5.1 USB MCU
5.1.1 Bootloader
The USB controller is programmed with a bootloader when it is shipped from the factory. The
bootloader allows programming of new code into the USB MCU without the Silicon Labs’
serial adapter. The bootloader communicates with SmartRF
®
Studio or a custom program via
USB.
5.1.2 Programming USB controller
If it is required to update the firmware of the USB MCU, this can be done using the
SmartRF
®
04 programming software (Chipcon Flash Programmer or SmartRF
®
Studio). For
use of Chipcon Flash Programmer please refer to Chipcon Flash Programmer user manual
for instructions. The USB controller can only be updated via USB when no EM is connected to
the SmartRF
®
04EB.
To download firmware to the USB MCU without using the bootloader or to download the
bootloader in the first place, a Silicon Labs’ EC2 serial adapter (Figure 2) is required. This
adapter should be connected to P301, marked “USB MCU debug”, on the SmartRF
®
04EB.
