Camera RAW format support

yashavanthashet — Fri, 02 Nov 2018 14:06:20 GMT

Hi,

We are using i.MX8M custom board with Linux4.9.51_ga release.

We are using camera which supports only RAW format, we have ported driver for same keeping ov5640_mipi as reference.

But we are unable to set RAW format, only YUYV support we are able to do which our camera doesn't support.

Kindly let us know the procedure to change it to RAW format.

Thanks in advance,

Regards,

Yashavantha

Hello,

Currently, we do not have any guide of how to port a raw image sensor. However, if you can visualize your sensor on your devices at the kernel level. Probably the below guide can help, unfortunately, that guide was made by the image sensor that we support. Hopefully can help you.

Dear Deigo,

Thank you.

Also one more query, Is there any changes required for changing to data lanes to 4 other than below changes in dts.

                mipi_csi1_ep: endpoint {
                        remote-endpoint = <&imx230_0_ep>;
                        data-lanes = <1 2 3 4>;
                };

Thanks and regrads,

Yashavantha

Hello,

Supposedly, how you are configuring the dtb should be enough. However, please be sure that your driver is working correctly.
