Allied Vision CSI-2 Adapter Board for Nvidia Jetson TX2 Xavier Dev Kit

nvidia_TX2_Xavier_adapter nvidia_TX2_Xavier_adapter

This repository contains open hardware design files for an adapter board supporting the Allied Vision Alvium CSI-2 camera pinout to NVidias TX2 and Xavier Development kit CSI-2 connector compatible devices, created by Allied Vision. The board allows the user to interface with two Alvium MIPI CSI-2 compatible cameras over a Flexible Flat Cable (FFC) connector.

You can also purchase the adapter from Allied Vision or from our distributors.

Getting Started

These instructions will get you a copy of the design files to make your own adapter boards for development and testing purposes. The board can be produced and assembled using the provided design files. Please take a look at the mechanical layers for more information regarding the PCB stackup recommended for fabrication.

See our accessories webpage and the Alvium CSI-2 download webpage for more information.

Prerequisites

  • A running installation of Altium.
  • A PCB producer & PCBA manufacturer or some soldering skills.
  • One of the supported embedded boards :
    • Nvidia Jetson TX2 Developer Kit
    • Nvidia Jetson AGX Xavier Developer Kit
  • One or two supported MIPI CSI-2 FPC cable
    • Allied Vision part numbers #12316, 12317, 12318
  • One or two Allied Vision Alvium CSI-2 camera

Installing

Open the CSI2-TX2-XAVIER_Rev01.PrjPcb project file in your Altium environment.

adapter_nvidia_jetson_tx2_xavier_devkit's Issues

residual voltage on j1/j2 pins 1/3 when trying to use as input gpio

manual says to remove resistors R1 R2 R3 R4 in order to use as GPIO
however after removal whenever adapter board is powered (even if not connected to Jeston) GPIO pins have a constant ~2.5V voltage.
when changing lines to be as output, voltage does drop to 0 , and tests with scope have indicated it works as it should
examples and code from allied vision GitHub repository was used with same results.
cameras work fine with software trigger but with current situation , HW trigger is impossible.
we tried it with several boards and several adapters. does gpio require an additional pullup/pulldown resistor?

this was tested using a JESTON XAVIER with jetpack 4.6.1/4.6.2/5.0.2 (and as mentioned this behavior was observed when adapter was not connected as well)
2 cameras are allvium 1800 c-040m with
it was also observed when only 1 camera was connected with 12318 cables.
please provide example schematic for connecting to external HW trigger
