Virtual channel support on IMX8Mn

[extnc]

Hi, may i know IMX8Mn supports virtual channel id ? I am confused because some of the forum says "MIPI CSI-2 of  i.MX8M/MINI doesn't support virtual channel", but i can see "MIPI_CSI2 Supports 4 channel virtual channel or data interleave" in IMX8MNRM-reference_manual.

Usecase:

-Connected 4 cameras to imx8mn . Need to know  which camera captured the image.

Thanks a lot for your answers.

Hi,

Thank you for the replay, please find the details of the reference manual.

I compare with v2 and v0 reference manual, this sentence is new for v2, for imx8mn mipi csi, which is the same IP as imx8mm, should support deinterlace but not support virtual channel, this is HW limitation
