NVIDIA JetPack4.2.2 新版本系统上修改Jetson-TX2配置为配置3
简述 NVIDIA Jetson 的系统版本升级后它的配置方式和驱动等都发生了变化，若是想修改默认配置为配置3，就不能按照JetPack4之前的版本来修改了，在这里为各位分享我在新版本系统上修改配置3的方法。 配置3：使能2个USB3.0和3个PCIe
设置步骤
修改ODMDATA值，将文件p2771-0000.conf.common中的ODMDATA修改为0x6090000 .

以上修改完成，重新将内核代码编译后，再将设备树和镜像烧录到TX2中。
sudo ./flash.sh -r -K kernel/Image -d kernel/dtb/tegra186-quill-p3310-1000-c03-00-base.dtb -o 0x6090000 p2771-0000.conf.common jetson-tx2 mmcblk0p1
测试验证
由于设计的PCIe是连接的百兆以太网网卡，所以在系统网络设置里会看到三个外扩的可用的以太网（电路设计的是外扩3个），连上网线测试可以上网。2个USB都可以接鼠标键盘U盘等设备。
