Xavier support raw14

[syan]

Hi All,

I’m working on JetPack4.4, L4T32.4.3

I want to use V4L2 capture RAW14 image

According to this post to modify

RAW14, RAW16 in ISP pipeline

Hi Jerry, yes I’ve added support for raw14 like this: //videodev2.h #define V4L2_PIX_FMT_SGRBG14 v4l2_fourcc('p', 'g', 'E', 'E') //v4l2-ioctl.c static void v4l_fill_fmtdesc(struct v4l2_fmtdesc *fmt) { ... case V4L2_PIX_FMT_SGRBG14: descr = "14-bit Bayer GRGR/BGBG"; break; ... } //camera_common.c { MEDIA_BUS_FMT_SGRBG14_1X14, V4L2_COLORSPACE_SRGB, V4L2_PIX_FMT_SGRBG14, }, //sensor_common.c else if (strncmp(pixel_t, "bayer_grbg14", size) == 0) *format = V4L2_PIX_FMT_SGRBG14; /…

only different is vi4_formats.h for TX2, and I modify vi5_formats.h for AGX Xavier

But it still doesn’t work…

Have any ideas?

What’s your status? Driver probe without problem?

[syan]

Yes. Because I removed i2c.
When I set V4L2_PIX_FMT_SRGGB12 , it can work.

Get the trace log for the RAW14 case to check.

Hi ShaneCCC,
I’m trying another way to check RAW14 can work or not.
By this command:
v4l2-ctl -d /dev/video0 --set-fmt-video=width=2592,height=1944,pixelformat=RG14 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=1 --stream-to=test14.raw

And it work well!

Then I use c code to to same thing, it will got

And Then check /include/uapi/linux/videodev2.h had added V4L2_PIX_FMT_SRGGB14

How can I do next?

[ShaneCCC]

Suppose it could be the /include/uapi/linux/videodev2.h didn’t include in your code.
