IMX6Q wtih adv7611

[kimsuhak]

Im using Imx6q sabreauto board.

Im trying to add adv7611 to this.

adv 7611 is BT656 4:2:2 8-Bit and connected  CSI0.

but I faced this error messages,

Am I missing something??

(I can email u my device driver, if u want)

I solved mxc_v4l_dqueue timeout enc_counter 0 problem with your reply.

but the images are never shown.

I changed CSI timing/data mode protocol to gated mode.

I changed color mode to YCrCb to RGB now,

I tested like this,

/opt/unit_tests/mxc_v4l2_overlay.out -iw 1280 -ih 720 -ow 1280 -oh 720 -fr 30 -di /dev/video0 -fg -f RGBP

my device driver is based on ov5640. and use 8 bit.

my kernel is 3.0.35. I think, it does not support 16 bit mode (mxc_v4l2_capture.c). right?

Dear Kim, can you email your driver?..

I am developing a device on imx6q with both adv7611 and adv7181c chips and have solved problems with 7181 already.

Alex.

[igorpadykov]

right, default kernel 3.0.35 does not support 16 bit mode.
