双MAX9296-GMSL2摄像头接入扩展板

主要特征

发货清单

总体结构

（随版本更新，上图会略有差异， 请以板上丝印为准）

基本参数

安装与连接

注意，必须使用合适的支撑柱及螺丝进行安装，否则可能影响稳定性

SK板安装

如图所示， 扩展板与主板之间使用3颗直径2.5mm， 高5mm 的铜柱支撑。

EVM板安装

如图所示， 扩展板与主板之间使用3颗直径2.5mm， 高11mm 的铜柱支撑。

连接电源

必须使用主板官方指定的电源， 并保证足够的功率， 否则运行过程中可能会非预期重启。

连接GMSL相机

还没有GMSL相机？可以试试揖越的GMSL视频输入设备：gmsl2摄像头

快速上手

请参数上述步骤连接主板与扩展卡。必须保持二者的连接可靠。不可靠连接可能导致工作不正常甚至损坏硬件。

附带的SD卡，预设置了一些出厂适配完成的摄像头/视频源，分别为：

  • 森云 IMX390
  • HDMI转GMSL2 视频注入 （本公司产品）

其它测试使用相机，可以参考[] 请注意相机电压与扩展板供电电压是否匹配

插入附带的SD卡。目前仅提供SK板的测试用SD卡。此卡官方SK板镜像相比，做了如下修改：

  • 显示改为由R5控制
  • 视频输入使用RTOS，OPENVX框架，由R5控制
  • 神经网络运行，openvx框架， OSRT支持受限

连接显示器、网线， 串口线。使用HDMI连接显示器 （默认使用HDMI显示），网线主要用于调试。

插上供电口USB （sk板），确认扩展板指示灯显示正常。需要注意：

  • Type-C USB的供电功率是否充足，推荐使用笔记本电源
  • 摄像头GMSL的POC电源跳线是否接上

（各个Channel的供电由GPIO控制，可不用跳线）

上电进入terminal,需运行以下脚本，建立工作环境。

cd /opt/vision_apps
source ./vision_apps_init.sh
./run_app_single_cam.sh

注意，注意，如果摄像头连接的是CH1，需要运行针对CSIRX2_1编译的程序。 

./run_app_single_cam_ch1.sh

正常运行时的log [采购后可查看]

其它注意事项

软件开发环境建立

使用EVM板

可以直接使用，具体使用方法，请参考官方文档。

使用SK板

需要对SDK进行一些修改，请参考文档 利用Starter-Kit开发板开发RTOS应用

解串的地址

MAX9296的默认地址

默认工作模式及修改

默认工作模式

CH0, CH1的MAX9296的默认工作模式均为：GMSL2, 6Gbps.

通过硬件跳线修改默认工作模式

Max9296 支持GMSL1/GMSL2, 3G/6G， coax/stp， i2c/uart 等在上电时通过分压电阻进行配置。这些配置不建议修改，但如需修改，推荐使用I2C修改寄存器的方式修改。如果确需要修改硬件，参考下图：

电阻的选择请参考 美信 数据手册。

通过软件I2C配置工作模式

使用I2C修改GMSL模式，参考如下代码，可以在不变更硬件的情况下，在GMSL1/GMSL2模式下切换。 具体操作，请参考：软件修改MAX9296的模式及速率 。

配置帧同步信号

使用多个摄像头需要进行同步。当MAX9296工作于GMSL1，或GMSL2模式时，其同步配置是不同的。 具体的操作及配置，请参考：MAX9296的多相机FSYNC配置.
