DS90UB962-Q1: Processors forum

Hello, 

Do you have 2x 933's connected to the 962? Are you noticing an error on the display as well, or only register error?

Thanks, 

Sally 

Hi.

No display, only register error

I'd like to describe the phenomenon again. Before power on, if four cameras are connected, after the display is normal, the four cameras can exchange with each other to restore the display normally. If there is only one camera connected before power on, and after the start display is normal, I change to another interface, the display will sometimes be abnormal. I looked at the channel where the 0x20 only allows the camera to be plugged in. If the display is abnormal, soft reset 962 and reconfigure, the display can return to normal.

Hello, 

If you are changing interfaces mid-way, you will need to stop forwarding on the CSI-2 output port. You can do that in register 0x20.

Thanks,

Yes, it has been set for 0x20. Disable does not plug into the port of the camera. And has checked 0x20, sometimes can display. Sometimes it can't be displayed

Are you setting 0x20 = 0xF0 before you plug in? And then enable again (0x00) once you have plugged in?

If I plug in only one camera, but 964 enables two Rx, does the Mipi of 964 have data output？

Hello, 

You need to enable the receiver on the 964 and the transmitter on the 964 to have data output. If you enable port 0 and 1 receiver on the 964 and you turn on the transmitter, yes you will have data output.

Thanks,

Sally
