* DESCRIPTION
*  This is the startup file. The cyg_user_start function
*  is used to setup from eCos and the main function is called
*  as the first thread from eCos when the scheduler is started.
*  The main thread starts with a priority of 10.
*  Main is responsible to initialize the rest of the system
*  and to start all other threads.
