Simple Socket Server example ---> Failed to create semaphore

[Altera_Forum]

Hi, 

 I am using the Simple Socket Server example. My application was working OK with SUPERLOOP but now I need multi threads so I need to make my application works with the OS so I started with the example. I tried with my first project with only one UART and it is working. The program is not able to create the semaphore because the memory looks not empty I think :   SSSLEDLightshowSem = OSSemCreate(1);    if (!SSSLEDLightshowSem)  {  alt_uCOSIIErrorHandler(EXPANDED_DIAGNOSIS_CODE,   "Failed to create SSSLEDLightshowSem.\n");  }   since then i have the info below coming out of the jtag uart.  InterNiche Portable TCP/IP, v3.1   Copyright 1996-2008 by InterNiche Technologies.
