20240423给飞凌的OK3588-C开发板适配OV13855【绿屏】
2024/4/22 20:29
开发板:飞凌的OK3588-C
OS操作系统:linux R4/Buildroot
【OV13855接到CAM1上,如果要接到CAM2上请修改相关的DTS即可】

OV13850/OV13855摄像头模组适用3399/3568/3588飞凌嵌入式开发板
颜色分类:OV13855自动对焦摄像头
缘起:想调试OV13855很久了!
一直没有找到机会!
【当时想在RK3399平台上搞通OV13850的4K录像,貌似两个都不行!】
发现Orange Pi5是可以支持OV13850和OV13855的!
【并且还可以混搭的!】^_
【Orange Pi5开发板上面的OV13855是好的,还可以4K录像!】
你要找一个32GB的TF卡和一台HDMI显示器,使用
C:\Android镜像烧录工具-SDDiskTool\SDDiskTool_v1.72\SD_Firmware_Tool.exe
刷机:OrangePi5_RK3588S_Android12_v1.0.5.img。
摄像头OV13855的PIN脚定义见附件:OV13855的摄像头资料20240422.zip
对DTS/ov13855.c和Makefile修改参考了Orange Pi5的SDK。
http://www.orangepi.cn/html/hardWare/computerAndMicrocontrollers/service-and-support/Orange-pi-5.html
android源码
修改的文件:OK3588_Linux_fs_ov13855e_20240420_1409.7z
【ov13855.c 必须使用 Orange Pi5的SDK中的,否则只有绿色但是没有 影子!】
