20251217给飞凌OK3588-C开发板适配Rockchip原厂的Buildroot【linux-5.10】后调通ov5645【只能预览】
2025/12/17 10:16
缘起：给飞凌OK3588-C开发板适配Rockchip原厂的Buildroot【linux-5.10】后，调通了OV5645摄像头模块！
出现的问题：
1、颜色严重偏红。由于使用的是taobao淘宝货，非飞凌原厂的摄像头，可能余摄像头有关系。电话问过飞凌的FAE，他们回复：有点红，但是肯定不像你这样整体泛红。
2、预览的时候不能录像。【原因待查】
适配Rockchip原厂的Buildroot【linux-6.1】时，在预览的时候可以同步录像的！

【飞凌魔改的驱动来自/搬运于：OK3588-C_Linux5.10.209+Qt5.15.10_用户资料_R1】
飞凌OK3588-C开发板跑Rockchip原厂的Buildroot【linux-6.1】系统时，适配ETH1接口的网卡。
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！

【原版本的ov5645.c这个驱动程序是打不开摄像头的！虽然瑞芯微Rockchip的Anroid14系统SDK中有ov5645.c这个驱动程序，但是不能用/不完备！】
【需要使用飞凌魔改版本的！】

但是你不能直接整体使用的飞凌Android14的DTS，会出现的问题有：
1、编译问题。dsi0/dsi1参数的问题。
2、处理好编译问题之后，不能进Android14系统的问题。
一般认为是飞凌魔改了Android14的kernel-6.1中的Makefile，使其直接支持linux-5.10【Android13】的DTS。
3、其它未知问题了！
