i mean.. im just starting out with linux (both for my desktop and my mini2440) and i saw the led blinking commands that you enter through the serial shell.. if there were some examples of how to achieve all 4 leds lighting up on different things, say one lighting up by a key press, another lighting up by a touch on the screen and the remaining two blinking at two different speeds.
and another thing.. can i get a shell prompt on the screen of my mini2440 and then connect a usb keyboard and enter the commands directly on the mini2440? that would be really awesome!! if you could just point me in the right direction.. :) and last thing.. i'm planning to write a series of tutorials on the bsp and its setup and some simple usage application for complete n00bs to linux (like me!). i hope that's alright..
