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

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.
