Hi Subbaro

I am not aware of parallel camera dts for i.MX7, but as it has the same CSI module

as i.MX6UL, SL one can look at its dts:

linux/arch/arm/boot/dts/imx6ul-14x14-evk-csi.dts

imx6ul-14x14-evk-csi.dts\dts\boot\arm\arch - linux-imx - i.MX Linux kernel

imx6sl-evk-csi.dts\dts\boot\arm\arch - linux-imx - i.MX Linux kernel

About preview function in i.MX6SL.

Best regards
igor

Hi Igor,

Thanks for your reply.

Input available to CSI interface is RGB24, i,e 24 bits / Clk.

In iMX7 Reference manual, section "13.3 CMOS Sensor Interaface" it is mentioned that it supports RGB24. But when I captured a frame from the CSI interface it is not as expected.

What is the CSI register configuration required to enable RGB24 capture.

Thanks,
Subbarao.
