-如果当前目录下有成套的内核文件，将使用当前目录的内核进行更新（更新需要的 4 个内核文件是 `header-xxx.tar.gz`, `boot-xxx.tar.gz`, `dtb-amlogic-xxx.tar.gz`, `modules-xxx.tar.gz`。其他内核文件不需要，如果同时存在也不影响更新，系统可以准确识别需要的内核文件）。如果当前目录没有内核文件，将从服务器查询并下载同系列的最新内核进行更新。你也可以查询[可选内核](https://github.com/ophub/kernel/tree/main/pub/stable)版本，进行指定版本更新：`armbian-update 5.4.180`。在设备支持的可选内核里可以自由更新，如从 5.4.180 内核更新为 5.10.100 内核。内核更新脚本会在开发中不断更新，可使用此命令同步更新本地的脚本：`wget -O /usr/sbin/armbian-update git.io/armbian-update` 。或者直接使用服务器端最新脚本进行内核更新：`bash <(curl -fsSL git.io/armbian-update) 5.4.180`

-If there is a set of kernel files in the current directory, it will be updated with the kernel in the current directory (The 4 kernel files required for the update are `header-xxx.tar.gz`, `boot-xxx.tar.gz`, `dtb-amlogic-xxx.tar.gz`, `modules-xxx.tar.gz`. Other kernel files are not required. If they exist at the same time, it will not affect the update. The system can accurately identify the required kernel files). If there is no kernel file in the current directory, it will query and download the latest kernel of the same series from the server for update. You can also query the [optional kernel](https://github.com/ophub/kernel/tree/main/pub/stable) version and update the specified version: `armbian-update 5.4.180`. The optional kernel supported by the device can be freely updated, such as from 5.4.180 kernel to 5.10.100 kernel. The kernel update script will be continuously updated during development. You can use this command to update the local script synchronously: `wget -O /usr/sbin/armbian-update git.io/armbian-update` . Or directly use the latest script on the server side to update the kernel: `bash <(curl -fsSL git.io/armbian-update) 5.4.180`

-When the kernel is updated, By default, download from [stable](https://github.com/ophub/kernel/tree/main/pub/stable) kernel version branch, if you download other [version branch](https://github.com/ophub/kernel/tree/main/pub), please specify according to the branch folder name in the `2` parameter, such as `armbian-update 5.7.19 dev` . The mainline u-boot will be installed automatically by default, which has better support for kernels using versions above 5.10. If you choose not to install, please specify it in the `3` input parameter, such as `armbian-update 5.4.180 stable no `
