i.MX8 Multi-Camera EVS

xu_ji1 — Mon, 27 May 2019 09:32:28 GMT

Hello,

In auto-ga 2.1 release android user guide introduce Multi-Camera EVS function and have one sentence:

"This function is only available on the i.MX 8QuadMax MEK board. The i.MX 8QuadXPlus MEK board only supports one
camera."

I want to know what is diff with 8QM and 8QXP,why 8QXP only support one camera?

Thanks

Hi Xu

in general i.MX8QXP can support two cameras, but MEK board seems only one

according to Fact Sheet

https://www.nxp.com/docs/en/fact-sheet/IMX8QADXPLUSFS.pdf

8QM has two MIPI-CSI modules

8QXP has one MIPI-CSI module + 1 parallel camera.

add support for more camears yourself.
