 Hi, my name's Jim Barlow with ST in the NFC RFID Marketing Department and I'm going to show you how to overcome a couple of errors that may happen when you're evaluating your ST25R3911B discovery board. Perhaps you've acquired this board to evaluate the ST25R3911B IC itself as a reader or perhaps you're using the features of the GUI in the tag editor to evaluate the ST25DV dynamic tag. To find the discovery GUI from the ST home website there's a shortcut you can type www.st.com.nfc. This will take you to the home landing page for all the ST NFC products. If you click on the NFC RFID Reader section it will bring you to the full selection of ST NFC RFID Readers. To go down to the ST25R3911B select that product and from the quick toolbar select tools and software and under tools and software you find the PC software installer for the ST25R3911B discovery board and simply click get software. Accept the license agreement and download to your machine. Once you've downloaded and installed the ST25R3911B discovery GUI the first step you want to do is the demo board check. This is where you can encounter an area where the version mismatch of the GUI and the code in late loaded on the discovery board do not match. This is really simple to resolve this error and I will take you through this process. First click OK then under the help menu select help and then scroll down to firmware update select firmware update it will take you automatically to the path where the hex file is located that needs to be updated on the discovery board select that select open you'll see in the bottom left here the steps where it is successfully updating erasing the firmware at this step and now it's doing the upgrade upgrade was successful please reconfigure the device before continuing now at this point you can do the demo board check calibrate the antenna and adjust the regulators and you're ready to enjoy using your discovery board. Another error that you may encounter when doing your firmware upgrade is an incompatibility with your USB driver on your PC machine. If this error occurs as on this slide in the upper left you will see the above error messages and will continue to retry without success. This is an indication that you need to load a new boot load driver on the bottom part of this slide you can see the path under program files ST microelectronics ST25R3911B discovery GUI and if you follow out to Windows 7 and 64 bit machine you will find the file called dp install amd64.exe simply click on that file execute it and it will update your USB driver so that your machine will talk correctly to the discovery GUI board now that you've had a successful install of the ST25R3911B discovery GUI you can begin debug of either your ST25R3911B reader or with the new ST25 tag editor feature you may be doing debug of any of ST's NFC tags whether they're type 4 or type 5 tags enjoy use of your new tool and thanks for designing with ST.
