Toradex Colibri VF50 and VF61 Guide
To successfully set up the Boot to Qt software stack, you must closely follow the instructions in this section and perform all the described tasks.
In case of problems, see Troubleshooting.
Note: After you have installed the Boot to Qt software stack and want to connect to the target device with SSH or a serial cable, you can access the device by using the user
root and an empty password.
Before you install the Boot to Qt software stack, you should install the required software on the development host:
You can install the Boot to Qt software stack via the online installer. On Linux, see General Installation Issues for Linux.
Download the online installer and follow the instructions in the installation wizard. The Select components page in the wizard lists all the components that are available for your Qt account.
Select the Boot to Qt software stack for Toradex Colibri VF61 and Toradex Colibri VF50 with the following steps:
- Select Qt > Qt for Device Creation.
- Select the Boot to Qt software stack version.
- If you want to install Boot to Qt software stack for Toradex Colibri VF61 or VF50, select Toradex Colibri VF.
- Select Next.
To finish the installation, follow the instructions in the installation wizard.
The Boot to Qt software stack provides a system image (<target-device> Linux System) and a toolchain (<target-device> Linux Toolchain) for each target device. The system image contains the Boot to Qt software stack and needs to be flashed to the SD card or directly to the target device (see 3. Installing Boot to Qt on Target Device). building and developing applications for the target devices.
Note: Building the Boot to Qt system image and toolchain are not supported on Windows. Thus the sources of the Boot to Qt software stack are available only via the Linux online installer.
On Linux, remember to allow the execution of the installer binary. You can do this by using one of the following methods:
- On the command line enter the
chmod +x <filename>command.
- Right-click the file, and select Properties > Permissions > Allow executing file as program.
Note: Do not execute the installer as a root user or with sudo.
The installer will let you select a directory where the Boot to Qt software stack will be installed. In this documentation, the installation directory is referred to as
<INSTALL_DIR>. The default installation directories are:
Before you can test your Qt applications on the target device, you must flash the target device with an image containing the Boot to Qt software stack. After you have successfully flashed your device, Boot to Qt Demo Launcher automatically appears on the screen when you power on the device.
Use Flashing Wizard to flash the image to your device:
- Connect your SD card reader to the development host. Make sure that the SD card size is at least 2 GB.
- Launch Qt Creator.
- Select Tools > Flash Boot to Qt Device, and follow the instructions in Flashing Wizard.
In order to boot from the external SD card, U-Boot needs to be updated. See Booting from External SD Card.
In order to boot from an external SD card, U-Boot needs to be modified. Connect a serial cable to the device and enter into the U-Boot environment by pressing any key before the autoboot.
Enter following commands into U-Boot:
run setupdate run update
Reset or power cycle the device to continue.
To reset the U-Boot environment to new default values, enter the following commands in the U-Boot command line:
env default -a saveenv
New U-Boot commands are now stored into the device.
For more information about the boot process on Toradex Colibri iMX6, see Toradex Linux Booting.
It is possible to use the Toradex Capacitive Multi-Touch Adapter with Boot to Qt.
First follow the instuctions for setting up your screen here.
To enable touch support for your screen in Boot to Qt append the following lines to /etc/appcontroller.conf and uncomment line for the VF module being used.
#VF50 #env=QT_QPA_GENERIC_PLUGINS=evdevtouch:/dev/input/event1 #VF61 env=QT_QPA_GENERIC_PLUGINS=evdevtouch:/dev/input/event0
After you have prepared the target device, you must set up the development tools in Qt Creator for your device. That is, you must configure your target device to be used for each build and run kit.
Connect your device to the development host via USB and launch Qt Creator. In Qt Creator:
- Select Tools > Options > Build & Run > Kits.
- Select one of the predefined kits starting with Boot to Qt... that matches the type of your device.
- Select the correct device in the Device field.
- Select OK.
You are now ready to start developing with Qt for your device. For detailed information about how to deploy Qt projects to the device, see Tutorial: Deploying Your First Project with Boot to Qt.
After you have successfully flashed your device with Boot to Qt software stack, Boot to Qt Demo Launcher automatically appears on the screen when you power on the device. With Boot to Qt Demo Launcher, you can test the Boot to Qt demos that are included into Boot to Qt software stack images. For more information, see Qt Device Creation Demos.
