Hi TI expert

I use dvr_rdk 3.0 for our project, my hardware is custom dm8148 board and my video device

connected to VIP1 POARTA , The video format is yuv422, 16bit, with discrete hsync and vsync.

I am able to run vcap_venc_vdec_vdisp usecase . If our video device not stop, the usecase work

well for long time. But if I stop my video device manually (eg: shutdown video device or no hsync and vsync),

the usecase will be report error. The error message is show below.

The error indicates that SharedRegion memory is corrupted. This can happen due to VIP overflow or due to VIP capture writing beyond allocated buffer.

What is the silicon revision you are using.

Do you see any VIP overflow msg when you disconnect the capture.

Check if the following code marked in bold is present in your codebase.Below code ensures VIP will not write beyond configured size.

/dvr_rdk/mcfw/src_bios6/links_m3vpss/capture/captureLink_drv.c

Int32 CaptureLink_drvCreateInst(CaptureLink_Obj * pObj, UInt16 instId)

Hi Badri

Very happy see your reply, thanks you!

1. I use TMS320DM8148BCYEA0, PG2.1

2. Yes, I often see VIP overflow message when start run the usecase, But when I stop

video device, I don't see VIP overflow message, I will check and tell you later.

3. My video resolution is 1600x1200, How to change code to fit my video resolution?

Best Regards.

First configure capture driver maxWidth height to 1920 x 1080 and check you no longer see the memory corruption issue. The 1200 will get cropped to 1080 but this is expected and this is only for test.

To support 1200 maxHeight is difficult as you have to configure the VIP maxHeight as UNLIMITED as only maxHeight of upto 1080 is supported by VIP hardware.

I discussed with Brijesh who is the HDVPSS expert and his advice is :

"The fix is to add x line interrupt in the VIP driver and x line is set to 1201, so whenever this interrupt comes, it is sure that the VPDMA is receiving more than 1200 lines, to in this case, stop the VIP port in the interrupt and restart it. It will still store few more lines, because this is client interrupt, so we could keep buffer of size, 1210 and restart the VIP port when this interrupt comes."

This fix requires a change in HDVPSS driver and is not available in DVR RDK HDVPSS driver package.

DVR RDK HDVPSS has support for xline interrupt. The HDVPSS driver code has to be modified to restart the VIP from the xline interrupt.

Hi Badri

Thanks for your reply.

1. I am sure when stop video device , I didn't see the VIP overflow message. But when start

run usecase , the overflow message show ervery times.

2. I will follow your advice test with 1920x1080 and tell the result later.

Could you capture 1600x1200 resolution successfully?

I am using RDK4.0 and make some modify for capturing 1600x1200.
