海思Hi3519AV100sensor移植之二-- imx586 sensor

• 请先下载文档sensor 移植指南，以及imx586规格书，imx586寄存器excel。读一遍
• 跟厂商要一份imx586的初始化序列
• 驱动代码(只是能驱动，　并不包含isa调节功能)

 

由于本次的sensor转接板是公司自制， 所以先测试硬件通信。 

1. I2C通信

i2c_write 0x1 0x34 0x0100  0x01 2 1 
i2c_read 0x1 0x34 0x0100  0x0100 2 1 1

先写后读， 就可以判断I2C是不是写成功

2. 驱动修改

2.1  基于imx291的驱动(imx291_sensor_ctl.c )进行修改， 遵循FAE给的初始化序列修改寄存器即可，示意代码如下(太长了只能截取部分)

const unsigned short IMX291_SETTING_SHORT[]=
{
  //6000*8000 change on 20200225 , receive documents from the saler 
//EXCK_FREQ 24MHZ ==    
0x0136, 0x18,
0x0137, 0x00,
//EXCK_FREQ 24MHZ ==

0x3C7F, 0x03,
0x0111, 0x02,

0x4D99, 0x3C,
0x4D9B, 0x17,
0x4D9D, 

...

2.2按照《sensor调试指南》修改文件，主要集中在sample_comm_vi.c , sample_comm_isp.c

• 下面为驱动程序分析

原文件为sample_comm_isp.c

HI_S32 SAMPLE_COMM_ISP_Sensor_Regiter_callback(ISP_DEV IspDev, HI_U32 u32SnsId)
{
    ALG_LIB_S stAeLib;
    ALG_LIB_S stAwbLib;
    const ISP_SNS_OBJ_S* pstSnsObj;
    HI_S32    s32Ret = -1;

    if (MAX_SENSOR_NUM <= u32SnsId)
    {
        SAMPLE_PRT("invalid sensor id: %d\n", u32SnsId);
        return HI_FAILURE;
    }

    pstSnsObj = SAMPLE_COMM_ISP_GetSnsObj(u32SnsId);

    if (HI_NULL == pstSnsObj)
    {
        SAMPLE_PRT("sensor %d not exist!\n", u32SnsId);
        return HI_FAILURE;
    }

 

跳入SAMPLE_COMM_ISP_GetSnsObj，发现原来是缺少了stSnsImx586Obj;所以我在这里添加了相应的代码

    switch (enSnsType)
    {

        
        case SONY_IMX290_MIPI_2M_30FPS_12BIT:
        case SONY_IMX290_MIPI_2M_30FPS_12BIT_WDR2TO1:
            return &stSnsImx290Obj;
       /*添加的代码*/
        case SONY_IMX586_MIPI_2M_30FPS_12BIT:            
            return &stSnsImx586Obj;
        ...
    }

该结构体定义在

imx290_cmos.c ； 添加stSnsImx586Obj

ISP_SNS_OBJ_S stSnsImx586Obj =
{
    .pfnRegisterCallback    = sensor_register_callback,
    .pfnUnRegisterCallback  = sensor_unregister_callback,
    .pfnStandby             = imx291_standby,
    .pfnRestart             = imx291_restart,
    .pfnMirrorFlip          = HI_NULL,
    .pfnWriteReg            = imx291_write_register,
    .pfnReadReg             = imx291_read_register,
    .pfnSetBusInfo          = imx291_set_bus_info,
    .pfnSetInit             = sensor_set_init
};

定义在.c文件所有肯定是外部引用，extern , 位置

hi_sns_ctrl.h ； 同理添加 extern ISP_SNS_OBJ_S stSnsImx586Obj

extern ISP_SNS_OBJ_S stSnsMn34220Obj;
extern ISP_SNS_OBJ_S stSnsImx377Obj;
extern ISP_SNS_OBJ_S stSnsImx299Obj;
extern ISP_SNS_OBJ_S stSnsImx477Obj;
extern ISP_SNS_OBJ_S stSnsImx299SlvsObj;
extern ISP_SNS_OBJ_S stSnsImx290Obj;
extern ISP_SNS_OBJ_S stSnsImx327Obj;
extern ISP_SNS_OBJ_S stSnsImx334Obj;
extern ISP_SNS_OBJ_S stSnsOV2718Obj;
extern ISP_SNS_OBJ_S stSnsCmv50000Obj;
extern ISP_SNS_OBJ_S stSnsImx277SlvsObj;
extern ISP_SNS_OBJ_S stSnsImx117Obj;
extern ISP_SNS_OBJ_S stSnsImx290SlaveObj;
extern ISP_SNS_OBJ_S stSnsImx334SlaveObj;
extern ISP_SNS_OBJ_S stSnsImx226Obj;
extern ISP_SNS_OBJ_S stSnsImx335Obj;
extern ISP_SNS_OBJ_S stSnsImx458Obj;
/*添加的代码*/
extern ISP_SNS_OBJ_S stSnsImx586Obj;

3. 使用示波器测量　Power信号， VANA, VDIG, VIF, 三个信号电平符合要求

4. 输入时钟信号INCK, 按照文档，该时钟输入应为6-27MHz.

4.1修改sys_config.c,  我这里用的是27M.

static BUS_TYPE parse_sensor_bus_type(char *name)
{
    unsigned int len;
    BUS_TYPE bus_type = BUS_TYPE_I2C;

    len = SENSOR_NAME_LEN;

    if (   (0 == strncmp("imx377", name, len))
        || (0 == strncmp("imx334", name, len))
        || (0 == strncmp("imx477", name, len))
        || (0 == strncmp("imx290", name, len))
        || (0 == strncmp("imx290_slave", name, len))
        || (0 == strncmp("imx299", name, len))
        || (0 == strncmp("imx117", name, len))
//添加代码
        || (0 == strncmp("imx586", name, len)))
    {
        bus_type = BUS_TYPE_I2C;
    }
    else if ((0 == strncmp("imx299_slvs", name, len))
          || (0 == strncmp("cmv50000", name, len))
          || (0 == strncmp("imx277_slvs", name, len))
          || (0 == strncmp("imx117", name, len))
          || (0 == strncmp("imx226", name, len)))
    {
        bus_type = BUS_TYPE_SPI;
    }
    else
    {
        printk("FUNC:%s line:%d  SNS:[%s] is not supported !\n", __FUNCTION__,__LINE__, name);
        bus_type = BUS_TYPE_I2C;
    }

    return bus_type;
}

/*

*/
static unsigned int parse_sensor_clock(char *name)
{
    unsigned int clock = 0x0;
    unsigned int len;

    len = SENSOR_NAME_LEN;

    if ( (0 == strncmp("imx377", name, len))
         || (0 == strncmp("imx334", name, len))
         || (0 == strncmp("imx477", name, len))
         || (0 == strncmp("imx299", name, len))
         || (0 == strncmp("cmv50000", name, len)))
    {
        clock = 0x4;
    }
    else if (0 == strncmp("imx290", name, len))
    {
        clock = 0x8;
    }
    else if (0 == strncmp("imx290_slave", name, len))
    {

              || (0 == strncmp("imx226", name, len)))
    {
        clock = 0x1;
    }
//
    else if(0 == strncmp("imx586", name, len))
    {	//27M
    	clock = 0xA;
    }
    else
    {
        printk("FUNC:%s line:%d  SNS:[%s] is not supported !\n", __FUNCTION__, __LINE__, name);
        return clock;
    }

    return clock;
}

将编译好的sys_config.ko 拷贝到海思的/usr/ko目录下

4.2 运行脚本

cd /usr/ko
./load3519av100 -r
./load3519av100 -i sensor0 imx586

 

5 使用示波器测量复位信号：CMOS_RSTN,  mipi data信号

6. isa 算法调节
