Hi, @Sanket_Parekh
I hope you are doing well.
We have compiled 'incremental_ota_update.zip' as per step 7.13 of document' Android_User's_Guide.pdf '.
We build incremental OTA follow the below-mentioned steps:
cd ${MY_ANDROID}
source build/envsetup.sh
lunch mek_8q_car-userdebug
./imx-make.sh bootloader kernel -j4
make target-files-package -j4
cp ./out/target/product/mek_8q/obj/PACKAGING/target_files_intermediates/mek_8q_car-target_files-eng.andrew.zip ./mek_8q_car-no-fec-sound.andrew.zip
----->Modify the source code to enable fec1 and sound
./imx-make.sh bootloader kernel -j4
make target-files-package -j4
cp ./out/target/product/mek_8q/obj/PAC KAGING/target_files_intermediates/mek_8q_car-target_files-eng.andrew.zip ./mek_8q_car-full.andrew.zip
./build/tools/releasetools/ota_from_target_files -i mek_8q_car-no-fec-sound.andrew.zip mek_8q_car-full.andrew.zip incremental_ota_update.zip
Compile to generate 'incremental_ota_update.zip'
But we can complete the compilation only if we solve two problems. The two questions are as follows:
① ImportError: No module named google.protobuf
Solution: pip install protobuf
② ExternalError: Failed to run signapk.jar: return code 1:
Error: Unable to access jarfile /home/workspace/imx-automotive-12.0.0_1.1.0/android_build/build/make/tools/framework/signapk.jar
Solution: cp out/soong/host/linux-x86/* build/make/tools/ -rf
OTA upgrade instructions are as follows:
update_engine_client --payload=file:///data/ota_package/payload.bin --update --headers="FILE_HASH=92f5jhI06QUmqyWCehXj6LG98kiBoJ7SIIdjzuRv3mQ=
FILE_SIZE=148325
METADATA_HASH=wFjPZRkq578QTUW+Tmejimu7+f/Ln67tn6HQZ7tVa0o=
METADATA_SIZE=146690"

I suspect there may be something wrong with the BSP environment.
Thanks & Regards,
