* !!! 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
+ * their use unless a task has been given a floating point context. See\r
+ * http://www.freertos.org/Using-FreeRTOS-on-Cortex-A-Embedded-Processors.html\r
+ * for information on how to give a task a floating point context, and how to\r
+ * handle floating point operations in interrupts. As this demo does not give\r
+ * all tasks a floating point context main.c contains very basic C\r
+ * implementations of the standard C library functions memset(), memcpy() and\r
+ * memcmp(), which are are used by FreeRTOS itself. Defining these functions in\r
+ * the project prevents the linker pulling them in from the library. Any other\r
+ * standard C library functions that are used by the application must likewise\r
+ * be defined in C.\r

-#
-# GNU General Public License Exception
-#
-# Any FreeRTOS source code, whether modified or in its original release form,

-#
-# EXCEPTION TEXT:
-#
-# Clause 1
-#
-# Linking FreeRTOS statically or dynamically with other modules is making a
-# combined work based on FreeRTOS. Thus, the terms and conditions of the
-# GNU General Public License cover the whole combination.
-#
-# As a special exception, the copyright holder of FreeRTOS gives you permission
-# to link FreeRTOS with independent modules that communicate with FreeRTOS
-# solely through the FreeRTOS API interface, regardless of the license terms
-# of these independent modules, and to copy and distribute the resulting
-# combined work under terms of your choice, provided that
-#
-# Every copy of the combined work is accompanied by a written statement that
-# details to the recipient the version of FreeRTOS used and an offer by
-# yourself to provide the FreeRTOS source code (including any modifications
-# you may have made) should the recipient request it.
-# The combined work is not itself an RTOS, scheduler, kernel or related product.
-# The independent modules add significant and primary functionality to FreeRTOS
-# and do not merely extend the existing functionality already present
-# in FreeRTOS.
-#
-# Clause 2
-#
-# FreeRTOS may not be used for any competitive or comparative purpose,
-# including the publication of any form of run time or compile time metric,
-# without the express permission of Real Time Engineers Ltd. (this is the norm
-# within the industry and is intended to ensure information accuracy).
