一：源代码下载：

1：Installing Repo

# mkdir ~/bin
# PATH=~/bin:$PATH

# curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
# chmod a+x ~/bin/repo

有可能出现如下错误

amp-server@ampserver:~$ curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
% Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed
0 0 0 0 0 0 0 0 --:--:-- 0:04:00 --:--:-- 0curl: (7) Failed to connect to 2404:6800:4005:c00::88: Network is unreachable

下面为两种解决办法，任何一种都可以

1. # curl "http://php.webtutor.pl/en/wp-content/uploads/2011/09/repo" >~/bin/repo

2. 打开 gedit /etc/hosts

添加如下内容：
74.125.237.1   dl-ssl.google.com

1：生成public key

#ssh-keygen -t rsa

#cd ~/.ssh

#cat id_rsa.pub

2.下载code

repo init -u ssh://git@openlinux.amlogic.com/jellybean/platform/manifest.git -b jb-mr1-amlogic
repo init -m openlinux_tablet_jb-mr1-amlogic_20130630.xml
repo sync

二：调试记录

1:android本身的机制，调节volume时不会去控制声卡上的寄存器，而是通过软件算法将volume调大或者调小。声卡控制的音频输出有好几路，每一路都有vol和gain控制着音量大小。

#cat /sys/class/sound/card0/device/RT5631/codec_reg →察看寄存器值

# tinymix 15 20 → Speaker Playback Volume设置为20

# tinymix 18 20 → HP Playback Volume设置为20

B:调试kernel、root；进入uboot命令行

m6_asd_ad7#mmcinfo;fatload mmc 0:1 0x82000000 boot.img;bootm

2:打开流量使用情况功能

                 i = insertAccountsHeaders(target, headerIndex);

3:打开3G Dongle

\device\amlogic\MID30801\overlay\frameworks\base\core\res\res\values\config.xml 

   <string-array translatable="false" name="networkAttributes">

4:uboot单独烧录

# mmcinfo;fatload mmc 0:1 82000000 u-boot.bin;nand rom_write 82000000 0 60000

5:按power键，不显示充电符号

将启动参数

charging_or_not=if ac_online; then run prepare; run charging; else if getkey; then run prepare; bmp display ${poweron_offset}; run bootcmd; else run power_off; fi; fi

改为

charging_or_not=if getkey; then run prepare; bmp display ${poweron_offset}; run bootcmd; else if ac_online; then run prepare; run charging; else run power_off; fi; fi

6:背光调节

# echo 100 > /sys/class/backlight/aml-bl/brightness

7:AXP202

查看寄存器0x30的值，打开权限

# echo 30 > /sys/devices/i2c-2/2-0034/axp20_reg

# cat /sys/devices/i2c-2/2-0034/axp20_reg

寄存器0x30写入0x63将usb供电不限流

# echo 3063 > /sys/devices/i2c-2/2-0034/axp20_reg

8:生成uImage_usb_burning用于USB烧录

# cd bootable/recovery/ && mm -B && cd -

# cp out/target/product/g24ref/system/bin/recovery out/target/product/g24ref/recovery/root/sbin/

# make otapackage -j24

# ./device/amlogic/g24ref/quick_build_kernel.sh recoveryimage meson6_g24_usb_burning_defconfig

执行后生成out/target/product/g24ref/recovery.img，改名为uImage_usb_burning

9:开机logo修改

1)uboot启动画面

图片要求：16bit BMP格式，直接改成下面文件就好

device/amlogic/g24ref/res_pack/poweron

device/amlogic/g24ref/res_pack/bootup

2)android启动画面

frameworks/base/core/res/assets/images/android-logo-mask.png

frameworks/base/core/res/assets/images/android-logo-shine.png

只要替换掉上面的图标即可

如果图片名字修改了，修改代码

3)initlogo.rle的制作

用图片工具编辑好想要的png之后,保存为logo.png
# convert -depth 8 logo.png rgb:logo.raw
# (SRC_HOME)/out/host/linux-x86/bin/rgb2565 -rle <logo.raw >initlogo.rle

4)bootanimation.zip的制作

# zip -r -X -Z store ../bootanimation part*/*.png desc.txt

10:打开/system权限

用mount命令查看分区情况

shell@android:/ $ mount
rootfs / rootfs rw 0 0
tmpfs /dev tmpfs rw,nosuid,relatime,size=413096k,nr_inodes=75476,mode=755 0 0

# mount -o remount /dev/block/system /system

11:分辨率修改

其中要修改的文件有如下6个文件：

uboot/customer/board/configs/m6_chinach_v1.h

uboot/customer/include/panel/CH7026.h

common/customer/include/panel/CH7026.h

common/customer/configs/meson6_g24_jbmr1_defconfig

device/amlogic/g24ref/set_display_mode.sh

common/customer/boards/board-m6g24.h

1）uboot/customer/board/configs/m6_chinach_v1.h

2）uboot/customer/include/panel/CH7026.h

3）common/customer/include/panel/CH7026.h

4) common/customer/configs/meson6_g24_jbmr1_defconfig

5) device/amlogic/g24ref/set_display_mode.sh

6) common/customer/boards/board-m6g24.h

12:关闭kernel打印信息

# echo 0 > /proc/sys/kernel/printk

13:ADC keypad

# cat /sys/class/saradc/saradc_ch4

14:编译自己的bin文件到system

如果Androidmk文件不加入LOCAL_MODULE_TAGS := eng，编译时报如下错误。想要让编译器默认把data_integrity_guard编译到系统里面，就必须在user_tags.mk加上如下提示的dig

build/core/base_rules.mk:79: *** Module name: dig
build/core/base_rules.mk:80: *** Makefile location: system/core/data_integrity_guard

build/core/base_rules.mk:103: *** user tag detected on new module - user tags are only supported on legacy modules.  Stop.

15:打开adb调试模式

# setprop sys.usb.config adb

16:android4.2.2+rtl8723bs

1) Wifi调试

wifi调试比较容易，根据realtek给的文档就能够轻松的调通，这里就不详细讲解了。要强调一点的就是，如果编译出来的ko文件很大，Makefile文件加上：

EXTRA_LDFLAGS += --strip-debug

2) BT调试

这里我不得不想fuck TMD，怎么形容amlogic都不过分，连UART驱动都做不好，搞出来异类。

realtek给出来的code一般都是比较通用，所以根据他们的文档移植不会有太大的问题。因为amlogic的问题，导致我用了3天才调通，他们家的UART没有用到奇偶检验，所以BT无法正常使用，下面是有问题的波形。

hal层怎么设置uart参数都没任何反应，uart驱动修改如下：

从新编译烧录，量出波形，一切正常

17:recovery[SetLocale]

aml8726-mx平台一般升级时会解析factory_update_param.aml文件

--wipe_cache
--wipe_data
--wipe_media

--locale=en_US 语言提示来设置为英文

--locale=zh_CN 语言提示来设置为中文

--update_package=/sdcard/update.zip

18：contrast、brightness、saturation调节

# echo 0 > /sys/class/video/contrast
# echo 25 > /sys/class/video/brightness
# echo 120 > /sys/class/video/saturation

19:默认输入法

# vi frameworks/base/packages/SettingsProvider/res/values/defaults.xml

修改如下

- <string name="config_defaultIME">com.android.inputmethod.latin/.LatinIME</string>
+ <string name="config_defaultIME">com.android.inputmethod.pinyin/.PinyinIME</string>
