Why can't it often bootup(figure1 and figure2 are the same board)? why can't load MSS data and DSS data(figure1)?

    Hello,

    Could you providesome more information?

    1. Are you using the IWR1642BOOST EVM or a custom PCB?

    2. If using the IWR1642BOOST EVM, is it an ES1.0 or ES2.0?

    3. Which set of of binaries is flashed in the QSPI flash? (If they are from the mmWave SDK, which file was flashed and what is the version of the SDK that it was taken from?)

    4. What power supply is powering the board? Is it rated to supply at least 2.5Amps? Can you try a different power supply to see if it makes a difference?

    Regards,
    John
