How to perform OTA upgrade on the OKT507-C development board on the Android system [Copy link]

OTA upgrade is the standard software upgrade method provided by the Android system. It is very powerful and provides two modes: full upgrade (complete package) and incremental upgrade (difference package). Below we take the OKT507-C development board as an example to explain the specific steps.

01

OTA upgrade package compilation

Compile the firmware

Configure the compilation environment

Enter the source directory and execute the following command:

$ cd OKT507-android-source/longan

$./build.sh config

Enter 0 in the terminal and select Android.

$ cd /work/OKT507-android-source/android

$ source build/envsetup.sh

$ lunch okt507_c-userdebug

Compile all

cd /work/OKT507-android-source/longan

$ ./build.sh

$ cd /work/OKT507-android-source/android

$ extract-bsp

$ make installclean

$ make –j4

The compiled image is located in the out/target/product/okt507-c directory.

Packaging images

$ pack

The image file after packaging is longan/out/t507_android10_okt507_uart0.img

Compile OTA complete package and differential package

$ pack4dist

The corresponding version of the OTA package can be generated.

Target file package:

out/target/product/okt507-c/obj/PACKAGING/target_files_intermediates/okt507_c-target_files-eng.xxz.zip

Full upgrade package:

out/target/product/okt507-c/okt507_c-full_ota-eng.xxz.zip

The target file package is the basic material for making incremental upgrade packages. The target file package needs to be saved together with the firmware for subsequent generation of OTA packages.

The command to generate a complete package separately:

$./build/tools/releasetools/ota_from_target_files target.zip ota.zip

The command to generate a differential package separately:

$./build/tools/releasetools/ota_from_target_files -i origin.zip target.zipinc.zip

Note: Among them, origin.zip is the target file package of the basic version (i.e. the version to be upgraded), target.zip is the target file package of the current version, and inc.zip is the differential package.

Upgrade using OTA package

Use the complete package for a full upgrade and the differential package for an incremental upgrade. Rename the upgrade package to be used to update.zip.

Use TF card or USB flash drive to upgrade

Click Android Settings->System->Advanced->Local Upgrade, as follows:

Click OTA system upgrade, and the scanned update.zip package will be displayed.

Click update.zip, and the interface will prompt that it is verifying whether it can be installed. After verification, the Start Installation button is activated, and click to start the installation.

The interface will display verification, process the installation package, and then restart. After the restart, the interface enters recovery. After the upgrade, it will automatically restart and the OTA upgrade is completed.

Upgrading using Adb

Put the upgrade package update.zip into the PC, such as the root directory of drive F.

Run the following command in cmd on the PC side, and the development board will automatically restart and enter recovery.

adb reboot recovery

On the development board, use the volume up and down keys to select Apply update from ADB

Enter in cmd on the PC:

adb sideload F:\update.zip

Start the upgrade.

After the upgrade, the development board interface prompts:

Install from ADB completed with status 0

Select Reboot system now. After the development board restarts, the OTA upgrade is completed.
