A yellow indicator, LED5, shows the visual status of the debug interface. When the EK-RA4E2 board is
powered on, and LED5 is blinking, it indicates that the RA4M2 debug MCU is not connected to a
programming host. When LED5 is on solid, it indicates that the RA4M2 debug MCU is connected to a
programming interface.
To configure the EK-RA4E2 board to use the Debug On-Board mode, configure the jumpers using the
following table.
Table 6. Debug On-Board Jumper Configuration
Location
Default Open/Closed
Function
J6
Closed
Target RA MCU MD connected to debug
J8
Jumper on pins 1-2
Target RA MCU RESET# connected to nRESET signal
J9
Open
RA4M2 debug MCU in normal operation mode
J29
Jumpers on pins 1-2, 3-4, 5-6, 7-8
Target RA MCU debug signals connected to the debug
interface
Figure 10. EK-RA4E2 Debug Interface
5.2.2 Debug In
One 20-pin Cortex
®
Debug Connector at J20 supports JTAG and SWD debug. One 10-pin Cortex
®
Debug
Connector at J13 supports JTAG and SWD. Either of these connectors may be used for external debug of
the target RA MCU.
To configure the EK-RA4E2 board to use the Debug In mode, configure the jumpers using the following
table.
