8. On-Board Debugger

The Wireless STK Mainboard contains an integrated debugger, which can be used to download code and debug the EZR32. In addition
to programming a target on a plug-in radio board, the debugger can also be used to program and debug external Silicon Labs EFM32,
EFM8, EZR32 and EFR32 devices connected through the debug connector.
The debugger supports three different debug interfaces for Silicon Labs devices:
• Serial Wire Debug, is supported by all EFM32, EFR32 and EZR32 devices
• JTAG, is supported by EFR32 and some EFM32 devices
• C2 Debug, is supported by EFM8 devices
In order for debugging to work properly, make sure that the selected debug interface is supported by the target device. The debug con-
nector on the board supports all three of these modes.

8.1 Host Interfaces

The Wireless Starter Kit supports connecting to the on-board debugger using either Ethernet or USB.
Many tools support connecting to a debugger using either USB or Ethernet. When connected over USB, the kit is identified by its J-Link
serial number. When connected over Ethernet, the kit is normally identified by its IP address. Some tools also support using the serial
number when connecting over Ethernet, this typically require the computer and the kit to be on the same subnet for the discovery proto-
col (using UDP broadcast packets) to work.

8.1.1 USB Interface

The USB interface is available whenever the USB Mini-B connector on the left hand side of the mainboard is connected to a computer.

8.1.2 Ethernet Interface

The Ethernet interface is available when the mainboard Ethernet connector in the top left corner is connected to a network. Normally,
the kit will receive an IP address from a local DHCP server, and the IP address is printed on the LCD display. If your network does not
have a DHCP server, you need to connect to the kit via USB and set the IP address manually using Simplicity Studio, Simplicity
Commander or J-Link Configurator.
For the Ethernet connectivity to work, the kit must still be powered through the USB Mini-B connector. See
for details.

8.1.3 Serial Number Identification

All Silicon Labs kits have a unique J-Link serial number which identifies the kit to PC applications. This number is 9 digits, and is nor-
mally on the form .
44xxxxxxx
The J-Link serial number is normally printed at the bottom of the kit LCD display.
