The TX2 camera driver format issue

Autonomous Machines Jetson & Embedded Systems Jetson TX2

HI
I want to support two cameras on tx2 devboard, I have modified following code and resolved incompitable issue of MEDIA_BUS_FMT_YUYV8_2X8,However, when I config MEDIA_BUS_FMT_Y8_1X8, the kernal is corrupt.
I have added on: /drivers/media/platform/tegra/camera/camera_common.c

{
		MEDIA_BUS_FMT_YUYV8_2X8,
		V4L2_COLORSPACE_SMPTE240M,
		V4L2_PIX_FMT_YUYV,
	},
	{
		MEDIA_BUS_FMT_Y8_1X8,
		V4L2_COLORSPACE_SMPTE170M,
		V4L2_PIX_FMT_GREY,
	},

Here are the error:

Could anyone kindly advise if I should modify anywhere else to make TX2 support MEDIA_BUS_FMT_Y8_1X8?

Thank You

2

Did you have modify any other files, I can boot normally with the kernel add that two formats.

3

I didn’t modify the other files. I only changed camera_common.c ,

4

Can you solve this problem,I have the same question.

5

Did you use 28.1 or 28.2DP, I check the 28.1 didn’t have this problem didn’t try 28.2 yet.

6

sorry , I am trying solve this problem now

7

yes , I use the 28.1, at chann. c , I found chan->fmtinfo->fourcc is invalid value, but I don’t know why

8

Hi

a similar problem
I use TX2 and driver package R28.1

Added to driver (based on ov5693) MEDIA_BUS_FMT_YUYV8_2X8

I have added on: kernel/kernel-4.4/drivers/media/platform/tegra/camera/camera_common.c

{
   MEDIA_BUS_FMT_YUYV8_2X8,
   V4L2_COLORSPACE_SMPTE170M,
   V4L2_PIX_FMT_YUYV,
},

added on: kernel/kernel-4.4/drivers/media/platform/tegra/camera/sensor_common.c

else if (strncmp(pixel_t, “uyvy”, size) == 0)
*format = V4L2_PIX_FMT_UYVY;

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)

in principle, is it possible to add this video format to the package R28.1 or R28.2?

Thank you in advance.

18321083174/visiondev,
One question - are you guys adding a YUV or bayer format sensor for your development? If it’s former, is it a CSI interface or USB interface? Thanks.

How can I solve it? Thank you.

Hi
you need modify another file to add your fmt,I am sorrt I forget the file name,if you add this,you can solve the problem(the tx1 and tx2 file name is disaffinity)

12

Thank you, can anyone else know how to solve it?

13

I would suggest to move to J4.2.1 that release have add the YUV format supported.
