Building applications with prebuilt Qt Quick Ultralite libraries

Open the CMake project file for the example you want to build and configure it with the kit you created earlier. Once the project is configured, select Run or press Ctrl+r on your keyboard to build and flash the binary to the target.

Reading debug messages

By default, log data is redirected to JLink CDC UART Port (USB COM port).

Port settings

Setting	Value
Bits per second	`115200`
Data bits	`8`
Parity	`None`
Stop bits	`1`
Flow control	`None`

Debugging

Renesas e² studio

Renesas e² studio lets you debug a project using a custom configuration.

Create a Bare Metal - Minimal project for EK-RA8D1.
Build the project.
Copy the Qt Quick Ultralite .elf file into the Debug folder of the e² studio project.
Take a copy of the original .sbd file and rename it with same name as the Qt Quick Ultralite .elf file.
Select Run from the top menu.
Select Debug Configurations....
Select Renesas GDB Hardware Debugging.
Set the Qt Quick Ultralite .elf to the C/C++ Application:.
Select Apply and Close.
Select Launch in 'Debug' mode.
