3.7 Debug Adapter
BRD8010A STK/WSTK Debug Adapter is an adapter board which plugs directly into the debug connector and the Simplicity Connector
on the mainboard. It combines selected functionality from the two connectors to a smaller footprint 10-pin connector, which is more
suitable for space constrained designs.
For versatility, the debug adapter features three different 10-pin debug connectors:
• Silicon Labs Mini Simplicity Connector
• ARM Cortex 10-pin Debug Connector
• Silicon Labs ISA3 Packet Trace
The ARM Cortex 10-pin Debug Connector follows the standard Cortex pinout defined by ARM and allows the Starter Kit to be used to
debug hardware designs that use this connector.
The ISA3 connector follows the same pinout as the Packet Trace connector found on the Silicon Labs Ember Debug Adapter (ISA3).
This allows the Starter Kit to be used to debug hardware designs that use this connector.
The Mini Simplicity Connector is designed to offer advanced debug features from the Starter Kit on a 10-pin connector:
• Serial Wire Debug (SWD) with SWO
• Packet Trace Interface (PTI)
• Virtual COM port (VCOM)
• AEM Monitored voltage rail
Note:
Packet Trace is only available on Wireless STK Mainboards. MCU Starter Kits do not support Packet Trace.
