3 problems
use v4l2 command capture one frame, but the raw file is in a mess, and the size is 300KB. we communicated with camera FAE, and got replay that the size should be 250KB. what`s more FAE verified that all registors are setted well. So, can any one help to give advices?
Hi @ShaneCCC
The media bus format of our sensor is “Y8_1X8”. The sensor works well at 1280X800 mode (Have reference to the topic). But, at 640X400 mode, the frame goes wrong.
So, I think the format is right. Could you give more advices.

Hi @ShaneCCC
How to config alignment, so that make the sensor fit for 640. Should DT, such as pixel clock, mclk multiplier, etc, be configed?

In the following camera architechture, sensor is connected directly to the V4l framework. So i wonder will the vi module influence the raw file?Because, we use V4L command to capture a frame.
