Thanks for the reply. Ideally I would like to run linux in a non-android environment. Are there instructions as to how to install the openembedded images on the board? Will I need a UART for that?
As for the second link, do you know of any su binaries which I can use to give the root privileges to the app? Are there any techniques to "root" the board so that the apps can have privileged access?
The third link looks good and I would like to use that as the final option. Ultimately I want a linux distro which does not run in android and also does not require UART for installation.
