Android OTA Update
Patch Information
Ensure the following modifications are in build.sh:
diff --git a/build.sh b/build.sh
index 95b62fe30b..13d54e0763 100755
--- a/build.sh
+++ b/build.sh
echo "Start pack image"
cd android
pack
+ rm out/target/product/ceres-c3/ceres_c3-full_ota*.zip
+ pack4dist
+ mv out/target/product/ceres-c3/ceres_c3-full_ota-eng.*.zip out/target/product/ceres-c3/ceres_c3-full_ota-eng_$(date +%Y%m%d)_$(date +%H%M).zip
cd -
}
Note
1. The OTA package is generated after executing pack4dist.
2. Final path of the full OTA package after compilation: android/out/target/product/ceres-c3/ceres_c3-full_ota-eng_*.zip
Prerequisites
1. When powered by battery, ensure sufficient battery level during the update; when operating without a battery, the DTS must disable battery power supply.
battery_power_supply: battery-power-supply {
compatible = "x-powers,axp803-battery-power-supply";
- status = "okay";
+ status = "disabled";
pmu_chg_ic_temp = <0>;
pmu_battery_rdc= <93>;
Warning
1. This option is enabled by default in the software to be compatible with both boot scenarios (with and without battery).
2. When operating without a battery, this option must be disabled to support OTA updates. Otherwise, the OTA update will detect a low battery level and cause the update to fail.
2. Ensure the build date of the OTA package image is newer than the build date of the existing image on the mainboard.
Tip
Ensure make installclean is enabled during compilation so that the prop information is updated correctly.
