20260418给万象奥科的开发板HD-RK3576-PI适配瑞芯微原厂的Buildroot时通过WinScp传送文件【SSH模式】

2026/4/18 19:09

缘起：通过 WinScp 连接 万象奥科的开发板HD-RK3576-PI

1、从WIN10上 通过WinScp传送文件【SSH模式】，大概需要8分37秒钟。

参考速度：6.73MB/S

远低于 25.12MB/s【Ubuntu系统】，有点感觉网卡是100Mbps模式

【Ubuntu系统下】

2、根据dmesg显示的内核信息，确认以太网卡是千兆网卡模式：

3、通过iperf2实测网卡确实工作在千兆网卡模式：实测网速931Mbits/sec

4、可能的原因：RK3576的Buildroot【linux-6.1】系统时确认ssh服务【内置dropbear】。

dropbear只是轻量级的ssh【只保证通，但是不保证好用！】

在拷贝大文件的时候效率明显低于OpenSSH（功能完整）

RK3588 Buildroot SSH配置指南

RK3588的buildroot，默认自带SSH服务器吗？用户名？密码？

2. 如果需要SSH支持，推荐配置：

方法一：使用Dropbear（轻量级）

bash

选择 Dropbear

Target packages → Networking applications → dropbear

可能需要启用以下选项：

- Install dropbear website keys

- Enable scp

方法二：使用OpenSSH（功能完整）

bash

Target packages → Networking applications → openssh

5、从eMMC将大视频拷贝到TF卡上的速度：

root@rk3576-buildroot:~#
root@rk3576-buildroot:~# time(cp test2.mp4 /mnt && sync)

real 1m32.007s

user 0m0.082s

sys 0m15.423s

root@rk3576-buildroot:~#

root@rk3576-buildroot:~#

3859020MB/92s = 41.95MB/s

3859020/92 = 41.945652173913

接近46.49MB/s【Ubuntu系统】

确认md5sum值：

root@rk3576-buildroot:~#
root@rk3576-buildroot:~# md5sum test2.mp4
7813a759d67c74ac411eafa168cbe77f test2.mp4

root@rk3576-buildroot:~#

root@rk3576-buildroot:~# cd /mnt/

root@rk3576-buildroot:/mnt#
