7.5 Getting Started with IAR™

IAR Embedded Workbench® for AVR® is a proprietary high-efficiency compiler not based on GCC. Programming and debugging of AVR128DA48 Curiosity Nano is supported in IAR™ Embedded Workbench for AVR using the Atmel-ICE interface. Some initial settings must be set up in the project to get the programming and debugging to work.

The following steps will explain how to get your project ready for programming and debugging:

  1. Make sure you have opened the project you want to configure. Open the OPTIONS dialog for the project.
  2. In the category General Options, select the Target tab. Select the device for the project, or if not listed, the core of the device, as shown in Figure 7-7.
  3. In the category Debugger, select the Setup tab. Select Atmel-ICE as the driver, as shown in Figure 7-8.
  4. In the category Debugger > Atmel-ICE, select the Atmel-ICE 1 tab. Select UPDI as the interface and, optionally, select the UPDI frequency, as shown in Figure 7-9.
Info: If the selection of Debug Port (mentioned in step 4) is grayed out, the interface is preselected, and the user can skip this configuration step.
