=== ChipWhisperer-Lite (CW1173) with 909-LPC-P1114 Development Board ===
To allow the ChipWhisperer-Lite to interface with this board, we'll need to make some small modifications to the board:
# Short jumper BLD_E to put the device in bootloader mode.# Solder a wire from GND to P0_3 (Second column from the left, fourth row from the bottom) to put the bootloader in UART mode.# Remove C1 and C4 from the board.# Cut the traces on 3.3V_CORE and 3.3V_IO_E.# Add a 12-ohm resistor on the 3.3V_CORE jumper.# Add an SMA connector to the board and connect Vcc to the center pin and GND to one of the outside pins(or just use a jumper instead of fancy SMA).
# Add a header pin/wire to RST (First column from the left, third row from the bottom). The CW-Lite needs two connection points, as we'll be both resetting this pin and triggering off of it.
The following shows the required modifications (clock for full size):

Next, we'll need to connect the CW-Lite to the connect pins on the dev board to pins on CW-Lite's 20 pin header:
# Connect pin 1 of UEXT (Vcc) to pin 3 on the CW-Lite
