Create a shell script for Incremental OTA named as incremental_ota.sh with the following
content:
#!/bin/sh
if [ “$#” -ne 4 ]; then
echo “Usage : $0 v1_target_files_zipfile v2_target_files_zipfile
target_name MMC_or_MTD”
echo “————————————————————-“
echo “example: $0 v1_target_files_ubi.zip v2_target_files_ubi.zip mdm9607 MTD”
echo “example: $0 v1_target_files_ext4.zip v2_target_files_ext4.zip apq8009 MMC”
exit 1
