The Linux distribution for NDS is called DSLinux and is under active development. To run it, use the following procedure:
- Connect the DSX to the USB.
- Download http://kineox.free.fr/DS/dslinux.nds and put it in the "apps/" folder. This version has wireless support.
- Since the DSX own application launcher are unable to launch DSLinux for some reason, another launcher has to load Linux. The launcher DSChannel can do the work. Unpack http://gtamp.com/DS/dschannels_beta5b_DS-X.7z to the root of your DSX.
- From DSX, start DSChannel. From DSChannel start DSLinux. If you try to launch DSLinux from DSX own application launcher, you'll just be presented with to white screens.
- When starting DSLinux, the top-screen (console) is garbled. Just tap "Enter" to redraw the screen.
- Login with user name: root and password: uClinux.
From here, get the wireless interface up and running:
# iwconfig nds channel 2 essid gatekeeper key off
# ifconfig nds 192.168.1.42 up
# route add default gw 192.168.1.1

Oh, and the wireless is just legacy 802.11 (no 802.11b or 820.11g), so it's limited to 2Mbit/s data rate. And only WEP is supported, no 802.11i (WPA/WPA2).
Unfortunate, the DSX (file system) is not supported by DSLinux, so it's really limited what can be done. The file system is read-only so the rest of DSLinux is inaccessible. Only the most elementary programs are available like "busybox, "cat", "ls" and so on. Both "telnetd" and "dropbear" (ssh) refuses to start. I suspect that's because the read-only file system. And since no "netcat" or "socat" is present, it limits the remote accessibility further. Fortunate, support for DSX is on the TODO list.
So I'll guess I just have to wait until it's supported before I can play more with DSLinux.
