* FreeRTOS+FAT FS V1.0.0 (C) 2013 HCC Embedded
|
|
*
|
|
* The FreeRTOS+FAT SL license terms are different to the FreeRTOS license
|
|
* terms.
|
|
*
|
|
* FreeRTOS+FAT SL uses a dual license model that allows the software to be used
|
|
* under a standard GPL open source license, or a commercial license. The
|
|
* standard GPL license (unlike the modified GPL license under which FreeRTOS
|
|
* itself is distributed) requires that all software statically linked with
|
|
* FreeRTOS+FAT SL is also distributed under the same GPL V2 license terms.
|
|
* Details of both license options follow:
|
|
*
|
|
* - Open source licensing -
|
|
* FreeRTOS+FAT SL is a free download and may be used, modified, evaluated and
|
|
* distributed without charge provided the user adheres to version two of the
|
|
* GNU General Public License (GPL) and does not remove the copyright notice or
|
|
* this text. The GPL V2 text is available on the gnu.org web site, and on the
|
|
* following URL: http://www.FreeRTOS.org/gpl-2.0.txt.
|
|
*
|
|
* - Commercial licensing -
|
|
* Businesses and individuals who for commercial or other reasons cannot comply
|
|
* with the terms of the GPL V2 license must obtain a commercial license before
|
|
* incorporating FreeRTOS+FAT SL into proprietary software for distribution in
|
|
* any form. Commercial licenses can be purchased from
|
|
* http://shop.freertos.org/fat_sl and do not require any source files to be
|
|
* changed.
|
|
*
|
|
* FreeRTOS+FAT SL is distributed in the hope that it will be useful. You
|
|
* cannot use FreeRTOS+FAT SL unless you agree that you use the software 'as
|
|
* is'. FreeRTOS+FAT SL is provided WITHOUT ANY WARRANTY; without even the
|
|
* implied warranties of NON-INFRINGEMENT, MERCHANTABILITY or FITNESS FOR A
|
|
* PARTICULAR PURPOSE. Real Time Engineers Ltd. and HCC Embedded disclaims all
|
|
* conditions and terms, be they implied, expressed, or statutory.
