Can I build or get Android 4.2 or lower image on the Riotboard?

kenhsu Jul 10, 2014 4:23 AM

Dear John McLellan,

Something trouble on my USB 3G dongle's installation. If I want to build to get the Android 4.2 or lower, that should be OK?

Sincerely

Ken

you can build android from source for Riot
refer this blog by otto.

You can follow the instructions in my blog like tusharp said.

But If you want to compile Android 4.2 you have to change the manifest when checking out the files with repo.

Instead of "-m embest_android_jb4.3_1.0.0" you´d have to use "-m embest_android_jb4.2.2_1.1.0".

But I don´t think that compiling Android 4.2 alone will get your USB 3G dongle working. You´d have to integrate the right driver and then compile.

the USB 3g needs to have supported drivers either in kernel or in android userspace to get it working.

  Dear Tushar Panda,
  
  I used PPP Widget to try to connect to 3G and plug USB dongle to get these message from console as below, PPP Widget always show "No modem found".
  
  ehci_fsl_bus_suspend begins, Host 1
  ehci_fsl_bus_suspend ends, Host 1
  ehci_fsl_bus_resume begins, Host 1
  ehci_fsl_bus_resume ends, Host 1

  scsi8 : usb-storage 2-1.2:1.0
  usb 2-1.2: USB disconnect, device number 7
  usb 2-1.2: new full speed USB device number 8 using fsl-ehci

  option 2-1.2:1.1: GSM modem (1-port) converter detected

  scsi11 : usb-storage 2-1.2:1.2
  scsi 11:0:0:0: CD-ROM HUAWEI Mass Storage 2.31 PQ: 0 ANSI: 2
  
  Then I checked PPP Widget website and found
  
  Attention: Android 4.3 has changed the kernel so that loading driver modules is disabled. Nexus 7 Old still has modem drivers enabled in the kernel, but Nexus 7 New (Wifi) and Nexus 10 don't. Since there is no more way to add drivers, USB modems cannot be used with these devices anymore. Blame Google for this.
  
  This topic is gotten from http://www.draisberghof.de/android/pppwidget.html
  
  If I use Android 4.3, I can bind another module to solve this issue or build Android 4.2 or lower?
  
  Sincerely
  Ken

    loading driver modules is disabled
    
    They don't permit userspace drivers.
    so you need to recompile kernel and bind the module with the appropriate drivers (y option) to get your dongle working.

    once plugged in detect the VID:PID by lsusb.
    with VID:PID you can search for any existing drivers.

  I mean you need to build the kernel with supported drivers (either vendor provided or available in open source) to get the device up.
  once the device is up, then maybe (as author claims) the widget will be able to detect it.
  
  can't say if it will solve the issue or not , but definitely the drivers will provide hardware interface , just need to hookup with a supported app.

    Just fyi.
    
    I tried checking out the Android 4.2.2 source. But the manifest file seems to be broken.
    I only get errors when I try.
    
    I´ll look further into it but only when I have time again.

        There is no Tarball of the source code.
        You have a manifest xml file that describes where to download the source.
        You find both for Android 4.2.2 and 4.3 here: https://github.com/embest-tech/imx-manifest
        
        To use it you need a tool called repo.
        Everything for getting and compiling the source in Debian is in my description here: Building Android from Source
        
        Also the manifest file for Android 4.2.2 is broken it seems. Android 4.3 is working though.
        Didn´t have time to look into it by now.

        In Ubuntu you don´t have that parameter in dpkg.
        
        Normally you don´t need to add it. Because with the :i386 when installing the packages with apt it should install the correct versions.
        
        To add i386 to dpkg you´ll have tot do it manually like this.
        
        sh -c "echo 'foreign-architecture i386' > /etc/dpkg/dpkg.cfg.d/multiarch"

    It seems there is something with the encoding or anything with the chars when copying from the website.
    I can´t tell what it is...
    
    Edit: I corrected the String in the Blogtext. Now you should be able to copy and insert it.
    There was an error in conversion from ANSI to UTF8. (Which most of the SSH shells use...)

        You´re using 16 Threads with the parameter -j16.
        Maybe the virtual machine has some issues with that many threads.
        
        I don´t know how many cores your virtual machine has associated, but try to reduce it to something like 4 or remove it completely.
        
        Otherwise I wouldn´t know of any restrictions that a virtual machine couldn´t get the code aswell as a host.

Maybe correct, and I re-install my Android12.04 from Chinese version to English.

  Yeah if your Ubuntu is 32bit it won´t work.
  You NEED a 64bit version. The compiler is made for 64 bit, because compiling Android needs a lot of RAM.
  
  If you´ll install a new Version as a Virtual machine, I´d advise to use a Debian 7.5 64bit.
  I tested it with that. With Ubuntu I didn´t test it. (Don´t like Ubuntu... ) Although I can´t say it won´t work.

      If you look here: https://github.com/embest-tech/imx-manifest
      You´ll see that there are two manifest files.
      The one with Android 4.3 is used when doing the repo init with the parameter "-m embest_android_jb4.3_1.0.0".
      
      Theoretically you should only change this parameter to "-m embest_android_jb4.2.2_1.1.0".
      
      But...
      
      As I tested that it won´t work. First it won´t download the manifest file. So I did a init with 4.3 and replaced the manifest.xml in the hidden ".init" folder.
      But then I only get errors on sync.
      
      Seems the manifest file itself is somewhat broken.
      
      If you manage to get it run let me know. I don´t have time looking into it.
      Maybe someone else can look into it too...

  I corrected the manifest file.
  
  Although the sync is still running (takes some time as always) it looks as if it runs through.
  
  Also I can´t tell if there has to be done further tweaking like in the 4.3 Version.
  
  You have to do the following:
  
  Do the normal init with 4.3.
  Then unzip and copy the file I posted into the .repo folder and overwrite the old one.
  (Since xml files aren´t allowed to post here I uploaded a zip. Don´t know if you get a zip in a zip like this...)
  
  (Download the file here: http://radisserver.ddns.net/riotboard/Android/manifest.xml
  This Website is successfully preventing me from uploading the file...)
  
  And then just do the normal repo sync.
  
  Still can´t promise that it´s working as it´s still running.

    An update to this:
    
    The configuration for the riotboard is not integrated.
    So there has to be done much more till you can use it.
    
    I think it would be easier to integrate the drivers you need into 4.3, rather than trying to get 4.2 working.

      I didn't completely understand your descriptions.
      
      I already setup and built Android 4.3 images on Utbuntu 12.04.
      
      I need to run these commands and ...
      
      repo init --repo-url=git://github.com/android/tools_repo.git -u git://github.com/embest-tech/imx-manifest.git -m embest_android_jb4.2.2_1.1.0

        To get the Android 4.2.2 source you have to do an init with 4.3.
        
        This:
        
        repo init --repo-url=git://github.com/android/tools_repo.git -u git://github.com/embest-tech/imx-manifest.git -m embest_android_jb4.3_1.0.0
        
        And then replace the manifest.xml file in the hidden .repo folder with the one I linked at.
        
        But that won´t help you much. Because you can´t compile it for the riotboard. There is no configuration for it.
        Only vor ARMv7 Neon CPUs. That won´t work.
        
        So just stick with the 4.3 version and try to get the drivers working.
        As Tusharp already said: With the device connected and with the command lsusb get the Vendor and Device ID.
        With that you know which drivers you´ll need.

Before I build image, can I set a command(like make menuconfig) to modify the bind the modules?

  You have to cd into the kernel folder. Then you can execute make menuconfig for the kernel.
  
  Being in the Android Source folder:
  cd kernel_imx make menuconfig
  
  Then the created .config file has to be copied into the standard config file for android imx6.
  
  cp .config arch/arm/configs/imx6_android_defconfig
  
  After that you can normally build Android.

You mean I can check the config file from arch/arm/configs/imx6_android_defconfig, am I right?
If so, why I can check the "GSM and CDMA" item.

from make menuconfig

Device Drivers->USB support->USB Serial Coverter support->USB driver for GSM and CDMA modems.

normally build Android: back to riot_source folder, then make -j8, right?

I check marketing Android 4.3, the package kernel is 3.4. and I check Riotboard is kernel 3.0 for Android 4.3. That means I mention PPP connect issue before

Attention: Android 4.3 has changed the kernel so that loading driver modules is disabled. Nexus 7 Old still has modem drivers enabled in the kernel, but Nexus 7 New (Wifi) and Nexus 10 don't. Since there is no more way to add drivers, USB modems cannot be used with these devices anymore. Blame Google for this.

That have not this issue for our Riotboard 4.3, am I right?
Sincerely
Ken

  You mean I can check the config file from arch/arm/configs/imx6_android_defconfig, am I right?
  
  If so, why I can check the "GSM and CDMA" item.
  
  from make menuconfig
  
  Device Drivers->USB support->USB Serial Coverter support->USB driver for GSM and CDMA modems.
  
  Don´t understand the question. Why shouldn´t you be able to check that item?
  make menuconfig reads the ".config" file in the "kernel_imx" folder. Not the one in "arch/arm/configs".
  Also the config doesn´t say what you CAN check/select or not, but what IS checked/selected. The config is used to build the Kernel with it´s settings.
  
  normally build Android: back to riot_source folder, then make -j8, right?
  
  Yes that´s right. But you may have to execute lunch before compiling with make.

  Checked that right now. Yes that´s also true the Android 4.3 Image for the RIoTBoard uses the old Kernel 3.0.35.

cp .config arch/arm/configs/imx6_android_defconfig

Just check from your last response command and make sure "USB driver for GSM and CDMA modems" already is set on config file.

If I only modify a file, built time can be shortened. Every time I built image took more than 2 hours.

  That´s because it´s already configured in the original "arch/arm/configs/imx6_android_defconfig" I suppose.
  
  When you execute lunch and select the riotboard, this config is copied into the .config in the kernel_imx folder which is read from make menuconfig.
  That´s why you have to copy your new config if you made any changes into "arch/arm/configs/imx6_android_defconfig".
  
  Then when you execute lunch, you have the changes you made in the .config for compiling the kernel.
  
  The option "USB driver for GSM and CDMA modems" is already set in "imx6_android_defconfig".

  You can compile the kernel alone and then just build the image files like this:
  
  cd kernel_imx
  make clean
  make -j4
  cd ..
  make bootimage
  
  You´ll need the arm-fsl-linux-gnueabi-gcc compiler for this.
  
  Tip comes from mukelarvin_price and his blog

    Where is his blog?
    
    I follow your rule to generate 3 images(boot.img, recovery.img and ststem.img), didn't generate u-boot-mx6sol...bin.
    and I download to Riotboard, but I cannot root. Using the method build images, can be affected on root process?

      Just search for his name then you´ll find everything he´s written.
      
      If you don´t have an u-boot image file, then you made something somewhere wrong. Compiling the whole system after you selected the riotboard in lunch, should create all files as well as u-boot.
      
      I tested rooting with the compiled Android 4.3 image you created (Both -user and -eng builds). And since the manifest has been changed the last time 4 months ago, I assume that it´s still working.

Re: Can I build or get Android 4.2 or lower image on the Riotboard?

kenhsu Jul 28, 2014 5:15 AM (in response to kenhsu)

root is OK.

Where can I double check the config USB driver for GSM and CDMA modems item? or I need to set other items on config.

Both of 2 devices are root. The same procedure from the OS image beginning. I used in the Android 4.0 for tablet, PPP widget connect is OK, but on Riotboard Android 4.3, I plug in USB 3G dongle, the PPP widget always isn't response and show "No modem found". On the console debug can see "GSM modem (1-port) converter now attached to ttyUSB0". I don't what differences are 2 devices?

Sincerely
Ken

  Your Stick is correctly recognized and is reachable through ttyUSB0.
  
  You have to ask the developer of this app what it´s expecting to get.
  This is nothing we can help you with.
  
  At least there´s a forum for this app.
  USB_ModeSwitch • View forum - PPP Widget for Android

      I´m glad it´s working.
      
      But again please mark your questions as answered.

After I modified original config file, the generated image cannot start up on Android windows. I forgot what items I modify on "make menuconfig". Where can I get the original config file?

Sincerely

  Here is the file: imx6_android_defconfig
  
  But you could also delete the file and then do a repo sync.
  Just takes some time until all files are checked, and there are a lot as you know.

      I´m currently having problems with my server.
      (After a reboot it´s not coming back. Not even a ping.)
      I´m working on that right now.
      
      So to get the default config right now, just delete it and make a repo sync.

      Had a problem with the network configuration. (Though I didn´t change anything...)
      
      But the Server is now back up and the files are reachable again.

        This config file is not original file. HID and WiFi(Usb Wi-Pi dongle( are not start up.

        I just checked the file.
        It IS the file that´s coming with checking out the code.
        
        There is no guarantee that the file you get from the code is the same that has been used to create the image.
