5.2.1 Debug On-Board
The on-board debug functionality is provided using Renesas S124 Debug MCU and SEGGER J-Link
®
firmware. Debug USB Micro-B connector (J10) connects the S124 Debug MCU to an external USB Full
Speed Host, allowing re-programming and debugging of the target RA MCU firmware. This connection is the
default debug mode for the EK-RA6M5 board.
The S124 Debug MCU connects to the target RA MCU using the SWD interface.

A yellow indicator, LED5, shows the visual status of the debug interface. When the EK-RA6M5 board is
powered on, and LED5 is blinking, it indicates that the S124 Debug MCU is not connected to a programming
host. When LED5 is on solid, it indicates that the S124 Debug MCU is connected to a programming
interface.
