ADCPro Can't Connect to ADS8881EVM-PDK

Other Parts Discussed in Thread: ADCPRO

Whenever I try to load the ADS888XEVM module in ADCPro, it either fails when it tries to download firmware to the board, or after that step when it tries to communicate with the DSP and times out. Attached are the message windows that I get. Has anyone experienced this, and have a fix or workaround for it?

    Hi Jason,

    During software installation, it is possible for windows to block driver installation depending on user privileges and/or too restrictive configuration settlings.

    Try installing the mmb0 driver from the following link before running ADCpro:
    ftp://ftp.ti.com/pub/data_acquisition/ADCPro2/misc/drivers/64bit/mmb0_driver_install_x64-v1.0.0.0.msi

    If the file above doesn’t work, it is better to disable windows “driver signature enforcement” all together to make sure the driver installs properly. For this, do the following:
    1) Restart you computer and before the windows loading screen appears press F8 several times. This should take you to the following screen:


    2)   With the keyboard, select “Disable Driver Signature enforcement” and press ENTER
    3)   Wait for windows to load
    4)   Reinstall the ADS888xEVM software (ads888x-adcproplugin-1.0.0.exe) and click “install anyway” when windows asks about driver installation
    5)   Make sure the EVM is properly powered and configured as specified in the Users’ Guide
    6)   Run ADCpro and the EVM should run properly

    Regards,

    Hi Rafael,

    I uninstalled both the MMB0 and ADS888x drivers, and then reinstalled the mmb0_driver_install_x64-v1.0.0.0.msi after rebooting and disabling the driver signature enforcement. Seems like it installed just fine. I then tried to reinstall the ads888x-adcproplugin-1.0.0.exe, and got the following error during the USBStyx driver installation:

    I've seen this issue on the forums before, has a definitive solution been found?

    Regards,

    Jason

    Hi Jason,

    I was finally able to replicate the issue. The libusb0.dll file should be copied to several locations, but one is somehow missing.

    Try the following:

    1) Run again the mmb0_driver_install_x64-v1.0.0.0.msi

    2) Download the ZIP file from the following link
    6406.lib.zip
    Extract the libusb0.dll file to:
    C:\Windows\System32\

    3) Run the ads888x-adcproplugin-1.0.0.exe

    4) Connect the EVM to the computer (make sure it is powered)

    5) Run ADCpro

    Let me know if this works.

    Regards,
    Rafael

    Hi Rafael,

    I copied the libusb0.dll to C:\Windows\System32\ and re-ran the ads88x-adcproplugin-1.0.0.exe successfully and without error!

    When I first powered up the EVM, connected it to the PC and loaded the plugin in ADCpro, it was still giving me the same messages that I originally posted (can't download the firmware and times out). I uninstalled ADCpro and deleted the folder in C:\Program Files (x86), then reinstalled ADCpro and the ads88x-adcproplugin-1.0.0.exe and everything seems to be working great!

    Thanks again for your support!
