CC3220R BUG???? 调用Power_disablePolicy后内部DCDC VDD_PA无法启动



CC3220R显示调用Power_enablePolicy,使能lpds,芯片能正常进入低功耗。sleep(5)休眠5秒后芯片唤醒,调用Power_disablePolicy,禁止低功耗,之后无论是直接调用sleep还是等待信号量使程序阻塞,芯片就是死机。示波器显示DCDC(VDD_PA) 开关频率再也无法启动

程序如下:

while(1)
{
Power_enablePolicy();
sleep(5);
Report("aaa\r\n");
Power_disablePolicy();
sleep(5);
Report("bbb\r\n");
}

测试的两个板子如下:
