是否可以在GPIF套接字和主机模式端点套接字之间创建dma通道？

我在主机模式下使用FX3 DVK。
当我在GPARIN中创建GPIF（P端口）套接字和CPU之间的DMA通道时，
（GPIF插座是生产者，CPU插座是消费者）
回调例程被调用。
但是，
当我在GPIF（P端口）套接字和主机模式端点（U-PART）之间创建DMA通道时，
（GPIF插座是生产者，端点插座是消费者）
不调用回调例程。

  I use FX3 DVK on host mode.
    When i create a dma channel between GPIF(P port) socket and CPU in MANUAL-IN,
    (GPIF socket is Producer, CPU socket is Consumer)
    a Callback routine is called.
     
    but,
    When i create a dma channel between GPIF(P port) socket and Host mode Endpoint(U-port) in MANUAL,
    (GPIF socket is Producer, Endpoint socket is Consumer)
    a Callback routine is not called.
