1642boost 与DCA1000 EMV 数据接口问题

Other Parts Discussed in Thread: DCA1000EVM, IWR1642

    你好，IWR1642 参考资料中 说设备通过LVDS接口传输ADC数据 给DCA1000EVM；

    但同时在TI原理图参考设计中，也设计了“trace  data 0~data 15 ”，如下图），这组数据线也连接到DCA1000 EMV，请问这传输的是什么数据呢？

       和LVDS传输的ADC数据有什么关系？

    你好，
    预留的是DMM接口，可将PC机的数据，通过此接口灌回到1642内部RAM里进行调试。
    可参考数据手册中如下描述，谢谢。

    Data Modification Module (DMM)
    A Data Modification Module (DMM) gives the ability to write external data into the device memory.
    The DMM has the following features:
    • Acts as a bus master, thus enabling direct writes to the 4GB address space without CPU intervention
    • Writes to memory locations specified in the received packet (leverages packets defined by trace mode
    of the RAM trace port [RTP] module)
    • Writes received data to consecutive addresses, which are specified by the DMM (leverages packets
    defined by direct data mode of RTP module)
    • Configurable port width (1, 2, 4, 8, 16 pins)
    • Up to 65 Mbit/s pin data rate
