failed to read firmware from eeprom

I am using the AD96 TOF board with Dragonboard 410c, I have connected a display and mouse+keyboard to the dragon board. I see the error Failed to read frirmware from eeprom in the terminal when I try to run the aditof-demo.sh

I have updated the sdk on the sd card following the build instructions here https://github.com/analogdevicesinc/aditof_sdk/blob/master/doc/dragonboard410c/build_instructions.md

Although I was able to run the aditof-demo.sh initially on the dragonboard, I then attempted to connect the dragon board over USB to PC and run the aditof-demo on a linux PC where the eeprom firmware error first showed up, Reverting to the dragon board setup I see the same issue while trying to run the aditof-demo on the dragonboard now. 

Please help me with any leads on how I can identify what is missing at my end which could be creating this issue?, I have tried running the eeprom tool which returns segmentation fault.

     , do any of the command line outputs point to any leads on why I could be facing this issue? is there a way to check if there is an issue with the eeprom on the board itself or its just a software issue?

    My concern is that the demo was running fine when I first connected and booted the 410c board, only after I tried to connect to a linux PC I have run into this issue. Let me know if I could share any other detail that could help debug this issue.

    It looks like the content of the EEPROM is now corrupted and that is why it can't read the intrinsics or the firmware. The size of the EEPROM (64940 bytes) seems to be the correct size. I can't figure out what could have altered the EEPROM content.

    We will think of something and get back to you.
