Introduction
The Avnet Multi-Camera FMC module supports up to four (4) high definition camera modules
using MAXIM Integrated’ s GMSL (Gigabit Multimedia Serial Link) technology.
GMSL is widely used in the automotive industry for in-vehicle high speed communication of
video streams. Making use of low-cost coax cable up to 15 meters in length, GMSL meets
the most stringent electromagnetic compatibility (EMC) requirements of the automotive
industry.
The provided linux-based reference designs support the ON Semiconductor MARS (Modular
Automotive Reference System) based camera modules, including the MAXIM Integrated
MAX96705 GMSL Serializer board and the ON Semiconductor AR0231AT image sensor board.
The AR0231AT image sensor is an automotive-grade image sensor which uses the latest 3.0
micron Back Side Illuminated (BSI) pixel with ON Semiconductor’s DR-Pix™ technology, which
offers dual conversion gain for improved performance under all lighting conditions. It includes
LED Flicker Mitigation (LFM), and achieves 120dB of High-Dynamic Range with 4-exposure
HDR.
The Multi-Camera FMC Module is available in two options:
-FMC module only (without any cable or cameras)
-Quad AR0231AT Camera FMC bundle (including cable and four cameras)
The Quad AR0231AT Camera FMC Bundle includes the Multi-Camera FMC module, a cable
assembly, as well as four AR0231AT camera modules with GMSL serialization.
The Quad AR0231AT Camera FMC Bundle is meant to be used with Xilinx Zynq-UltraScale+
FMC carriers, including the ZCU102, the ZCU104, as well as the Avnet UltraZed EV SOM +
Carrier. The Quad Camera FMC Bundle is fully integrated to the Xilinx reVISION stack,
including SDSoC platforms and design examples.

Running the Getting Started design
Setup the ZCU102 or ZCU104 hardware as follows:
1. Connect the FMC-MULTICAM4 FMC module to the FMC connector (J5 for HPC0 FMC on ZCU102,
J5 for LPC FMC on ZCU104)
2. Attach the four AR0231AT camera modules to their respective MAX96705 Serializer modules,
and connect to the FMC-MULTICAM4 FMC module with the cable assembly
3. Connect the power supply to the 12V connector (J52 on ZCU102, J52 on ZCU104)
4. Connect the HDMI display with an HDMI cable to the top connector of dual HDMI connector (P7
on ZCU102, P7 on ZCU104)
5. Connect a micro-USB cable to the USB-UART connector (J83 on ZCU102, J164 on ZCU104)
Use the following settings for your terminal emulator:
Baud Rate: 115200
Data: 8 bit
Parity: None
Stop: 1 bit
Flow Control: None
6. Insert SD card (FAT formatted) with pre-built image copied from one of the following
directories:
ZCU102 : sd_card/zcu102_rv_mc4_filter2d_optflow
ZCU104 : sd_card/zcu104_rv_mc4_filter2d_optflow
7. Set boot mode to SD card
ZCU102 : SW6[4:1]: off,off,off, on
ZCU104 : SW6[4:1]: off,off,off, on
8. Turn on the power switch (SW1 on ZCU102, SW1 on ZCU104)
Page 6
Once linux has finished booting, you should see the linux prompt on the serial console:
…
Setting console loglevel to 0 ...
root@xilinx:~# cd /media/card
root@xilinx:/media/card# ./gstfilter2d_optflow.sh
9. Change the active directory to the sd card with the following command : cd /media/card
10. Execute the design with the following command : ./gstfilter2d_optflow.sh
You should observe the live captures from the four cameras on the 4K monitor.
the top-left quadrant is running the “Optical Flow” accelerator, indicating movement in the scene
the bottom-right quadrant is running the “Filter 2D” accelerator, enhancing the edges in the scene
the other two quadrants are running a passthrough
For more details on this design, including instructions on how to modify the gstreamer pipelines
and how to re-build the design, please refer to the “FMC-MULTI-CAM4 reVISION 2018.2 Tutorial”,
available on-line.
