經過之前的測試 , 發現非64 位元 不行 , 好吧 , Fedora 16 i686 更新成為 Fedora 18 x64 吧 !!
按照 TI 網頁的說明將 TI-Android-JB-4.1.2_AM335x_4.0.1.bin 下載 , 並且解開 .
先按照 TI 說明build 一次 , 將缺少的 package 和 有錯誤的修正 , 就可以在 AM335x_EVM_SK board 上凍做了 .
下列說明修改的部份:
A.建立一個環境設定 shell file. ( env.sh )
#!/bin/sh
#
# vi: set ts=4 :
## ======== setting PATH ========
TOOLCHAIN_BIN="${PWD}/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin"

PATH2=`echo ${PATH1} | sed "s|[:]${PWD}/build||g" | sed "s|${PWD}/build[:]||g"`
PATHE=${PATH2}
export PATH=${TOOLCHAIN_BIN}:${PWD}/build:${PATHE}
## ========
export USE_CCACHE=1
export CROSS_COMPILE=arm-eabi-
export ARCH=arm
export TARGET_PRODUCT=am335xevm_sk
export OMAPES=4.x
## ===================================
B. 和之前一樣會遇到 perl 版本不合, 修改 "make-hash-tools.pl" 檔案.
詳細請參考之前文章.

這樣就可以正確 在 Fedora 18 x64 下 build出所有東西 , 並可以在 am335xevm_sk 上執行!!
2013年3月22日 星期五
2013年2月18日 星期一
Start Build TI AM335X Android JB DevKit BSP in Fedora 16.
最近比較有空 (等PCB 回來驗證修改部份 ) , 所以在看看 TI 的 Android 吧 !!
發現 , TI release 的 Android JB for AM335x 的 BSP 了 .
一樣 在 FC16 上 build 看看吧 !! 我的 PC 還是 FC16 , 所以應該缺少的 東西不多 !
想說可以順利build 完畢 , 沒想到 .... 第一步就有問題 !!
Cross Compile 給我用 64 bit 的 ..... 我的 FC16 是 32bit 啦 !!!!
不想使用 VM machine (build 太慢) , 並且有舊的 project toolchain (32Bit ) .
好吧 , 試試看是否能 在 32 bit build .
PS. 這篇文章會陸續增加 修正的項目 .
A.先改 ./prebuilts/tools/gcc-sdk/gcc 吧.
原始檔案使用 file -L "$SHELL" 的方式再次檢查是否 64 bit. 感決覺有點多餘.
每次都用同樣方式檢查不就可以了 ?? 修改後的 diff 如下:

$MY_TOOL "$@"
這一版本沒有 32bit 的 target toolchain , 所以由 ICS 的 版本內將的 toolchain
arm-linux-androideabi-4.4.x 複製到
./prebuild/linux-x86/toolchain/ 目錄下!!
原本應該在 ./prebuilds 下 , 不過擔心 ICS 的 toolchain 會有內部指定位置 , 所以放在和
ICS 一樣的 ./prebuild/ 目錄下.
本篇最後會有一個 env.sh 的 file , 內容會說明如何將 toolchain 指定到這邊 !!
B.Java VM 沒有辦法開啟 .
只細看一下 error message , 好像 jave 的 heap memory 太大 , 修正 下面這個檔案
./build/core/definitions.mk , diff 內容如下:

C.修正 TOOLCHAIN 的位置.
這版本內部使用 64bit 的 complier , 雖然可以由環境參數設定 TARGET_TOOLS_PREFIX 的方式來解決 , 不過我的系統都是 32bit , 所以就用固定的方式吧 !

D.因為我的 uname -m 是 i686 , Compile 的時候會尋找 system/core/include/arch/linux-i686 和 system/core/include/arch/target_linux-i686 的內容 , 所以
就將 linux-x86 和 target_linux-x86 個別複製一份為 linux-i686 & target_linux-i686
C.修正 ./external/webkit/Source/WebCore/make-hash-tools.pl file.
請參考前一版 ICS 的修正方式.主要是 Fedora 16 的版本比較新 , 沒有 switch 功能.
E.Make 過程如果發現 libbfd 的問題 , 就需要更改./external/oprofile/common.mk ,
因為我們使用 i686 的 toolchain , 所以沒有 libbfd , HAVE_LIBBFD需要為 false.
更改後的 diff 如下:
---------------------------------- common.mk ----------------------------------
index f5578b1..cc79eef 100644

D.build 到 qemu 的時候會出錯
主要是 非 standalone 的時候會去 build 64bit 的 library , 這時候就出錯 !!
參考一下 Makefile.common 發現設定BUILD_STANDALONE_EMULATOR 會排除
64 bit 的 library 部份 , 先設定吧 , 到時候 qemu 要用的時候再來修正.
diff 後的 內容如下:

E.編譯到一半 會發現沒有 LIBBFD
LIBBFD 我不知道是啥東西 , 不過確定32bit 的 toolchain 沒有 , 所以修改./external/oprofile/common.mk , 這個 mk file中有指定toolchain 目錄 , 所以順便一起更改 . 只要 uname -m 是i686 就關閉 LIBBFD 和設定 32 bit 的 toolchain 位置 , diff 內容如下:

F. 編譯到 frameworks/native/libs/utils 目錄的時後會出錯
原因是會去編譯 64 bit 的 static library.
檢查一下 Android.mk file 發現 , default 會編譯 64 bit static library ,
修改成不要編譯 (使用 uname -m 區別).

目前已經可以build 完畢 , 接著要試試看有沒有問題.......
沒有想像的那樣容易 , 不能 working .
後來發現 64 bit 的系統可以跑32bit 的程式,只要安裝 所需要的 32bit library即可 ！！
舊的 Project 因為 code 的關係(int 大小不, 整個 struct 也會不對 ) 不能編譯成為 64 bit !!
不過可以在 CFLAGS & LDFLAGS 額外加上 -m32 就可以編譯成為
32 bit 的程式 , 當然對應的 32bit library 也要安裝 (ex zlib-devel.i686.....等)
乖乖的轉換 64 bit system , 並且不需要修改很多東西就可以了!!
發現 , TI release 的 Android JB for AM335x 的 BSP 了 .
一樣 在 FC16 上 build 看看吧 !! 我的 PC 還是 FC16 , 所以應該缺少的 東西不多 !
想說可以順利build 完畢 , 沒想到 .... 第一步就有問題 !!

$MY_TOOL "$@"
這一版本沒有 32bit 的 target toolchain , 所以由 ICS 的 版本內將的 toolchain
arm-linux-androideabi-4.4.x 複製到
./prebuild/linux-x86/toolchain/ 目錄下!!
原本應該在 ./prebuilds 下 , 不過擔心 ICS 的 toolchain 會有內部指定位置 , 所以放在和
ICS 一樣的 ./prebuild/ 目錄下.
本篇最後會有一個 env.sh 的 file , 內容會說明如何將 toolchain 指定到這邊 !!
B.Java VM 沒有辦法開啟 .
只細看一下 error message , 好像 jave 的 heap memory 太大 , 修正 下面這個檔案
./build/core/definitions.mk , diff 內容如下:
Error occurred during initialization of VM
Could not reserve enough space for object heap

D.build 到 qemu 的時候會出錯
主要是 非 standalone 的時候會去 build 64bit 的 library , 這時候就出錯 !!
參考一下 Makefile.common 發現設定BUILD_STANDALONE_EMULATOR 會排除
64 bit 的 library 部份 , 先設定吧 , 到時候 qemu 要用的時候再來修正.
diff 後的 內容如下:

E.編譯到一半 會發現沒有 LIBBFD
LIBBFD 我不知道是啥東西 , 不過確定32bit 的 toolchain 沒有 , 所以修改./external/oprofile/common.mk , 這個 mk file中有指定toolchain 目錄 , 所以順便一起更改 . 只要 uname -m 是i686 就關閉 LIBBFD 和設定 32 bit 的 toolchain 位置 , diff 內容如下:

F. 編譯到 frameworks/native/libs/utils 目錄的時後會出錯
原因是會去編譯 64 bit 的 static library.
檢查一下 Android.mk file 發現 , default 會編譯 64 bit static library ,
修改成不要編譯 (使用 uname -m 區別).

目前已經可以build 完畢 , 接著要試試看有沒有問題.......
沒有想像的那樣容易 , 不能 working .
後來發現 64 bit 的系統可以跑32bit 的程式,只要安裝 所需要的 32bit library即可 ！！
舊的 Project 因為 code 的關係(int 大小不, 整個 struct 也會不對 ) 不能編譯成為 64 bit !!
不過可以在 CFLAGS & LDFLAGS 額外加上 -m32 就可以編譯成為
32 bit 的程式 , 當然對應的 32bit library 也要安裝 (ex zlib-devel.i686.....等)
乖乖的轉換 64 bit system , 並且不需要修改很多東西就可以了!!

加入自己的 執行程式...
開發階段可能需要一些簡單的測試程式（執行檔) , 來進行一些小功能測試 , 所以下一個階段 , 移植一個小執行檔進入 TI BSP 吧 !!
之前我們有一個 lcd-test 的程式 , 由 console press "Enter" key , 會使用 mmap 方式填寫固定 pattern 到 fb0 內. 就先移植這個吧 !!
同樣的使用自己的 makefile 方式 .
首先開一的資料夾 ( android 的 main.mk 會自己尋找 ) , 可以有兩層 , 我的方式如下:
rowboat-android/test_apps/test/lcd-test & rowboat-android/test_apps/test/lcd-test/lcd-test-0.0.1
在 lcd-test 資料夾下放入 Android.mk file , 內容如下:

Add Busybox into TI Android BSP
開發階段 , 很多東西都在 console 下進行一些 debug 的動作 , 有些小修改 , 卻沒有 vim 可以用 , 加上有些常用的 busybox command 都沒有 , 真的有點不方便 !!
之前有 lrz/lsz 的經驗 , 這次一樣如法泡製 , 將 busybox 移植到 TI 的 BSP 中 !!
一樣借用 linaro 這個組織的東西 網址 :

之前有 lrz/lsz 的經驗 , 這次一樣如法泡製 , 將 busybox 移植到 TI 的 BSP 中 !!
一樣借用 linaro 這個組織的東西 網址 :
http://www.linaro.org/linux-on-arm
一樣修改一下 Android.mk file (格式和 debug message 修改 ) .

Add JNI demo code ( java + C )
Pure Java 完成了 , 改換 JNI 方式吧 !! 將 a + b 的動作 用 C library 來完成 .
一樣使用之前 pure java 的 code , 如下列修改方式.
private OnClickListener mAddListener = new OnClickListener()
{
@Override
public void onClick(View view)
{
int a = Integer.parseInt(mEditText1.getText().toString());
int b = Integer.parseInt(mEditText2.getText().toString());
- int result = a+b;
+ int result = addJNI(a, b);
mButton.setText(String.valueOf("A+B=" + result));
}
};
並且在 .java 中加入 :
public native int addJNI(int a, int b);
static
{
System.loadLibrary("androint-jni");
}
## 注意 library 的名稱為 libandroint-jni.so , java 會自動將 lib prefix 補上去 , 所以JNI 產生的 so file , 要注意 , 也需要 lib 這個 perfix.
接著先 產生 .class file , 在由 .class file 產生 .h , 然後 .c file include 這個 .h 並且完成 function 的功能.
產生 .class 的方式可以用下列的command :
javac -d ./ -cp /${HOME}/android-sdk-linux/platforms/android-15/android.jar src/com/eps/william/androint/AndroIntActivity.java <source top>/out/target/common/R/com/eps/william/androint/R.java
接著用 javah 來產生 .h file , command 如下:
javah -jni -classpath ../bin com.eps.william.androint.AndroIntActivity
經過測試 ,沒有問題 , 只是..... 一切都不自動 , 需要手動產生, 並且還要先編譯 java 程式 , 然後手動產生 .h file , 然後 修正 .c file , 最後在 Android.mk 中加入 .so 的 make 部份 . 一點都不優......
經過幾天的 study , 修改了一下 Android.mk 內容 , 讓整個 make 過程中自動產生 .h 然後接著 compile .c file 產生 .so ...... , 修改後的 Android.mk 如下:

Add lrz/lsz into Android source tree.
開發過程中 , 只因為修改一個小檔案 ( jni 的 .so file ) , 卻需要將 SD 從EVB 移除 , 然後放到 Fedora 上 去複製檔案 , 真的有點 "煩" !! 如果有 lrz/lsz 就好了 !!
好吧 , 移植 lrz/lsz 吧 !! Android 使用 binoic library , 和一般 cross toolchain 的 library 不同 , 並且沒有辦法執行 .configure 去產生 Makefile , Makefile 也不被Andriod Source tree 接受 , 真是大工程........ !!
找找看 , 有沒有人已經將 lrz/lsz 放到 Android 上了 !! 找了兩天..... 發現 linaro 這個組織 , 專門優化 ARM 系統的東西 , 並且在 ICS 4.0.4 上有 lrz/lsz 的 source .....嘿嘿...借來用一下吧 !! 不過也公佈一下 這個組織網頁 ... 如下:
http://www.linaro.org/linux-on-arm
按照 linaro 網頁上說明 , 將整個 source tree repo 下來 , 並將 ./externel/lrzsz 資料夾 移到 TI BSP 的相對應位置上 . 並修改 ./externel/lrzsz/Android.mk , 主要是 style 修改 , 並沒有其它改動 ,修改後如下:
LOCAL_PATH:= $(call my-dir)
lrzsz_local_comm_file := timing.c zperr.c zreadline.c crctab.c \
rbsb.c zm.c protname.c tcp.c lsyslog.c \
canit.c long-options.c xstrtol.c xstrtoul.c error.c
include $(CLEAR_VARS)
LOCAL_SRC_FILES := lrz.c $(lrzsz_local_comm_file)
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE := lrz
LOCAL_CFLAGS := -DNFGVMIN -DHAVE_CONFIG_H=1
LOCAL_SHARED_LIBRARIES := libc
include $(BUILD_EXECUTABLE)
include $(CLEAR_VARS)
LOCAL_SRC_FILES := lsz.c $(lrzsz_local_comm_file)
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE := lsz
LOCAL_CFLAGS := -DNFGVMIN -DHAVE_CONFIG_H=1
LOCAL_SHARED_LIBRARIES := libc
include $(BUILD_EXECUTABLE)
一樣的 make 過程中會編譯但是沒有安裝 , 所以修改 ./build/target/product/core.mk檔案 , 加入 lrz , lsz 兩個 packages name , 修改項目如下:
libwilhelm \
libz \
screencap \
sensorservice \
lrz\
lsz \
# host-only dependencies
ifeq ($(WITH_HOST_DALVIK),true)
PRODUCT_PACKAGES += \
OK 啦 , 可以 lrz / lsz 操作了 !! 這樣開發過程會 "爽" 一點 !!
PS. 115200 bsp 遇到大的檔案還是要花很久 , 不過至少一些 .so 或是 testing program 就可以方便多了 !!

加入自己的 demo 程式 (Pure Java )
目前 Android ICS 可以運作了 , 自己放個 Demo Code 上去跑跑看吧 ! 順便看看要怎樣加 Code 到 這個 Source Tree 上 .
本人不會 Java 語言 , 所以先找別人的 code 了 !! 剛好 .... 2010年7月有去 "仕XXX科技" ( 避免廣告用 X 代替部份名稱) 上課 , 課程內容有 java 的 demo code , 借來用一下吧 (著作權問題 , 尊重原作 , 公佈一下講師名稱: 梁文耀 ) ,這個 demo code 很簡單 , 輸入兩個數字 , 一個 button 會顯示結果.
首先 , 我不想 "污染" 原來的 Source Tree 太多 , 所以另外建立一個目錄 "Instant_apps" , 並且在這資料夾內建立一個 Instant_app.mk 檔案 , 這檔案內容只有註明增加哪些 PACKAGES, 內容如下:
PRODUCT_PACKAGES := \
Sample_1 \
在 Instant_apps 目錄下放入 sample code 資料夾 "AndroInt-ex1-activity"
在 Instant_apps/AndroInt-ex1-activity/ 建立 Android.mk file , 內容如下:
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE_TAGS := optional
LOCAL_SRC_FILES := $(call all-subdir-java-files)
LOCAL_PACKAGE_NAME := Sample_1
include $(BUILD_PACKAGE)
## 注意 , Instant_app.mk 內的Samele_1 要和這個 Android.mk 中的 LOCAL_PACKAGES_NAME 相同 , 這樣 make 過程才會正確.
這樣就可以 make 了 , 不過 最後不會安裝到 out/target/product/am335xevm/ 下 , 需要在修改一個地方.主要是說明 am335xevm target 有包含這個 demo code (如果不想預載 ,可以找到 輸出的 .apk 然後用手動的方式在 target EVB 上安裝) , 所以修改 device/ti/am335xevm/am335xevm.mk 的內容 , 如下列紅色部份
# Inherit from those products. Most specific first.
$(call inherit-product, $(SRC_TARGET_DIR)/product/full_base.mk)
$(call inherit-product, device/ti/am335xevm/device.mk)
$(call inherit-product, Instant_apps/Instant_app.mk)
PRODUCT_NAME := am335xevm
PRODUCT_DEVICE := am335xevm
大功告成 , 最後 .apk 會放在 out/target/product/am335xevm/system/app/Sample_1.apk , target EVB 開機後就可以看到 預載的 Sample code 了.
