Thread: Linux on a 8-bit processor!


http://dmitry.co/index.php?p=./04.th...ux%20on%208bit

intro

common see newbies asking in microcontroller forums if can run linux on puny little 8-bit micro. results laughter. common see, in linux forums, asked minimum specs linux are. common answer requires 32-bit architecture , mmu , @ least megabyte of ram fit kernel. project aims (and succeeds in) shatter(ing) these notions.

<snip>

how fast it?

uarm no speed demon. takes 2 hours boot bash prompt ("init=/bin/bash" kernel command line). 4 more hours boot entire ubuntu ("exec init" , login). starting x takes lot longer. effective emulated cpu speed 6.5khz, on par you'd expect emulating 32-bit cpu & mmu on measly 8-bit micro. curiously enough, once booted, system usable. can type command , reply within minute. can, in fact, use it. used day format sd card, example. not fastest, think may cheapest, slowest, simplest hand assemble, lowest part count, , lowest-end linux pc. board hand-soldered using wires, there not requirement printed circuit board.
there's video on page.

awesome! sake of awesome.

Thread: Can not create raid array: mdadm: no raid-devices specified.

hello! i'm trying setup software raid on server, fail @ first step: code: root@sandnabba:/root# mdadm -c /dev/md0 -c512 -l5 /dev/sdc1 /dev/sdd1 /dev/sde1 mdadm: no raid-devices specified. what doing wrong!? are sure -c equivalent --create? also, think need space after -c , -l options, value shouldn't command, or should have = between. @ man pages mdadm , double check spelling.

Thread: HOW TO: Package and theme GTK+ / Gtkmm apps in Linux for Windows

hi, if developing platform independent software in linux using gtk+/gtkmm , you've managed cross compile windows, guide you. i'm posting because after researching topic myself, encountered many posts people have abandoned gtk+/gtkmm wxwidgets because of gtks ugly default appearance in windows/wine. gtk+ themeable in windows/wine gnome. have set correctly . . . here's how. guide gtkmm gtk+ similar. (1) firstly, download , install gtkmm windows using wine. (you have if have cross compiled app windows) https://live.gnome.org/gtkmm/mswindows (2) run these commands create proper directory structure. (substitute 'proj' whatever project called) mkdir ~/proj mkdir ~/proj/bin mkdir ~/proj/etc mkdir ~/proj/etc/gtk-2.0 mkdir ~/proj/lib mkdir ~/proj/lib/gtk-2.0 mkdir ~/proj/lib/gtk-2.0/2.10.0 mkdir ~/proj/lib/gtk-2.0/2.10.0/engines mkdir ~/proj/share mkdir ~/proj/share/themes (3) move directory gtkmm installed (probably ~/.wine/drive
