Linux/DS90UB954-Q1: DS90UB913 -----> DS90UB954-Q1

May I ask which register is configured incorrectly?

Hello,

please change register 0x58 in 954 from 0xD6 to 0x58.

Also, which Mode are you using in the 913A?

Hello, I modified the following, oscilloscope test mipi-clk still has no waveform.My MODE is:

10-bit mode, 20 to 100 MHz PCLK, 10 to 10 bit DATA + 2 SYNC

Are you initializing your Image sensor correctly? Can you measure the signals comming out of it into the 913A?

Are you configuring the correct SER Alias and Sensor ID and Alias in reg 0x5C, 0x5D and 0x65?
Can you see the correct SER ID in reg 0x5B?

Please do the following changes in your initialization:
Change regsiter 0x21 from 0xBC to 0x81
remove writing to reg 0x7C
remove writing to reg 0xBA
remove writing to reg 0xBC
remove writing to reg 0x4A
Change register 0x70 from 0x1F to 0x2B
remove writing to reg 0x1E

Thank you for your reply. According to what you said above, oscilloscope detects that csi2-clk has waveform, but there is no waveform on csi_d0p. Is it normal?The 913 camera I'm using now outputs images when it's powered up and works without initialization.

If you can measure at the 954 CSI outputs only clock but no data, that means your camera is not sending the video stream.

Can you please answer my other questions? copying them again.

1) Are you initializing your Image sensor correctly?

2) Can you measure the signals comming out of the sensor into the 913A?

3) Are you configuring the correct SER Alias and Sensor ID and Alias in reg 0x5C, 0x5D and 0x65?

4) Can you see the correct SER ID in reg 0x5B?

Thank you very much for your reply.The position I measured above is wrong. According to the above configuration, there is already output.But it's green.I have confirmed that the format of the camera is YUV422 and RAW8.Could you please tell me how to modify register 913? I didn't see it in the manual.Here is my script:

Why are you using the address 0x2E for the 954? This is not valid. Please refer to the d/s table 15 for choosing the settings for the correct IDx.

- Remove writing reg 0x0D --- you do not need to override IO supply mode detection.

- Remove writing reg 0x18 --- using only one camera does not require Frame Sync.

- Remove writing reg 0x72 --- this is valid only if your Serializer is a CSI device (953, 935...)

Move writing reg 0x33 and reg 0x20 to the end of initialization.

- Remove writing reg 0x34 --- you can keep the default

- reg 0x7C -- why are you changing the polarity of Frame Valid signal?

Which 8 bits are you using on the 913A side, upper 8 or lower 8 bits?

Also please refer to the 954 data sheet section 7.4.2 and 7.4.3 to setup your 954 to the correct DVP Mode.

Double check the resistor values in your design and compare them with table 2.
