We recommend to use the firmware 2.0, which has a more stable code, more supported communication interface and allows working with Linux and MacOS. Additionally, most of the tools provided in this website require the firmware 2.0 to work properly.

Upgrade to OHC Firmware 2.0

Most of the information reported here below come from (and can be found also on) the kilobotics website (https://www.kilobotics.com/documentation).

We recommend doing the firmware upgrade from a Linux machine.

Here below, the steps to upgrade the kilobot firmware:

1. Setup of your Linux machine installing avrdude. For Ubuntu, use the following command:

sudo apt-get install avrdude

2. Download the file controller.hex

3. Set the OHC jumper to "internal" mode as in this Figure

4. Connect the OHC to the PC through Usb

5. Run (from the directory containing the controller file) the update command:

sudo avrdude -p m328 -P usb -c avrispmkII -U "flash:w:controller.hex:i"

6. If you succeed, the terminal message should say: Fuses OK. avrdude done. Thank you. Similarly to this screenshot.

Troubleshooting

1. Problem: Your system does not have the module m328 to update the kilobot firmware.

    Solution: Edit the file /etc/avrdude.conf and add at the end of the file the text of this file: avrdude.conf.m328

Firmware 1.0

In case needed, here you can get the firmware 1.0 (from K-team): OhcFirstFirmware.hex
