使用的iCore-3588Q和AIO-3588Q的底板，没有wifi模块的时候系统无法启动，Debug接口停在了下面内容就不再输出（详细的打印见附件）：

我们的底板有 wifi 模块

板蓝根

如果是你自己的底板，或者把wifi去掉了，请自行修改 dts 关闭 pcie 测试一下

在启动过程中，uboot没办法打断，所以就只能是使用固件升级的方式修改dts，但是wiki里面没有告诉怎么才能把生成的dts打包到单一的固件img里面，所以不知道该怎么做。

另外，按照wiki里面的描述可以使用usb线缆单独的升级dtb文件，但是我用wiki里面说的RKDevTool工具根本看不到“Found One LOADER Device”，所以也没办法单独升级dtb文件（驱动里面可以看到Rockusb Device）。所以不知道该怎么方便的升级dtb呢？
