Hi, In our current setup we use the DPHY440s in single lane mode, connected from OV680. But the register sets that you have mentioned above for HS mode on lane 0 are not available in the datasheets. Could you please share the details for the complete register set.

Hi,

The DPHY440 registers are used for internal debugging purpose and I can't share it. Are there any additional details you would like to know regarding the register steps I provided?

Thanks

David

Hi,

In our setup, while running the test pattern from the camera, the output image is distorted. Hence we tried to set the registers mentioned in this thread, and the image streaming stopped. Would be helpful to know if there is any other settings that need to be done on the DPHY440s.

BR,Divya

Do you have a scope measurement waveform at the DPHY440 output? What EQ, VSADJ_CFG0 and PRE_CFG1 are you using?

Can you also share your schematic and layout?

Thanks

David
