위와 같이 변경을 합니다.
이제 초기화 값을 변경 해 보겠습니다.
에서
커널 소스에서
“driver/media/video/sr130pc10.h” 파일에서
static unsigned char sr130pc10_init_reg[][2] = {
초기화 값으로 대체합니다.
"drivers/media/video/Kconfig" 파일에서 아래와 같이 추가 합니다.
config VIDEO_SR130PC10
tristate "SR130PC10 Camera Sensor"
depends on I2C && VIDEO_V4L2
---help---
This driver supports CRZ sr130pc10 SoC camera module
“drivers/media/video/Makefile” 파일에서
obj-$(CONFIG_VIDEO_SR130PC10) += sr130pc10.o
추가
그리고, 커널 빌드를 합니다.
./build_kernel mango210_7inch_mrvl8787_5M_android_defconfig
빌드 후
