The harder you work,
           the luckier you seem to be.  

This is a simple “blinky” application, cross-compiled on a Linux host using gcc for an Intel Xscale (ARMv5te) based single board computer with no run-time support (bare metal).
LEDs (r-off, y-on, g-on) with rs232

This application demonstrates the following technologies;
Multi-threading (Posix), Concurrency Control (mutex), Device Drivers (push buttons, leds), an Interrupt Service Routine (SIGINT), a Timer (SIGALRM) and TCP/IP client-server networking.
