5.2 Debug and Trace
The FPB-RA2E1 board can be programmed and debugged using the built-in E2 Emulator On-Board
debugger.
5.2.1 E2 Emulator On-Board
Debug USB micro-B connector (CN6) connects the E2 debugger to an external USB full speed host, allowing
re-programming and debugging of the target RA MCU firmware.
The E2 Emulator On-Board debugger connects to the target RA MCU using the SWD interface.

A green indicator, LED3, shows the visual status of the debug interface. When the FPB-RA2E1 board is
powered on, and LED3 is blinking, it indicates that the E2 Emulator On-Board debugger is not connected to
a programming host. When LED3 is on solid, it indicates that it is connected to a programming interface.
When LED3 is flickering, it indicates that data is being transferred between the E2 Emulator On-Board
debugger and the programming host.
