To update the firmware on all YachtBot hardware, you will need a mirco-USB cable and a copy of the YachtBot firmware - see "The latest firmware" at the end of this page.


**Warning**

  • THIS PROCESS MUST NOT BE DONE ON A MAC. Windows or Linux only.
  • Updating firmware on any device carries risk of damage. Firmware should only be updated on an as-needs basis under direction from Igtimi staff.  


Firmware update process

  1. Download and unzip the correct zipped folder from the links at the bottom of this document, based on the hardware type being updated.   
  2. Remove the water proof plug from the bottom of the device and plug the micro-USB cable into the YachtBot Mirco-USB socket.
  3. Plug YachtBot into a computer via USB. The YachtBot power light light comes on. 
  4. Within a couple of seconds, give the YachtBot power button a short press. All lights start flashing and the device will appear as a USB flash drive
  5. Open the mounted drive on your computer and delete the file called "firmware.bin"
  6. Stop, take a breath and say after me "I have deleted the file!", because this is important.
  7. Drag and drop, or copy and paste the new firmware image onto the removable drive – it doesn’t matter what the new firmware file name is as long as it is the ".bin" file from the unzipped downloaded folder.
  8. Wait for the file copy to finish, and then unplug the USB cable.
  9. The YachtBot device starts up for a few seconds, then shuts down.  You're DONE! The new firmware has now been installed.
  10. Proceed to update the configuration as outlined below.

Notes

  • TideBot users: remove the bottom lid of the TideBot pod for access to the USB port, and use the magnetic switch to "press" the power button
  • After updating firmware,
  • Here is what you should see on the mounted drive.  If you can see *.bif, *.log and config.ini files, then you have missed pressing the button in time.  In this case, pull out the cable and wait for the lights to turn off before starting again.


Configuration update and _assets folder

Version 417 requires a new config.ini file and _assets folder installed.  Ensure the config.ini file and _assets folder from the downloaded zip file have been copied to the SD card.  Instructions can be found here...

Firmware recovery procedure

Should a firmware update fail for any reason, then YachtBot will lock on with the power light illuminated and be unresponsive to button presses. A new firmware image can be loaded using the following procedure.

  1. Plug in the USB cable 
  2. Press and release the reset button (small white pin-hole next to the power socket) 
  3. Proceed to step 3) above
