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?
