- * This project provides two demo applications. A simple blinky style project,
- * and a more comprehensive test and demo application. The
- * mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting (defined in this file) is used to
- * select between the two. The simply blinky demo is implemented and described
- * in main_blinky.c. The more comprehensive test and demo application is
- * implemented and described in main_full.c.
- *
- * This file implements the code that is not demo specific, including the
- * hardware setup and FreeRTOS hook functions.
- *
- * !!! IMPORTANT NOTE !!!
- * The GCC libraries that ship with the Xilinx SDK make use of the floating
- * point registers. To avoid this causing corruption it is necessary to avoid
- * their use. For this reason main.c contains very basic C implementations of
- * the standard C library functions memset(), memcpy() and memcmp(), which are
- * are used by FreeRTOS itself. Defining these functions in the project
- * prevents the linker pulling them in from the library. Any other standard C
- * library functions that are used by the application must likewise be defined
- * in C.
