[SOLVED] VU7 Touchscreen on Ubuntu - touch not working

Post by SwiCago »

Hi, I just got a C2 and VU7 delivered yesterday and touch seems not to be working.

I installed the latest Ubuntu on SD card as per the following link
http://odroid.com/dokuwiki/doku.php?id= ... nux_ubuntu
Installed following the wiki
http://odroid.com/dokuwiki/doku.php?id= ... hing_tools

After install was successful and I was able to SSH onto the C2, I updated the boot.ini as per
https://www.hardkernel.com/shop/odroid- ... lti-touch/
setenv m “800x480p60hz”
setenv vout_mode “dvi”

Rebooted and the display works as expect, however touch does not. I can see it get detected in the dmesg when I unplug it and plug it back in to micro-usb using cable and also the little adapter plug. Is there something I missed. I also upgraded all packages and did a dist upgrade just in case. Touch is still not working. Any help would be appreciated.

Seems also to be an issue on android
http://forum.odroid.com/viewtopic.php?f=139&t=19401

Going to see if it works on win7, to verify if it is a driver issue or defective unit.

Cheers

Update: Could not find a compliant windows driver to test...however I did a bit of digging and see the following

//Using xxd command on hiddev0 spits out lots of data, BUT ONLY WHEN TOUCH..and stops immediately when you pull your finger away

From the above xxd output, the touch seems to send stuff to the c2, but the c2 doesn't know what to do with it. I think some thing must have gotten forgotten, while compiling the C2's OS

I have a similar post with the same issue apparently. This works for me as well even though the touchscreen isn't working.

Yes, I have it connected exactly like the way you posted. As said command xxd spits out data from /dev/usb/hiddev0 as soon as I touch the screen and stops as soon as I pull my fingers away, so it is not a connection issue....it is a driver issue.

We found that the touch screen device driver was missing accidentally.
Give us a couple of days to fix and release an update. Sorry about that.

We've added the proper touchscreen driver.
https://github.com/hardkernel/linux/com ... 39d64519a3
Update the kernel to 3.14.29-35 with "apt-get dist-upgrade" and it will work.

Thanks, I am going to start from scratch...made too many small changes I cannot remember, trying to debug this issue..I'll test tonight and update thread accordingly.

EDIT: will you guys provide a new clean image with the new kernel ? Didn't see it on the ubuntu download page, like the on the Android download page.

We have no plan to release a whole image of Ubuntu in this month.

Just do below steps after fresh install.

Code: Select all

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
After reboot, your kernel version should be 3.14.29-35 or higher.

Hi, I am new in this forum (excuse me in advance for my english).
This is the first time that use Odroid to control a process in a complex machine. Everithing works fine but not the touch.
I have got 7" touch screen display with id:pid 0eef:0005 D-Wav Scientific co., ltd.
The HDMI works properly but the touch screen not!
I updeted the system with
apt-get update
apt-get upgrade
apt-get dist-upgrade
and my kernel comes to Linux 3.10.96-149 (armv7l) but touch still not works.

My OS is Ubuntu 14.04.4 LTS on ODROID C1+

Can you help me please?

Vu7 & Vu7+ should work with the C1+ Kernel 3.10.96-149.

Sorry,
Maybe this isn't the correct section.
My display is made by Eckstein with touch controller gt811.
There is a solution?
Thanks in advance

I have no idea how their touch-screen protocol works.
Each manufacturer have different controller or communication protocol and it is hard to port their driver into our Kernel.

Ask the device driver source code to your touch screen manufacturer and port it to our Kernel.

@kyearf: test the touchscreen on a linux pc. See what kernel module it uses. You could port that or try to compile it for odroid

Unresponsive touchscreen in VU7+ and the C2 in spite of all recommended updates/upgrades.

odroid@odroid64:~$ uname -a

Previous posts suggest upgrades resolved touchscreen issue. What driver would I use for the VU7+ to test with e.g. a Win or other Linux m/c to confirm it is not a defect in this specific item? This is the first time use of this specific item.

16b4:0703 is the USB ID in the Vu7+ controller.
Type "lsmod" and you will find "hid_multitouch" driver name.

BTW, please don't hijack.
Open a new thread and we will help you.
