IPU Bypass

[subinsebastian]

Board:- Custom i.MX6DL board

BSP:- imx_4.1.15_2.0.0_ga

Camera Sensor : ov5640

I see that the existing drivers have the IPU drivers in between performing format conversions. Is it possible to bypass the IPU completely, and pass the data output by the sensor as it is to the userspace?

Hello Subin,

>>Is it possible to bypass the IPU completely, and pass the data output by the sensor as it is to the userspace?

No, it is not.

you can think CSI is a part of IPU, IPU_CSI1 , IPU_CSI2. so you can't separate CSI and IPU.

Hope the information is helpful to you.

Now that is understood. Let me go ahead and ask, is it possible to put the IPU into some sort of a pass-through mode?

Configure it to not process any incoming data, but transfer everything from the MIPI side, directly to memory?

Hi Subin,

See the diagram from Reference Manual,please!

Obviously, data stream from MIPI CSI-2 also gets to CSI0/1 port via mux.

You can get more information from reference manual.

Have a nice day!
