Upgrading Firmware-Windows

Upgrading Firmware – Windows

Preparation

  • Download the firmware of your choice from Yujin’s fileserver onto your PC.
  • Download the flashing tool for Windows into the same directory.
  • Turn off the robot (switch on the side).
  • Switch from normal runtime mode to firmware download mode.

This simply changes the type of data that is sent back and forth along the usb connection. You can do this by moving the switch illustrated below into the ‘download’ (up) position. Note that this switch is embedded into the robot cover so it isn’t easily thrown by accident – you may need thin plyers or some similar tool.

Connect the robot to your PC using the USB cable.
Turn on the robot, give it time to boot up.

Flashing

Locate the serial port of the Kobuki. I have serial port as COM1. Then launch the ST Flash loader demonstrator. Then set the properties as shown in the figure below.

Then just press the next button. At this moment you may see below figure. It means that your Flash loader detects the your Kobuki.

Then press “Next” again. You will see the figure below. Choose “Download to device ” and select the new Kobuki firmware file. Note that a file extension is hex

Press the Next button again. You will see download page as below:

If there is no problem, you can see the “successfully downloaded flag” as above.

Rebooting

  • Turn off the robot power
  • Flick the firmware switch back to ‘Operation’ mode.
  • Turn on the robot power
  • Be happy!

Troubleshooting
