        Hi @mikhailz

        nuttx.spk is located under spresense/sdk.

        Do you mean flash nuttx.spk using usb on the main board?

        Best Regards,

          Hi @kamiltomaszewski
          I meant where is located in the main board SPRESENSE.
          Perhaps is it 8MB spi flash?
          and yes, can I access to this area from user program (via usb)?
          Thank you

            Hi
            My answer to myself
            No, you can't.
            nuttx.spk + loader.espk+gnssfw.espk files are really flashed to spi flash 8MB
            (the 2nd half of it).
            But it is closed from unauthorized access.
            Process occurs after resetting and by UART commands in first loader mode
