This article assumes that you've already created a project for the ATtiny817 Xplained Pro. If you haven't yet done so, please go through the steps in theCreating a Project in Atmel Studio 7 page.

1

Open the Tool tab

Click theTool button located in the top menu bar to open the Tool tab.

2

Select tool/debugger from the drop down list.

The Tool tab of theProject Properties window will open. In the drop-down menu, select the 'EDBG' tool.

• The serial number of the tool will accompany its name in the drop-down menu. This serial number is printed on the back side of each tool, allowing differentiation when more than one is connected.
• These steps can always be repeated if a different tool should be used for the next debug/ program session.

On the ATtiny817 Xplained Pro, the EDBG is permanently connected to the target MCU, but for a custom hardware solution is it necessary to ensure the target device is powered and properly connected before a debug session can be launched.

To learn more about the other settings in the Tool tab, please visit theTool options section in the Studio User Guide.

Settings Verification

You can verify the tool and project configuration setup by compiling the empty project and writing it to the ATtiny817.

Click on 'Start Without Debugging' located in theDebug menu. This will compile the project and write it to the specified target MCU using the configured tool.

If there is new firmware available for the selected tool, theFirmware Upgrade dialog will appear. Click theUpgrade button to start the firmware upgrade.

Depending on the state of the connected tool and the actual firmware upgrade, the upgrade may fail on the first attempt. This is normal and can be resolved by disconnecting and reconnecting the kit before clickingUpgrade again. After the upgrade has completed, the dialog should say "EDBG Firmware Successfully Upgraded". Close the dialog box and make a new attempt at programming the kit by clicking on 'Start Without Debugging' again.
