Hi ChuanZheng, 

Please provide at least a high level block diagram of what your use case is. Include any GPIO's, what mode you will be using (RAW10/12), etc. 

Thanks,

Sally 

Hello Xue, 

What MIPI CSI-2 rate do you intend to use on the 954 side?

Best Regards,

Casey 

954 intend to use 800 Mbps

Hi Xue, 

Please see below. You will need to determine what is correct for 0x6D based on your 913 config. Also, are you sure the data type is YUV422 for 12 bits? The pixel packing structure is not similar.

desAddr = 0x??
ser1Alias = 0x??
ser2Alias = 0x??
cam1Addr = 0x??
cam1Alias = 0x??
cam2Addr = 0x??
cam2Alias = 0x??

WriteI2C(0x4C,0x01) #write enable for RX0
WriteI2C(0x58,0x58) # 2.5 Mbps
WriteI2C(0x5C,ser1Alias) #SER alias RX0
WriteI2C(0x5D,cam1Addr)
WriteI2C(0x65,cam1Alias) #Cam alias RX0
WriteI2C(0x6D0,x7D or 0x7E) #Check mode on 913???
WriteI2C(0x70,0x1F) # YUV42210B VC0 ???

WriteI2C(0x4C,0x12) #write enable for
WriteI2C(0x58,0x58)
WriteI2C(0x5C,ser2Alias) #SER alias RX1
WriteI2C(0x5D,cam2Addr) # 2.5 Mbps
WriteI2C(0x65,cam2Alias) #Cam alias RX1
WriteI2C(0x6D0,x7D or 0x7E) #Check mode on 913???
WriteI2C(0x70,0x1F) # YUV42210B VC0???

WriteI2C(0x1F,0x02)
WriteI2C(0x33,0x01)
WriteI2C(0x21,0x01)
WriteI2C(0x20,0x00)

Hi, Sally

Mipi seems has data, but soc can't get the video.

I want to use  Fixed Color Patterns to test first, how can I setting the registers. I want to use YUV422B8 VC0 to try test pattern.

Hello Xue,

If you can use the graphical Analog LaunchPad interface connected to 954, then there is an easy way to configure the pattern generator: https://www.ti.com/tool/ALP 

If you can not use the SW on your end, please provide the video parameters above and we can help you generate the registers 

Best Regards,

Hi Casey,

I tested pattern mode is okay.

The sensor data got from DS90UB913Q is yuv422 12bit, how to set it?

Hello Xue,

There is no such format as YUV422 12 bit in the CSI-2 standard. Can you please clarify the sensor data format, maybe with a picture of the data stream from the datasheet? 

Best Regards,

Casey 

Hello Casey，

     I contacted the sensor module vendor,  and got some info from them. It seems some issue for the info:

serializer RAW12 transmit mode with yuv422 10bit

For my understanding from DS90US954, this is unsupported, pls help confirm it
