ADV7181C connected to 16bit CSI

[mks]

Hi,

We are working with ADV7181C to get video from SVGA PC output (800x600@60Hz). The CSI is connected through :

CSIx_DAT4 ~ CSIx_DAT9

CSIx_DAT12 ~ CSIx_DAT19

We have set ADV7181C register's properly to output 16-bit YUV 4:2:2 as follow :

Then we applied patch from https://community.freescale.com/docs/DOC-97981.

But when we try to get frames with the following command :

~# ./mxc_v4l2_capture_sgrbg8 -ow 800 -oh 600 -c 500 -fr 25 testsgrbg8.bin

in_width = 176, in_height = 144

out_width = 800, out_height = 600

top = 0, left = 0

sensor chip is adv7180_decoder

sensor supported frame size:

720x576

     Width = 800     Height = 600     Image size = 960000

pixelformat: GRBG

VIDIOC_DQBUF failed.

VIDIOC_QBUF failed

We get timeout error (complete log) :

Hi kamel,

     Have you got adv7181c work with iMX6? I got the same problem, could you share the solution? Thanks。

[igorpadykov]

Hi kamel

for ADV7180/bt656 one needs to use mxc_v4l2_tvin, also

one can look at below activities

Re: ADV7180 on IMX6 giving magenta output

Hi Igor,

Im using mxc_v4l2_capture to because tvin doesn't have redirection to binary file, only display on framebuffer is supported.

We have both adv7180  and adv7181c, the first work well with default bt656 mode with a cvbs input but with adv7181c, we need to capture a svga/xvga input so we can't configure adv7181c with bt656 (look at SDP vs CP).

Is there any application note on how to properly set csi with 16-bit generic data ? What configuration should I have in registers CSI0_SENS_CONF, CSI0_SENS_FRM_SIZE, CSI0_ACT_FRM_SIZE and CPMEM ?

There is a lot of discussion but no one gives a correct answer or scheme to follow ?

[igorpadykov]

Hi kamel

I am afraid there are no such documents, link below is for

16-bit generic data
