首先通过查询，得到Atlas200 I的ID
然后，解压Ascend310B-source，修改Ascend310B-source/dtb/dts/hi1910b/hi1910BL/下的文件hi1910B-asic-M150-B51.dts。，新增并修改内容如下：
同时，修改Ascend310B-source/dtb/dts/hi1910b/hi1910BL/product/hi1910B-pinctrl-M100-B51.dtsi下的，新增并修改内容如下：
修改后，进行编译、导入到Atals200I，生效。最后reboot后，检查：
结果显示如下：
可以看到，uart1没有生效。
请问是哪里出问题呢？应该如何解决呢？
