28 * FreeRTOS+TCP can be used under two different free open source licenses. The
\r
29 * license that applies is dependent on the processor on which FreeRTOS+TCP is
\r
30 * executed, as follows:
\r
32 * If FreeRTOS+TCP is executed on one of the processors listed under the Special
\r
33 * License Arrangements heading of the FreeRTOS+TCP license information web
\r
34 * page, then it can be used under the terms of the FreeRTOS Open Source
\r
35 * License. If FreeRTOS+TCP is used on any other processor, then it can be used
\r
36 * under the terms of the GNU General Public License V2. Links to the relevant
