下载树莓派64位系统，我不要桌面所以选择了lite
https://downloads.raspberrypi.org/raspios_lite_arm64/images/raspios_lite_arm64-2020-08-24/2020-08-20-raspios-buster-arm64-lite.zip
用USB Image Tool将镜像写入TF卡（Win32DiskImager只是个垃圾）
用法很简单：插入tf卡，在USB Image Tool左侧选好盘，右侧使用“Restore”将raspios-buster-arm64-lite.img镜像写入tf卡即可。
写入完成后，在资源管理器里会多出一个boot盘符，在boot分区下新建一个空文件，名为ssh，就可以给树莓派开启SSH服务，适合没屏幕操作。
在boot分区下新建wpa_supplicant.conf文件，并写入无线的相关配置。可以同时配置多个无线网络。

由于树莓派并没有传统意义上的BIOS, 所以现在各种系统配置参数通常被存在”config.txt”这个文本文件中.
树莓派的config.txt文件会在ARM内核初始化之前被GPU读取.
这个文件存在引导分区上的.对于Linux, 路径通常是/boot/config.txt, 如果是Windows (或者OS X) 它会被识别为SD卡中可访问部分的一个普通文件.
如果想要编辑配置文件, 请查看介绍编辑树莓派配置文件.
你可以使用下列命令去获取当前激活的设置:
- 列出指定的配置参数.
- 例如: vcgencmd get_config arm_freq
vcgencmd get_config
- 列出所有已设置的整形配置参数(非零)
vcgencmd get_config int
- 列出所有已设置的字符型配置参数(非零)
vcgencmd get_config str

EDIT : After writing this blog post I’ve started a 64-bit OS for the Raspberry Pi 3, based on Debian. You can find it here.
The Raspberry Pi 3 ships with a Broadcom BCM2837 64bit ARMv8 quad core Cortex A53 processor, which is a 64-bit CPU. If you own one of these, running the following command might surprise you :
> uname -a
Linux raspberrypi 4.4.34-v7+ #930 SMP Wed Nov 23 15:20:41 GMT 2016 armv7l GNU/Linux
Yes, this is a 32-bit kernel. The reason for this is that the Raspberry Pi foundation doesn’t yet provides a 64-bit version of Raspbian, the official OS for Raspberry Pi. It is however possible to build one, thanks to the various patches sent by Electron752.
The Raspberry Pi foundation maintains their own fork of the Linux Kernel which is especially tailored for their devices, while upstream gets merged regularly.
