- * This project provides three demo applications. A simple blinky style\r
- * project, a more comprehensive test and demo application, and an lwIP example.\r
- * The mainSELECTED_APPLICATION setting (defined in this file) is used to\r
- * select between the three. The simply blinky demo is implemented and\r
- * described in main_blinky.c. The more comprehensive test and demo application\r
- * is implemented and described in main_full.c. The lwIP example is implemented\r
- * and described in main_lwIP.c.\r
- *\r
- * This file implements the code that is not demo specific, including the\r
- * hardware setup and FreeRTOS hook functions.\r
- *\r
- * !!! IMPORTANT NOTE !!!\r
- * The GCC libraries that ship with the Xilinx SDK make use of the floating\r
- * point registers. To avoid this causing corruption it is necessary to avoid\r
- * their use. For this reason main.c contains very basic C implementations of\r
- * the standard C library functions memset(), memcpy() and memcmp(), which are\r
- * are used by FreeRTOS itself. Defining these functions in the project\r
- * prevents the linker pulling them in from the library. Any other standard C\r
- * library functions that are used by the application must likewise be defined\r
- * in C.\r
- *\r
- * ENSURE TO READ THE DOCUMENTATION PAGE FOR THIS PORT AND DEMO APPLICATION ON\r
- * THE http://www.FreeRTOS.org WEB SITE FOR FULL INFORMATION ON USING THIS DEMO\r
