Android on 7 inch raspberry pi official touchscreen display

[Vishruth]

Hey guys , I'm trying to make an android tablet using raspberry pi 3. I have a 7 inch touchscreen display. I have downloaded the image from youtube tutorials for nougat and marshmallow. But it happens to run only on HDMi TV and not on Touchscreen display which uses the DSI port of raspberry pi. 

IT would be helpful of you if someone could send me a link to download the image for android which is compatible with the touch display. Or if I should change some settings in the kernel modules of OS do tell me.

Thank you

[Igor Kalkov]

We do have a working version (the attached image is made today). But it requires a lot of changes to system files after the installation.

In a couple of days we will release a script to setup a video resolution after installation.

Hi Igor, just in case, arent you working or planning to work on reading wiegand protocol to android thing?

[olivierdes...@gmail.com]

Great news! Is it usable everyday or is it too slow and buggy?

[Igor Kalkov]

No, we are not working on that.

[mathew.a...@gmail.com]

Has the scripts been released yet?

[Igor Kalkov]

The beta version of the script was pushed to github a couple of hours ago. It will be automatically included into the tomorrow's build.

The script uses a new initialization method in RTAndroid, so it will probably only work with the latest release. We didn't test it with old releases though.

[mathew.a...@gmail.com]

Great! I've installed it on the RPI3! A bit of flickering at start, But seems to be working just fine after the initial install. Good work!!!

[Steve Fleck]

Hi Igor!

Great work. 

I was wondering which script I needed to try loading to the Pi3 B w/official touchscreen?

Thanks!

[Igor Kalkov]

Please download the latest release, install and run:

./video.sh -c raspberry-7inch-touchscreen /dev/DEVICE

[xer...@googlemail.com]

When I try to use this command, he wants to chose one of the two configrations... any idea ? ( its: ./video.sh -c raspberry-7inch-touchscreen -a arm -i myip), thanks

[Igor Kalkov]

Please read my post again. There are no "-a -i" options available in the video script.

[xer...@googlemail.com]

Ye, i figured it out, sorry for that stupid question, it works now :).

[Marcel Beckers]

Where can i download this working image?

[Igor Kalkov]

What image?

[luoyo...@gmail.com]

Where is the corresponding script & RTAndroid image file?

[Igor Kalkov]

The video script is included into the RTAndroid zip package.

[罗勇刚(Yonggang Luo)]

Do I need  to specify any parameter to the video script?

 with the latest image rtandroid-aosp-7.1-20170208 the video.sh script for the raspberry display stops with errors. Nevertheless it works after that, so maybe it is only a small problem. The error(s):

the command:
sudo ./video.sh -c raspberry-7inch-touchscreen /dev/sdb

the log:

Maybe you can have a short look.

[Igor Kalkov]

Thanks for reporting, Frank. Should be fixed now.

For testing please re-install (one of your files was changed) and re-run the video script. It will automatically pull the latest version.

[lampen...@gmail.com]

Thanks for the fast fix Igor, it works.

Perhaps you used the wrong -p or --strip option?

Your installation seems to be wrong:

mount: /dev/sdb2 is not a block device (maybe try `-o loop'?)

You didn't have this problem in your latest log. Please reinstall and try again, if the installation goes fine. 

[ruck...@gmail.com]

The script works fine. Great job!

Do you have any ideas on how to rotate screen by 180º?

[Diskio Pi]

Do you have any ideas on how to rotate screen by 180º?

Hi, you want maybe set the config.txt with this parameter:

display_rotate=2 

[Thomas Ruckstuhl]

I set the parameter in config.txt but it is still upside down. Except this little issue the screen does work perfectly. I'm wondering why they manufactured the frame for the official screen the wrong way...

cat config.txt:

hdmi_force_hotplug=1
hdmi_drive=2
hdmi_group=2
hdmi_mode=87
hdmi_cvt=800 480 60 6 0 0 0
kernel=zImage

dtparam=audio=on
dtparam=i2c1=on
dtparam=i2c_arm=on
dtoverlay=vc4-kms-v3d,cma-256
dtoverlay=i2c-rtc,ds3231

initramfs ramdisk.img 0x01f00000
mask_gpu_interrupt0=0x400
avoid_warnings=2
gpu_mem=256
enable_uart=1
display_rotate=2

Do you have any other ideas?

[Igor Kalkov]

Can you use an existing application for this? Something from Google Play Store?

Thank you for showing me the right direction. With "lcd_rotate=2" it works perfectly.

[Frans Thamura]

can we use the waveshare's LCD that connect to the gpio of raspi3

we have the 2.4, 3.5" piscreen

thx

[Igor Kalkov]

Didn't try it myself. My waveschare HDMI LCD 7" works fine.

[Igor Kalkov]

You need either "curl" binary. Can you install it on Debian? I'm using Ubuntu and it seems to be preinstalled.

[soap...@gmail.com]

Hello Igor,

I tested today, but I have the issue with download driver like zumpan... .
I used Ubuntu Desktop. Can you scribed me this curl in binary and where in video.sh row I get it.
Thanks
PS: Im totally beginer please be quiet.

You don't need any additional files on Ubuntu. Everything should be included into the zip package.

[soap...@gmail.com]

OK, you have true.
The Issue is not installed Ubuntu, run only from usb.
Than I installed curl - driver was updated.
Like I scribed - Im beginer who learn by walk.

I installed Android 7 from here: https://rtandroid.embedded.rwth-aachen.de/downloads/raspberry-pi/, on a 5 inch waveshare: http://www.waveshare.com/wiki/5inch_HDMI_LCD#Screen_orientation_settings

Changed the config file's default dtoverlay to: dtoverlay=vc4-fkms-v3d,cma-256

initramfs ramdisk.img 0x01f00000

instead of: dtoverlay=vc4-kms-v3d,cma-256

initramfs ramdisk.img 0x01f00000

The android operating system fits the screen perfect but there is no touch.  Is there any way to change this?

Thank you,

Andy

[Igor Kalkov]

How is it connected? My 7" screen is connected via HDMI, but requires an additional USB cable for touch.

[nevetzede...@gmail.com]

Hello,

Do you mean that using the RPI 3 and the 7" touch screen you can install Android and manage the touch by an additional USB connection?

BR,

Remi

Igor, thanks for all this great work and looking forward to these features.  I have image installed and it loaded perfect except resolution.   I have official 7 inch touch.   Where do I execute this command?  I only see the top left corner of the screen on my android touchscreen.    Only the left 9 icons.   I do not see a console or anywhere to input this command.  Is there something I can hold at boot to enter a console?
 

./video.sh -c raspberry-7inch-touchscreen /dev/DEVICE

  Please help direct me and possibly others where we need to type this to correct the resolution.    

[betocua...@gmail.com]

Hi, is it possible to configure the resolution for official lcd raspberry with rtandroid installed?

Hey ragazzi, sto cercando di fare una compressa androide utilizzando il lampone pi 3. Ho un display touchscreen da 7 pollici. Ho scaricato l'immagine da tutorial youtube per torrone e marshmallow. Ma succede che si esegua solo su HDMi TV e non sul display touchscreen che utilizza la porta DSI di lampone pi. 

IT sarebbe utile se qualcuno mi potesse inviare un link per scaricare l'immagine per Android che è compatibile con il touch screen. O se dovrei cambiare alcune impostazioni nei moduli del kernel di OS mi dica.

Grazie

[Igor Kalkov]

You don't need any scripts for emteria. The official touchscreen is working out-of-the-box.

[se...@chillhitlabs.com]

Hi, I have a weird issue. The display only outputs console data to the 7 inch touch screen. The GUI for Android only outputs to the HDMI port.
So unless I plug in an HDMI screen I cannot see the GUI.

[Vishal Shukla]

HI All,

Hey, I was wondering if you have an active link for this download
