20251224给飞凌OK3588-C开发板适配Rockchip原厂的Android14系统时解决dwhdmi-rockchip fdea0000.hdmi: i2c read time out!
2025/12/24 21:07

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！
