Figure 88 LPCXpresso IDE Program Flashing in Progress
In case flashing fails, an error message like below will be displayed. This is an indication that the
debugger could not connect to the LPC111x. The most common reason is that the microcontroller is in
a low-power mode where the debug connection is disabled. Make sure the microcontroller is in
ISP/bootload mode and try again. This is accomplished by pulling pin PIO0_1 low (via 100-1000 ohm
resistor to ground).
