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.

    Can you try to read the contents of the eeprom using the eeprom tool?
    

    Firstly, make sure you build the tool by using the flag '-DWITH_TOOLS=1'. Ex: ''cmake -DDRAGONBOARD=1 -DWITH_TOOLS=1 ..'
    

    After building the project run the tool like this:
    

    ./eeprom-tool -m -r backup.bin
    

    If this runs ok please attach the bin here, else post here the output / error

    Thanks for the suggestion.
    

    I did run it and it worked after adding sudo to the command, I see the below  messages,

    I wasn't able to recover the EEPROM content.
    

    An option is to rewrite the EEPROM with another image.
    

    First thing to do is to update aditof_sdk to latest from master branch. Then use the eeprom-tool to rewrite the EEPROM. You can use the EEPROM content from this file: https://github.com/analogdevicesinc/aditof_sdk/blob/master/misc/ad-96tof1-ebz/ad96tof1_eeprom.bin
