GIT: unpack failed: error Missing tree

git push 할 경우 아래와 같은 나오면서 안되는 경우가 있었습니다.

error: unpack failed: error Missing tree 8fe84b8d352eedc3acd46a17de0531d38d5de4c2
fatal: Unpack error, check server log
To ssh://codewalker@xxxxxx.or.kr:29418/android_external_wpa_supplicant_8
! [remote rejected] HEAD -> refs/for/4412_4.4.4_master (n/a (unpacker error))

딱히 googling하여도 답을 못 찾겠더군요.

수정한 파일이 특이하게 아래 포맷으로 되어 있었습니다.
$ file android.config
android.config: ISO-8859 text

일반적으로 ASCII text인데 말이죠.
wifi_display.c: C source, ASCII text
wifi_display.h: ASCII text

그래서 파일을 지우고 다시 만들어 ASCII text로 만들고 수정하고 push 하니 문제가 없더군요.

$ file android.config
android.config: ASCII text

결론: unpack failed가 나면 file의 속성을 확인하고 ASCII text로 만들어 보자.

apk unpack and repack

기존에 누군가가 만들어준 GAppsInstaller_kk.apk가 문제가 있다는 글이 포럼에 올라 왔다.

http://forum.odroid.com/viewtopic.php?f=113&t=11854&start=50

여기서 링크에 있는 GAPPs를 사용하면 문제가 해결 된다는 글이 있다.

http://wiki.cyanogenmod.org/w/Google_Apps

그래서 GAppsInstaller_kk.apk 를 풀어 위에 아래 파일로 대체 하려고 한다.

https://goo.im/gapps/gapps-kk-20140105-signed.zip/

gapps-kk-20140105-signed.zip 압축을 푼다.

system 폴더에서 모든 파일을 선택한다.

우측 클릭 메뉴에서 Compress...를 선택한다.

gapps.tar.xz로 압축한다.

gapps.tar.xz를 gapps.xz로 변경한다.

이제 apk를 풀고 묶는 툴을 설치한다.

http://ibotpeaches.github.io/Apktool/

Apktool 2.x 버전과 Java 1.7 을 사용하였다.

http://ibotpeaches.github.io/Apktool/install/

저는 안드로이드 빌드를 위하여 1.6과 1.7 두가지 모두 설치 되어 있어서 아래와 같이 openjdk로 변경합니다.

$ sudo update-alternatives --config java

There are 3 choices for the alternative java (providing /usr/bin/java).

Selection Path Priority Status

2 /usr/lib/jvm/java-6-sun/jre/bin/java 63 manual mode
* 3 /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java 1071 manual mode

Press enter to keep the current choice[*], or type selection number:

WiringPi on ODROID-C1(Android)

ODROID-C1 Ubuntu에서 Raspberry Pi에서 사용되는 WiringPi를 사용할 수 있도록 porting 하였습니다.

http://odroid.com/dokuwiki/doku.php?id=en:c1_tinkering

wiringPi를 사용한 example-led 예제를 Android 에서도 사용할 수 있도록 작업을 해 보았습니다.

먼저 소스를 다운 받습니다.

git clone https://github.com/codewalkerster/example-led

다운 받은 소스를 eclipse에서 import 시킵니다.

그리고 NDK를 이용하여 wiringPi를 build합니다.

$ cd example-led/jni
$ ndk-build

그리고 wirinPi에서 사용해야 하는 function을 jni 형식으로 만듭니다.

jint Java_com_hardkernel_wiringpi_MainActivity_analogRead(JNIEnv* env, jobject obj, jint port) {

return analogRead(port);

}

void Java_com_hardkernel_wiringpi_MainActivity_digitalWrite(JNIEnv* env, jobject obj, jint port, jint onoff) {

digitalWrite(port, onoff);

}

int Java_com_hardkernel_wiringpi_MainActivity_wiringPiSetupSys(JNIEnv* env, jobject obj) {

wiringPiSetupSys();

return 0;

}

사용한 GPIO를 선언합니다.

private final int ledPorts[] = {

};

MainActivity에 jni function들을 선언합니다.

public native int wiringPiSetupSys();
public native int analogRead(int port);
public native void digitalWrite(int port, int onoff);

static {
System.loadLibrary("wpi_android");
}

/sys/class/gpio/export를 이용하여 GPIO sysfs 노드를 만듭니다.
sysfs 방식은 pinMode()를 사용할 수 없기 때문에 direction에 out으로 설정 합니다.
그리고 value, direction의 접근 권한을 바꿉니다.

boolean exportGPIO() {
try {
DataOutputStream os = new DataOutputStream(mProcess.getOutputStream());
for (int port: ledPorts) {
os.writeBytes("echo " + port + " > /sys/class/gpio/export\n");
os.writeBytes("chmod 666 /sys/class/gpio/gpio" + port + "/direction\n");
os.writeBytes("echo out > /sys/class/gpio/gpio" + port + "/direction\n");
os.writeBytes("chmod 666 /sys/class/gpio/gpio" + port + "/value\n");
}
os.flush();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
return false;
}

return true;
}

wiringPi의 "/dev/mem"을 open 하여 mmap을 사용하는 방식으로 만들려고 하였으니 "/dev/mem"은 root가 아니면 접근을 제한하도록 되어 있어서 불가능합니다.
jni의 library에는 root 권한을 줄 방법이 없습니다.

그래서 wiringPiSetupSys()를 호출 하여 wiringPi library를 초기화 합니다.

주기적으로 update()를 호출 하도록 만들고 UI와 LED를 control 합니다.

public void update() {
int i = 0;
int adcValue = 0;
int ledPos = 0;
if ((adcValue = analogRead (PORT_ADC1)) > 0) {
ledPos = (adcValue * ledPorts.length * 1000) / 1024;
ledPos = (ledPorts.length - (ledPos / 1000));
mADC.setProgress(adcValue);
} else
ledPos = 0;

for (i = 0; i < ledPorts.length; i++) {
digitalWrite (ledPorts[i], 0);
mLeds.get(i).setChecked(false);
}

for (i = 0; i < ledPos; i++) {
digitalWrite (ledPorts[i], 1);
mLeds.get(i).setChecked(true);
}

if (!mStop)
handler.postDelayed(runnable, 100);
}
