MT6577 Android驱动设置：

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MT6577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\mt65xxlcmlist.c, 在lcmdriverlist [ lcmcount ] 中增加nt35510lcm_drv。

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

BUILDLK=yes //BUILDUBOOT=yes

BOOT_LOGO=wsvganl

CUSTOMKERNELLCM = nt35510

CUSTOMLKLCM= nt35510 // CUSTOMUBOOTLCM =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）

MTKLCMPHYSICAL_ROTATION=90

MTKTOUCHPHYSICALROTATIONRELATIVETOLCM=90

camera 旋转

Z:\jb2_131217\alps\mediatek\custom\hal\imgsensor\src\cfgsettingimgsensor.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 lcmgetparams(LCM_PARAMS *params){}

lcd rgb频率：

//params->dpi.mipipllclk_ref =536870912;

params->dpi.mipipllclk_ref= (33.3(167772168*2))/26; //33.3MHz

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

colorformat 修改

params->dpi.format = LCMDPIFORMATRGB888; // format is 24 bit//LCMDPIFORMATRGB666

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

defineSCREENMAXX 480

defineSCREENMAXY 800

1. leds 配置

CUSTOMKERNELLEDS= mt65xx

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

mediatek\custom\prj\lk\cust_leds.c

static structcustmt65xxled custledlist[MT65XXLEDTYPE_TOTAL] = {

{"red",MT65XXLEDMODE_NONE, -1,{0}},

{"green",MT65XXLEDMODE_NONE, -1,{0}},

{"blue",MT65XXLEDMODE_NONE, -1,{0}},

{"jogball-backlight",MT65XXLEDMODE_NONE, -1,{0}},

{"keyboard-backlight",MT65XXLEDMODE_NONE,-1,{0}},

{"button-backlight", MT65XXLEDMODE_NONE, -1,{0}}, // modify

{"lcd-backlight",MT65XXLEDMODEPWM,PWM1,{PWMCLKNEWMODEBLOCK,CLKDIV128,4,4}}, //modify

//{"lcd-backlight",MT65XXLEDMODECUST,(int)DISPSetBacklight,{0}},

};

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

mt65xxflashlighton(){}

mt65xxflashlightoff(){}

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@android:/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\java\android\os\PowerManager.java:

private staticfinal int MAXIMUMBACKLIGHT = android.os.PowerManager.BRIGHTNESSON;

1. Flash配置：

3.1 型号配置：

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

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

defineBOARDID MT6577EVB

defineCSPARTNUMBER[0] H9TP32A4GDMCPR_KDM

defineCSPARTNUMBER[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 Id的memeory 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

structpartnamemap gpartnamemap[PARTMAX_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\partitiontableMT6577.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)：

MEMORYDEVICEXLS =

mediatek\build\tools\emigen\$(MTKPLATFORM)\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

ifdefMTKEMMCSUPPORT

        .data_pins      = 8,

else

        .data_pins      = 4,

endif

        .data_offset    = 0,

ifdefMTKEMMCSUPPORT

               .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）：

26.2 modem源码工程编译（../prj/modem）

./make.shPRJ_HSPA.mak new

26.3 modem文件修改：

RF模块名配置：（安装项目区分定义文件夹名称）

\prj\modem\make\PRJ_HSPA.mak

GSM射频模块：RFMODULE = MT6162CUSTOM

3G射频模块：UMTSRFMODULE = CUSTOM_MT6162

26.5 modem库替换编译（..prj/alps/mediate/custom/common/modem）

CUSTOMMODEM=YOURMODEM

此编译表示：已将在modem源码工程中编译好的镜像放入MTKAndroid 工程中后，存放位置：

./mediatek/custom/common/modem/YOUR_MODEM

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，msdc1hw 结构体中的 flags 的 MSDCCDPINEN 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msdc1hw中的.cdlevel 设置成 MSDCCDLOW,否则设置成MSDCCDHIGH

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
