please try first to run the provided examples (e.g. HelloWorld) for your target according the Getting Started with STM32F746 Discovey documentation.

Does this work?

In a second step, you can try to run the example DeviceIntegration which demonstrates the access to the LED.

Does this work?

Now, you can make your own modifications and implement your own GUI. If there is still an error message, please check if there are other (earlier) messages within the Log Window. You can post the entire message here.

Best regards,


Can you please tell the OutputDirectory configuration

The attribute OutputDirectory should refer to the \Application\GeneratedCode directory within your Build Environment. By using the provided template, it will be very easy to build the UI project for your target.
