BMD-34x-EVAL User Guide

Rev 2.0

The Reset button is connected to the IC used for the J-Link interface by default. Pressing reset while
the interface IC is powered will caused a momentary reset signal on the nRESET output of the
interface IC, which is connected via solder jumper to P0.18 of the BMD-34x module. If the Reset button
is held down during power on, it will cause the interface IC to enter its bootloader mode, allowing
either Segger J-Link or mbed programmer firmware to be programmed.
When the Reset button is directly connected to P0.18, it can be used as a 5th user button or as a reset
button directly connected to the BMD-34x module.
Solder jumper J18 is used to connect P0.18 of the BMD-34x module to the nRESET net. nRESET is
connected to the interface IC and to the reset connections on the Arduino headers.
