Hi, all
My platform have the FPGA modules as the video source, and I could get the
video stream as the BT 656 format, and It works very well.
Now I want to capturing the video stream as the Raw Data format from the
FPGA modules, but I do not know how to change the davinci_vpfe.c to
set the ccdc
Hi, all,
I want to use the VPFE as generic YUV configration format in DM6446, and my
program is running in Linux,
So could anyone tell me how to append the davinci_vpfe.c or other files in
Linux driver?
Thank you~~

Hi, all
I developed several Network Cameras base on DaVinci DM6446 platform, but I
found that when I connect them on the same network,such as 192.168.0.xxx
When I power on them, I found that I can not ping them at the same time.
That means when I make only one Camera working, I could ping it well,

I want to use the JRTPLIB in my encode project base on DM6446 platform, but
I donot know how to use the c++ library in the C project,
could anyone give me some information about how to use the cpp file in the c
project?
how to use the jrtplib in the encode project? Now I have the *.h files
There is a solution that is mentioned by the year of 2007:

That will help the UART1 drivers.

Hello Zhang,
I think you need to change the option in struct
nand_davinci_platform_data nand_data,
.ecc_mode = NAND_ECC_SOFT, to use s/w ECC.
