I try to modify tvp5150.c for i.mx6 board.The input is PAL video source.


The serial port print the message as follow.

TVP5150 io_init

tvp5150_probe:tvp5150 probe i2c address is 0x5D

TVP5150 Chip version = 0x04

   type is 2 (expect 2)

   num ioctls is 13

In MVC: mxc_v4l2_master_attach = tvp5150 = mxc_v4l2_cap1

sdata->csi = 0

cam->csi = 1

tvp5150  mxc_v4l2_master_attach: csi doesn't match

In MVC: mxc_v4l2_master_attach = tvp5150 = mxc_v4l2_cap0

sdata->csi = 0

cam->csi = 0

tvp5150  mxc_v4l2_master_attach: csi does match

tvp5150  mxc_v4l2_master_attach  type is 2

PAL video source.

tvp5150  mxc_v4l2_master_attach  attach___attach___attach

tvp5150  v4l2_int_device_register succeed.

mxc_v4l2_output mxc_v4l2_output.0: V4L2 device registered as video17





When I execute the test command ./mxc_v4l2_tvin.out   -ow 720 -oh 480 -ol 10 -ot 20 -f YU12 in linux.

It occurs the errors as follow and can't display  on screen.

The  ioctl_g_ifparm as follow:


static int ioctl_g_ifparm(struct v4l2_int_device *s, struct v4l2_ifparm *p)


  dev_dbg(&tvp5150_data.i2c_client->dev, "In tvp5150:ioctl_g_ifparm\n");

Who can help to fix the problem?
