Turbine Compact - Image recovery

This article describes how the flash image of a Turbine Compact station can be recovered.

Before starting the upgrade process it is important to identify if the bootloader is corrupted or not.

• Corrupted bootloader
• The bootloader is intact

Requirements

• The application "Turbine Station Production Upgrade Application" installed on a Windows PC.
• A serial connection from the PC to the Turbine Compact board, using a USB to Serial cable
• A terminal emulator program, PuTTY is recommended

Setup

Preparation of the USB to Serial cable

The Turbine station has a TTL level serial interface which we need to connect to during the upgrade process. For this purpose a USB to Serial converter cable can be used. Recommended cable is TTL-232R-3V3 from Farnell.

This cable needs to be slightly modified as per photo below:

• Pin 1 = Black (GND)
• Pin 2 = Orange (Turbine RX)
• Pin 3 = Yellow (Turbine TX)

Original cable

Modified cable

Insert the USB connector in the PC. The unit will now install itself. Make a note of which COM port it becomes. You will also find the device in the Device Manager.
