   Thanks, it doesn't have a simple single led, but it does have a "matrix" of sorts. It's a strange configuration, 5x5 led, but in 3 rows (anodes), and 9 columns (cathodes, with limiting resistor). On top of this, the layout/positioning is also strange (presumably due to board layout constraints).

   I was able to get leds blinking and serial output only after doing a full erase of the chip. Downloads to chip for boot or app "seemed" like they succeeded, but did not until after full erase.
