PCAM adapter with ZCU102


menelik

Question

 I'm trying to use Pcam FMC with a ZCU102. I've looked through this post

so I know there may be a way forward by editing the netlist using post synthesis constraining. Because the I2C switch select lines are grounded on the ZCU102, I can only communicate with CAMA so going to use this as a one camera interface. I've also verified the IO requirements and other architecture requirements. So far, I don't see anything stopping me from using to interface with camera A with a ZCU102. However, I want to use the MIPI D-PHY Xilinx IP but need help with the configuration. Looking through the timing.xdc in the reference project, the data rate appears to be 420Mbps. Is this correct? What are the recommended/correct settings?  Please see screenshot. Any other advice on using this with a ZCU102 is appreciated.  685922747_ScreenShot2020-10-14at1_51_22PM.thumb.png.e3e341659a27da9a75dca961353e8390.png

This does not make sense. U135 on ZCU102 has FMC_HPC0 on channel 0 FMC_HPC1 on channel 1. By addressing U135 on bus I2C1_SDA/SCL you open the right channel to reach the SDA/SCL bus of the FMC Pcam Adapter. Then you address the IC3 I2C switch on the FMC Pcam Adpter to open a channel to camera A,B,C or D.

Depends on how you configure the sensor. If you are using project https://github.com/Digilent/ZedBoard-FMC-Pcam-Adapter-DEMO/blob/174903defd61e3e00feea90fd05c08512dae385f/sdk/appsrc/ZedBoard_FMC_Pcam_Adapter_DEMO/main.cc#L179, then it configures the sensor with OV5640_cfg::mode_t::MODE_1080P_1920_1080_30fps_336M_MIPI, which is https://github.com/Digilent/ZedBoard-FMC-Pcam-Adapter-DEMO/blob/174903defd61e3e00feea90fd05c08512dae385f/sdk/appsrc/ZedBoard_FMC_Pcam_Adapter_DEMO/cam/OV5640.h#L341 so 672 Mbps data rate.
