    Thanks for your help


    • P.S. My operating system is Win 10. There is only one driver name under my device manenger list.

  • Hi Yangkai, 

    You will have to update to the latest version of Bootloader for Windows 8/10 support.

    You can download the latest version of Bootloader update application from the following location on P&E website:

    Also, Erich Styger did a great job describing the overall Bootloader update procedure on his blog:

    Unfortunately, you do have to use a Windows XP or Windows 7 PC to perform this update.

    Best Regards,

    • Hi Zahar
      Thanks for your reply, I found an windows 7 computer and upgrade the bootloader and application version. My problem is solved. Thanks anyway!

      Best regards

  • Hi Yangkai, 

    Glad that you have your OpenSDA board up and running.

    Best Regards,
