We are in the process of changing ADF435x software to a newer software platform. To use old boards with the new software requires a different EEPROM PID. This can be changed by unzipping the attached files.
Connect the relevant evaluation board to the PC.
Run EEPROM v103.exe,
Load the file RFG_CyUSB_B40D.hex to the board.
Verify that the board ID had changed from B403 to B40D.
