Step 2: Deploying

  • Deploying on an Android device simply happens by clicking on APP icon on the home screen.

  • You need to connect I-Pi SMARC IMX8M Plus with android image by MICRO USB OTG cable to your host computer.

  • To get the application working, two files must be deployed on the target device locally which means, the files must be placed in rootfs of the device.

    • Application/homa.cfg.sampleà /sdcard/homa.cfg
  • Application/Assets/AssetLibCff_Android_Target.bin à /sdcard/AssetLibCff.bin

This can be done by drag and drop utilizing Explorer or by the adb command line tool on power shell.

Installing App from Zip package

If you just got a ZIP package containing the APK (android application), asset file and config file, you don’t need any of the steps described before. You only need to install following files:

  • homa-arm64-v8a-debug.apk

  • homa.cfg

  • AssetLibCff.bin

You can do this by utilizing explorer by drag and drop, or much more convenient and faster by utilizing adb command on powershell.
