4-5 Building Executables for RZ/G2L

Now, we will try to deploy a version of our application to the Renesas RZ/G2L target board after testing on a PC.

Step 1: Set Up Kits In Qt Creator​

Open Qt Creator and click on Projects in the left menu.

Add the RZ/G2L kit by selecting Add Kits > RZ/G2L.

Step 2: Build and Transfer the Executable​

Click the Build button located at the lower-left corner.

The compiled executable will be located in:

build-ex01-RZG2L-Debug/ex01

Use the scp command to send the file to RZ/G2L board:

scp ex01 root@rz-ip-address:/home/root
tip

The Linux image built with the core-image-qt parameter includes SSH and SCP functionality. If SSH fails due to newer PC client restrictions on the ssh-rsa algorithm, resolve the issue by adding the following parameter to your SSH command:

ssh -v -oHostKeyAlgorithms=+ssh-rsa root@<RZ/G2L_IP>

Alternatively, edit the SSH configuration file:

vim ~/.ssh/config

And add the following:

Host *
  ServerAliveInterval 10
  HostKeyAlgorithms +ssh-rsa
  PubkeyAcceptedKeyTypes +ssh-rsa

Step 3: Run the Executable​

Run the executable using the command below:

./ex01

Step 4: Coffee Machine Example​

The official Qt Coffee Machine Example (Qt 5.15 LTS) is available here, but it cannot be compiled in the current environment.

Please use a modified version that is compatible with Qt 5.6.3 and is tested on RZ/G2L:

git clone https://github.com/yourskc/moil_coffee.git

Follow the steps from above to compile the Coffee Machine project in Ubuntu 22.04.

Transfer and execute the compiled project on RZ/G2L using the same process.

The project can be controlled via a mouse or a touchscreen, making it functional for mobile or smart device interfaces.

tip
  • Practice QML and Qt Quick programming using this example.
  • Study the asset usage in the project for inspiration and guidance in creating your own UI designs.
