Hi,

I am using the imx53 AI board to capture NTSC input from adv7180.

And i use the default linux BSP.

But when i run the /unit_test/mxc_v4l2_tvin.out,

I get the wrong result.

The right result is all color is yellow.

but the out put on display had 4,5 vertical green line。

I attached the file, is there someone have any ideas about this?

I think this is a problem of adv7180  output.

Thank you very much!

Hi,

Please, try to use the latest release: L2.6.35_MX53_ER_1109_IMAGE

with patches: IMX53_LINUX_1109_BSP_PATCH

Both are found at Freescale website: http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=i.MX535&nodeId=018rH3ZrDR988D&fpsp=1&...

I tested it and I haven't seen any problem.

Hi Gao,

What board you mean by (Al board), is it the Freescale Automotive Board?

Could you let me know the BSP version are you using? (You can tell me the name of BSP package tar.gz file)

ADV7180 driver should be : linux_topdir/media/video/mxc/capture/adv7180.c

not : linux_topdir/driver/media/video/adv7180.c

Please confirm which adv7180 you are used.

Did you connect the camera?

If it is possible, could you attach a picture captured by camera.

Hi,

I use linux_topdir/driver/media/video/mxc/capture/adv7180.c and capture data from adv7180.

The input of adv7180 is NTSC data.

below is the input data to adv7180:

NTSC_input.png

But my captured data is:

captured.png

There are 4,5 lines on picture.

Note that this test is on the default linux BSP of AI board, and i do not make any changes.

I think you can also reproduce this on your freescale AI board.

Thank you!
