msm8909+android5.1.1编译前配置及增加新项目和产品所需分支

编译前的选项配置：

(1)source build/envseutp.sh

(2)choosecomb

1.source build/envsetup.sh

source 是用来运行 shell 脚本的命令 功能和 "." 和相同，因此 也可以写作： . build/envsetup.sh

下面我们具体来看每个选项的内容

2.1 project choices(项目选择)

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54

Project choices are: 1 . CB03 Which would you like? [CB03] 1 实现如下： PROJECT_CHOICES=(CB03 C6000) function chooseproject() { T=$(gettop) #获取Android源码根目录 echo "Project choices are:" local index= 1 local v for v in ${PROJECT_CHOICES[@]} do # The product name is the name of the directory containing # the makefile we found, above. echo "     $index. $v" #比如显示 1 .CB03 index=$(($index+ 1 )) done local default_value=CB03 local ANSWER export SIMCOM_PROJECT=  #导出环境变量 while [ -z "$SIMCOM_PROJECT" ] do echo -n "Which would you like? [$default_value] " if [ -z "$1" ] ; then read ANSWER else echo $ 1 ANSWER=$ 1 fi if [ -z "$ANSWER" ] ; then export SIMCOM_PROJECT=$default_value elif (echo -n $ANSWER | grep -q -e "^[0-9][0-9]*$" ) ; then if [ "$ANSWER" -le "${#PROJECT_CHOICES[@]}" ] ; then exportSIMCOM_PROJECT=${PROJECT_CHOICES[$(($ANSWER- 1 ))]} fi else if check_project $ANSWER then export SIMCOM_PROJECT=$ANSWER else echo "** Not a validproject: $ANSWER" fi fi if [ -n "$1" ] ; then break fi done }

这里导出了SIMCOM_PROJECT变量的值，比如C6000

加入我们要增加另个工程，比如C6000，要修改PROJECT_CHOICES的值，

修改前：

PROJECT_CHOICES=(CB03)

修改后：

PROJECT_CHOICES=(CB03 C6000)

中间不能用逗号。

基于上面的修改，所有项选择之后输出

read(): can't openbuild/buildplus/namespace/names.ini for read: 没有那个文件或目录 atbuild/buildplus/tool/qrdplus_target_gen.pl line 98.

target build Env generate failed, yourshould abort continuous make procedure!

此错误信息是initbuildspec()输出的

?

1 2 3 4 5 6 7 8 9 10

function initbuildspec() { local -a GEN_QRDPLUS_ENV_RET GEN_QRDPLUS_ENV_PL=build/buildplus/tool/qrdplus_target_gen.pl #modify by lzq default mode is ct GEN_QRDPLUS_ENV_RET=(`perl $GEN_QRDPLUS_ENV_PL $SIMCOM_PROJECT`) if [ "$GEN_QRDPLUS_ENV_RET" != "GEN_SUCCESS" ] ;then echo "target build Env generate failed, your should abortcontinuous make procedure!" fi }

这里会找build\buildplus\namespace\目录下是否有names_ $(SIMCOM_PROJECT).ini的文件。所以需要在此目录下增加names_C6000.ini文件才可以编译通过。

2.2 build type选择

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58

Build type choices are: 1 . release 2 . debug Which would you like? [ 1 ] 1 实现如下： function choosetype() { echo "Build type choices are:" echo "     1. release" echo "     2. debug" echo local DEFAULT_NUM DEFAULT_VALUE DEFAULT_NUM= 1 DEFAULT_VALUE=release export TARGET_BUILD_TYPE= local ANSWER while [ -z $TARGET_BUILD_TYPE ] do echo -n "Which would you like? [" $DEFAULT_NUM "] " if [ -z "$1" ] ; then read ANSWER else echo $ 1 ANSWER=$ 1 fi case $ANSWER in "" ) export TARGET_BUILD_TYPE=$DEFAULT_VALUE ;; 1 ) export TARGET_BUILD_TYPE=release ;; release) export TARGET_BUILD_TYPE=release ;; 2 ) export TARGET_BUILD_TYPE=debug ;; debug) export TARGET_BUILD_TYPE=debug ;; *) echo echo "I didn't understand your response.  Please try again." echo ;; esac if [ -n "$1" ] ; then break fi done set_stuff_for_environment # 设置环境变量 }

这里导出环境变量TARGET_BUILD_TYPE，其值为release或是debug，调用set_stuff_for_environment()来设置环境变量，如下：

?

1 2 3 4 5 6 7 8 9 10 11

function set_stuff_for_environment() { settitle set_java_home setpaths set_sequence_number export ANDROID_BUILD_TOP=$(gettop) #With this environment variable new GCC can apply colors to warnings/errors exportGCC_COLORS= 'error=01;31:warning=01;35:note=01;36:caret=01;32:locus=01:quote=01' }

2.3 product choices(产品选择)

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81

Product choices are: 1 . msm8909 Which product would you like? [msm8909] 1 实现如下： # # This function isn't really right:  It chooses a TARGET_PRODUCT # based on the list of boards.  Usually, that gets you something # that kinda works with a generic product,but really, you should # pick a product by name. # function chooseproduct() { # Find the list of all products by lookingfor all AndroidProducts.mk files under the # device/, vendor/ andbuild/target/product/ directories and look for the format # LOCAL_DIR/<productspecificfile.mk>and extract the name ProductSpecificFile from it. # This will give the list of all productsthat can be built using choosecombo local -a prodlist # Find all AndroidProducts.mk files underthe dirs device/, build/target/ and vendor/ # Extract lines containing .mk from them # Extract lines containing LOCAL_DIR # Extract the name of the product specificfile prodlist=(`/usr/bin/find device/qcom/msm8909 -name AndroidProducts.mk2>/dev/ null | xargs grep -h \.mk| grep LOCAL_DIR| cut -d '/' -f2|cut -d ' ' -f1|sort|uniq|cut -d '.' -f1`) export TARGET_PRODUCT= local index= 1 local p echo "Product choices are:" for p in ${prodlist[@]} do echo "     $index. $p" let "index = $index + 1" done if [ "x$TARGET_PRODUCT" != x ] ; then default_value=$TARGET_PRODUCT else default_value=msm8909 fi local ANSWER while [ -z "$TARGET_PRODUCT" ] do echo -n "Which product would you like? [$default_value] " if [ -z "$1" ] ; then read ANSWER else echo $ 1 ANSWER=$ 1 fi if [ -z "$ANSWER" ] ; then export TARGET_PRODUCT=$default_value elif (echo -n $ANSWER | grep -q -e "^[0-9][0-9]*$" ) ; then local poo=`echo -n $ANSWER` if [ $poo -le ${#prodlist[@]} ] ; then exportTARGET_PRODUCT=${prodlist[$(($ANSWER- 1 ))]} else echo "** Bad productselection: $ANSWER" fi else if check_product $ANSWER then export TARGET_PRODUCT=$ANSWER else echo "** Not a validproduct: $ANSWER" fi fi if [ -n "$1" ] ; then break fi done set_stuff_for_environment }</productspecificfile.mk>

这里有几个重要的信息：

(1)通过查找device、vendor和build/target/product/下AndroidProducts.mk文件来寻找所有的产品，寻找此目录下LOCAL_DIR/文件和提取名为ProductSpecificFile的文件

比如\device\qcom\msm8909\ AndroidProducts.mk，此文件内容如下：

PRODUCT_MAKEFILES := \

$(LOCAL_DIR)/msm8909.mk

提取msm8909.mk文件，msm8909就是一个产品。

我们如果要增加一个C6000的产品，需要做下面的处理：

(1)\device\qcom

基于此目录的msm8909产品，增加C6000产品的目录，然后修改AndroidProducts.mk文件内容如下：

PRODUCT_MAKEFILES := \

$(LOCAL_DIR)/C6000.mk

所以还需要基于msm8909.mk改为C6000.mk，然后把C6000.mk中关于msm8909产品和项目名称为CB03的地方统一修改为C6000，但其中引用到的mixer_paths_msm8909_pm8916.xml文件这里的msm8909不需要改为C6000，因为共用msm8909处理器，也需要把device\qcom\C6000\overlay\CB03改为C6000

(2)\vendor\qcom

没有修改

(3)build/target/product/

没有修改

(4)envsetup.sh从device/qcom枚举所有的产品名

prodlist=(`/usr/bin/finddevice/qcom/msm8909 -name AndroidProducts.mk 2>/dev/null|

这是自带的，如果枚举所有的，可改为device/qcom，如果只想枚举指定的，比如msm8909和C6000，可改为

prodlist=(`/usr/bin/finddevice/qcom/msm8909 device/qcom/C6000 -name AndroidProducts.mk 2>/dev/null|

(5)导出TARGET_PRODUCT，其值为msm8909或是C6000

(6)设置产品名称的显示顺序

?

1 2 3 4 5 6 7 8 9

prodlist=(`/usr/bin/finddevice/qcom/msm8909 device/qcom/C6000 -name AndroidProducts.mk 2 >/dev/ null | xargs grep -h \.mk| grep LOCAL_DIR| cut -d '/' -f2|cut -d ' ' -f1|sort|uniq|cut -d '.' -f1`) 显示结果 Product choices are: 1 . C6000 2 . msm8909

这种方式会根据字母顺序来显示，如果想按照自己制定的顺序来显示，如下：

?

1 2 3 4 5 6 7 8 9

prodlist=(`/usr/bin/finddevice/qcom/msm8909 device/qcom/C6000 -name AndroidProducts.mk 2 >/dev/ null | xargs grep -h \.mk| grep LOCAL_DIR| cut -d '/' -f2|cut -d '.' -f1`) 显示结果 Product choices are: 1 . msm8909 2 . C6000

2.4 variant choices不同的选择

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54

Variant choices are: 1 . user 2 . userdebug 3 . eng Which would you like? [eng] 1 实现如下： VARIANT_CHOICES=(user userdebug eng) function choosevariant() { echo "Variant choices are:" local index= 1 local v for v in ${VARIANT_CHOICES[@]} do # The product name is the name of the directory containing # the makefile we found, above. echo "     $index. $v" index=$(($index+ 1 )) done local default_value=eng local ANSWER export TARGET_BUILD_VARIANT= while [ -z "$TARGET_BUILD_VARIANT" ] do echo -n "Which would you like? [$default_value] " if [ -z "$1" ] ; then read ANSWER else echo $ 1 ANSWER=$ 1 fi if [ -z "$ANSWER" ] ; then export TARGET_BUILD_VARIANT=$default_value elif (echo -n $ANSWER | grep -q -e "^[0-9][0-9]*$" ) ; then if [ "$ANSWER" -le "${#VARIANT_CHOICES[@]}" ] ; then exportTARGET_BUILD_VARIANT=${VARIANT_CHOICES[$(($ANSWER- 1 ))]} fi else if check_variant $ANSWER then export TARGET_BUILD_VARIANT=$ANSWER else echo "** Not a validvariant: $ANSWER" fi fi if [ -n "$1" ] ; then break fi done }

导出环境变量TARGET_BUILD_VARIANT，其值为(user userdebug eng)三选一。

2.5 chipset

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51

chipset are: 1 . 8909 2 . 8209 Which would you like? [ 8909 ] 1 CHIPSET=( 8909 8209 ) function choose_CHIPSET() { echo "chipset are:" local index= 1 local v for v in ${CHIPSET[@]} do # The product name is the name of the directory containing # the makefile we found, above. echo "     $index. $v" index=$(($index+ 1 )) done local default_value= 8909 local ANSWER export TARGET_CHIPSET= while [ -z "$TARGET_CHIPSET" ] do echo -n "Which would you like? [$default_value] " if [ -z "$1" ] ; then read ANSWER else echo $ 1 ANSWER=$ 1 fi if [ -z "$ANSWER" ] ; then export TARGET_CHIPSET=$default_value elif (echo -n $ANSWER | grep -q -e "^[0-9][0-9]*$" ) ; then if [ "$ANSWER" -le "${#CHIPSET[@]}" ] ; then exportTARGET_CHIPSET=${CHIPSET[$(($ANSWER- 1 ))]} fi else if check_variant $ANSWER then export TARGET_CHIPSET=$ANSWER else echo "** Not a validvariant: $ANSWER" fi fi if [ -n "$1" ] ; then break fi done }

导出环境变量TARGET_CHIPSET，其值为8909或是8209。

2.6 multisim choices

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71

Multisim choices are: 1 . ssss 2 . dsds Which would you like? [ssss] 1 MULTISIM_CHOICES=(ssss dsds) function chooseMultisim() { T=$(gettop) export SIMCOM_MULTISIM= local choose_multisim= local default_value= case $SIMCOM_PROJECT in "CB03" ) choose_multisim= 1 default_value=ssss ;; *) choose_multisim= 1 default_value=ssss ;; esac if [ $choose_multisim -eq 1 ] ; then echo "Multisim choices are:" local index= 1 local v for v in ${MULTISIM_CHOICES[@]} do echo "     $index. $v" index=$(($index+ 1 )) done local ANSWER while [ -z "$SIMCOM_MULTISIM" ] do echo -n "Which would you like? [$default_value] " if [ -z "$1" ] ; then read ANSWER else echo $ 1 ANSWER=$ 1 fi if [ -z "$ANSWER" ] ; then export SIMCOM_MULTISIM=$default_value elif (echo -n $ANSWER | grep -q -e "^[0-9][0-9]*$" ) ; then if [ "$ANSWER" -le "${#MULTISIM_CHOICES[@]}" ] ;then exportSIMCOM_MULTISIM=${MULTISIM_CHOICES[$(($ANSWER- 1 ))]} fi else if check_multisim $ANSWER then export SIMCOM_MULTISIM=$ANSWER else echo "** Not a validmultisim: $ANSWER" fi fi if [ -n "$1" ] ; then break fi done fi }

导出环境变量SIMCOM_MULTISIM，其值为ssss或是dsds

基于上面的修改后，然后编译C6000，make –j4，遇到的问题如下：

(1)make: *** 没有规则可以创建目标“build/scm_scripts/C6000.mk”。 停止

envsetup.sh下关于我们make这个动作的函数如下

?

1 2 3 4 5 6 7 8 9 10

function m() { local T=$(gettop) local DRV=$(getdriver $T) if [ "$T" ]; then $DRV make -C $T -f build/core/main.mk [email protected] else echo "Couldn't locate the top of the tree.  Try setting TOP." fi }

可知会调用build/core/main.mk，此文件下通过TARGET_PRODUCT和SIMCOM_PROJECT环境变量搜索，相关部分如下

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

$(info********************************************) ifneq (,$(SIMCOM_PROJECT)) $(info !   override withvendor/simcom/$(SIMCOM_PROJECT)    !) $(shell cp -rfvendor/simcom/$(SIMCOM_PROJECT)/frameworks ./) $(shell cp -rfvendor/simcom/$(SIMCOM_PROJECT)/packages ./) else $(info SIMCOM_PROJECT is null !) endif $(info********************************************) includebuild/buildplus/target/QRDExt_target.min ifeq ($(Module_Nfc_Pn547), yes) $(info !   override withvendor/simcom/Nfc_Pn547 !) $(shell cp -rf vendor/simcom/Nfc_Pn547/*./) endif #ifeq (build/scm_scripts/$(SIMCOM_PROJECT)_$(TARGET_CUSTOMER).mk,$(wildcard build/projectEnv/$(TARGET_PRODUCT)_$(TARGET_CUSTOMER).mk)) #includebuild/scm_scripts/$(SIMCOM_PROJECT)_$(TARGET_CUSTOMER).mk # else includebuild/scm_scripts/$(SIMCOM_PROJECT).mk #endif

可知要创建build/scm_scripts/C6000.mk这个文件，然后编译

(2)make: *** 没有规则可以创建“out/target/product/C6000/obj/ETC/init.rc_intermediates/init.rc”需要的目标“system/core/rootdir/init_C6000.rc”。 停止

所以我们需要创建system/core/rootdir/init_C6000.rc

(3)Can't find defaultconfiguration "arch/arm/configs/msm8909-1gb-C6000-perf_defconfig"!

所以需要创建msm8909-1gb-C6000-perf_defconfig文件，此文件中的CONFIG_ARCH_MSM8909_CB03=y改为CONFIG_ARCH_MSM8909_C6000=y，此配置在\kernel\arch\arm\mach-msm\Kconfig用到，增加内容：

?

1 2 3 4 5

config ARCH_MSM8909_C6000 bool "C6000 Product" depends on ARCH_MSM8909 help Support for MSM8909 C6000.

(4)make: *** 没有规则可以创建“out/target/product/C6000/persist/WCNSS_qcom_wlan_nv.bin”需要的目标“device/qcom/C6000/WCNSS_qcom_wlan_nv_C6000.bin”。 停止。

把此目录下的WCNSS_qcom_wlan_nv_CB03.bin改为WCNSS_qcom_wlan_nv_C6000.bin

(5)make: ***[out/target/product/C6000/obj/PACKAGING/target_files_intermediates/C6000-target_files-eng.zip]错误 1

更多的编译错误信息如下：

?

1 2 3 4 5 6 7

Package target files:out/target/product/C6000/obj/PACKAGING/target_files_intermediates/C6000-target_files-eng.zip prepare the ota cp files.[vendor/simcom/C6000/mp_images] out/host/linux-x86/bin/acp     vendor/simcom/C6000/mp_images/NON-HLOS.bin             out/target/product/C6000/NON-HLOS.ota acp: file 'vendor/simcom/C6000/mp_images/NON-HLOS.bin' does not exist make: ***[out/target/product/C6000/obj/PACKAGING/target_files_intermediates/C6000-target_files-eng.zip]错误 1 #### make failed to build some targets( 39 : 57 (mm:ss)) ####

编译生成了所需要的系统文件，但少了misc.img、msm8909-otg-eng.zip、NON-HLOS.ota、Package_backup.zip、rpm.ota、sbl1.otg、splash.img、target_files-package.zip、tz.ota

可知需要vendor/simcom/C6000/mp_images文件夹下的NON-HLOS.bin文件来生成C6000-target_files-eng.zip文件，所以我们需要创建vendor/simcom/C6000文件夹及需要的文件，

(6)编译成功，但还是少了misc.img和splash.img

在vendor目录下搜索misc，发现vendor\qcom\proprietary\qrdplus\Extension\apps\BootAnimation\Android.mk文件相关内容如下：

?

1 2	$(shell cp -r$(LOCAL_PATH)/$(SIMCOM_PROJECT)/splash.img $(PRODUCT_OUT)/splash.img) $(shell cp -r$(LOCAL_PATH)/$(SIMCOM_PROJECT)/misc.img $(PRODUCT_OUT)/misc.img)

可知要拷贝BOOtAnimation目录下$(SIMCOM_PROJECT)下的splash.img、misc.img文件拷贝到$(PRODUCT_OUT)下，所以我们需要创建C6000的目录及需要的文件。

(7)烧录系统，开机的时候白屏，进入系统还是白屏，休眠唤醒后显示和TP正常

改为采用CB03编译出来的emmc_appsboot.mbn(uboot部分)就显示OK了，说明和uboot有关。

/c4050-q4/bootable/bootloader/lk/project/msm8909.mk文件增加

?

1 2 3

ifeq ($(SIMCOM_PROJECT), C6000) DEFINES += MSM8909_C6000= 1 Endif

bootable\bootloader\lk\target\msm8909\include\target\display.h

改为

?

1 2 3 4 5 6 7 8 9

# if (MSM8909_CB03 || MSM8909_C6000) static struct gpio_pin reset_gpio = { "msmgpio" , 8 , 3 , 1 , , 1 }; # else static struct gpio_pin reset_gpio = { "msmgpio" , 25 , 3 , 1 , , 1 }; #endif

然后显示就OK了。

(8)用CB03编译，大小为852MB；用C6000编译，大小为846MB

编译出来的系统在点击桌面应用图标的时候，有提示音，做下面的修改

\device\qcom\common\common.mk

ifneq (, $(filter CB03, $(SIMCOM_PROJECT)))

改为

ifneq (, $(filter CB03 C6000,$(SIMCOM_PROJECT)))

到此编译出来的烧录就不存在上面的问题。

(9)增加C6000相对应的设备树文件

\kernel\arch\arm\boot\dts\qcom\Makefile增加

dtb-$(CONFIG_ARCH_MSM8909) +=msm8909-sim.dtb \下面增加

dtb-$(CONFIG_ARCH_MSM8909_C6000) +=msm8909-1gb-qrd-skue-c6000.dtb

增加msm8909-1gb-qrd-skue-c6000.dts，此文件需要#include "msm8909-qrd-skue-c6000.dtsi"，所以需要增加msm8909-qrd-skue-c6000.dtsi文件

msm8909-qrd-skue-cb03.dtsi文件内容如下
