Getting Started with IAR

IAR Embedded Workbench
GCC. Programming and debugging of ATmega4809 Curiosity Nano is supported in IAR
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.
