VEYE MIPI 290/327 for Jetson Nano/zh

English

1 概述

本文讲述怎样讲VEYE-MIPI-290/327 模组接入到英伟达公司的Jetson Nano开发板上。采用的Jetson Nano软件版本为r32.2.1，我们提供了编译好的固件和源代码两种方式来方便用户的使用。

VEYE-MIPI-290/327是星光级内置ISP的摄像头模组，输出为MIPI-CSI2接口UYVY流模式。对于图像效果参数，我们并没有采用V4L2接口实现，而是采用了Shell脚本直接控制摄像头模组。

2 硬件准备及安装

Jetson Nano的CSI2接口与树莓派的兼容，因此Mini Adapter Board与Adapter Board都可以使用。此外，由于VEYE-MIPI-290/327的功耗比较大，需要额外的5V供电。

3 软件系统安装及准备

Jetson Nano的系统安装及使用请参考官方文档：get-started-jetson-nano-devkit. 详细的开发资料请参考官方文档：https://docs.nvidia.com/jetson/archives/l4t-archived/l4t-321/index.html

3.1 开发环境准备

• Host PC which runs Ubuntu 16.04 (64-bit).  

• NVIDIA® provided L4T release and corresponding sample rootfs for Jetson Nano™ development kit.  

• A kernel image , device tree blob (DTB) file and module drivers for the VEYE-MIPI-290/327 camera. The release package contains a kernel binary (Image),DTB files and module drivers, which you can download and rebuild from source.

• A jumper pin connected across J48 button header to enable DC power.
• A USB cable (micro USB port) to plug into the recovery port of the Jetson Nano™
• development kit.
• Power cable (5V-4A) to power the Jetson Nano™ board.
• Micro SD card must be connected to the J501 slot.
• A jumper pin must be connected to the pin 3 and pin 4 of J40 button header.  

4 系统软件更新

4.1 准备工作

• 编译工具链

请参考这个链接安装编译工具链。

• L4T源码和Rootfs

可以通过SDK Manager或者直接下载两种方式来获得源码。具体参考官方文档，此处不再赘述。

• 配置开发环境

以下步骤假设SDK安装目录为<TOPDIR>，源代码在$L4T_DIR/sources目录。
export TOP_DIR=<absolute path to top dir;in my case is /home/xumm/nvidia/nvidia_sdk/JetPack_4.2.2_Linux_GA_P3448/>

export L4T_DIR=$TOP_DIR/Linux_for_Tegra

export LDK_ROOTFS_DIR=$TOP_DIR/Linux_for_Tegra/rootfs

export ARCH=arm64

export CROSS_COMPILE=aarch64-linux-gnu-

export CROSS32CC=arm-linux-gnueabihf-gcc

mkdir -p $L4T_DIR/sources/kernel/out_kernel

export TEGRA_KERNEL_OUT=$L4T_DIR/sources/kernel/out_kernel

export KERNEL_PATH=$L4T_DIR/sources/kernel/out_kernel
