Actually the knowledges on the Linux side will sooner or later _OR_ more or
less become public assets. The difficult part of almost every embedded project
resides in the vendor specific portion. Like for davinci, it is not TCP/IP that
causes confusions, it is the davincifb, resizer, dsplink, cme
The VPFE modules in CCDC and IPIPE expects to deal with only the
RGr/GbB pattern. That is why there is a data formatter and
color space conversion at the input of CCDC. In your case you would
need to do data formatting to re-order the pixel bytes while
reading out from CCDC input line buffer. Ther
Manas,
I have come across the same problem and was wondering you if you
had found a solution. I am using the dm355 with version 1.3 software. And
when attempting to build the kernel I've found the instructions don't match
the folders I have. Have you or anyone else found a solution to

Stephen,
Thanks for that idea! My colors are looking correct now.
I ended up using:
ipipe_hst = 0;
ipipe_vst = 1;
I saw what they were doing in the driver with COLPTN but I figured that
they were just hardcoding to the Micron imager, not that it wouldn't matter.
Thanks,

You can make the CCDC capture the data pattern that you need by skipping
one row and one column. Another way to do it is to skip them in the
IPIPEIF interface
ipipe_hst = 1;
ipipe_vst = 1;
Row and column skipping should give you the RG/GB pattern that the
RAW->YUV interface needs for proper c
Hi,
There have been some questions in the past on this list about whether DSP-side
development can be done on Linux.
This is FYI for those who may not be aware ... DSP-side development tools are
available on Windows (as part of CCS) and also on Linux (as standalone
downloads).

I'm having trouble getting the correct color output on my display and
I'm wondering if I'm setting up the CCDC or the IPIPE incorrectly on the

The imager sensor is a Omnivision 3630 which has a bayer pattern of:

Does anyone have any suggestions/experience on how to convert an

Any practical experience on how to start with or any link to available
tutorial?
Thanks,

Hi,
i wonder if there are any documents mentioned about each procedure of
encoder/decoder's execution time on Davinci ARM side and DSP
side respectively.
take H.264 encoder as example, the procedures are Motion Estimation (ME),
DCT, Quantization... etc.
i am surveying the codec procedures' exec
Swami,
Well done! Thank you!
That's really a good news :)

Just wanted to give you a head up on the USB DMA feature on
DaVinci. I have USB DMA running on my setup on 2.6.25 git on our DaVinci EVM
environment as USB host.
Still would require some more coding style and naming cleanups. I think I can
publish the patch in the later half
