32 bit build on DB845C

I am trying to build 32bit Android build on DB845C. I have made below changes to generate 32build
TARGET_ARCH := arm
TARGET_ARCH_VARIANT := armv8-2a
TARGET_CPU_VARIANT := kryo385
TARGET_CPU_ABI := armeabi-v7a
TARGET_CPU_ABI2 := armeabi
I have commented out the other variables related to TARGET_2ND_ARCH.
Build was successful and device booting but java system services are not getting started.
