DM368 and OV10633 Issues

Other Parts Discussed in Thread: TVP7002

Hello,

I am attempting to use an OV10633 sensor with the DM368 Leopard board.  I have written a driver for the OV10633 using others as a reference and have the sensor outputting in UYVY Format.  I have the the camera itself configured much like the TVP7002 since setting is_camera will cause it to assume RAW instead of YUV:

{
	.module_name = "ov10633",
	.grp_id = VPFE_SUBDEV_OV10633,
	.num_inputs = ARRAY_SIZE(ov10633_inputs),
	.inputs = ov10633_inputs,
	.ccdc_if_params = {
		.if_type = VPFE_BT656,
		.hdpol = VPFE_PINPOL_POSITIVE,
		.vdpol = VPFE_PINPOL_POSITIVE,
	},
	.board_info = {
		I2C_BOARD_INFO("ov10633", 0x37),
		// this is for PCLK rising edge
		.platform_data = (void *)1,
	},
},

Things seem to initialize good and when i look at VSYNC, HSYNC, PCLK, and Data lines on a scope they all look good however when i run my pipeline i get no frames, it just initializes and sits there:

I tried changing the polarities around, but no difference.  I put prints into vpfe_isr in vpfe_capture.c and they never print out, so it would seem no buffers are being received.  Any clues as to what i should looks at?  I am not sure where to go from here, maybe I am missing settings somewhere?  Or maybe someone has a working OV10633 setup for the leopard board?

    Alright i was able to get this working, I had to set if_type to have an external sync:

    {
	.module_name = "ov10633",
	.grp_id = VPFE_SUBDEV_OV10633,
	.num_inputs = ARRAY_SIZE(ov10633_inputs),
	.inputs = ov10633_inputs,
	.ccdc_if_params = {
		.if_type = VPFE_YCBCR_SYNC_8,
		.hdpol = VPFE_PINPOL_POSITIVE,
		.vdpol = VPFE_PINPOL_POSITIVE,
	},
	.board_info = {
		I2C_BOARD_INFO("ov10633", 0x37),
		// this is for PCLK rising edge
		.platform_data = &ov10633_pdata,
	},
},

    Then i realized I was using the opposite 8 input lines than were set by default so i had to change that (in dm365_ccdc.c):

    @@ -1312,7 +1312,7 @@
 
 	case VPFE_YCBCR_SYNC_8:
 		ccdcfg |= CCDC_DATA_PACK8;
-		ccdcfg |= CCDC_YCINSWP_YCBCR;

 		if (params->pix_fmt != CCDC_PIXFMT_YCBCR_8BIT) {
 			dev_dbg(dev, "Invalid pix_fmt(input mode)\n");
 			return -EINVAL;

    Finally had to get the standard changed.  I feel like there should be some way to do this in my gstreamer pipeline call but i could not figure it out.  In vpfe_capture.c it is set to 0 by default in both the functions 'vpfe_initialize_device' and 'vpfe_s_input' for is_camera=0 devices.  The only other place it can be changed for my is_camera=0 device setup is 'vpfe_s_std', which looks to be called via a VIDIOC_S_STD v4l2 IOCTL call (v4l2-ioctl.c).  This makes me believe there should be some gstreamer setting i can set to pass in the correct standard, but i could not figure it out.  GStreamer 1.0 has a norm parameter on v4l2src but i am using 0.10 which does not have this.  Anyways i just had to hardcode a change into the 'vpfe_s_std' function to change it by calling my querystd function of my OV10633 driver:

    @@ -1873,6 +1873,9 @@

+		ret = v4l2_device_call_until_err(&vpfe_dev->v4l2_dev, sdinfo->grp_id,
+					 video, querystd, std_id);
 	}

    After those changes my pipeline worked and i had good frames coming through!  Is till have to adjust some sensor settings, but when i set it to Color Bar mode i get perfect color bars so my input from it seems to be correctly configured : ).

    If anyone has any idea of how to set the standard through gstreamer so i can remove that last hack I would be pumped to hear it!
