After installation run the Phoenix Diagnostics App.

Click on "Update Controller Software button. Opening Screen1

The "Software Update" window will appear. Select the desired targets to update.

NOTE: On dual motor controllers updating the "Comm" on both motors is not necessary because it updates the same chip. Click "START" to begin the update.
