基于全志a31s的camrea驱动调试（gc2145型号）

栏目：综合技术时间：2015-02-06 09:00:45

运行命令make ARCH = menuconfig进入device drivers--->Multimedia support--->配置以下

把GC2145的驱动文件gc2145.c放在licheelinux⑶.3driversmediavideosunxi-vfedevice下并在其目录下的Makefike文件添加

obj-$(CONFIG_CSI_VFE) += cci.o

......

obj-m += gc2145.o

修改lichee oolspackchipssun6iconfigsandroidmars-ml220sys_config.fex文件中内容以下
