5.5 Updating the MCU firmware

New MCU firmware and corresponding tool versions may be released e.g. to support new features or
to increase the performance of the application. To update the firmware, the following equipment is
required:
• Silicon Labs IDE or Flash Programming Utilities software [6], and
• USB debug adapter for 8-bit MCUs [7]
Follow these steps to flash the new firmware:
1. Power up the device.
2. Connect the debugger to the 10-pin rear connector.
3. If using the Silicon Labs IDE:
a. Select Debug > Connect to connect the Debugger to the MCU.
b. Select Debug > Download
c. Select Download to start the flashing process.
4. If using Flash Programming Utilities, follow the instructions accompanying the software.
5. After the device is flashed, disconnect the debugger and reboot the device.
6. Confirm that the firmware version string matches by either checking what the MCU outputs
during bootup, or by sending a FW GET command.
