= Simulating 825gen2 App Operation =

The development environment allows 825 app operation to be simulated. This saves time developing applications and allows for debugging. However, not all aspects of application operation can be simulated.

For 825 simulation when logging into the development environment be sure the desktop graphics type is:
 "Desktop Session: Plasma (Wayland)"

Click the "Toolbar" item "825 simulator for debugging an app"

Click "Tools", "Settings…" to configure the simulator.

Option card "Details" may be configured.

Simulation in the development environment is achieved by having a build configuration for each app such as "Debug-ARM825-SIM" that compiles the app with the default GCC compiler in the VM to build the app to run on Intel x86 processor. The lib825ev, and other libraries have corresponding "Debug-ARM825-SIM" build configurations. The build configuration must be setup to link to the appropriate library files.

In case the VM is logged in as Plasma (X11) when starting a simulated app the console message will show:

The running simulator may appear similar to:
