March 22, 2022 – New bootloader V3.0 for KOLIBRI: Sending in a KOLIBRI controller for service is history

With the new bootloader, sending in a KOLIBRI controller for service in case of an unintentional interrupted or incomplete update is history!

In order to use the new bootloader, the new controller software V3.0 must be installed on the KOLIBRI. Then the bootloader update to V3.0 must be performed as described below. The new bootloader is not backward compatible.

1. Update firmware as usual with the ProgUNIT.
2. When the update is complete, disconnect and reconnect the drive battery.
3. Program the mode 1.
4. Disconnect the drive battery and reconnect it.
5. Wait until the controller initializes.
6. Press and hold the button until the controller beeps (this may take several seconds). The beep of the bootloader update differs from that of the mode programming and is therefore easily recognizable.
7. Disconnect the drive battery and reconnect it. The controller then initializes and is ready for the user-defined setting.
8. For control purposes, the controller software V3.0 and Bootloader V3.0 are now displayed in K-Config V1.3.11.
