rk3288-reload在ubuntu/linux下适配DVP接口摄像头驱动问题
本帖最后由 CallMeBroYang 于 2016-8-11 19:50 编辑问题：
接上官方的DVP接口的s5k4ecgx摄像头，上电开机，/dev/下找不到video设备。
这里要发下牢骚：官方什么时候可以出ubuntu/linux下直接支持rk3288 dvp接口摄像头的内核，也省得每个人都花时间做适配。
用的ubuntu镜像版本：FireFly-RK3288-Reload_Ubuntu14.04_201603111814
已进行操作如下：
1、
从https://bitbucket.org/T-Firefly/firenow-lollipop/commits/branch/Firefly-RK3288上下载 android5.1 sdk 最新的内核
git pull bitbucket Firefly-RK3288:Firefly-RK3288
make firefly-rk3288-reload-linux_defconfig
make menuconfig；加上cif选项
2、
从fireprime的内核中，把 ./drivers/media/video/s5k4ec.c，复制过来并修改修改Makefile
参照fireprime的内核，修改./include/media/v4l2-chip-ident.h，添加相关宏
参照fireprime的内核，修改./arch/arm/mach-rockchip/rk_camera.c
在./arch/arm/boot/dts下修改rk3288-cif-sensor.dts，添加
14 s5k4ec{
15 status = "okay";
16 is_front = <0>;
17 //rockchip,power_pmu_name1 = "rk818_ldo4";/*cif 2.8v */
18 //rockchip,power_pmu_voltage1 = <2800000>;
19 //rockchip,power_pmu_name2 = "rk818_ldo8";/* cif 1.8v */
20 //rockchip,power_pmu_voltage2 = <1800000>;

3、
make -j8 firefly-rk3288-reload-linux.img
从官方镜像的linux-boot.img提取initrd.img，并与新编译的kernel压缩
mkbootimg --kernel arch/arm/boot/zImage --ramdisk initrd.img -o kernel-boot.img
4、
kernel-boot.img下载到boot分区，resource.img下载到resource分区，
开机后进入系统，还是找不到video设备

请问还需要修改什么地方，
才能让FireFly-RK3288-Reload在ubuntu/linux可以支持DVP接口的s5k4ecgx摄像头？
请问楼主解决问题没有，我也是遇到此问题，我这边是安卓环境，配置完并没有发现 dev下有新设备的出现 linux底下的dvp接口可以参考这个
http://developer.t-firefly.com/forum.php?mod=viewthread&tid=9803&page=1#pid21086 请问楼主解决了没我用的是3128能在dev下面找打设备节点，但是通过V4L2读不到数据啊 carter123456 发表于 2017-8-31 19:08

这个好像要用gst吧
