BSP Developer’s Guide, 6.0

On a well-designed board, the LEDs are addressable without having too many

processor or board registers configured and without very much additional bus

configuration. The LED code should be simple. The following is an example of C

source code for a simple LED system (you may also use LED code from your

reference BSP):

/* sysLed.c - Wind River 8260 User LED driver */

#include "copyright_wrs.h"
