TPS65987EVM: Always getting SPI FLASH to Device Failed Verification error on loading image

Part Number: TPS65987EVM

I have followed 

https://e2e.ti.com/support/interface/f/138/p/727037/2684338?tisearch=e2e-sitesearch&keymatch=tps65987%20verify#2684338

to downgrade the FTDI drivers to 2.8.2.  When I plug the EVM in, the device is recognised as 4 x serial ports as expected.

However I cannot load any images onto the board.  

I have two boards and I think one is now corrupt as I cannot plug any USB C device in and get that device to charge.  

I've tried programming the recovery image and that does not work either,

Windows 7, 64 bit.

Going to try a Windows 10 machine at a different location.

    Hi Andy,

    What version of the GUI are you using? Do you have other versions of the GUI installed? There has been work done since the post you reference to increase stability.

    I recommend using the FTDI driver packaged with the GUI, especially if you are having drive issues. I think checking with a Win 10 machine connecting directly (no hub or docking station) is a good plan. I also recommend testing by installing the GUI and selecting both Install FTDI Driver and Remove Previous versions.

    Another work around is to use a dedicated I2C/SPI programmer such as the Aardvark from TotalPhase.

    Regards,
    Scott

    Hi Scott, the GUI version is 5.13.

    I had no success using Windows 10, 64bit, but that was with a board I may have corrupted,  I will try an eval board that I think is working with the Windows 10 machine tonight and update this post then.

    On my Win 7 machine I will carefully un-install all previous FTDI drivers and re-install using the ones from the downloaded package. 

    Thanks Andy

    I think I have resolved the problem, I have re-installed the TI supplied drivers. I was still unable to flash the EVM firmware, but I could use the debug modes to prove the FTDI drivers were working.

    I then re-loaded a project I had (which limits the PD source voltage to 9V) and was able to flash that and the board which i thought I had corrupted now works.

    In addition I proved I could now re-flash the EVM image.

    Strange ...
