Running on the Device

Before you install the application and run it on the development board, install the DevEco Device Tool by following operations provided in HUAWEI DevEco Device Tool User Guide. Burn OpenHarmony into the development board, and run it on the board. For details about how to compile, burn, and run an image, see the Quick Start Overview. After the image is running normally and the system is started properly, perform the following steps to install or uninstall the application:

1. Store the compiled unsigned application installation package and installation tool in an SD card and insert the SD card into the development board slot. The installation tool is in dev_tools of the directory where the image file is generated.

2. Run the following command to disable signature verification, which is enabled by default for application installation:

   ./sdcard/dev_tools/bin/bm set -s disable
   

3. Run the following command to install the application:

   ./sdcard/dev_tools/bin/bm install -p /sdcard/airquality.hap 
   

   The dev_tools directory stores the installation tool, and airquality.hap is the application installation package. Replace it with actual the package name.

4. After the application is installed, touch the application icon on the home screen to enter the application.
