DDR2 controler
Hi We are developing our own board with DM365. Most of the board is done according to EVM schematic. The problem is DDR. We are useing the same IC as EVM. However with the same registry setup as in EVM it is not working. I have examined some signals like CLK, RAS, CAS, some data bits, and adrress bits, all seems to be OK. Any suggestion is welcome.

RE: Re: Changing Resolutions
As I know, hardware is not capable to to do this. If you have no problem
with latency, than you can use resizer to resize image before commpression.
If you imput PAL, than resizing will take few ms.
If your sensor is not capable to bin image, than this is one way how to fix
this.
Mvl 401 is LSP 1.30 I suppose.
Best regards

Subject: RE: Re: Changing Resolutions
I don't think it's the sensor as its just inputting a standard PAL
signal.
The reason is I'm using the following commands:
crop.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
crop.c.left = MAX_WIDTH / 2 - captureWidth / 2;
crop.c.top= MAX_HEIGHT / 2 - captureHeight / 2;
crop.c.width = captureWidth;
crop.c.height = captureHeight;
if (ioctl(fd, VIDIOC_S_CROP, &crop) == -1) {
ERR("VIDIOC_S_CROP failed %d, %s\n", errno, strerror(errno));
return -1;
}
But if I try anything else I end up with a corrupt image. Is there an
ioctl command to not use cropping but to use interpolation?
I think I'm using LSP version mvl401 if that makes any sense.
Thanks
Alex

First question is which sensor are you using?
Perhaps you need to change mode specification in driver.
which LSP are you using?
Interpolation will cost some resources. If you have MT9T001 or some
similar,
than the sensor can do it for you.

The system works great but my problem is with the different resolutions within the codec. At the normal 720x540 resolution it gives me the complete field of view, but when I drop down to say 320x240 instead of using the full field of view and only using every other pixel it uses all the pixels in the central 320x240 box of the frame. How do I get the sensor to use the entire field of view when capturing at different resolutions? If that’s not possible and instead I’ll have to do the interpolation myself, what is the most efficient method of copying every other pixel from the input frame to another buffer that I can then use for the JPEG compression?

RE: LSP 2.10 Previewer hung on preview task

Re: ccdc_davinci LSP210
I am not shure that there should be problem with sensor. Because I have no
problem under LSP1.30. All registers on sensor are OK. So there is perhaps
problem with setting off ccdc inside davinci.

Subject: Re: ccdc_davinci LSP210
When you are setting the exposure on a cmos sensor you
have to be careful not to exceed the number of vertical lines that you
have. In other words, if your sensor is capturing 640x480 then you
shouldn't have an exposure greater than 480, this effectively causes
the sensor to drop a frame for you since you have asked it to continue
exposing into the next frame.
Also with some sensors the H-Blank values can get you into trouble too.
Usually in the sensor data sheet there will be a section showing you
how to calculate frame rate. I generally create a spread sheet so that
I can get the frame rate, exposure range and resolution that I want.
In addition, if you have your VPFE set up so that it is asking for more
data than is provided in a single frame, it will show up as reduced
frame rate.
Generally when bringing up a new sensor I start at the input - dump raw
bayer data as captured by the sensor - and bring it up in a program
that can take raw planar data. Corel Paint shop works, as well as
linux 'display". Once you have fixed your input so it looks sane, move
on the the YUV conversion...

How to setup V4L2 for best preformance
Hi I have simple loop trought which is proccessing images from CMOS sensor. Proccessing take sallmost 7ms. In front end I am skipping frames which are older than 1 frame. Still I have latency from input to outpu 120ms and some times more. I am sure that I can not spare significant amount of time in front end. That means that I have more than 2 frames latency on VPBE (I am useing PAL as output 25fps => 40ms/f) Is there some special settings to improve this timing on VPBE. I am useing V4L2.

V4L2display no image
Hi I have made som looptrought with MT9P031 sensor. Previously I have been useing FB for output. To avoid memcpy I have switched to V4L2. After some time fighting pointers and so on. Previewer is useing buffers from V4L2 for output. All seems OK but I can not see any image on screen. I have caught some buffers to files. Data are pretty similar to image data. But still no image on screen. Streaming is on. I have no idea what could be wrong with. Have some one any idea, what could be wrong?

Re: How to use buffers from FB as output buffer from previewer
Thank you for you answer. I want to use buffers of VPBE as output of previewer and than perhaps output of resizer to avoid memcpy operation. Previewing task will be synchronized with VPBE.I have realized that it is not possible to do it with FB driver I need to use V4L2 to get offsets for previewer. The requirement is to reduce latency. Now I am using pipe of CCDC, PREVIEWER(for demosaicing), memcpy and FB. And the latency is about 160ms. Best regards Ondrej Pindroch SoftHard Technology ltd. -Original Message- From: "Jerry Johns" To: Date: Tue, 12 May 2009 20:48:49 -0700 Subject: How to use buffers from FB as output buffer from previewer Let me get this correct: you want to take the output from the previewer engine in the CCDC module, and drive the VPBE display device with the same memory buffers? Although this is theoretically possible, it does not make sense from an implementation perspective – the CCDC module operates on an input clock that is absolutely asynchronous (and possibly at a different rate) with the display output clock. In that regard, the VPBE hardware will continually pick-up at its native display rate data from that memory location; since the production of data into the buffer by the CCDC is not in ‘sync’ with the VPBE, you’ll definitely get tearing at the VPBE output. What is driving this requirement for single buffer access? Is it memory usage? Latency?

How to use all patches
Hi folks I am new to linux programing, kernel building and so on. I have installed MV4.0.1 from DVSDK. I saw lots of patches on this forum. My question is how to use this all patches, or it is possible to download patched kernnel with drivers? Thank you for your answer.

Video source for DVEVM 6467
Hi I have one question. What are you useing as source for EVM. We have DVD player with full HD, HDMI to COMPONENT converter. But this box turn off output when HDCP detected. Is there any possibility to create component 720p with this gagets? Or should we buy computer and DVI to HDMI cable.

RE: DVEVM 6467 no signal on output
Thanks Phill Unfortunately there is no possibility to set video outputs via bootargs. I can change sources. But now I have no signal on all outputs. Really funny is that, I have tested the whole DEMO one week ago. It works. Than I was away. Monday I returned to work and I have no signal.

I would check your boot arguments - I would have expected a x=component (where x is some module parameter or other) in the boot line or is it the default on the 6467 (I don't have a 6467 board to try here)? Just checking your kernel output and it says 'ch0 default output "COMPOSITE", mode "NTSC"' which backs up this idea.

Re: booting a new board
You have more options to do it. One is via JTAG. The othe one is via UART Reed documents SPRAAI0.pdf and SPRAAI4.pdf. There are some hints how to flash all that via UART. Good luck.
