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。

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
密码设置方式：
首次启动后设置：
bash
# 通过串口登录后设置
passwd
