Hi Xiuyang,

Can you specify what problems you are seeing between the 934 and 935?

Regards,

Cindy

Dear Cindy

Currently the i2c address between 934 and 935 can be read, but there is a problem with the final graph, which only shows a few lines. Is there a default serdes configuration for 934 and 935,960 and 395, thank you

Help evaluate the output of CSI-2, bandwidth 1920X384X50

We do not recommend disabling the watchdog timer in DES Reg 0x07.

Is the datatype YUV422 8-bit mode? If so, you will need to configure whether the deserializer will process the upper or lower 8 bits in Reg 0x7C PORT_CONFIG2 bits[7:6]. I will also need to confirm the data type to help calculate the CSI-2 bandwidth going into the serializer.

Double check that the frame valid and line valid polarity is correctly set to align with the imager.

hello

No 0X7C found in 934

The current output format is yuv422 8bits,Could you tell me how to modify it

Hi Cindy

Our current scheme is to use 935+934 to transmit YUV422 8bits. May I ask whether it is supported? If not, is it feasible to use yuv422 10bits

Hi Xiuyang,

As mentioned above, 8-bit format is not supported. However, you can use YUV422 10-bit format. 

Regards,

Cindy
