TPS65988EVM: Error when trying to re-flash EVM FW (Recovery)

Part Number: TPS65988EVM

Hello, 

I am trying to re-flash my TPS65988 EVM back to its original state using the re-flash EVM firmware button. However it seems that I run into an error when I do this. 

  • When I run this command EVM should be flashed with firmware that matches the "out of the box" firmware, is my understanding correct? 
  • Its not clear to me what the error means, does TI know what could be goin on here? 

Thanks,

Matt

    Hi Matt, 

    Thank you for reaching out!

     I also encountered the same error. But there is another way to achieve this: 

    1- Go to new project ---> select the TPS65988 

    2- Go to Binary --> Flash Erase (This should return successful) 

    3- Go to Binary --> Flash from Current Project (This may say that the region offsets are invalid but click "OK" and this should return successful)

    Also, we have a newer release of the GUI (6.1.4): https://www.ti.com/tool/TPS6598X-CONFIG

    Please let me know if this works! 

    Best Regards, 

    Aya

    HI Aya, 

    Thank you for the help here. I suspect that there is an issue with my board itself. After reflashing the FW like you described I can see that the VBUS LED for port B lights up when I mate a usb drive to the usb-c receptacle but port A doesn't show the same behavior. Looking at the CC pins for each port, port A is always low and port B seems to be showing the CC logic. 

    I measure 80ohms to ground on the port A CC pin as well. 

    Do you think there is a HW issue here? 

    Thanks,

    Matt

    Hi Aya, 

    I ordered a second EVM and I have no issues with flashing the device or connectivity with either of the USB-C receptacle. 

    Thanks,

    Matt
