Starting programs in a basic solution image

If a program that you want to start uses file systems (via the VFS component), the following is required before starting the program:

1. Use the menu to open the extension settings window: File → Preferences → Settings, then select Extensions → KasperskyOS.
2. Set the client:kl.VfsSdCardFs value for the VFS_FILESYSTEM_BACKEND environment variable in the Application Environment Variables parameter.

To start a program in a basic solution image:

3. Make sure that the basic solution image is started according to the instructions provided in the Starting a basic KasperskyOS-based solution image section.
4. Click the button for selecting the device or QEMU emulator in the lower panel.
5. Select the previously started basic solution image.
6. Build the program according to the instructions provided in the Building a program in Visual Studio Code section.
7. Make sure that the program has been packed into a KPA package.

   You must use the CMake commands of the kpa library to pack a program into a KPA package.

8. Click the target selection button . In the drop-down list, select the built program KPA package that is signed as [application] in the list.
