srio lcb

读取Reg6的LCB与读取的影子寄存器LSU_STAT_REG的LCB不相等，这是什么原因？

Reg6的LCB = 0；

影子寄存器LSU_STAT_REG的LCB = 1；

导致程序死在KeyStone_SRIO_wait_LSU_completion（）函数。

    LCB 用来区分两次不同的传输，显然你上次的传输未完成，应该检查一下SRIO的状态及错误寄存器看发生了何种错误

    调用print_SRIO_status_error（），信息如下：

    Input port 0 next expected ackID value: 0x0
    Output port 0 unacknowledged ackID: 0x0
    Output port 0 next transmitted ackID value: 0x1
    The output port 0 is in the output error-stopped state.
    The input port 0 is in the input error-stopped state.
    Port 0 OK condition. The input and output ports are initialized, and the port is exchanging error-free control symbols with the attached device.

    好像没有什么错误呀？
