dma flag sigal不变

大家好
数据流
PC-＆GT；USOCKET---＆GT & GT；DMA-＆GT & GT；PSoCuPETS --GPIF
FLAGA致力于TreRe0，Flagb致力于THEADR1，Flagc致力于TaDa2等。
部分代码FX3Y-McAcLeCuxEP2（…）无效的FX3Y-McAcLaCudieEP2（CYU3PDMAChans*CHAD，CYU3PDMACKByType T类型，CYU3PDMACIMPUTPUT**输入）{//Unt1616t索引；CyU3PDMABUFFEFRYT BUFFP，InBufFP，OutBuffp；Cyu3PrEntStutsUst状态＝CyuU3Py成功；IF（type＝CyuU3PyDMABCBOPRODYEL事件）{//用于调试状态= CYU3PDMACHANNEL GETFULL（CHARTURE，ANP；NBUFFP P，CYU3PY NoYORE等待）；状态= CYU3PDMACHANNEL COMPASTROM缓冲器（CHRADHER，输入-GT；BuffelyP.Calt，0）；}我使用CYU3PDMACHANEL GETBUFER（）API来查找数据形式的PC。CyuY3PDMACHANNEL COMPAREL BUFER（）函数是返回成功的。我的问题是为什么FLAC信号没有改变感谢？

  Hi everyone
    data flow
    pc->>usocket----->>>dma---->>>psockets----GPIF----
     FLAGA is dedicated to thread0 ,Flagb is dedicated to thread1,Flagc is dedicated to theread2,and so on.
    part code
fx3_DmaCallback_EP2 (....)
void fx3_DmaCallback_EP2 (
CyU3PDmaChannel *chHandle,
CyU3PDmaCbType_t type,
CyU3PDmaCBInput_t *input)
{
//uint16_t index;
CyU3PDmaBuffer_t buf_p,inBuf_p,outBuf_p;
CyU3PReturnStatus_t status = CY_U3P_SUCCESS;
if (type == CY_U3P_DMA_CB_PROD_EVENT)
{
// for debug
status = CyU3PDmaChannelGetBuffer(chHandle,&inBuf_p,CYU3P_NO_WAIT);
status = CyU3PDmaChannelCommitBuffer (chHandle, input->buffer_p.count, 0);
...............................
}
I used CyU3PDmaChannelGetBuffer() API to find data form pc..the CyU3PDmaChannelCommitBuffer () function is return success. my question is why was not the FLAGC signal change
thanks
