11 Updating the firmware
Updating the EB firmware is done automatically by SmartRF Studio and SmartRF Flash
Programmer if an old or incompatible firmware version is found on the USB MCU. SmartRF Flash
Programmer also allows manual programming of the EB firmware. Please refer to the respective
user’s guides for detailed instructions. A simple step-by-step guide for updating the USB MCU
firmware using SmartRF Studio is provided below.
1. Turn off the evaluation board (EB).
2. Disconnect any connected evaluation module (EM).
3. Plug in the USB cable and turn the power switch on.
