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

Honored Contributor II



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) 


"Failed to create SSSLEDLightshowSem.\n"); 



since then i have the info below coming out of the jtag uart.
