The main board with USB interface and a daughter board for external connection. The below picture is when the main board and daughter board is connected. TM On the main board, JP2 is used to enable OPTIGA Trust B device on the main board. On the daughter TM board, JP201 is used to enable OPTIGA Trust B device on the daughter board. There are two sets of pin header X201 and X202 on the daughter board, which can be used to either connect external TM OPTIGA Trust B devices or to probe the signal. The rest of the pin headers on the board are mapped to some of the commonly used external signals on the XMC controller. When the main board is plugged into the USB interface of the computer, a green LED should light up followed by running orange LEDs. That means the firmware in XMC controller is executed properly. If both LEDs cannot be observed, please plug out and plug in the main board to reset the firmare. Application Note 2 <Revision 1.0> <2017-01-01> Evaluation Kit User Guide PC GUI 2 PC GUI PC GUI can be downloaded from www.infineon.com/optiga (OPTIGATM Trust B Evaluation Kit). Upon running the executable file (OPTIGA Trust B.exe), below GUI should be shown on the desktop. Application Note 3 <Revision 1.0> <2017-01-01> Evaluation Kit User Guide PC GUI 2.1 Search devices on SWI bus The first step before running authentication or NVM operations is to identify the devices connected to the SWI bus, and then select the device to communicate. This can be achieved by clicking the button "Device Search". After clicking the button, at least one device unique ID should be displayed. The GUI supports maximum of two device unique ID to be displayed. Here is the example of two device unique IDs In order to select the device to communicate, simply check the radio button of the corresponding Device Unique ID and click button "Select Unique ID". After this, you should see SLE95250 displayed and "Enhanced Authentication" and "Non-Volatile Memory" button enabled as below picture. Application Note 4 <Revision 1.0> <2017-01-01> Evaluation Kit User Guide PC GUI Now you are ready to start authentication and NVM operations. 2.2 Authentication Click "Enhanced Authenticatin button, this brings you to the authentication GUI tab. Application Note 5 <Revision 1.0> <2017-01-01> Evaluation Kit User Guide PC GUI Simply click "Authentication" button on the left bottom of the GUI, the complete authentication sequence will be executed and displayed. Actual value of all the algorithm flow can be viewed in the edit box. If the authentication passes, "Authentic" will be printed, otherwise "Couterfeit" will be printed. Application Note 6 <Revision 1.0> <2017-01-01> Evaluation Kit User Guide PC GUI 2.3 Non-Volatile Memory Click Non-Volatile Memory brings you to NVM operation tab. The Unique ID (UID) is displayed with vendor ID and product ID decoded. Current value of life span counter is shown as well. The value of the counter can be decremented once at a time by clicking "Decrease" button. NVM read and write operation can be verified by "Read NVM" and "Write NVM" button. Application Note 7 <Revision 1.0> <2017-01-01> Evaluation Kit User Guide Test external devices 3 Test external devices External devices can be connected to X201 or X202 on the daughter board. JP201 needs to be shorted and JP2 is recommended to be left open to avoid confusion. By connecting to X201 or X202, the customer device can be searched by the GUI, proper Unique ID can be displayed, and NVM operation can be verified as well. However authentication test might fail due to mismatch of the key. In order to test authentication, a proper customer key and curve parameter needs to be loaded. This can be achieved by importing a configuration xml file. The default configuration xml file is located in the GUI folder, named config.xml. Edit the file so that proper customer specific curve parameter and public key is loaded. After editing, under file menu, select "Import Parameters" and select Config.xml in the GUI software folder to load the parameters.
