hi3519多sensor设置说明
mipi接口模式与设备号
3519总共有12-lane输入,从手册上看支持12lane,8lane+4lane,4lane+4x2lane
SDK中从mipi_rx.c文件mipi_print_lane_divide_mode函数可以区分mipi模式
static const char *mipi_print_lane_divide_mode(lane_divide_mode_t mode)
switch (mode)
case LANE_DIVIDE_MODE_0:
return "12";
case LANE_DIVIDE_MODE_1:
return "8+4";
case LANE_DIVIDE_MODE_2:
return "8+2+2";
case LANE_DIVIDE_MODE_3:
return "4+8";
case LANE_DIVIDE_MODE_4:
return "4+4+4";
case LANE_DIVIDE_MODE_5:
return "4+4+2+2";
case LANE_DIVIDE_MODE_6:
return "4+2+2+2+2";
default:
break;
return "N/A";
LANE_DIVIDE_MODE_4对应的是3个4lane接口
LANE_DIVIDE_MODE_6对应的是5个4lane+2lane+2lane+2lane+2lane接口
目前我只测试了LANE_DIVIDE_MODE_6模式的1个4lane sensor和LANE_DIVIDE_MODE_4模式的2个4lane sensor
由于最开始不了解，默认代码里一个sensor时是使用的LANE_DIVIDE_MODE_6模式
然后通过mipi_rx_hal.c中mipi_rx_drv_is_lane_valid函数可以确认每个通道对应的设备号
int mipi_rx_drv_is_lane_valid(combo_dev_t devno, short lane_id, lane_divide_mode_t mode)
int lane_valid = 0;
switch (mode)
case LANE_DIVIDE_MODE_0:
if (devno == 0)
if (0 <= lane_id && lane_id <= 11)
lane_valid = 1;
break;
case LANE_DIVIDE_MODE_1:
if (devno == 0)
if (0 <= lane_id && lane_id <= 7)
lane_valid = 1;
else if (devno == 3)
if (8 <= lane_id && lane_id <= 11)
lane_valid = 1;
break;
case LANE_DIVIDE_MODE_2:
if (devno == 0)
if (0 <= lane_id && lane_id <= 7)
lane_valid = 1;
else if (devno == 3)
if (lane_id == 8 || lane_id == 10)
lane_valid = 1;
else if (devno == 4)
if (lane_id == 9 || lane_id == 11)
lane_valid = 1;
break;
case LANE_DIVIDE_MODE_3:
if (devno == 0)
if (0 <= lane_id && lane_id <= 3)
lane_valid = 1;
else if (devno == 1)
if (4 <= lane_id && lane_id <= 11)
lane_valid = 1;
break;
case LANE_DIVIDE_MODE_4:
if (devno == 0)
if (0 <= lane_id && lane_id <= 3)
lane_valid = 1;
else if (devno == 1)
if (4 <= lane_id && lane_id <= 7)
lane_valid = 1;
else if (devno == 3)
if (8 <= lane_id && lane_id <= 11)
lane_valid = 1;
break;
case LANE_DIVIDE_MODE_5:
if (devno == 0)
if (0 <= lane_id && lane_id <= 3)
lane_valid = 1;
else if (devno == 1)
if (4 <= lane_id && lane_id <= 7)
lane_valid = 1;
else if (devno == 3)
if (lane_id == 8 || lane_id == 10)
lane_valid = 1;
else if (devno == 4)
if (lane_id == 9 || lane_id == 11)
lane_valid = 1;
break;
case LANE_DIVIDE_MODE_6:
if (devno == 0)
if (0 <= lane_id && lane_id <= 3)
lane_valid = 1;
else if (devno == 1)
if (lane_id == 4 || lane_id == 5)
lane_valid = 1;
else if (devno == 2)
if (lane_id == 6 || lane_id == 7)
lane_valid = 1;
else if (devno == 3)
if (lane_id == 8 || lane_id == 9)
lane_valid = 1;
else if (devno == 4)
if (lane_id == 10 || lane_id == 11)
lane_valid = 1;
break;
default:
break;
return lane_valid;
最终模式设置是在sample_comm_vi.c中SAMPLE_COMM_VI_StartMIPI函数
会调用SAMPLE_COMM_VI_SetMipiHsMode(LANE_DIVIDE_MODE_4)设置mipi模式
接口配置主要代码
sample_comm_vi.c文件SAMPLE_COMM_VI_GetComboAttrBySns函数
根据上面设置的mipi模式对各通道参数进行设置，以LANE_DIVIDE_MODE_4模式进行说明
combo_dev_attr_t MIPI_4lane_CHN0 =
.devno = 0,
.input_mode = INPUT_MODE_MIPI,
.data_rate = MIPI_DATA_RATE_X1,
.img_rect = 0, 0, 1920, 1080,
.mipi_attr =
DATA_TYPE_RAW_10BIT,
HI_MIPI_WDR_MODE_NONE,
0, 1, 2, 3, -1, -1, -1, -1
;
combo_dev_attr_t MIPI_4lane_CHN1 =
.devno = 1,
.input_mode = INPUT_MODE_MIPI,
.data_rate = MIPI_DATA_RATE_X1,
.img_rect = 0, 0, 1920, 1080,
.mipi_attr =
DATA_TYPE_RAW_10BIT,
HI_MIPI_WDR_MODE_NONE,
4, 5, 6, 7, -1, -1, -1, -1
;
combo_dev_attr_t MIPI_4lane_CHN2 =
.devno = 3,
.input_mode = INPUT_MODE_MIPI,
.data_rate = MIPI_DATA_RATE_X1,
.img_rect = 0, 0, 1920, 1080,
.mipi_attr =
DATA_TYPE_RAW_10BIT,
HI_MIPI_WDR_MODE_NONE,
8, 9, 10, 11, -1, -1, -1, -1
;
分别对应硬件接口MIPI0,MIPI1,MIPI2
最后面那个devno为3具体是根据mipi_rx_hal.c中mipi_rx_drv_is_lane_valid函数LANE_DIVIDE_MODE_4模式中的代码进行确认
测试代码vi配置
双sensor主要配置
SAMPLE_COMM_VI_GetSensorInfo(&stViConfig);
stViConfig.s32WorkingViNum = 2;
stViConfig.as32WorkingViId[0] = 0;
stViConfig.astViInfo[0].stSnsInfo.s32BusId = 1;
stViConfig.astViInfo[0].stSnsInfo.MipiDev = ViDev[0];
stViConfig.astViInfo[0].stDevInfo.ViDev = ViDev[0];
stViConfig.astViInfo[0].stDevInfo.enWDRMode = enWDRMode;
stViConfig.astViInfo[0].stPipeInfo.enMastPipeMode = enMastPipeMode;
stViConfig.astViInfo[0].stPipeInfo.aPipe[0] = ViPipe[0];
stViConfig.astViInfo[0].stPipeInfo.aPipe[1] = -1;
stViConfig.astViInfo[0].stPipeInfo.aPipe[2] = -1;
stViConfig.astViInfo[0].stPipeInfo.aPipe[3] = -1;
stViConfig.astViInfo[0].stChnInfo.ViChn = ViChn;
stViConfig.astViInfo[0].stChnInfo.enPixFormat = enPixFormat;
stViConfig.astViInfo[0].stChnInfo.enDynamicRange = enDynamicRange;
stViConfig.astViInfo[0].stChnInfo.enVideoFormat = enVideoFormat;
stViConfig.astViInfo[0].stChnInfo.enCompressMode = enCompressMode;
stViConfig.as32WorkingViId[1] = 1;
stViConfig.astViInfo[1].stSnsInfo.MipiDev = ViDev[1];
stViConfig.astViInfo[1].stSnsInfo.s32BusId = 5;
stViConfig.astViInfo[1].stDevInfo.ViDev = ViDev[1];
stViConfig.astViInfo[1].stDevInfo.enWDRMode = enWDRMode;
stViConfig.astViInfo[1].stPipeInfo.enMastPipeMode = enMastPipeMode;
stViConfig.astViInfo[1].stPipeInfo.aPipe[0] = ViPipe[1];
stViConfig.astViInfo[1].stPipeInfo.aPipe[1] = -1;
stViConfig.astViInfo[1].stPipeInfo.aPipe[2] = -1;
stViConfig.astViInfo[1].stPipeInfo.aPipe[3] = -1;
stViConfig.astViInfo[1].stChnInfo.ViChn = ViChn;
stViConfig.astViInfo[1].stChnInfo.enPixFormat = enPixFormat;
stViConfig.astViInfo[1].stChnInfo.enDynamicRange = enDynamicRange;
stViConfig.astViInfo[1].stChnInfo.enVideoFormat = enVideoFormat;
stViConfig.astViInfo[1].stChnInfo.enCompressMode = enCompressMode;
其中ViDev对应上面说到的devno
s32BusId为具体硬件接口上的i2c总线
主要修改就是这些地方.
主要测试了mipi0掊一路4lane sensor
mipi0,mipi1各接一路4lane sensor
mipi0,mipi2各接一路4lane sensor
都能正常进行编码
