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.

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

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.

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.

Sorry, currently I cannot attach to imx6_android_defconfig

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.

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?

I´m glad it´s working.

But again please mark your questions as answered.

We have a lot of questions that are still not marked as answered right now.

Thanks for your information.

The problem is solved.

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

Also please mark your questions as answered.

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?

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.

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?

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

Can I shorten the built time? Every time I built the images took more than 2 hours.

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

radiatortwo — Fri, 25 Jul 2014 08:43:28 GMT

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".

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

e14 Contributor — Fri, 25 Jul 2014 08:34:40 GMT

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.

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.

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?

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

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.

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

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.

e14 Contributor — Tue, 22 Jul 2014 02:11:56 GMT

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

repo sync -j16

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.

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

radiatortwo — Mon, 21 Jul 2014 18:02:30 GMT

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.
