6748开发板网络例程调试提示错误

[tr]我用6748开发板调试网络通信例程（基于stareware和sys/bios下）遇见以下问题，请有经验的大侠指点一下：
1、基于stareware的例程ENET_HTTPD调试
   编译可以通过，但是在debug运行时提示：
  Can't find a source file at "D:/StarterWare_Gitorious_C6748/StarterWare_01_20_04_01/drivers/psc.c"
Locate the file or edit the source lookup path to include its location.
我把psc.c文件导入之后，没有任何现象（串口也没有提示）

2、基于sys/bios的例程调试（以tcp_client为例）
编译可以通过，在debug运行时提示：
TMS320C64X+_0: Warning: CPUEnabled)Interrupt No. 14 dropped, an earlier interrupt is pending to be taken  
TMS320C64X+_0: Warning: CPUEnabled)Interrupt No. 14 dropped, an earlier interrupt is pending to be taken  
我查看了一下，程序走到csl_emac.c停在while (ECTL_REGS->SOFTRESET != 0x00000000);  /* Wait until reset has occured */
按照意思是，给一个中断信号才能执行下去，问题是我如何触发一个中断。
并且这时有提示：
Can't find a source file at "/db/vtree/library/trees/nsp/nsp-b09x/src/ti/drv/omapl138/ethdriver.c"
Locate the file or edit the source lookup path to include its location.
Can't find a source file at "/db/vtree/library/trees/nsp/nsp-b09x/src/ti/drv/omapl138/nimu_eth.c"
Locate the file or edit the source lookup path to include its location.
Can't find a source file at "/db/vendors/ti/c6x/7.2.0/Linux/include/string.h"
Locate the file or edit the source lookup path to include its location.
我把这几个文件导入工程之后，仍然提示：
TMS320C64X+_0: Warning: CPUEnabled)Interrupt No. 14 dropped, an earlier interrupt is pending to be taken  
TMS320C64X+_0: Warning: CPUEnabled)Interrupt No. 14 dropped, an earlier interrupt is pending to be taken  
请问这是什么原因？

3、另外请问一下stareware 是基于非操作系统的，但是我能在sys/bios下应用stareware 吗？
