关于CC3200 在TI-OS下外设优先级、优先级寄存器组的设置

Other Parts Discussed in Thread: CC3200

Hi,最近在用CC3200做一款产品

软件是基于getting_started_with_wlan_station例程修改的

1、发现TI-OS本身仅提供了设置优先级的函数

OsiReturnVal_e osi_InterruptRegister(int iIntrNum, P_OSI_INTR_ENTRY pEntry, unsigned char ucPriority),

并未有提供设置优先级寄存器组的相关函数,

想实现外设中断嵌套如何设置?例如我开启了定时器中断和串口中断,串口中断可以抢占定时器中断,如何设置?

默认的优先级寄存器组是???

2、CC3200是双核SOC芯片  M4核运行用户代码,M3核运行协议栈 ,我了解两个核之间的通讯接口是SPI,在TI-OS中,TI是如何管理这个接口的优先级,是最高的么?

盼复,

谢谢!
