- f091.bin – firmware for the F103
- r103.bin – firmware for the F091
- nrf5.bin – firmware for the nRF51

- kooka_rp2040_mboot.uf2 – main application firmware
Kookaberries (Rev 4.05)
To install or update update the firmware on current Kookaberries (V4.05)
-
Plug the device into USB and it should appear as a mass storage device on your PC. If the blue LED is blinking once every second then the FEP is in recovery mode, otherwise it is in normal mode. In both cases files can be copied to the device for an upgrade.
-
Copy f103.bin, f091.bin, nrf5.bin to the root of the drive.
-
Unplug and re-plug the device from USB.
-
The blue LED should flash for about 30 seconds while it programs the F103, F091 and nRF51.
-
Once the blue LED stops flashing the device should be ready to use.
