Adding apps on embedded Linux
I'm not exactly a Linux newbie but I have bought a cheap Chinese Ebook E-reader which I believe runs on embedded Linux, of which I have no experience. It has a reasonable music player but I want to turn it into a convincing looking Jukebox, but I don't know where to start.
Limited information available -
8gb storage plus sd card reader, mini usb port,DC power socket, headphone socket. Touch sensitive screen.
Manufacturer - Rockchip
Major version 0.0.2
Anyone any suggestions as to if this is possible and where to start? Many thanks.
