20251224给飞凌OK3588-C开发板适配Rockchip原厂的Buildroot【linux-6.1】系统时确认ssh服务【内置dropbear】

2025/12/24 10:25

缘起：给飞凌OK3588-C开发板适配Rockchip原厂的Buildroot【linux-6.1】后，需要配置ssh。

驱动调试的时候DEBUG口就足够了。最多再打开一个USB接口的adb功能。【有些时候需要多一个口^_】

但是产品给客户暴露的借口就是TF卡的卡槽和以太网接口了！【应用工程师需要的ssh功能】

想实测一下TF卡的读写速度。

4线USB2.0通过adb直接拿到电脑上的速度是：31.3 MB/s

写入TF卡的速度略微低于31.3 MB/s【大概为25.56MB/s】

需要实测开发板丝印ETH1芯片RTL8211F-CG的网速。

通过ifconfig确认为eth0。

需要使用ov5645的驱动框架来适配LVDS接口的105机芯。

按照以前的经验，首先关闭I2C的读写！

结果，肯定会出现某些地方遗漏的，只能通过编译器来检查问题了！

当你把荣品RD-RK3588开发板重新适配一把，就相当于从头做了一个项目：【荣品RD-RK3588开发板】。

当然，开发板的功能都是好的，你免除了调试的过程，也就没有解决相关硬件出错的经验/机会了！

1、都去找DeepSeek咨询配置openSSH的方法了，没有想到 Rockchip原厂的Buildroot【linux-6.1】系统默认集成轻量级的ssh服务器dropbear。

就算你设置密码了，winSCP也是链接不进来的。

必须退出winSCP之后，再次链接了！^_

RK3588 Buildroot SSH配置指南

RK3588的buildroot，默认自带SSH服务器吗？用户名？密码？

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

密码设置方式：

首次启动后设置：

bash

通过串口登录后设置

passwd
