DS90UB936-Q1: 913+936 configuration

Hi Amelie, 

I assume these are all writing to the 936. Without knowing the bandwidth of the imager, I cannot verify the CSI-2 rate and please check section 7.4.2 for operating in raw mode. 

{0x4C,0x01} // RX0

{0x6D,0x7F} //CSI-config,Coax, RAW10

{0x58,0x58} //2.5 Mbps BC, I2C pass through, CRC enabled

{0x70,0x1F} //YUV422 RAW10

{0x1f,0x02} //800 Mbps CSI-2 rate

{0x33,0x01} //Enable CSI output/4 lanes

{0x21,0x04} // basic synchronized forwarding

{0x20,0x20} // disable RX port 1 forwarding

{0x7C,0x38} // Normal RAW10, truncate frames, LV,FV polarity low

Thanks,

Hi Sally,

Thanks for your reply.

May I ask if customer use YUV422 RAW8, are there the same configuration as YUV422 RAW10? 

I saw the following description about YUV422.

DVP RAW8 data format is also supported in serializer RAW10 transmit mode with 8/10 data input bits (MSB or
LSB) connected to the serializer DVP source. DVP format serializer inputs must have discrete synch signals.

Hi Amelie, 

For RAW8 you will want to ensure 954 is set to RAW10 mode and then use register 0x7C[7:6] to enable 8 bit processing. Make sure to match the upper/lower setting so it corresponds with how the 933 inputs are used from the imager. 

Also you will want to change register 0x70[5:0] to match the CSI-2 format for RAW8 which is 0x2A.

Thanks, 

Sally

Hi Sally,

Here is the display. The color seems strange. Which configuration do we need to change?

Hi Amelie, 

Can you read back register 0x4D, 0x4E, 0x55, 0x56, 0x0x7A, and 0x7B on the 936? 

Can you also send me this information so I can send you an internal pattern generation script? 

I need active vertical, active horizontal, frame rate, VC-ID, vertical back porch, and vertical front porch.

Thanks, 
Sally
