Hello engineers,

We trying to debug/program a lpc1114/333 but there is something wrong and we are out of ideas. We use the simple led blinky example. When programming the chip with SWD everything seams to be ok even after verifying. When we start the debug session in LPCXpresso the status change in running but the debug led is not blinking. When pauze the debugging we can't step through the program. when switching the power off and on the led starts to blink.

-The bootloader pin is high

We use the internal oscillator
