5.4  Setting Up Debug Connection between the EK-RA4M2 board and Host PC 
To program the modified Quick Start example project on to the EK-RA4M2 board, a debug connection is 
necessary between the EK-RA4M2 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-RA4M2 board. 
 
Note:  The EK-RA4M2 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-RA4M2 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-RA4M2 board. 
 
Note:  The debug LED (LED5) continues to blink when J-Link drivers are not detected by the EK-RA4M2 
board. In that case, make sure that the EK-RA4M2 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).
