如何查询开发板arm 类型？

在 Linux 系统中，你可以通过以下几个命令来查询 ARM 处理器的信息：

查看处理器架构：

uname -m

复制代码

查看详细的 CPU 信息：

cat /proc/cpuinfo

复制代码

查看系统架构：

arch

复制代码

如果要查看更详细的硬件信息：

lscpu

复制代码

这些命令会显示处理器的架构类型、型号、核心数等信息。对于 ARM 开发板，你通常会看到类似 armv7l、aarch64 这样的架构信息。
这两个命令，怎么一个是64的，一个是32

这种情况通常出现在以下场景：

这种差异可能是因为：

你的系统是 64 位的 ARM 处理器（aarch64）

但系统中安装了 32 位的用户空间程序或库

或者系统配置为优先使用 32 位模式运行应用程序

这种配置在某些情况下是正常的，特别是在需要兼容性的场景下。如果你需要完全使用 64 位环境，可以：

确认系统是否完整安装了 64 位的用户空间程序

检查系统的多架构支持配置

确保使用的软件包都是 64 位版本

你可以使用以下命令进一步确认系统状态：

file /bin/bash

复制代码

这会显示系统默认 shell 是 32 位还是 64 位的。
