      • I was trying to follow this tutorial:https://www.hackster.io/taroyoshino007/get-started-with-tensorflow-lite-micro-by-sony-spresense-e92bf1

      • But, was stuck on flashing a .bmp image to Spresense for on-device model inference. Which, I wasn't able to use the xmodem_writer.exe provided from (https://github.com/sonydevworld/spresense/blob/master/sdk/tools/windows/xmodem_writer.exe)

      • I tried using flash_writer.exe, and it worked until this Message...

      1862 bytes loaded.
      Key not specified.
      updater# >>> Save Configuration to FlashROM ...
      set bootable M0P
      M0P is not valid bootable. config not changed.
      updater# sync
      updater# Restarting the board ...
      reboot

      • Any solutions?
