同步从属FIFO双EP问题

嗨，我写信给论坛，因为我真的混淆了GPIF同步FIFO接口的关联线程套接字。我使用从同步FIFO例子（把DMA通道在汽车上）作为起点，但我现在无法继续。
我的需要是：
1）EP1使用自动DMA作为输入和输出数据，从数据端口传送和读取数据。
2）然后，我需要第二个端点EP2也工作进出。
EP1通常用于传输大数据块，并且使用异步数据传输（来自CyAPI点；而不是异步GIPIF）访问。这是完美的，我能够发送和接收数据到GPIF接口。
在这种情况下，你的选择是：
*定义CyfxxEpPixPix0x01/*EP 1 out *//
*定义*0x81/*EP 1中的CyfxfxEppAuthor
定义了CyfxxPultReSuxBuSocket Cyu3PyuBiSockyPodLy1/1/USB USB套接字1是生产者*/
*定义CyfxfxCuffiSuxBuSocket CyuU3PyuBiSocktisCux1/*USB USB套接字1是消费*/
定义了CyfxxPuxelyPpPotoSocket CyuU3pPiBiSockt0/*P-端口套接字0是生产者*/
*定义CyfxfxPuxelpPotoSocket CyuU3pPiBiSocky3/*P-端口套接字3是消费者*/
在参考设计中，使用2个DMA通道设置：
…
DMACFG.PRODSCKID = CyfxFxPultReuleSubSoCult；
DCMAFG.COXSCHAVE＝CyfxFuxEuffer-PpPosiSosik；
…
ApIdReStase= CYU3PDMACHANNEL CREATION（＆GLCHANDACLE LIFOUTOP，CYUU3PYDMAX型AUTO，和DMACFG）；
…
对于USB 2 FX3通道和
…
DMACGF.PRODSCKID = CyfxxPuxelyPpPosiSosik；
DCMAFG.CascSKID= CyfxfxCuffier-U***SoCult；
…
ApItReStase= CYU3PDMACHANNEL CREATION（＆GLCHANDACLE LIFOPPOTH，CYUU3PYDMAX型AUTO，和DMACFG）；
对于FX3 2 USB DMA通道。
第一个问题：如何将USB插槽号映射到端点号。看看你的例子，我应该使用CyuU3PyuuBiSokpO-Pyd1和CyuU3PyuBiSoCuxCux1，EP 1和CyuU3PyuBiSokpKyPrd2和CyuU3PuuBiSoCuxCuxE2为EP2，……这是正确的吗？
为了建立第二组DMA通道，我修改了上面的定义如下
*定义CyfxxEpPixPix0x01/*EP 1 out *//
*定义*0x81/*EP 1中的CyfxfxEppAuthor
*定义CyfxfxEppGuieldSerix0x02/*EP 2 out *//
*定义*0x82/*EP 1中的CyfxfxEpp-Cuffiel**
定义了CyfxxPultReSuxBuSocket Cyu3PyuBiSockyPodLy1/1/USB USB套接字1是生产者*/
*定义CyfxfxCuffiSuxBuSocket CyuU3PyuBiSocktIsCux1/*USB USB套接字1是消费*/
定义了CyfxxPuxuleSubBocket，新的CyuU3PuuBiSocktPoDy2/2/USB套接字2是生产者*/
*定义CyfxfxEuthuleSubSockType新的CuU3PyuBiSockSocux2.2/*USB套接字2是消费*/
定义了CyfxxPuxelyPpPotoSocket CyuU3pPiBiSockt0/*P-端口套接字0是生产者*/
*定义CyfxfxPuxelpPotoSocket CyuU3pPiBiSocky3/*P-端口套接字3是消费者*/
定义了CyfxxPultRealPtPosixSockTo.CyuU3pPiBiSockt1／*P-端口套接字1是生产者*/
*定义CyfxfxCuffelpPotoSockToeCyuU3pPiBiSockt2/2/*P-端口套接字2是消费者*/
然后我复制你的代码来设置2个新的DMA通道：
…
DMACFG.PRODSCKID＝CyfxfxPuthuleSubbSokKeTeLeNe；
DCMAFG.CascSKID= CyfxfxEuthelypPtPosiSokKeNeNeX；
…
ApIdReStase= CYU3PDMACHANNEL CREATED（＆GLCHANHANDSLL FIFOUTPOLY NULL，CYU-U3PYDMAX Type AUTO，和DMACFGGHONE）；
…
对于USB 2 FX3通道和
…
DMACGF.PRODSCKID＝CyfxfxPuthelePpPotoSoCKeTyNew；
DCMAFG.CascSKID= CyfxfxEuthuleSubBoSoKeLeNeX；
…
ApIdReStase= CYU3PDMACHANNEL CREATED（＆GLCHANDACLLL FIFOPPUTHONE，CYUU3PYDMAX Type M AUTO，和DMACFGGHONE）；
第一个问题：根据我所需要的描述，我的Socket映射是正确的吗？
如果是的话，EP1在内外都是完美的，但是EP2根本就没有。
我错过什么了吗？有什么建议吗？
谢谢你，乔尔

     以下为原文
  Hi, I’m writing to the forum since I’m really confused about the association Thread-Socket for the GPIF sync FIFO interface. I used the Slave sync FIFO example (putting DMA channels on AUTO) as a starting point but I’m now unable to go ahead.
    My needs are:
    1)       EP1 working as IN and  OUT, transferring and reading data to and from the PPort using automatic DMA.
    2)       I then need a second endpoint EP2 working too  as IN and OUT
    EP1 is typically used to transfer big chunk of data and is accessed using async  data transfer (from the CyAPI point of view; not async GIPIF!) . This works perfectly and I’m able to send and receive data to/from the GPIF interface.
    In this case your selection was:
     
    #define CY_FX_EP_PRODUCER               0x01    /* EP 1 OUT */
    #define CY_FX_EP_CONSUMER               0x81    /* EP 1 IN */
     
    #define CY_FX_PRODUCER_USB_SOCKET    CY_U3P_UIB_SOCKET_PROD_1    /* USB Socket 1 is producer */
    #define CY_FX_CONSUMER_USB_SOCKET    CY_U3P_UIB_SOCKET_CONS_1    /* USB Socket 1 is consumer */
     
    #define CY_FX_PRODUCER_PPORT_SOCKET    CY_U3P_PIB_SOCKET_0    /* P-port Socket 0 is producer */
    #define CY_FX_CONSUMER_PPORT_SOCKET    CY_U3P_PIB_SOCKET_3    /* P-port Socket 3 is consumer */
     
    In your reference design you the set up the 2 DMA channels using :
     
    …
        dmaCfg.prodSckId = CY_FX_PRODUCER_USB_SOCKET;
        dmaCfg.consSckId = CY_FX_CONSUMER_PPORT_SOCKET;
    …
        apiRetStatus = CyU3PDmaChannelCreate (&glChHandleSlFifoUtoP, CY_U3P_DMA_TYPE_ AUTO, &dmaCfg);
    ..
     
    For the USB 2 FX3 channel and
    …
        dmaCfg.prodSckId = CY_FX_PRODUCER_PPORT_SOCKET;
        dmaCfg.consSckId = CY_FX_CONSUMER_USB_SOCKET;
    …
       apiRetStatus = CyU3PDmaChannelCreate (&glChHandleSlFifoPtoU, CY_U3P_DMA_TYPE_ AUTO, &dmaCfg);
     
    For the FX3 2 USB  DMA channel.
     
    First question: how maps the USB socket number to the Endpoint number. Looking at your example I should use CY_U3P_UIB_SOCKET_PROD_1    and CY_U3P_UIB_SOCKET_CONS_1    for EP 1 and  CY_U3P_UIB_SOCKET_PROD_2    and CY_U3P_UIB_SOCKET_CONS_2 for EP2,…  is this correct ?
    In order to set up a second    group of DMA channels I modified the above definition as following
     
    #define CY_FX_EP_PRODUCER               0x01    /* EP 1 OUT */
    #define CY_FX_EP_CONSUMER               0x81    /* EP 1 IN */
    #define CY_FX_EP_PRODUCER_NEW      0x02    /* EP 2 OUT */
    #define CY_FX_EP_CONSUMER_NEW     0x82    /* EP 1 IN */
     
    #define CY_FX_PRODUCER_USB_SOCKET    CY_U3P_UIB_SOCKET_PROD_1    /* USB Socket 1 is producer */
    #define CY_FX_CONSUMER_USB_SOCKET    CY_U3P_UIB_SOCKET_CONS_1    /* USB Socket 1 is consumer */
    #define CY_FX_PRODUCER_USB_SOCKET_NEW    CY_U3P_UIB_SOCKET_PROD_2    /* USB Socket 2 is producer */
    #define CY_FX_CONSUMER_USB_SOCKET_NEW   CY_U3P_UIB_SOCKET_CONS_2    /* USB Socket 2 is consumer */
     
    #define CY_FX_PRODUCER_PPORT_SOCKET    CY_U3P_PIB_SOCKET_0    /* P-port Socket 0 is producer */
    #define CY_FX_CONSUMER_PPORT_SOCKET    CY_U3P_PIB_SOCKET_3    /* P-port Socket 3 is consumer */
    #define CY_FX_PRODUCER_PPORT_SOCKET_NEW    CY_U3P_PIB_SOCKET_1    /* P-port Socket 1 is producer */
    #define CY_FX_CONSUMER_PPORT_SOCKET_NEW    CY_U3P_PIB_SOCKET_2    /* P-port Socket 2 is consumer */
     
    I then copied your code to set up the 2 new DMA channels:
     
    …
        dmaCfg.prodSckId = CY_FX_PRODUCER_USB_SOCKET_NEW;
        dmaCfg.consSckId = CY_FX_CONSUMER_PPORT_SOCKET_NEW;
    …
        apiRetStatus = CyU3PDmaChannelCreate (&glChHandleSlFifoUtoP_new, CY_U3P_DMA_TYPE_ AUTO, &dmaCfg_new);
    ..
     
    For the USB 2 FX3 channel and
    …
        dmaCfg.prodSckId = CY_FX_PRODUCER_PPORT_SOCKET_NEW;
        dmaCfg.consSckId = CY_FX_CONSUMER_USB_SOCKET_NEW;
    …
       apiRetStatus = CyU3PDmaChannelCreate (&glChHandleSlFifoPtoU_new, CY_U3P_DMA_TYPE_M AUTO, &dmaCfg_new);
     
     
    First question: is my socket mapping correct according to the description of what I need ?
    If yes, EP1 works perfectly both IN and OUT, but EP2 simply doesn’t.  In none of the directions…
     
    Do I’m missing something?  Any suggestion ?
     
    Thanks in advance, Joel
