i've been thinking mini2440/ubuntu combo myself. mini2440 seems worlds better (and cheaper) beagleboard seems playing with.

anyway, can tell, patches mini2440 included in linux kernel version 2.6.31 while ubuntu 9.04 looks based upon 2.6.28.

may matter of waiting until ubuntu catches kernel versions include support mini2440, i'm guessing.

it's been years since i've looked @ linux, i've been contemplating embedded pc projects guess i'll have bite bullet , re-educated...

hello ! wrote today article on blog cpu load monitoring (using gpio , leds) on raspberry's. simple (written in little shell script), think can useful (for people want learn leds stuff on r. pi) there 5 leds turning on , off regarding cpu load: - cpu < 20%: 1 led - cpu < 40%: 2 leds - cpu < 60%: 3 leds - cpu < 80%: 4 leds - cpu < 90%: 5/5 leds - cpu >= 90%: 5 leds flashing here article: written in french, can watch youtube video , download code @ bottom of article. http://www.chteuchteu.com/2012/10/26/ra ... e-au-gpio/ if find errors in code, can post comment on article. ! up code enhancements ? raspberrypi
