About "MIPI CSI2 YUV422 8-bit data type" support

Hi Sir,

Check the Jetson Orin Nano Series Modules Data Sheet . See the following statement in “2.5.1 MIPI Camera Serial Interface (CSI)”:

Supported input data formats:
• RGB: RGB888, RGB666, RGB565, RGB555, RGB444
• YUV: YUV420-8b (legacy), YUV420-8b
• RAW: RAW6, RAW7, RAW8, RAW10, RAW12, RAW14, RAW16,

Miss the “YUV422 8-bit”

Does the Jetson Orin Nano support YUV422 8-bit ? Or just typo ?

3

Right should be YUV422-8 bits instead of YUV420.

Thanks

I know that YUV420 also is as the data type in MIPI CSI2 spec.

YUV420 also should be supported by Orin Nano platform, right ?

6

Yes, the HW spec support that,.
However, current driver only support YUV422-8bit.

Hi Sir,

“current driver only support YUV422-8bit.” mean that YUV420 are not listed in vi5_video_formats (nvidia-oot\drivers\media\platform\tegra\camera\vi\vi5_formats.h), right?

If add the “YUV420” configurations in vi5_video_formats, the driver will support YUV420, right ?

Yes, suppose you can add it by modify the kernel driver.

Thanks
