Hello,
I'm working on interfacing a MIPI CSI-2 sensor with RPI 5.
Details of sensor Interface:
Data lanes : 4
Pixel Format : YUV422 8-bit
THS-Zero : 170ns
THS-PREAPRE : 59ns
Data Rate Mbps/lane : 600Mbps/lane
As of now In RPI 5 we had already interfaced a Sensor which streams with YUV422 16bit, but now with new sensor it is YUV422 8bit. Now I have few questions related to interfacing
1. How to set pixel format for UYVY 8 bit.
For 16 bit UYVY we could able to run below commands
2. For starting MIPI Frame packets THS-Prepare and THS-Zero timing parameters are very important how to configure them in RPI 5?
3. Same for Data rate how to control it?
