Building and flashing a Dynamic Download Project▲

This tutorial will guide you through building an INTEGRITY project for a Qt example application on a Windows 10 host. You can select any Qt example application that uses the Supported Qt modules.

Preparing the Qt application build environment▲

Before building the INTEGRITY project, you need to prepare your build environment. Run the setEnvironment.bat script from the Windows CMD terminal. For more information about the script, see Creating a batch script for Windows 10.

Sélectionnez

setEnvironment.bat

Building the Qt application example▲

To build Qt 6 application using CMake, run the following commands in the Windows CMD terminal:

Sélectionnez

"Qt installation path&gt;\bin\qt-cmake.bat" CMakeLists.txt -GNinja
-DCMAKE_PREFIX_PATH="C:\Users\user\targetbuild"
-DQt6_DIR="C:\Users\user\targetbuild\lib\cmake\Qt6"
-DQt6Core_DIR="C:\Users\user\targetbuild\lib\cmake\Qt6Core"
-DQt6Gui_DIR="C:\Users\user\targetbuild\lib\cmake\Qt6Gui"

 cmake --build .

Where, qt-cmake is the wrapper script that calls CMake to configure your project with appropriate include paths.

Creating a Dynamic Download Project in MULTI▲

Start MULTI Launcher and select File > Create workspace.
In the creation window mode select New Project and click OK.
In the dialog Project Wizard, select a path where the new project is to be created e.g. C:\Users\user\Documents\My Projects\Project1\default.gpj and click Next.
Select INTEGRITY in Operating System dialog and click Next.
Select Finish.
Select Create New > Dynamic Download > Next.
Select Settings For Dynamic Download > Finish.

Building a Dynamic Download Project▲

Edit and save myproject.int file in the project tree:

Sélectionnez

AddressSpace
  Name qtapp
  Filename C:\path\to\your\qt\app\binary
  MemoryPoolSize 0x2700000
  Language C++
  HeapSize 0x90000
  Task Initial
    StackSize 0x90000
    StartIt false
  EndTask
  Extendedmemorypoolsize 0x300000
EndAddressSpace

Create a new file called 'multi_commands' and add the following commands to it:

Sélectionnez

switch -component "debugger.task.qtapp.Initial"
route "debugger.task.qtapp.Initial" { __ntwcommand prepare_target }
wait -load
switch -component "debugger.task.qtapp.Initial"
route "debugger.task.qtapp.Initial" { __ntwcommand resume }
wait -time 240000 -stop
switch -component "debugger.task.qtapp.Initial"
unload myproject
wait -time 8000 -stop
savedebugpane cmd "autotestresult.txt"
quitall

Run building and loading commands from the Windows CMD terminal:

Sélectionnez

multi.exe "C:\Users\user\Documents\My Projects\Project1\default.gpj" -build myproject &amp;
multi.exe "C:\Users\user\Documents\My Projects\Project1\dbg\bin\myproject" -connect="rtserv2 192.168.1.1" -p C:\Users\user\multi_commands &amp;

"rtserv2 192.168.1.1" is a board IP address. Check Set up the wiring to set up the board network.

It takes several minutes to deploy by Dynamic Download.
