Which means your question is probably of topic for u-boot list. Check a
general embedded programming list.
To get you started, you will have to do some of the cpu/board
initialization done u-boot in your code before you can flip that LED
which could be as short as a few instructions that modify a specific
memory location or significantly more complex routines depending on how
the LED is interfaced.
Your CPU manual and board schematics and datasheet/user guide of the
parts on the board and crafty use of google are your friend. You need to
know some assembly programming for your CPU and be comfortable debugging
via BDI debugger.
