At some point in AVR project development you need to deploy your application to a real AVR processor. This is supported by the AVR Eclipse Plugin with the help of the external programm avrdude. Avrdude stands for AVR Downloader / Uploader and is an open source utility to upload/download and manipulate the ROM and EEPROM contents of many AVR microcontrollers using the in-system programming technique (ISP).
Once a project is build it can be uploaded by right-clicking on the project and then selecting AVR -> Upload Project to Target Device. Alternatively an AVR project can be selected and then the upload can be started with the toolbar button.
The upload is started and its progress is shown in the console view.
