A527 android13调试TP9950

1.TP9950介绍：

TP9950是一款高清视频解码器，它支持高清传输视频接口（HD-TVI）视频、NTSC/PAL CVBS视频以及一些常见的高清模拟视频格式解码。

2.项目的硬件连接：

通道连接到了MIPIA上面

3.软件调试

3.1修改设备树适配摄像头：

        sensor1:sensor@5812010 {
                device_type = "sensor1";
                sensor1_mname = "tp9950";
                sensor1_twi_cci_id = <2>;
                sensor1_twi_addr = <0x88>;
                sensor1_mclk_id = <0>;
                sensor1_pos = "front";
                sensor1_isp_used = <0>;
                sensor1_fmt = <0>;
                sensor1_stby_mode = <0>;
                sensor1_vflip = <0>;
                sensor1_hflip = <0>;
                sensor1_cameravdd-supply = <>;
                sensor1_cameravdd_vol = <>;
                sensor1_iovdd-supply = <>;
                sensor1_iovdd_vol = <>;
                sensor1_avdd-supply = <>;
                sensor1_avdd_vol = <>;
                sensor1_dvdd-supply = <>;
                sensor1_dvdd_vol = <>;
                sensor1_power_en = <&pio PK 22 GPIO_ACTIVE_HIGH>;
                sensor1_reset = <&pio PK 11 GPIO_ACTIVE_LOW>;
                sensor1_pwdn = <>;//<&pio PJ 16 GPIO_ACTIVE_HIGH>;
                status = "okay";
        };

        vinc30:vinc@5833000 {
                vinc12_csi_sel = <0>;
                vinc12_mipi_sel = <0>;
                vinc12_isp_sel = <5>;
                vinc12_isp_tx_ch = <0>;
                vinc12_tdm_rx_sel = <0>;
                vinc12_rear_sensor_sel = <1>;
                vinc12_front_sensor_sel = <1>;
                vinc12_sensor_list = <0>;
                device_id = <12>;
                work_mode = <0x0>;
                status = "okay";
        };

3.2编写驱动

SDK里面的tp9950是并口的，需要根据tp2815_mipi的驱动修改：

在longan/kernel/linux-5.15/bsp/drivers/vin/modules/sensor下面添加tp9950_mipi.c文件，修改为mipi接口的格式

static struct sensor_format_struct sensor_formats[] = {
        {
                .desc           = "YUYV 4:2:2",
                .mbus_code = MEDIA_BUS_FMT_UYVY8_2X8,
                .regs = sensor_default_regs,
                .regs_size = ARRAY_SIZE(sensor_default_regs),
                .bpp = 2,
        },
};

适配对应的分辨率寄存器的值：

static struct regval_list reg_1280x720p25_1ch[] = {
   {0x40, 0},
    
	{0x41, 0x00},//AFE Test Register 
	{0x40, 0x08},//set PAGE 1

   {0x02, 0x42},
   {0x07, 0xc0},
   {0x0b, 0xc0},
   {0x0c, 0x13},
   {0x0d, 0x50},
   {0x15, 0x13},
   {0x16, 0x15},
   
   {0x17, 0x00},//500=1280
   {0x18, 0x19},
   {0x19, 0xd0},//2d0=720
   {0x1a, 0x25},
   
   {0x1c, 0x07},//1280*720, 25fps
   {0x1d, 0xbc},//1280*720, 25fps
   {0x20, 0x30},
   {0x21, 0x84},
   {0x22, 0x36},
   {0x23, 0x3c},
//   {0x2a, 0x3c},//PAGE0,默认信号是30,蓝屏是3C
   {0x2b, 0x60},
   {0x2c, 0x0a},
   {0x2d, 0x30},
   {0x2e, 0x70},
   {0x30, 0x48},
   {0x31, 0xbb},
   {0x32, 0x2e},
   {0x33, 0x90},
		
   {0x35, 0x25},
	//(0x35, 0x05},
		
   {0x38, 0x00},
   {0x39, 0x18},
    
   {0x02, 0x46},
   {0x0d, 0x71},
   {0x18, 0x1b},
   {0x20, 0x40},
   {0x21, 0x46},
   {0x25, 0xfe},

   {0x2d, 0x5a},
   {0x2e, 0x40},
   {0x30, 0x9e},
   {0x31, 0x20},
   {0x32, 0x10},
   {0x33, 0x90},
    
   {0x40, 0x08},
   {0x23, 0x02},
   {0x13, 0x24},
   {0x14, 0x46},
   {0x15, 0x09},
   {0x25, 0x08},
   {0x26, 0x01},
   {0x27, 0x0e},
   {0x10, 0x88},
   {0x10, 0x08},
   {0x23, 0x00},
   {0x40, 0x00},
};

3.3修改中间层

全志平台验证套片的摄像头用的是DVR APP，不能用原生的APP测试，所以中间层需要改为：USE_CAMERA_HAL_AUTO_1_0

USE_CAMERA_HAL_3_4 ?= false

USE_CAMERA_HAL_AUTO_1_0 ?= true

然后重新编译验证。
