AD9528/PCBZ (Rev C) connection problem

When I install the AD9528 Eval software (v. and connect the power and USB connectors it is recognized in the windows device manager, but the eval software says "No Hardware Connected" in the bottom left. The board is still not recognized after clicking File-> Select Hardware -> Refresh.

Has anyone else had problems connecting to this eval board?

For reference:

  • I am using a Windows 10 PC, but I have also tried on a Windows 7 PC with the same results.
  • When the barrel plug is connected LEDs DS4 and DS3 turn on.
  • When the USB is connected CR300 turns on and CR2 begins blinking,

    I also have Windows 10 on my PC. I took an AD9528 evaluation board, supplied it and then connected it to my PC using the USB cable. In the Device Manager, the board appears as such:

    Please make sure your PC shows it as well.

    DS4 LED tells you there is 3.3V supply on the board.

    DS3 LED is also on on my board. It tells you that the RESETB pin of the AD9528 is high, which is good.

    You should see the CR300 LED also turned on after you connect the USB cable because this LED tells you RESETB pin of the AD9528 is high.

    CR300 being ON is also good, because it tells you the VBUS of the USB is on.

    CR2 blinking tells you the enumeration between the PC and the board has been done and the PC has access to the USB chip on the board.

    After you launch the evaluation software, you should see this in the bottom left corner,:

    This means the evaluation software has connected to the board.

    I made a photo of my board. Check the jumpers you have on your board to match the ones on this board.


  • Hi,

    Thanks for your reply. My PC shows the same name in the Device Manager and I have verified that all the jumpers are in the correct positions, but the eval software still will not connect.

    the bet here is that you have an old AD9528 evaluation board that had an EEPROM on it compatible with older versions of Windows.

    If this is the case, in the following I'm describing how to update the EEPROM to make it compatible with the latest Windows releases. Newer versions of the boards should work without any problem (I have rev E board)

    Please go to this website:

    Download the zip file or the exe file of USBEvbdProgrammerSetup and install it on your PC.

    On the board:

    - take out P1 jumper to enable the EEPROM programming

    - make sure P303 jumper is mounted, so the EEPROM can be accessed by the USB chip

    - connect the PC to the board and supply the board

    Launch the USB Evbd programmer.

    You should see Cyusb-1 in the Select USB Device to Program. If do not, I do not know what is going on. It must be a PC problem that I do not know.

    Then select AD9528 Eval Board (32/64 bit) from the drop down menu of the Select Evaluation Board Identity.

    Click Program EEPROM. In the Details window, the program should tell you that the programming has been done and you should cycle power the board in order for the new EEPROM to be used.


  • Hi Petre,

    I see Cyusb-1 in the Device to Program option. I have removed the P1 jumper and ensured that the P303 is placed. When I press "Program EEPROM" I get the following error message:


    When I press "Read EEPROM" I see this:

    It looks to me like the board was incorrectly programmed with the wrong board identity (AD9507 instead of AD9528). I am 100% sure that the positions of the jumpers match the picture you sent earlier, with the exception of P1 being removed. Do you know why I can't reprogram the EEPROM?

    I'm sorry for all this trouble. I should have said to insert jumper P1. I'm sorry for this. 

    This is the schematic of the EEPROM. When P1 is inserted, WP is connected to ground, enabling the write into EEPROM.

    When the jumper is taken out, the WP pin is high, enabling the write protect.
