LPC2129 board working or not

I tried to get my lpc2129 board to blink a led, but its seems not to execute my software. So i wanted to know one thing for sure:

if remove the BSL (boot strap loader) jumper and hit the RST button it should automatically execute te file no matter what?

If i tried to compare(download) my flash it constantly gives an error why is?

Thx Rhino
