Hi
With the factory flashed eMMC image , the 4DCape-70T was detected on boot up, and a calibration screen was launched before the GUI. This calibration application included a countdown timer , shown using a animated color circle in the middle of the screen. Everything worked nicely on a quick test.
Using http://elinux.org/Beagleboard:BeagleBoneBlack_Debian, I used a 8Gb uSD card to flash the jessie debian testing image from 2015-1-27 to get access to qtcreator (for qt 5) via apt-get. [ https://rcn-ee.net/rootfs/bb.org/testing/2015-01-27/lxqt-4gb/BBB-eMMC-flasher-debian-jessie-lxqt-4gb-armhf-2015-01-27-4gb.img.xz ]
The 4DCape-70T didnt work on boot up, but required adding in a dtb=am335x-boneblack-4dcape-70t.dtb line in /boot/uEnv.txt and rebooting. The LCD cape works for display, but the calibration application wasn’t installed.
I did install a “libts-bin” from wheezy , and can run ts_calibrate, but this isn’t the same version (or maybe not even the same program) as above. It looked partially the same, but for instance had no timer, counting down. I presume that the timer was added, because it was added into the boot-up sequence. However, even with the version of ts_calibrate it still is very badly calibrated, with the boundary areas inaccessible, and has ghost input / skipping the cursor around the screen.
Any hints how to get back to the calibration program via the factory flashed version of Debian? I can offer to port it to Debian testing BBB image. 
Less important, since i can patch around it, but what changed between the (presumably) Wheezy image and jessie image, so that the cape isn’t automatically available anymore?
Cheers cuz,
Andy

Don't use libts-bin, use xinput-calbrator (which is already installed)..
However i haven't wired it up the lightdm "yet"
Priority right now is to ship the last "wheezy" stable release..
Before i focus entirely on jessie.

Well, downgrade to:
sudo apt-get install linux-image-3.8.13-bone70
and your cape will be autodetected..

Ok, yes xinput_calibrator works. Thanks mate.

I am sticking to 3.14.30-ti-r47 and testing repo , thanks 
Everything is working nicely for QT5 development. qtcreator 3.2.1 / qt5.3.2 installed via apt-get all work.
QT Creator wasn’t auto configured properly, but it was possible to get it to work manually configuring the ‘kit’ via (Tools->Options) setting the qt versions and compilers.
Very nice work to all involved!
