Multiple Cameras on iMX8M Mini

leecb — Thu, 30 Jan 2020 15:44:46 GMT

We are planning to upgrade an old imx6Q product to (likely) imx8m mini. We wish to support 2 MIPI Cameras (probably OV5640). On imx6Q this seemed possible but on imx8 mini the MIPI CSI2 doesn't support virtual channels. Does this mean we can only use a single camera? thanks

Hello Lee,

The i.MX8Mmini Support up to 4 lanes of MIPI, please take a look at the Reference manual:

Thanks Bio_TICFSL. But how do I connect 2 x 2 lane MIPI cameras to 1 x 4 lane MIPI CSI input? Which one provides the clock? How does the imx8m mini know what to do with the 2 cameras?

Hi Lee Coppins-Brown,

I'm facing the same problem "Using multi cameras with IMX8M Mini". Because IMX8 doesn't support virtual channel, I don't know how to split data. Do you have any solution?

Best regards,
