Android - OTA A/B update working log

A/B update 작업의 working log

step

u-boot(bootloader) 의 ab select, boot time의 dtb modify (vendor의 dev/block point runtime 변경)
device/nexell/con_svma : fstab, partmat, BoardConfig.mk, device.mk 추가/수정
bootctrl HAL 구현, IBootControl HIDL enable
TEST
incremental OTA packaging and TEST

step 4

update_engine_client 를 사용함에 있어서 new line, space 를 잘 맞춰주지 않으면 update_engine parser가 제대로 실행되지 않는다.

# update_engine_client --payload=file:///data/ota_package/payload.bin --update --follow \
--headers="\

FILE_HASH=UbCTf1cL7nvxEEhd3zI2S2w3jZOsgDjcLGmLN1x4Ssw=\

FILE_SIZE=279381404\

METADATA_HASH=Fnrg2Js8fFDXnnhwzKlanBYHDKQSZ14RcZ3g4yUiSxA=\

METADATA_SIZE=35956\

"

rebooting 후 update_verifier 를 실행해야 successful_boot flag가 true로 setting 되며, 이후 새로운 slot으로 안정적으로 booting이 된다.

# update_engine_verfier

step 5, doing

incremental OTA update는 pacakage를 생성하는 scheme을 분석해야한다. vendor 마다 boot.img 를 생성하는 방법이 다르기때문인듯하다. -i option으로 생성 후 update를 실행하면, boot partittion의 hash 가 miss match 되어 정상 동작하지 않는다. 일단 아래의 script를 trace 해본다.
