Hi,
Apologies for appearing dumb but after wasting time I need assistance.

CircuitCo LCD7 I've got working well using:
uname -a
Linux beaglebone 3.8.13 #1 SMP Thu Feb 6 16:19:16 CET 2014 armv7l GNU/Linux
lsb_release -a
Distributor ID: Angstrom
Description:    Angstrom GNU/Linux v2013.06 (Core edition)
Release:        v2013.06
Codename:       Core edition

However - For the death of me - I cannot install headers in order to build driver for wifi dongle using driver RTL8192EU. Seems to me headers are not supported on Angstrom anymore?

Also tried Debian on Element14 BBView - causes mouse jitter - or earlier debian can't get SSH when BBView cape is attached.

So - what I want to achieve is a working LCD and linux-headers installed so I can build the RTL8192EU driver. Then I want to create QT applications to run on the LCD, Many thanks in advanced for your assistance.

Paul.

Angstrom died back in 2013.

Jitter "should" be fixed via:

https://github.com/RobertCNelson/ti-linux-kernel-dev/commit/589afe517cb1bbedb5faa67cb60ec059f20634e5

4.4.62-ti-r101+ kernel's..

use the July snapshot,
https://rcn-ee.net/rootfs/bb.org/testing/2017-07-01/lxqt-4gb/

for the BBView, there's no eeprom, so when using u-boot overlays you
will have to force the overlay:

Hello Robert.
I'm trying to understand what to do to solve the BBB touchscreen jitter problem.
Sorry if my question is dumb, but i'm a Windows user/programmer and the linux "way" to compile / patch / solve problems is hard to grasp.

Are newer images in https://rcn-ee.net/rootfs/bb.org/testing/ "patched" as well, or only the one you linked?
The link for the July snapshot (https://rcn-ee.net/rootfs/bb.org/testing/2017-07-01/lxqt-4gb/) is broken. The closest one is https://rcn-ee.net/rootfs/bb.org/testing/2017-07-02/stretch-lxqt/ .

So, in the end, by downloading the right image should i have the jitter problem fixed?
