IMX664 Sync feature

Richa

We are designing one carrier board and wanted to use Camera module MSU-M0186-1-09.

We have noticed that the pinout lists Sensor Sync Signal (21st Pin). Could you please confirm if this is FSYNC pin ?

More on this, we wanted to validate camera synchronicity of 2 cameras. Could you please tell us this Module is in Master mode or Slave Mode ? These modes are Software configurable ?

The IMX664 camera does have a sync input, but we are currently not enabling it in the camera driver.

The sync signal is typically driven by VOXL2 in majority of our use cases and we currently only synchronize the tracking cameras (AR0144).

If IMX664 outputs a sync signal while voxl2 is also outputting that signal, there would be a gpio contention. It is possible to disable voxl2 sync line so that it is not driven.

If you had your own adapter board (or M0173 ?) and wanted to use two IMX664 cameras in master / slave mode, assuming no contention on the sync line, there would need to be some modifications in the camera driver (they could be trivial, but we have not tested it yet on IMX664, but can look into it).

Can you please describe your use case a bit more (specifically, are you going to use our adapter, like M0173) or designing your own adapter that will connect the cameras to VOXL2?

We are designing our custom adapter board which will have mating connector DF56C-26S-0.3V(51) on board to connect MSU-M0186-1-09 camera module.

And we are planning to test synchronicity with other camera. So just wanted to confirm master or slave mode is configured from firmware or is there any dependency on hardware is well for this configuration.
let me know if more details are needed.

@Richa . thanks for the details, got it it.

I will need to test the master / slave mode. Is your plan to have one IMX664 generate the sync signal (master) and the other(s) IMX664 being slaves? or all slaves?

I should be able to give it a quick test this week. The change would involve setting several additional registers in the camera configuration, which would mean a change in the sensormodule driver for the camera. we can figure this out after i verify the functionality.
