AM335X Android Porting.....

2013年5月2日星期四

Andorid HAL & system service testing / example code for TI AM335xevm JB BSP.

A. APP . "AndroInt_ext8_native"
We start from the demo apk. This apk is very simple , create two text input , and one button. Input the number at text_1 & text_2 , the button click will adding two numbers from each text, and show result on text of Button.

The IAndroIntServie is java interface , create by .aidl file in frameworks direct.
In this interface only have one function "AndroInt_add()".

So this using ServiceManage.getServie() to get system service.
This Service will implemnet in frameworks .

Now we go through to next step " modify frameworks ".

3.Implement AndroIntService.java file.
   In this class , implement AndroInt_add(); function and
   addService "androint" into system service.
   In AndroInt_add() function , we call JNI function add_native().
   The add_native() will access kernel driver.

   add service "androint" into system service.

   There have two JNI function.

   add_native(): write data into kernle char driver. And do add in kernel driver,
   then read result from kernel char driver.

   init_native(): get HAL module device data , and open kernel char device.

2. Modify am335xevm_sd.mk file .
    Add androin.$(TARGET_PRODUCE) .
    ### importent ###
       androin.$(TARGET_PRODUCE) .
       must same as HARDWARE_MODULE_ID

   the HAL hw_get_module() will searce /system/lib/hw/ <id.product.board>
   the id is HARDWARE_MODULE_ID.

2013年3月22日星期五

Build TI-Android-JB-4.1.2_AM335x_4.0.1 BSP in x64 Fedora 18

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"

    PATH1=`echo ${PATH} | sed "s|[:]${TOOLCHAIN_BIN}||g" | sed "s|${TOOLCHAIN_BIN}[:]||g"`
    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.

E. Build kernel 過程中會發現少了mkimag file .
    這個 utility 是由 u-boot 產生 , 所以修改一下 ./Makefile , 讓 u-boot 在 build kernel 之前會先 build 出來, 並且會將 mkimage 複製到下 ./build/ .

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:

Could not reserve enough space for object heap

~~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 ,~~

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!!

2012年9月18日星期二

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:

主要將一些 ldflags , cflags export 到下一層 Makefile 使用 , 其中 EXE_EXT_FILES 是因為執行檔 , 會需要這兩個 .o file , 並且很奇怪需要放在同一個目錄下 , 我試過使用 --sysroot=<path> 的方式 , 也是不行 , 所以只好 copy 過去 make 完畢後 delete 掉.

接著在 ./lcd-test-0.0.1/ 下建立 Makefile , 這個 makefile 就是自己的方式.內容如下:

# ./test_apps/test/lcd-test/lcd-test-0.0.1/Makefile
#
# vi: set ts=4 :

build 完畢後 ,利用 lrz 傳到 EVB 上的 /system/bin/ 下 . 執行看看 !!
成功....... ^^ , 不過會被原本的畫面 re-flash 掉 , 所以建議找畫面更新率最低的頁面測試 , 或是使用 stop command 讓 java machine 暫停 , 在利用 console 執行測試程式.

Android 的 fb0 位置和一般linux 不同 , 移動到 /dev/graphics/fb0 位置.

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 :

http://www.linaro.org/linux-on-arm

一樣修改一下 Android.mk file (格式和 debug message 修改 ) .

最後可以在 out/target/product/am335xevm/system/bin/ 下看到 busybox 和一些 command 的 link .... 大功告成 ..

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:
