mtk camera 移植步驟:
1, kernel層驅動**檔案新增
/mediatek/custom/doov92_wet_tdd/kernel/imgsensor/下新增imx179_mipi_raw_
2lane/ 目錄如下:
imx179_mipi_raw_2lane
- imx179mipiraw_camera_sensor_para_2lane.h
- imx179mipiraw_cameracustomized_2lane.h
- imx179mipiraw_sensor_2lane.c
- imx179mipiraw_sensor_2lane.h
看了一下, 基本上所有的驅動檔案都是這樣的格式.
2, hal層效果引數檔案新增
/mediatek/custom/mt6592/hal/imgsensor/下新增imx179_mipi_raw_2lane目錄,該目錄list如下:
imx179_mipi_raw_2lane
- camera_ae_plinetable_imx179raw_2lane.h
- camera_calibration_cam_cal_2lane.cpp
- camera_flicker_para_imx179raw_2lane.cpp
- camera_info_imx179raw_2lane.h
- camera_isp_lsc_imx179raw_2lane.h
- camera_isp_pca_imx179raw_2lane.h
- camera_isp_regs_imx179raw_2lane.h
- camera_tsf_data_imx179raw_2lane.h
- camera_tsf_para_imx179raw_2lane.h
- camera_tuning_para_imx179raw_2lane.cpp
- config.ftbl.imx179_mipi_raw_2lane.h
根據具體的sensor, 檔案會有所增減.
3, 驅動結構新增
./mediatek/custom/common/kernel/imgsensor/src/kd_sensorlist.h:
1)uint32 imx179_mipi_raw_2lane_sensorinit(psensor_function_struct *pffunc);
2) acdk_kd_sensor_init_function_struct kdsensorlist[max_num_of_
support_sensor+1] = ,
#endif
...... }
4, 定義id和drv name
./mediatek/custom/common/kernel/imgsensor/inc/kd_imgsensor.h:
#define imx179_sensor_2lane_id 0x0179
#define sensor_drvname_imx179_mipi_raw "imx179mipiraw_2lane"
5, hal層id與drv name的銜接
./mediatek/custom/common/hal/imgsensor/src/sensorlist.cpp
msdk_sensor_init_function_struct sensorlist =
6, camera sensor巨集配置
/mediatek/config/doov92_wet_tdd/projectconfig.mk ==配置
custom_hal_imgsensor=imx135_mipi_raw imx179_mipi_raw_2lane
custom_hal_sub_imgsensor=imx179_mipi_raw_2lane
custom_kernel_imgsensor=imx135_mipi_raw imx179_mipi_raw_2lane
custom_kernel_sub_imgsensor=imx179_mipi_raw_2lane
7,時序配置
./mediatek/custom/doov92_wet_tdd/kernel/camera/camera/kd_camera_hw.c
else if (currsensorname && (0 == strcmp(currsensorname,"imx179mipiraw_2lane")))
分別配置上電/下電. 原理圖上的pin腳收集如下.
main sensor 控制腳:
cmrst_main
cmpdn_main
vcam_af
af_en
vcamd
vcama
vcamio
scl sda
cmmclk
mipi-rdp0 mipi-rdn0
mipi-rdp1 mipi-rdn1
mipi-rdp2 mipi-rdn2
mipi-rdp3 mipi-rdn3
mipi-rcp mipi-rcn
f-led+
f-led1-
f-led2-
8,camera預覽/拍照儲存**的方向改變
./mediatek/custom/doov92_wet_tdd/hal/imgsensor/src/cfg_setting_imgsensor.cpp //改的是這個
sensororientation_t const&
getsensororientation() ;
return inst; }
