AD9522 Evaluation Software Installer (Rev. 2.1.0)
This installer contains USB drivers that are both 32- and 64-bit compatible. Note: Older AD9520 evaluation boards will need to have the USB controller EEPROM re-flashed in order to use this driver.
7.35 M
Evaluation Board USB Flash Programmer
Contains the EXE file for re-flashing the USB EEPROM.
AD9522 Evaluation Board USB Flash Programmer Readme
EVB flash readme: This file contains instructions for re-flashing the USB controller on an older eval board so that the evaluation board is compatible with the newer 64-bit USB driver. The USB driver is also 32-bit compatible.
