重新发布，再次…GPIFII是主模式，我尝试创建“CyuU3PyDMAX Type MalaLoin”的DMA通道（CH1）和“CyuU3PyDMAX Type MaMalAlxOUT”通道（CH0）。但是，我只能创建CH0或CH1。当我创建“CyuU3PyDMAYType MualAlxOUT”和“in in”通道时，我编写如下代码。为了启动“GPIF状态机”，我使用“CyuU3PiPIbSoCKETY0”创建了“PRODSCKID”，然后称为“CYU3PDMACHANNETSUBPRECVBUSER（）”。这个过程很好。我得到了预期的功能。然而，当我使用“CyuU3PiPixSoCKET1”而不是“CyuU3PiBixSoCKo.0”时，它并没有运行。我想在DMA通道（CH1）和输出DMA通道（CH0）中创建。因此，对于CH0，我用Cyu3PiPiBixSokKe1作为C1和“CyuU3PiPixSoxKy0”。但是，在使用“CyuU3PiPIbSoCKETY1”时，它不运行。为什么？DMACGF.CUTE＝512；DMACFG.PRODFADSCOUNT＝0；DMACFG.DMAMODE＝CyuU3PyDMAYMDEDEMY字节；DMACFG.PRODHOPETHER＝0；DMACGF.CONSEADADER＝0；DMACFGG通知＝0；DMACFG.CB＝NULL；//CH1（GPIF2到CPU）//DMACFF.PRODSCKID＝CyuU3PYPIB SOCKET0O；//OK DMACFF.PRODSCK；PiPIbSoCKETY1；/NGDMAFG.CasyU3PyCulk SokKy-CONS；状态= CYU3PDMACHANILIGEN（和GLCHHANDRIGPIFIGIN，CYUU3PYDMAYTYPE，MUMALALIN，和DMACFG）；//CH0（CPU到GPIF2）DMACFG.PRODSCKID = CyuU3PyPcPoCKEL PROD；DMACFG.CascSKID＝CyuU3PYPIB SOCKET0；状态＝CYU3PDMACHA ID＝CyuU3NNELCREATE（＆GLCHHANDRACEPIFRIGUT，CYU-U3PYDMAYTYPE MUROALLYOUT，和DMACFG）；

          Re-POST, again..... GPIFII is master mode, I try to create "CY_U3P_DMA_TYPE_MANUAL_IN" DMA channel(CH1) and "CY_U3P_DMA_TYPE_MANUAL_OUT" channel(CH0). However, I can only create CH0 or CH1. When I create "CY_U3P_DMA_TYPE_MANUAL_OUT" & " _IN" channel, I write the code as below. To start the "GPIF state machine", I created "prodSckId" by using "CY_U3P_PIB_SOCKET_0" then called "CyU3PDmaChannelSetupRecvBuffer()". This procedure is fine. I got my expected function. However, it didn't run when I used "CY_U3P_PIB_SOCKET_1" instead of "CY_U3P_PIB_SOCKET_0". I want to cretae IN DMA channel(CH1) and OUT DMA channel(CH0). So, I use "CY_U3P_PIB_SOCKET_1" for CH1 and "CY_U3P_PIB_SOCKET_0" for CH0. However, it doesn't run in case of using "CY_U3P_PIB_SOCKET_1". Why? dmaCfg.size = 512; dmaCfg.count = 0; dmaCfg.prodAvailCount = 0; dmaCfg.dmaMode = CY_U3P_DMA_MODE_BYTE; dmaCfg.prodHeader = 0; dmaCfg.prodFooter = 0; dmaCfg.consHeader = 0; dmaCfg.notification = 0; dmaCfg.cb = NULL; // CH1(GPIF2 to CPU) // dmaCfg.prodSckId = CY_U3P_PIB_SOCKET_0; // OK dmaCfg.prodSckId = CY_U3P_PIB_SOCKET_1; // NG dmaCfg.consSckId = CY_U3P_CPU_SOCKET_CONS; status = CyU3PDmaChannelCreate( &glChHandleGPIFRegIn, CY_U3P_DMA_TYPE_MANUAL_IN, &dmaCfg ); // CH0(CPU to GPIF2) dmaCfg.prodSckId = CY_U3P_CPU_SOCKET_PROD; dmaCfg.consSckId = CY_U3P_PIB_SOCKET_0; status = CyU3PDmaChannelCreate( &glChHandleGPIFRegOut, CY_U3P_DMA_TYPE_MANUAL_OUT, &dmaCfg );

如果可能的话，请您附上您的项目源代码。
如果不是，请粘贴您正在创建这两个通道的代码部分。
谢谢，
西克里希纳。

  Sumitsu,
    Could you please attach your project source code, if possible.
    If not, please paste the part of code where you are creating both of these channels.
    Thanks,
