20251223给飞凌OK3588-C开发板适配Rockchip原厂的Buildroot【linux-6.1】系统时解决给TF卡写入大文件破坏文件系统的问题
2025/12/23 14:05

缘起：给飞凌OK3588-C开发板适配Rockchip原厂的Buildroot【linux-6.1】后，需要适配好TF卡。
看飞凌OK3588-C开发板的Andoid14的SDK是没有适配TF卡的电源使能GPIO口GPIO2C4的。
去飞凌OK3588-C开发板的Linux R4/Buildroot中找到了：TF卡的电源使能GPIO口GPIO2C4的。
去适配好！

想实测一下TF卡的读写速度。
实测写入小文件正常，但是大体积的视频文件写入TF卡之后，插入到WIN10的电脑，直接发现分区都给干没了！
原因待查。初步发现是GPIO口冲突：pin-75 (fe2d0000.mmc) status -22

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20 MB/s】写入之后TF卡分区丢失^_
25.5606790168

缘起：给飞凌OK3588-C开发板适配Rockchip原厂的Buildroot【linux-6.1】后，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！
