Is somebody here? Maybe Nobody.But I still ask some question.please help me

I am developing a communication system base on NS7520.Now i am learning the develop board. I am trying to run the example naserial.I have rebulid the bsp according the readme.txt. By the way,how can I read the result of the program. I have designed a new program based on the naserrial.The program is very simple,I just let the /com/1 to send some characters.But I failed.I have zip the file as attachment to you.Can someone diagnose it for me thanks. And i have modified the bspconfg.h too.

Did you try to run original naserial application ? did it work ?
