RK3588编译编译一下recovery，需要把buildroot源码编译一遍。遇到好几个文件都下载失败，如下所示
pm-utils 1.4.1这个包下载失败，下载地址http://pm-utils.freedesktop.org/releases
解决办法，换个网络用windows浏览器下载后，放到dl目录，这一步错误就过了
====Start build rockchip_rk3588_recovery====
2025-04-17T15:45:22 >>> pm-utils 1.4.1 ....
在下载squashfs包是一直卡住，下载不成功，没办法继续编译了
====Start build rockchip_rk3588_recovery====
2025-04-17T16:03:10 >>> host-squashfs 3de1687d7432ea9b302c2db9521996f506c140a3 Downloading
^CCommand terminated by signal 2下载后，在dl目录下有这么个文件。如果用pm-utils 1.4.1问题同样的方法，只能下载squashfs-tools-4.6.tar.gz或者squashfs-tools-4.6.1.tar.gz。编译仍然过不了，继续卡住
查看packet目录下的Config.in文件，将SQUASHFS_SITE_METHOD从git修改成web，然后解决，在dl目录下看到的是图中的文件名
squashfs-3de1687d7432ea9b302c2db9521996f506c140a3.tar.gz
SQUASHFS_VERSION = 3de1687d7432ea9b302c2db9521996f506c140a3
