Updating DocBrown

DocBrown firmware (internal operating software) can be updated by placing a special file on the SD card. For the procedure to work properly you must follow these instructions to the letter:

  • Extract the firmware file and rename it to “DocBrown.fw”
  • Place the file in the root folder of the SD card
  • Move the write protect tab at the side of the card to “Lock” position
  • Insert the card into DocBrown socket with Marty powered off
  • Power on the console, status LED will start blinking very quickly
  • Wait until LED blinking pattern changes to 1/2 second on, 1/2 second off
  • Power off Marty, remove the card, unlock the tab
  • Remove the file from the card to avoid accidental update

IMPORTANT: If at any time during firmware update status LED stays completly on or off, or blinks in unexpected pattern, it means an error has occured. Retry the procedure, use a different card if the problem persists.
