# 我是上传到了阿里云的 oss 上，通过 curl 下载，也可以通过其他方式比如 WinSCP 上传到路由器里面
# 如果是通过 curl 下载，此时路由器需要插上 WAN 口连上互联网，可以给 WAN 口接上网线
curl -o u-boot.mbn http://oss-hk4.oss-cn-hongkong.aliyuncs.com/tmp/u-boot.mbn
# 确认文件存在且大小正确，我编译的文件大小是 644624
ls -l /root/u-boot.mbn

# 刷入 u-boot，此步骤需要谨慎，刷错可能导致路由器无法启动，需要确保文件存在且完整
# 如果文件不完整这一步可能会导致路由器无法启动，所以一定要确认文件大小和完整性
