Need to run two PAL cameras simultaneously with IMXRT1176

[burhanhagi]

I need to run both front and rear cameras concurrently to get live video. I am using IMXRT1176. I am able to get live video from PAL camera over either MIPI-CSI or parallel 8-bit CSI peripheral. 

For now, I have two different decoders in hand(ADV7280M or TVP5150).  First one has MIPI-CSI and the last one has 8-bit parallel CSI interface to use each peripheral. Also, I have two cameras whose inputs are connected two different analog channels of above decoders. Example with ADV7280M is like below;

By switching analog inputs, I can display either front or rear camera view, but not both.

So Is there any possibility to display two cameras with single IMXRT1176 simultaneously? I have physically both interface in my PCB. Thanks a lot.

Hi @burhanhagi ，

   No, if you use two cameras: one connect to the MIPI-CSI, another connect to the parallel  CSI, yes, it can works, but it can't work simultaneously.

  This is the reason:

You can find, at last, MIPI-CSI and the parallel CSI all connect to the CSI.

So, if customers want to make two cameras work simultaneously, they can use the flexio to simulate another CSI.

This is the application note for your reference:
