6. Software / Driver Disclaimer
4D Systems has developed this 4DCAPE-70T CAPE for the Beaglebone Black, and is based on hardware already
present in the market. 4D Systems does NOT support any software associated with the BBB nor software and
drivers associated with this CAPE. It is up to the user to determine which software is used on the BBB and which
distributions are used on the BBB, and therefore which are compatible with this CAPE.
4D Systems has been made aware that there may be touch related issues with the Angstrom Distribution
(Possibly others if based on the same issue source) of Linux, and the mouse may appear to ‘self touch’ or jump
around the screen on touch, or generally behave erratically. Since 4D Systems has not developed nor supports
anything to do with the software associated with this hardware, 4D Systems is unable to assist or offer support
regarding this matter. ** A Fixed Kernel is now available, 3.8.13-bone37 while solves this issue **
The Android distribution listed in this document does not feature this erratic touch behaviour and effectively
illustrates the issues are software or driver related, and not hardware.
If these issues are encountered, it is encouraged to try the Android distribution to verify it is not a hardware
issue. If the issue remains, please contact the 4D Systems Technical Support. If the issue is no longer present and
touch works correctly on Android, then please contact the beaglebone.org community.
The 4DCAPE-70T utilises drivers which have been written for other devices on the market and the hardware is
set up in a similar fashion. Drivers for the Circuitco LCD7 are utilised for this CAPE and therefore if fixes are made
to improve compatibility with the LCD4, they should also function correctly for the 4DCAPE-70T.
4D Systems is not responsible for issues regarding software or drivers associated with the BBB and the
compatibility with this product. Only Community software support is allowed via resources at
