4 Getting Started
Before connecting the SmartRF06EB to the PC via the USB cable, it is highly recommended to perform the steps described below.
4.1 Installing SmartRF Studio and USB drivers
Before your PC can communicate with the SmartRF06EB over USB, you will need to install the USB drivers for the EB. The latest SmartRF Studio installer [1] includes USB drivers both for Windows x86 and Windows x64 platforms.
After you have downloaded SmartRF Studio from the web, extract the zip-file, run the installer and follow the instructions. Select the complete installation to include the SmartRF Studio program, the SmartRF Studio documentation and the necessary drivers needed to communicate with the SmartRF06EB.
4.1.1 SmartRF Studio
SmartRF Studio lets you explore and experiment with the RF-ICs as it gives full overview and access to the devices’ registers to configure the radio and has a control interface for simple radio operation from the PC.
This means that SmartRF Studio will help radio system designers to easily evaluate the RF-IC at an early stage in the design process. It also offers a flexible code export function of radio register settings for software developers.
The latest version of SmartRF Studio can be downloaded from the Texas Instruments website [1], where you will also find a complete user manual.
4.1.2 FTDI USB driver
4.1.2.1 Install FTDI USB driver manually in Windows
If the SmartRF06EB was not properly recognized after plugging it into your PC, try the following steps to install the necessary USB drivers. The steps described are for Microsoft Windows 7, but are very similar to those in Windows XP and Windows Vista. It is assumed that you have already downloaded and installed the latest version of SmartRF Studio 7 [1].
Open the Windows Device Manager and right click on the first “Texas Instruments XDS100v3” found under “Other devices” as shown in Figure 1a.
Select “Update Driver Software…” and, in the appearing dialog, browse to <Studio install dir>\Drivers\ftdi as shown in Figure 1b.

Press Next and wait for the driver to be installed. The selected device should now appear in the Device Manager as “TI XDS100v3 Channel x” (x = A or B) as seen in Figure 2b. Repeat the above steps for the second “Texas Instruments XDS100v3” listed under “Other devices”.
4.1.2.1.1 Enable XDS100v3 UART back channel on Windows
If you have both “TI XDS100v3 Channel A” and “TI XDS100v3 Channel B” listed under Universal
Serial Bus Controllers, you can proceed. Right click on “TI XDS100v3 Channel B” and select Properties. Under the Advanced tab, make sure “Load VCP” is checked as shown in Figure 2a.
A “USB Serial Port” may be listed under “Other devices”, as seen in Figure 1a. Follow the same steps as for the “Texas Instruments XDS100v3” devices to install the VCP driver. When the
drivers from <Studio install dir>\Drivers\ftdi is properly installed, you should see the USB Serial Port device be listed under “Ports (COM & LPT)” as shown in Figure 2b.
The SmartRF06EB drivers are now installed correctly.

4.1.2.2 Install XSD100v3 UART back channel on Linux
The ports on SmartRF06EB will typically be mounted as ttyUSB0 or ttyUSB1. The UART back channel is normally mounted as ttyUSB1.
1. Download the Linux drivers from [2].
2. Untar the ftdi_sio.tar.gz file on your Linux system.
3. Connect the SmartRF06EB to your system.
4. Install driver a. Verify the USB Product ID (PID) and Vendor ID (VID).
The TI XDS100v3 USB VID is 0x0403 and the PID is 0xA6D1, but if you wish to find the PID using a terminal window/shell, use
> lsusb | grep -i future
b. Install driver using modprobe
In a terminal window/shell, navigate to the ftdi_sio folder and run
> sudo modprobe ftdi_sio vendor=0x403 product=0xA6D1
SmartRF06EB should now be correctly mounted. The above steps have been tested on Fedora and Ubuntu distributions.
If the above steps failed, try uninstalling ‘brltty’ prior to step 5 (technical note TN_101, [2]).
> sudo apt-get remove brltty

5 Using the SmartRF06 Evaluation Board
The SmartRF06EB is a flexible test and development platform that works together with RF Evaluation Modules from Texas Instruments.
An Evaluation Module (EM) is a small RF module with RF chip, balun, matching filter, SMA antenna connector and I/O connectors. The modules can be plugged into the SmartRF06EB which lets the PC take direct control of the RF device on the EM over the USB interface.
SmartRF06EB currently supports:
- CC2538EM SmartRF06EB is included in e.g. the CC2538 development kit.
Figure 3 – SmartRF06EB (rev. 1.2.1) with EM connected
The PC software that controls the SmartRF06EB + EM is SmartRF Studio. Studio can be used to perform several RF tests and measurements, e.g. to set up a CW signal and send/receive packets.

The EB+EM can be of great help during the whole development cycle for a new RF product.
- Perform comparative studies. Compare results obtained with EB+EM with results from
your own system.
- Perform basic functional tests of your own hardware by connecting the radio on your
board to SmartRF06EB. SmartRF Studio can be used to exercise the radio.
- Verify your own software with known good RF hardware, by simply connecting your own
microcontroller to an EM via the EB. Test the send function by transmitting packets from your SW and receive with another board using SmartRF Studio. Then transmit using SmartRF Studio and receive with your own software.
- Develop code for your SoC and use the SmartRF06EB as a standalone board without PC
tools.
The SmartRF06EB can also be used as a debugger interface to the SoCs from IAR Embedded workbench for ARM or Code Composer Studio from Texas Instruments. For details on how to use the SmartRF06EB to debug external targets, see chapter 7.

Never connect batteries and an external power source to the SmartRF06EB at the same time! Doing so may lead to excessive currents that may damage the batteries or cause onboard components to break. The CR2032 coin cell battery is in particular very sensitive to reverse currents (charging) and must never be combined with other power sources (AAA batteries or an external power source).
SWRU321A – May 2013
In addition to regular debugging capabilities using cJTAG or JTAG, the XDS100v3 Emulator supports a UART backchannel over a USB Virtual COM Port (VCP) to the PC. The UART back channel supports flow control, 8-N-1 format and data rates up to 12Mbaud.
Please see the XDS100v3 emulator product page [4] for detailed information about the emulator. The XDS100v3 Emulator is powered over USB and is switched on as long as the USB cable is connected to the SmartRF06EB and the main power switch (S501) is in the ON position. The XDS100v3 Emulator supports targets with operating voltages between 1.8 V and 3.6. The min (max) operating temperature is -20 (+70) ˚C.
6.1.1 UART back channel
The mounted EM can be connected to the PC via the XDS100v3 Emulator’s UART back channel. When connected to a PC, the XDS100v3 is enumerated as a Virtual COM Port (VCP) over USB. The driver used is a royalty free VCP driver from FTDI, available for e.g. Microsoft Windows, Linux and Max OS X. The UART back channel gives the mounted EM access to a four pin UART interface, supporting 8-N-1 format at data rates up to 12 Mbaud.
To enable the SmartRF06EB UART back channel the “Enable UART over XDS100v3” jumper (J5), located on the lower right side of the EB, must be mounted (Figure 7). Table 4 shows an overview of the I/O signals related to UART Back Channel.
Figure 7 – Jumper mounted on J5 to enable the UART back channel
Table 4 – UART Back channel signal connections
6.2 Power Sources
There are three ways to power the SmartRF06EB; batteries, USB bus and external power supply. The power source can be selected using the power source selection switch (S502) seen in Figure
8. The XDS100v3 Emulator can only be powered over USB. The main power supply switch (S501) cuts power to the SmartRF06EB.
