RT1170: How to configure LCDIFv2 to support video flux from MIPI_CSI to LCDIFv2 then to MIPI_DSI ?

Dear NXP support,

As the following diagrams in i.MX RT1170 Processor Reference Manual, it seems that we can have a direct video flux from MIPI_CSI to LCDIFv2 then to MIPI_DSI.

But no such example in the SDK.

How to configure LCDIFv2 to achieve that ?

Best regards

Hi Zhiming,

I don't get your point.

Could you please provide some useful docs/links ?

Hi,

Unfortunately this features (direct path from camera input to the screen without memory access) has been removed.

It will be updated in the next Reference Manual release.
