    hi Kasket
    After extraction of your flashstream files, were you able to still communicate with the guage? At what point did the gauge stop commucating? What is the set up for programming your OTP. Can you describe? Are you following the instructions for OTP programming as listed in the TRM?

    thanks

    Hi Onyx,

    I am using EV2400 and SmartFlash is also detecting gauge but when I am trying to flash .ot.fs, it is failing.

    In logs it is showing NAK after I2C write operation).

    We have made setup to target board and EV2400 as mentioned in TRM  and i am following each and every step defined in TRM for flashing .OTFS file.
