FPGA接DM8147 VIP0的portA 16bit discreate模式capture_link无法接收到数据

DM8147 VIP0的portA接FPGA无法接收到数据。

我们使用FPGA接4个AP0101，把四个数据通过FPGA合成一个之后通过VIP0的portA传给DM8147的HDVPSS，我们将ISS的初始化代码注释了，但是现在capturelink一直采集不到数据，请大神帮忙分析一下原因。

开发包IPNC_RDK3.5

现在我们用FPGA输出YUV数据，使用16根数据线，输入格式为SYSTEM_DF_YUV422P    SYSTEM_STD_1080P_30 使用CLK HSYNC 

以下是对程序的修改：

【ipnc_rdk中修改的内容】

文件captureLink_drv.c

Int32 CaptureLink_drvCreateInst(CaptureLink_Obj * pObj, UInt16 instId)
{
。。。
pVipCreateArgs->videoCaptureMode = VPS_CAPT_VIDEO_CAPTURE_MODE_SINGLE_CH_NON_MUX_DISCRETE_SYNC_HSYNC_VSYNC;
pVipCreateArgs->videoIfMode = VPS_CAPT_VIDEO_IF_MODE_16BIT;
。。。
}

并将system_m3vpss.c文件中Int32 System_init()中有关iss的代码都注释掉

【HDVPSS中修改的内容】

文件：vpsdrv_captureVip.c中修改的内容（函数Vps_captVipParserConfigSetup中）

vipPortConfig->disConfig.fidDetectMode = VPS_VIP_FID_DETECT_MODE_VSYNC;//zzh
vipPortConfig->disConfig.actvidPol = VPS_VIP_POLARITY_HIGH;
vipPortConfig->disConfig.vsyncPol = VPS_VIP_POLARITY_HIGH;
vipPortConfig->disConfig.hsyncPol = VPS_VIP_POLARITY_HIGH;
usecase:

CaptureLink_CreateParams_Init(&capturePrm);
capturePrm.numVipInst = 1; //1个采集口
//capturePrm.outQueParams[0].nextLink = nNullID;
capturePrm.outQueParams[0].nextLink = gVencModuleContext.ipcM3OutId;//gVcapModuleContext.nsfId[0];// gMultiCh_VsrcVencObj.ipcOutVpssId;////下一个linkID
capturePrm.tilerEnable = FALSE; //停用tiler
capturePrm.fakeHdMode = FALSE; //是否启用模拟1080P输出
capturePrm.enableSdCrop = FALSE; //是否启用裁剪 采集为D1时有用 将720裁剪为704
capturePrm.doCropInCapture = FALSE; //是否启用裁剪 采集为D1时有用 将720裁剪为704 通过调整指针的方式实现 //采集通道参数设置
for(vipInstId=0; vipInstId<capturePrm.numVipInst; vipInstId++)
{
pCaptureInstPrm = &capturePrm.vipInst[vipInstId];
pCaptureInstPrm->vipInstId = (SYSTEM_CAPTURE_INST_VIP0_PORTA+vipInstId)%SYSTEM_CAPTURE_INST_MAX;/*ID设置*/
pCaptureInstPrm->videoDecoderId = 0; /* Need to change based on actual HD video decoder */
pCaptureInstPrm->inDataFormat = SYSTEM_DF_YUV422P;//SYSTEM_DF_YUV422I_YUYV;

pCaptureInstPrm->standard = SYSTEM_STD_1080P_30; /* Need to change based on actual HD video decoder */
pCaptureInstPrm->numOutput = 1; /* Need to change based on actual HD video decoder */

pCaptureOutPrm = &pCaptureInstPrm->outParams[0];
pCaptureOutPrm->dataFormat = SYSTEM_DF_YUV420SP_UV;//SYSTEM_DF_YUV420SP_UV;//
pCaptureOutPrm->scEnable = FALSE; /* Need to change based on actual HD video decoder */
pCaptureOutPrm->scOutWidth = 1920; /* Need to change based on actual HD video decoder */
pCaptureOutPrm->scOutHeight = 1080; /* Need to change based on actual HD video decoder */
pCaptureOutPrm->outQueId = 0;
}

Chris Meng：

Liu Jiang,

请问你是否有测量过FPGA输出时钟，同步信号是否正常？你是否有修改过时钟，同步信号的极性，看是否有帮助?

jiang liu4：

回复 Chris Meng:

谢谢您的回复！

我们测试了FPGA的数据，FPGA 时钟为74.25MHz 使用CLK VSYNC HSYNC D[0-15]信号线，VSYNC和HSYNC都为高时数据有效。输出的视频为1920*1080 30帧

现在找到之前采集不到数据的原因了： 我在Vps_captIsrListComplete()回调函数中添加了打印信息。去掉之后就有数据了。

————————————————————————————————————————————–

回到函数所在文件vpsdrv_captureList.c

/* Driver callback called by CLM with timer expires */Void Vps_captIsrListComplete(){ /* get current time */ gVps_captCommonObj.clockTicks = Clock_getTicks();

##########################去除的打印##############################// Vps_printf ( " %s:%d: Driver callback called by CLM with timer expires !!!\n",// __FUNCTION__, __LINE__);

##########################去除的打印##############################

/* trigger list processing task */ Semaphore_post(gVps_captCommonObj.semListUpdate);}

————————————————————————————————————————————–

但是我们有遇到两个新的问题：

1.captureLink采集的过程中会出现数据帧中的pFrame->reserved>0的问题，所以程序一直提示【[m3vpss ] 247926: CAPTURE: Dequeued frame more than once (0,0, b90f6e80)】。我们跟踪了一下代码发现好像是video 中H264压缩部分将pFrame->reserved设置为了当前时间，这个该如何解决啊？

2.第二个问题是，如果设备上电FPGA在HDVPSS初始化之前就给数据信号的话，也会没有采集。我们将FPGA中加了100秒的延迟，在HDVPSS初始化完成之后FPGA再给数据信号（时钟信号一直在给）就能够正常采集。这可能是什么原因导致的？

问题1的错误提示在文件 captureLink_drc.c 中的CaptureLink_drvProcessData函数

针对之前的问题2我们使用CCS查看了vin的寄存器值

FPGA有延迟时，HDVPSS初始化之后FPGA再给数据信号。可以正常采集。

FPGA没有延迟时，上电之后HDVPSS初始化之前就给数据信号，出现如图中的寄存器不同，提示output FIFO PortA Luma Overflow。我们在设备程序启动之后添加了调用采集部分重启的命令IOCTL_VPS_CAPT_RESET_AND_RESTART还是不行。这个问题该如何解决呢？

你好；

        你的fpga的输出是按照cea-861，参考标准时序输出的吗？

        你可以试一下修改采集模式：

pVipCreateArgs->videoCaptureMode = VPS_CAPT_VIDEO_CAPTURE_MODE_SINGLE_CH_NON_MUX_DISCRETE_SYNC_ACTVID_VSYNC;

正常应当是不会有这个问题的；

即使fpga那边一直在输出数据，dm8147的这边的采集应当是没有问题的；

你们怎么会选择IPNC RDK3.5的开发包，不使用DVRRDK的开发包直接开发呢；

jiang liu4：

回复 Ternence_Hsu:

1. 我们买的开发板带的是IPNC RDK3.5的开发包，当时担心使用DVRRDK需要修改很多东西。我们是不是使用DVRRDK更合适。

2.我们现在的程序配置是：

pVipCreateArgs->videoCaptureMode = VPS_CAPT_VIDEO_CAPTURE_MODE_SINGLE_CH_NON_MUX_DISCRETE_SYNC_ACTVID_VBLK; pVipCreateArgs->videoIfMode = VPS_CAPT_VIDEO_IF_MODE_16BIT;

vipPortConfig->disConfig.fidDetectMode = VPS_VIP_FID_DETECT_MODE_VSYNC; vipPortConfig->disConfig.actvidPol = VPS_VIP_POLARITY_HIGH; vipPortConfig->disConfig.vsyncPol = VPS_VIP_POLARITY_LOW; vipPortConfig->disConfig.hsyncPol = VPS_VIP_POLARITY_LOW;

FPGA输出的信号

FPGA的lv和fv为高的时候数据有效，现在我们让FPGA给的测试数据Y和UV数据给的是一样的，并且把FPGA的延迟取消了。

现在设备上电之后，有时候capture能采集到数据，但多试几次就不行。

CCS连接上设备查看寄存器，不出视频的时候中断状态寄存器中OUTPUT_FIFO_PRTA_LUMA_STATUS为1，文档中这一位解释为Output FIFO Port A luma Overflow Status

当能够正常出视频时，连接上设备查看OUTPUT_FIFO_PRTA_LUMA_STATUS为0

jiang liu4：

回复 Ternence_Hsu:

在之前的基础上又设置了下面两个选项并增加了VIP Overflow Recovery后能够正常的出图了，FPGA也不用延迟了。

pObj->enableCheckOverflowDetect = TRUE;pVipCreateArgs->periodicCallbackEnable = TRUE;

并且在Void App_runDemo(Void)函数最后又添加了VIP Overflow Recovery步骤，具体流程在文档 [HDVPSS User's Guide 1.2.8.2.19 VIP Overflow Detection and Recovery]

现在我们将FPGA输出的分辨率修改为4096*960 30帧，时钟是150MHz。能够出图但是图像中从3840往后的uv数据不对，Y数据都是对的。请问DM8147的HDVPSS可以出4096*960 30帧的数据吗，现在我们只修改了capturelink创建时的分辨率，并将数据分辨率设置为了4096*960，这样修改对吗？

jiang liu4：

回复 Chris Meng:

谢谢您的回复

我们将link修改了一样，在capturelink接了nsf，capturelink中不在做YUV转换，在nsf中做YUV转换现在可以出4096*960的分辨率了。
