CPU : Davinci DM8168
DVRRDK: 3.0
Hi everyone
In my usecase, DMA copy data from PCIE and receive the data of the network by the live555,DMA copy the data to display and occur the split screen int the window after the DM8168 run for a while.
Below is our code.
DMA copy data the init code:
status = Vsys_allocBuf(FRAMEBUF_HEAP_SR_ID,thrObj->bufSize,1024,&thrObj->bufInfo[i]);
if (ERROR_NONE == status)
{
bufList.numFrames++;
pFrame = &bufList.frames[i];
pFrame->channelNum = 0;
pFrame->fid = 0;
pFrame->frameHeight = thrObj->frameHight;
pFrame->frameWidth = thrObj->frameWidth;
pFrame->framePitch[0] = (pFrame->frameWidth)*2;
pFrame->phyAddr[0][0] = thrObj->bufInfo[i].physAddr;
pFrame->addr[0][0] = thrObj->bufInfo[i].virtAddr;
}
status = IpcFramesOutLink_putFullVideoFrames(SYSTEM_HOST_LINK_ID_IPC_FRAMES_OUT_0,&bufList);
OSA_assert(0 == status);
int dmainitret = OSA_dmaInit();
OSA_dmaOpen(&thrObj->dmaHndl, OSA_DMA_MODE_NORMAL, 1);
thrObj->copy2D.copyWidth = (thrObj->frameWidth) * 2;
thrObj->copy2D.copyHeight = thrObj->frameHight;
thrObj->copy2D.srcOffsetH = (thrObj->frameWidth) * 2;
thrObj->copy2D.dstOffsetH = (thrObj->frameWidth) * 2;
thrObj->copy2D.skipH = 0;
DMA copy data the run code:
status = IpcFramesOutLink_getEmptyVideoFrames(SYSTEM_HOST_LINK_ID_IPC_FRAMES_OUT_0,&bufList);
OSA_assert(0 == status);
if (bufList.numFrames)
{
i = 0;
while (i < bufList.numFrames)
{
unsigned long ppIndex = ioctl(thrObj->devfd, 4, 0);
pFrame = &bufList.frames[i];
pFrame->channelNum = 0;
pFrame->fid = 0;
pFrame->frameHeight = thrObj->frameHight;
pFrame->frameWidth = thrObj->frameWidth;
pFrame->framePitch[0] = (pFrame->frameWidth)*2;
thrObj->copy2D.srcPhysAddr = (unsigned long)ppMemPhyAddr[ppIndex];
thrObj->copy2D.dstPhysAddr = (unsigned long)pFrame->phyAddr[0][0];
OSA_dmaCopy2D(&thrObj->dmaHndl, &thrObj->copy2D, 1);
i++;
}
status = IpcFramesOutLink_putFullVideoFrames(SYSTEM_HOST_LINK_ID_IPC_FRAMES_OUT_0,&bufList);
ipcBit run code
status = OSA_queGet(&(ipc_ctrl.queEmptyOut), (Int32 *) (&pEmptyBuf),OSA_TIMEOUT_FOREVER);
//to append treatment for queget failure...
pEmptyBuf->channelNum = pStream->decChannel;
pEmptyBuf->codingType = 0;
pEmptyBuf->timeStamp = OSA_getCurTimeInMsec();
pEmptyBuf->fillLength = 0;
status = getOneFrame(pStream, pEmptyBuf->addr,&(pEmptyBuf->fillLength));
status = OSA_quePut(&(ipc_ctrl.queFullOut), (Int32) pEmptyBuf,OSA_TIMEOUT_FOREVER);

What cause this issue, and how can I fix it?
Appreciate it for your response!
