So the Beaglebone uses the file uEnv.txt to store settings as it doesn't have any NAND allocated to do it with, by 
default the file is pretty empty save from the line:

optargs=run_hardware_tests quiet

You may have read a number of things about boot.scr etc  - ignore it, it's not correct.
The bootcmd is hardwired in uboot to do the following (i've seperated it all out to make things clearer) - you can see it by 
interrupting the bootsequence and performing a 'printenv'.

bootcmd=

###QtCreator Remote Development And Deployment with SDK

####Install On Ubuntu 15.04's PPA has an outdated version of QtCreator (3.1.1). Remote deploy and debug do not work with the version of QT5 included in meta-qt5 (qt5.4.3). Instead, we will use an up-to-date version from Qt.io.The web installer from qt.io (https://www.qt.io/download/) lets you pick the version of QTCreator (3.4.2 in this case) you want. The binary of the web installer is named qt-unified-linux-x64-online.run for a system running 64bit Ubuntu 14.04. Download the installer suitable for your workstation. The installer lets you pick the version of QT5. Make sure to choose Qt5.4 to match with meta-qt5. Also note that you will have to create an account for Qt to install.

####Configuration We will configure QtCreator with

Enabling SGX (hardware accelerated graphics) on Pepper SBC is straight forward with Gumstix Yocto Project. Note that SGX does not support X11.

The custom, SGX enabled, image builds on the development branch of the Gumstix Yocto Project. A couple things need to be modified to add TI's Graphics SDK (v5) and Qt5-SGX demo applications. So be sure to set up the Yocto Project build environment first. Note that you need the development branch. The master branch has not been updated with necessary kernel patches.

Now you can make necessary changes to add SGX, build an image, and boot your device:

1. Uncomment these lines from local.conf located in build/conf/:

   # Specify SGX GFX providers for Pepper
   PREFERRED_PROVIDER_virt
