hi guys,

i need to write a LwIP Ethernet application on ADSP-BF561 EZ-KIT Lite Evaluation System Rev1.3 and Blackfin USB-LAN EZ-Extender Rev1.2.  IDDE is VisualDSP 5.1.

When i run the example in <visualdsp_instal_path>\Blackfin\Examples\USB-LAN EZ-EXTENDER\LAN\, the everything is all right. The information "Link established" and "IP Address :" can display in the console window.

After that,  i use New -> Project -> choose LwIP Ethernet application and  Next -> choose processor types ADSP-BF561, then leave other things as default and press Finish button .And then build and run this project,i can only see "Link established" but no "IP Address".

Then i found that this program can't run out of the function "start_stack()" in source file lwip_sysboot_threadtype.c, line 219.


if(system_init() == -1)


     printf("Failed to initialize system\n");







     printf("IP ADDRESS: %s\n",ip);



so what is going wrong?

thank you very much !
