关于TMS320C6678 SRIO 中断的问题

Other Parts Discussed in Thread: TMS320C6678

各位专家:

    论坛中提供了一个TMS320C6678 SRIO的测试程序。http://www.deyisupport.com/question_answer/f/53/t/4773.aspx 

   我在开发板上测试了SRIO_DIGITAL_LOOPBACK 模式下的DerectIO 读写,Messege和 Doorbell。程序中使能了Messege和 Doorbell的中断,但是程序运行时这两个中断始终没有被触发执行,请问需要设置或是修改什么地方么?

  谢谢!
