Software debug options
You can debug the software using the following two options in EVK-ANNA-B112:
•
Onboard debug solution available on the USB connector
•
An external debugger connected to J12 connector
An external debugger connected to the J12 connector is useful when powering the evaluation board
with the CR2032 coin cell battery, or through the external power supply connector J5. It could also
be useful in a scenario where the debug MCU interface has been disconnected from the ANNA-B112
module using the jumpers on J9 header. The SEGGER J-Link software [4] is required to debug using
the onboard J-Link hardware on the EVK-ANNA-B112.
