11 Debugging
11.1 Debugging during battery operation
2010-04-09 - REVISION
The EFM32-G8XX-STK has an on-board debugger, and it can be used in different ways to debug the
EFM, both on and off kit. Below are descriptions on the different modes. Check the configuration chapter
to find out how to change the debug setting.
Table 11.1. Debug modes
When the EFM is powered by the battery (i.e. the USB is disconnected), the on-board debug functionality
is not available. To enable debugging in this mode, connect an external debugger (e.g. another EFM32-
G8XX-STK) to the debug pads in the bottom right corner of the EFM32-G8XX-STK. These pads are
connected directly to the EFM32 debug interface.
Note
Mode
Debug MCU
Debug IN
Debug OUT
When the on-board debugger is active, a current of approximately 1.6uA will be added to the
AEM measurements.
Description
In this mode the on-board debugger is connected to EFM on the EFM32-G8XX-STK.
In this mode the on-board debugger is disconnected, and an external debugger can be connected to
debug the EFM on the EFM32-G8XX-STK.
In this mode the on-board debugger can be used to debug an EFM mounted in your own application.
