On-Board Debugger
9. On-Board Debugger
The SLWSTK6061A contains an integrated debugger, which can be used to download code and debug the EFR32. In addition to pro-
gramming the EFR32 on the kit, the debugger can also be used to program and debug external Silicon Labs EFM32, EFM8, EZR32
and EFR32 devices.
The debugger supports three different debug interfaces used with Silicon Labs devices:
• Serial Wire Debug, is used with all EFM32, EFR32 and EZR32 devices
• JTAG, which can be used with some newer EFR32 and EFM32 devices
• C2 Debug, which is used with EFM8 devices
In order for debugging to work properly, make sure you have the approriate debug interface selected that works with your device. The
debug connector on the board supports all three of these modes.
9.1 Host Interfaces
The SLWSTK6061A 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.
USB Interface
The USB interface is available whenever the mini-B USB connector on the left hand side of the kit is connected to a computer.
Ethernet Interface
The Ethernet interface is available when the kit's 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 mini-B USB connector. See 5.2 Board Controller Power
for details.
Serial Number Identification
All Silicon Labs kits have a unique J-Link serial number which can identifies the kit to PC applications. This number is 9 digits, and is
normally on the form 44xxxxxxx.
The J-Link serial number is normally printed at the bottom of the kit LCD display.
