Unable to capture any data on a sensor with CFA Options of RCCC or RCCB

Hi.
I have a sensor AR0220 with one of these CFA options (I have 2 sensors one RCCC and one RCCB).

I have migrated/modified the code of another sensor driver (regarding i2c commands).

looking at the oscilloscope when trying to get data from the camera , I see data comming out from the 4 lanes.

question is what are the values of these fields in the dtsi

csi_pixel_bit_depth = "12";
mode_type = "bayer";
pixel_phase = "rggb";

when looking at the log I see these messages

[  +0.486630] tegra194-vi5 15c10000.vi: <i>no reply from camera processor</i>
[  +0.000146] tegra194-vi5 15c10000.vi: vi capture dequeue status failed

looking at this snippet

static int extract_pixel_format(
	const char *pixel_t, u32 *format)
{
	size_t size = strnlen(pixel_t, OF_MAX_STR_LEN);

	if (strncmp(pixel_t, "bayer_bggr10", size) == 0)
		*format = V4L2_PIX_FMT_SBGGR10;
	else if (strncmp(pixel_t, "bayer_rggb10", size) == 0)
		*format = V4L2_PIX_FMT_SRGGB10;
	else if (strncmp(pixel_t, "bayer_grbg10", size) == 0)
		*format = V4L2_PIX_FMT_SGRBG10;
	else if (strncmp(pixel_t, "bayer_bggr12", size) == 0)
		*format = V4L2_PIX_FMT_SBGGR12;
	else if (strncmp(pixel_t, "bayer_rggb12", size) == 0)
		*format = V4L2_PIX_FMT_SRGGB12;
	else if (strncmp(pixel_t, "bayer_wdr_pwl_rggb12", size) == 0)
		*format = V4L2_PIX_FMT_SRGGB12;
	else if (strncmp(pixel_t, "bayer_wdr_dol_rggb10", size) == 0)
		*format = V4L2_PIX_FMT_SRGGB10;
	else if (strncmp(pixel_t, "bayer_xbggr10p", size) == 0)
		*format = V4L2_PIX_FMT_XBGGR10P;
	else if (strncmp(pixel_t, "bayer_xrggb10p", size) == 0)
		*format = V4L2_PIX_FMT_XRGGB10P;
	else {
		pr_err("%s: Need to extend format%s\n", __func__, pixel_t);
		return -EINVAL;
	}

	return 0;
}

Seems that these are the only possible values (unless you develop some code above the sensor drive).

TIA

hello moshe.arad,

we don’t support RCCC and RCCB bu default, you should customize your kernel driver to add extend format supports,
thanks
