Not able to initialize InicheStack

Honored Contributor II



I am using Stratix IV GX Development kit with Quartus II 15.0. I configured the fpga with an example design -- niosii-ethernet-standard-4sgx230. 

I want to run Simple Socket Server example. From one of the pdfs I read that uC/OS II should have at max 4 tasks or less to use NicheStack TCP/IP Stack. Everything seems to fine until it tries to initialize the niche stack by calling netmain().  


I get the following displayed on NIOS II console (This is after I see the OSTaskCtr to be 5, there are also some OS internal tasks):  

prepped 0 interfaces, initializing... 

inet setup error: unable to find any working interfaces 

panic: IP 

dtrap - needs breakpoint 



Can someone guide me here.. as to what should I do for this to not happen?
