Hi,
I'm trying to configure a 2 MP sensor to able to run at 60 fps, but i get some trouble.
I m able to get video streaming at 30 fps.
I think my problem comes from the mipi configuration.
How to get the V-Blanking and H-blanking ? These datas change when we switch to 60 fps ?
Thank you,
JZ

JZ,
Yes, you have to change the output parallel data bus width to 16. Because the the maximum clock at which the parallel output drives is 100 MHz.

Hello,
Yes, Blanking times change when you change the fps. Is the sensor manufacturer not provided this information?
Please let me know the CX3 MIPI configuration for 30 fps and 60 fps - CX3 MIPI tool Screenshots.

Thank you for your reply Sridhar !
I just get the response from the manufacturer, so :
CSI Clock : 400 MHz
H-Active : 1600
H-Blanking : 193
V-Active : 1300
V-Blanking : 159
FPS : 60.0
Data : RAW8
We get this screen from the configurator :
For 30 fps, I use this config :

I found a way to make it work by using this configuration :
Changing the output to 16 bit of the mipi block (I think this allow the GPIF to treat 16 bits in once clock pulse, so we divide by 2 the time).
