-----------------------------------------------------------------------------------------------------------------
修改sample 模块下面的Makefile.param 进行修改
SENSOR_TYPE ?= SONY_IMX178_LVDS_1080P_30FPS
改为
#SENSOR_TYPE ?= SONY_IMX178_LVDS_1080P_30FPS

#SENSOR_TYPE ?= OMNIVISION_OV4689_MIPI_1080P_30FPS
改为：
SENSOR_TYPE ?= OMNIVISION_OV4689_MIPI_1080P_30FPS

..\mpp\sample\common\sample_comm_vi.c 修改如下：
combo_dev_attr_t MIPI_4lane_SENSOR_OV4689_12BIT_ATTR =
{
.input_mode = INPUT_MODE_MIPI,
{

.mipi_attr =
{
RAW_DATA_12BIT,
{1, 0, 2, 3, -1, -1, -1, -1}
}
}
};

改为

combo_dev_attr_t MIPI_4lane_SENSOR_OV4689_12BIT_ATTR =
{
.input_mode = INPUT_MODE_MIPI,
{

.mipi_attr =
{
RAW_DATA_12BIT,
{0, 1, 2, 3, -1, -1, -1, -1}
}
}
};

解释，就是把 img_size 变成了1 而wdr_mode 设置为0 禁用。
typedef struct
{
img_size_t img_size; /* oringnal sensor input image size */
wdr_mode_e wdr_mode; /* WDR mode */
lvds_sync_mode_e sync_mode; /* sync mode: SOL, SAV */
raw_data_type_e raw_data_type; /* raw data type: 8/10/12/14 bit */
lvds_bit_endian data_endian; /* data endian: little/big */
lvds_bit_endian sync_code_endian; /* sync code endian: little/big */
short lane_id[LVDS_LANE_NUM]; /* lane_id: -1 - disable */

/* each vc has 4 params, sync_code[i]:
sync_mode is SYNC_MODE_SOL: SOF, EOF, SOL, EOL
sync_mode is SYNC_MODE_SAV: invalid sav, invalid eav, valid sav, valid eav */
unsigned short sync_code[LVDS_LANE_NUM][WDR_VC_NUM][SYNC_CODE_NUM];
} lvds_dev_attr_t;

重新运行，成功出现图像。

二。调试bv_test 模块
1.
修改sensor Type，打开bv_test 上一级目录中的Makefile.param：
SENSOR_TYPE ?= SONY_IMX178_LVDS_1080P_30FPS
改为
#SENSOR_TYPE ?= SONY_IMX178_LVDS_1080P_30FPS

#SENSOR_TYPE ?= OMNIVISION_OV4689_MIPI_1080P_30FPS
改为：
SENSOR_TYPE ?= OMNIVISION_OV4689_MIPI_1080P_30FPS

2.
修改W:\mpp\project\bv_test\bv_hal.c
PIC_SIZE_E enPicSize = PIC_HD1080;

HI_MPI_VB_Init 初始化失败:
修改：缓存池个数，修改为4个
stVbConf.astCommPool[0].u32BlkCnt = u32ViChnCnt * 4;

[SAMPLE_COMM_VPSS_StartGroup]-88: HI_MPI_VPSS_CreateGrp failed with 0xa0078010!
[bv_hal_start]-107: start VPSS GROUP failed!

3.
Error：
   mmz_userdev:ioctl_mmb_alloc: hil_mmb_alloc(, 921600, 0x00000000, 0, ) failed!
   System alloc mmz memory failed!
   [SAMPLE_COMM_IVE_CreateImage]-894: Mmz Alloc fail,Error(0xffffffff)

+#define MAX_GRAY_IMG 10

4 .
W:\mpp\project\common\sample_comm_vi.c 修改如下：
combo_dev_attr_t MIPI_4lane_SENSOR_OV4689_12BIT_ATTR =
{
.input_mode = INPUT_MODE_MIPI,
{

.mipi_attr =
{
RAW_DATA_12BIT,
{1, 0, 2, 3, -1, -1, -1, -1}
}
}
};

改为

combo_dev_attr_t MIPI_4lane_SENSOR_OV4689_12BIT_ATTR =
{
.input_mode = INPUT_MODE_MIPI,
{

.mipi_attr =
{
RAW_DATA_12BIT,
{0, 1, 2, 3, -1, -1, -1, -1}
}
}
};

============================================================================
如果修改为 ov4689 4M

打开 SENSOR_TYPE ?= OMNIVISION_OV4689_MIPI_4M_30FPS
修改W:\mpp\project\bv_test\bv_hal.c
PIC_SIZE_E enPicSize = PIC_2592x1520;
stVbConf.astCommPool[0].u32BlkCnt = u32ViChnCnt * 2;

bv_core.c
#define MAX_GRAY_IMG 4

W:\mpp\project\common\sample_comm_vi.c 修改如下：
combo_dev_attr_t MIPI_4lane_SENSOR_OV4689_12BIT_ATTR =
{
.input_mode = INPUT_MODE_MIPI,
{

.mipi_attr =
{
RAW_DATA_12BIT,
{1, 0, 2, 3, -1, -1, -1, -1}
}
}
};

改为

combo_dev_attr_t MIPI_4lane_SENSOR_OV4689_12BIT_ATTR =
{
.input_mode = INPUT_MODE_MIPI,
{

.mipi_attr =
{
RAW_DATA_12BIT,
{0, 1, 2, 3, -1, -1, -1, -1}
}
}
};
