/***********************************************************************
 * Example purpose
 ***********************************************************************
 This is a simple demo that demonstrates the use and function of the
 SDK7A404 startup code. The startup code sets up the board into an
 initial known state and then branches to the user application code
 at c_entry().

 The sdk7a404_simple_startup.c file contains an application that is
 called after the startup code is complete. The application simply
 starts the timer interrupt at a 10Hz rate, and blinks several LEDs
 on the SDK7A404.

 ***********************************************************************
 * Using the makefile
 ***********************************************************************
 Prior to building an image, the ABL package, LH7A404 CSP, and SDK7A404
 BSP, must of been prebuilt. If the libraries do not exist yet, a link
 error will occur.

 Build an executable image by typing:
     make (or make release)

 For ARM targets, an axf file and a bin file will be created.
 FOR GHS and GNU targets, an elf file and a bin file will be created.

 The generated bin file can be FLASHed into FLASH and is linked to be
 executed at address 0x00000000 on reset of the SDK7A404.

 A 'test' release can be built by typing:
     make test
 A test image is linked to execute at address 0xB0000000 in internal
 memory. For small images (of a total size less than 80Kbytes), this
 image can be built and loaded prior to building the release image
 and FLASHing it.
