1. LCD

1.1怎样新建一个LCD驱动

LCD模组主要包括LCD显示屏和驱动IC。比如LF040DNYB16a模组的驱动IC型号为NT35510。要在MT577平台上新建这个lcd的驱动,步骤如下:

A.      新建文件夹nt35510:

\mediatek\custom\common\kernel\lcm\nt35510

\mediatek\custom\common\lk\lcm\nt35510 //\mediatek\custom\common\uboot\lcm\nt35510 

 

B.修改\mediatek\custom\common\kernel\lcm\mt65xx_lcm_list.c, 在lcm_driver_list [ lcm_count ] 中增加nt35510_lcm_drv。

C.打开mediatek\config\ginwave73_gb\ProjectConfig.mk:

BUILD_LK=yes //BUILD_UBOOT=yes

BOOT_LOGO=wsvganl

 

CUSTOM_KERNEL_LCM = nt35510

CUSTOM_LK_LCM= nt35510 // CUSTOM_UBOOT_LCM =nt35510

 

LCM_WIDTH=600

LCM_HEIGHT=1024

驱动文件移植原则:

根据具体平台,填充对应的函数,不能直接复制整个文件,避免不必要编译和接口错误。

 

1.3 LCD显示旋转(横竖屏旋转,关联到很多界面,需要统一修改)

方式一:横竖屏分辨率修改(还需要修改TP驱动):

LCM_WIDTH=1024

LCM_HEIGHT=600

 

方式二:lcm显示旋转,只需要修改:(还需要旋转camera驱动)

MTK_LCM_PHYSICAL_ROTATION=90

MTK_TOUCH_PHYSICAL_ROTATION_RELATIVE_TO_LCM=90

camera 旋转

Z:\jb2\_131217\alps\mediatek\custom\\hal\imgsensor\src\cfg_setting_imgsensor.cpp

    static SensorOrientation_T const inst = {

        u4Degree_0  : 180,//90,  //  main sensor in degree (0, 90,180, 270)

        u4Degree_1  : 0,//90,   //  sub  sensor in degree (0, 90, 180, 270)

 

 

1.4 lcm参数修改

\mediatek\custom\common\kernel\lcm\rgb_mt8193

staticvoid lcm_get_params(LCM_PARAMS *params){}

lcd rgb频率:

//params->dpi.mipi_pll_clk_ref  =536870912;

params->dpi.mipi_pll_clk_ref= (33.3*(16777216*8*2))/26;  //33.3MHz

//params->dpi.mipi_pll_clk_ref= 536870912;  //52.0MHz

colorformat 修改

params->dpi.format            = LCM_DPI_FORMAT_RGB888;   // format is 24 bit//LCM_DPI_FORMAT_RGB666

 

1.5 修改显示分辨率:

1.5.1配置修改:

打开mediatek\config\ginwave73_gb\ProjectConfig.mk:

LCM_WIDTH=600

LCM_HEIGHT=1024

Lk_logo= wsvganl 及相关logo文件修改

 

15.2 lcm驱动分辨率修改,可自行手动修改(注意横竖数值对应)

对应的lcm :\mediatek\custom\common\kernel\lcm\rgb_mt8193

#defineFRAME_WIDTH  (1024)

#defineFRAME_HEIGHT (600)

 

15.3 tpsensor driver修改,对应分辨率驱动(fae sensor提供驱动代码)。

\alps\mediatek\custom\prj\kernel\touchpanel\GSLx680\GSLx680.h

#defineSCREEN_MAX_X          480

#defineSCREEN_MAX_Y          800

 

 

2. leds 配置

CUSTOM_KERNEL_LEDS= mt65xx

 

mediatek\custom\prj\kernel\leds\mt65xx\cust_leds.c

mediatek\custom\prj\lk\cust_leds.c

static structcust_mt65xx_led cust_led_list[MT65XX_LED_TYPE_TOTAL] = {

{"red",MT65XX_LED_MODE_NONE, -1,{0}},

{"green",MT65XX_LED_MODE_NONE, -1,{0}},

{"blue",MT65XX_LED_MODE_NONE, -1,{0}},

{"jogball-backlight",MT65XX_LED_MODE_NONE, -1,{0}},

{"keyboard-backlight",MT65XX_LED_MODE_NONE,-1,{0}},

{"button-backlight",  MT65XX_LED_MODE_NONE, -1,{0}},      // modify

{"lcd-backlight",MT65XX_LED_MODE_PWM,PWM1,{PWM_CLK_NEW_MODE_BLOCK,CLK_DIV128,4,4}},          //modify

//{"lcd-backlight",MT65XX_LED_MODE_CUST,(int)DISP_SetBacklight,{0}},

};

 

..\mediatek\platform\mt6582\kernel\drivers\leds\leds.c

mt65xx_flashlight_on(){}

mt65xx_flashlight_off(){}

 

2.1 LED背光亮度修改:

mediatek\source\kernel\drivers\leds\leds.c

验证方式:adb shell查看:

shell@:/sys/class/leds/lcd-backlight$ cat max_brightness

备注:MMI层最亮、最暗背光调节代码:

./config.xml:

20

\alps\frameworks\base\core\\android\os\PowerManager.java:

private staticfinal int MAXIMUM_BACKLIGHT = android.os.PowerManager.BRIGHTNESS_ON;

 

 

3. Flash配置:

3.1 型号配置:

3.1.1 CUSTOM_MEMORY_HDR(需要确认是否是MTK认证的flash ic)

mediatek\custom\$(PROJECT)\preloader\inc\custom_MemoryDevice.h

#defineBOARD_ID                MT6577_EVB

#defineCS_PART_NUMBER[0]      H9TP32A4GDMCPR_KDM

#defineCS_PART_NUMBER[1]       KMKUS000VM_B410

备注:新增flash ic添加到此处,flash可以做到兼容;不能兼容相同IC Idmemeory ic.

 

3.2 特定项目不同类型分区定义信息(是否定义、顺序):

mediatek\custom\\kernel\core\src\partition.c

structpart_name_map g_part_name_map[PART_MAX_COUNT] = {

         {"preloader", PART_PRELOADER,       "rawdata",    0,       0,       0},

         {"dsp_bl",    PART_DSP_DL,     "rawdata",    1,       0,       0},

         {"mbr",        PART_MBR,          "raw data",    2,       1,       1},

         {"ebr1",        PART_EBR1,         "raw data",    3,       1,       1},

         {"pmt",        PART_PMT, "raw data",    4,       0,       0},

         {"nvram",     PART_NVRAM,     "rawdata",    5,       0,       0},

         {"seccfg",     PART_SECURE,    "raw data",    6,       0,       0},

         {"uboot",      PART_UBOOT,      "raw data",    7,       1,       1},

         {"boot",       PART_BOOTIMG,  "raw data",    8,       1,       1},

         {"recovery",  PART_RECOVERY,         "rawdata",    9,       1,       1},

         {"sec_ro",     PART_SECSTATIC,         "ext4",         10,     0,       0},

         {"misc",       PART_MISC,         "raw data",    11,     0,       0},

         {"logo",       PART_LOGO,        "raw data",    12,     1,       1},

         {"expdb",     PART_APANIC,     "raw data",    13,     0,       0},

         {"system",    PART_ANDSYSIMG,       "ext4",         14,     1,       1},

         {"cache",      PART_CACHE,      "ext4",         15,     1,       1},

         {"userdata",   PART_USER,         "ext4",         16,     1,       1},

         {"fat", PART_FAT,   "fat",  17,     0,       0},

};

 

3.3  emmc scat 分区大小设置(emmc) :

可对emmc进行分区,修改preloader\systemimage\userdata\FAT等各个分区。

\alps\mediatek\build\tools\ptgen\MT6577\partition_table_MT6577.xls

备注:Cache分区需要保持在512mb左右,否则系统会比较慢,响应迟缓。

 

3.4 FLASH参数配置文件位置(MemoryDeviceList_MT6577.xls)

MEMORY_DEVICE_XLS =

mediatek\build\tools\emigen\$(MTK_PLATFORM)\MemoryDeviceList_$(MTK_PLATFORM).xls

.xls文件含三个页面:

MT6577(page one):配置Flash Vendor Id 对应的硬件参数。

NAND(page two):

emmc_region(pagethree)

 

3.5 Flash驱动电压修改,读写速度方式修改:

mediatek\custom\konka73_gb\kernel\core\src\board.c

         struct msdc_hw msdc0_hw = {

            .clk_src        = 1,

            .cmd_edge       =MSDC_SMPL_FALLING,

            .data_edge      =MSDC_SMPL_FALLING,

            .clk_drv        = 5, //: 0 //memory驱动电压

            .cmd_drv       = 5, //: 0

            .dat_drv        = 5, // : 0

#ifdefMTK_EMMC_SUPPORT

            .data_pins      = 8,

#else

            .data_pins      = 4,

#endif

            .data_offset    = 0,

#ifdefMTK_EMMC_SUPPORT

                   .flags          = MSDC_SYS_SUSPEND | MSDC_HIGHSPEED,//memory读写速度

                   // .flags          = MSDC_SYS_SUSPEND | MSDC_HIGHSPEED |MSDC_UHS1 | MSDC_DDR,

                   //.flags                        = MSDC_SYS_SUSPEND,

#else

            .flags          =MSDC_SDCARD_FLAG,

#endif

 

3.6 emmc FAT分区划分:

emmc型号、emmc软件分区都会影响FAT分区的大小。

验证FAT Size需要对应emmc型号机器下载对应emmc软件分区的软件,不能预先下载FAT部分(影响实际FAT分区大小):

adb shell

cat /proc/emmc

cat /proc/partition获取大小。

 

4.GPIO/EINT/ADC/KEYPAD/PMIC 配置(根据原理图设计,可有原理硬件工程师指导填写即可):

7.camera

7.1 相关代码位置:

mediatek\config\XXXX(红色字为具体的项目名)

文件:ProjectConfig.mk

CUSTOM_KERNEL_IMGSENSOR = …… gc2235_raw

CUSTOM_KERNEL_MAIN_IMGSENSOR = …… gc2235_raw

CUSTOM_HAL_IMGSENSOR = …… gc2235_raw

CUSTOM_HAL_MAIN_IMGSENSOR = …… gc2235_raw

 

kernel:

\mediatek\custom\common\kernel\imgsensor\gc2235_raw

 

mediatek\custom\common\kernel\imgsensor\src

文件:kd_sensorlist.h

添加内容:

UINT32 GC2235SensorInit(PSENSOR_FUNCTION_STRUCT *pfFunc);

ACDK_KD_SENSOR_INIT_FUNCTION_STRUCT

kdSensorList[MAX_NUM_OF_SUPPORT_SENSOR+1] =

{

#if defined(GC2235_RAW)

    {GC2235_SENSOR_ID, SENSOR_DRVNAME_GC2235_RAW, GC2235SensorInit}, 

#endif

};

 

mediatek\custom\common\kernel\imgsensor\inc

文件:kd_imgsensor.h

添加内容:

#define GC2235_SENSOR_ID                 0x2235

#define SENSOR_DRVNAME_GC2235_RAW    "gc2235"

 

hal

\mediatek\custom\common\hal\imgsensor\gc2235_raw

 

mediatek\custom\common\hal\imgsensor\src

文件:sensorlist.cpp

添加内容:

MSDK_SENSOR_INIT_FUNCTION_STRUCT SensorList[] =

{

…………

#if defined(GC2235_RAW)

RAW_INFO(GC2235_SENSOR_ID, SENSOR_DRVNAME_GC2235_RAW, NULL), 

#endif

};

注意:在 kdSensorList  SensorList里面添加驱动的时候要注意,Sensor添加的位置要一样。否则驱动会跑乱,轻则 ISP参数不对,重则 Sensor 无法启动。

    CAPTURE_SIZE_640_480,

    CAPTURE_SIZE_1280_960,CAPTURE_SIZE_1600_1200,

)

 

7.3 Camera物理角度旋转

执行如下编译命令:./mk update-modem,这个命令会依次做如下步骤:

1. custgen     2. check modem      3. sign modem        4.update modem

29.SD卡

27.1热插拔功能

1,sd卡热插拔机制的实现需要软件和硬件同时配合才能实现。

2,在电路上,需要一根单独的检测pin脚,通过检测pin脚的高低电平来检测sd卡的插拔动作,并在dws中将其配置成上拉或下拉

3,软件上的配置主要就是在\mediatek\custom\\kernel\core\src\board.c中,msdc1_hw 结构体中的 flags 的 MSDC_CD_PIN_EN 和MSDC_REMOVABLE,这两个flag是热插拔的flag,如果不需要热插拔,请把这两个flag移除。

4,如果是低电平触发,将msdc1_hw中的.cd_level  设置成 MSDC_CD_LOW,否则设置成MSDC_CD_HIGH

 

备注:

(1),从hardware的角度,sd 卡槽中的CD 引脚与chip的EINT的某个脚连在一起,且chip内部会有上拉电阻。

(2),dct的配置如下:


注:EINT16使用的哪个GPIO,可以参考硬件hw_config.xls文档
