5.4 Setting Up Debug Connection between the EK-RA4E2 Board and Host PC
To program the modified Quick Start example project on to the EK-RA4E2 board, a debug connection is
necessary between the EK-RA4E2 board and host PC.
1. Disconnect the USB cable from micro-AB USB Full Speed port (J11) and connect it to micro-B USB
debug port (J10) of the EK-RA4E2 board.
Note: The EK-RA4E2 board supports 3 debugging modes. In this section and the following sections, default
debugging mode, Debug On-Board, is used. More information on debugging modes is available in
EK-RA4E2 user’s manual.

2. Verify that the debug LED (LED5) stops blinking and lights up orange indicating that the J-Link drivers
are detected by the EK-RA4E2 board.
Note: The debug LED (LED5) continues to blink when J-Link drivers are not detected by the EK-RA4E2
board. In that case, make sure that the EK-RA4E2 board is connected to the host PC through the
micro-B USB debug port (J10) and that J-Link drivers are installed on the host PC by checking in the
Windows Device Manager (expand Universal Serial Bus controller, and locate J-Link driver).
