85.201.147.249: /* Audio */ adding another possible output from cat /proc/asound/cards

http://www.andreabeggi.net/wp-content/53006-nslu2.jpg

==Intro==
* XScale processor from Intel (ARM) at 266MHz (133MHz before hacking...)
* 32Mb SDRAM
* 8Mb Flash
* 2 USB 2.0 ports

==Links==
* [http://en.wikipedia.org/wiki/NSLU2 Description] on wikipedia
* [http://www.nslu2-linux.org/wiki/OpenSlug/HomePage OpenSlug]

==Todo==
* Mine came with
** Server Name: LKG63472F
** Version: V2.3RA5
* Connect USB printer?
* Install backuppc -> I tried but slug is really too slow for that :-(
* Connect Tuxdroid dongle

==Debian==
* [http://www.nslu2-linux.org/wiki/Debian/HomePage Debian/NSLU2]
* [http://www.cyrius.com/debian/nslu2/ How to install Debian on NSLU2]
===Installation===
To install, follow the [http://www.cyrius.com/debian/nslu2/install.html howto], here are the big steps:
* Get [http://www.slug-firmware.net/d-dls.php Debian 4.0r0] firmware from http://www.slug-firmware.net/ and unzip it
* Power the NSLU2 and wait a bit (green light) before plugging it to the network if you've a DHCP, so the NSLU2 will choose itself IP 192.168.1.77, otherwise look to your DHCP server logs to find the IP attribution
* Go to the admin webpage, tab administration, login admin/admin
* Configure ALL network params if you don't have DHCP
* Go to the admin webpage, tab administration, login admin/admin, tab advanced, tab upgrade
* Upload di-nslu2.bin, start upgrade
* Wait for "upgrading ok" (5mins) -> wait for 3 bips (5-10mins)
* This is the last moment to plug an external USB mass-storage if you didn't do so yet
* Login via ssh installer@192.168.1.77 (or another IP got by DHCP...) pwd "install"
** I did it from an xterm but exported term mode is pure console so it's better to login from a real text console otherwise the ncurses menu is a bit broken (but still usable)
* Start installation, manually load the following modules:
** ext3-modules-2.6.18-4-ixp4xx-di
** partman-auto
** partman-ext3
** scsi-core-modules-2.6.18-4-ixp4xx-di
** usb-storage-modules-2.6.18-4-ixp4xx-di
* Whatever system you choose to partition your disk, be sure to have at least 128M of swap, I've set up 512M on my 400G drive.
* In total it took about 100 mins to complete
* If you need a console, start a second ssh connection and choose to obtain a shell
* On tasksel, I chose absolutely nothing, I prefer to take only what I need later
===After first reboot===
* dpkg --get-selections|wc -l
142
* du -hs /
179M
* dmesg:

===Tweaks===
* Ok so our NSLU2 is well underclocked, let's restore its full speed following [http://www.nslu2-linux.org/wiki/HowTo/OverClockTheSlug this howto]
Calibrating delay loop... 266.24 BogoMIPS (lpj=1331200)
Much better :-)
/dev/sda:
Timing cached reads: 90 MB in 2.00 seconds = 44.98 MB/sec
Timing buffered disk reads: 32 MB in 3.03 seconds = 10.56 MB/sec
A bit better but nothing fantastic...
* Setup static network parameters
** apt-get install resolvconf
** edit /etc/network/interfaces
allow-hotplug eth0
iface eth0 inet static
address 192.168.1.77
netmask 255.255.255.0
gateway 192.168.1.1
dns-nameservers 192.168.1.2 192.168.1.1
* From /usr/share/doc/nslu2-utils/README.Debian:
** sed -i 's/^FSCKFIX=.*$/FSCKFIX=yes/' /etc/default/rcS
** sed -i 's/^BOOTLOGD_ENABLE=.*$/BOOTLOGD_ENABLE=yes/' /etc/default/bootlogd
** Reorder the booting sequence to get ssh up earlier:
ls -l /etc/rcS.d/
S21resolvconf -> ../init.d/resolvconf
S22ifupdown -> ../init.d/ifupdown
S23networking -> ../init.d/networking
S23ssh -> ../init.d/ssh

** By default the power button restarts the slug, change the call to shutdown in /etc/inittab:
ca:12345:ctrlaltdel:/sbin/shutdown -h now

** recording at 8000 Hz mono is very poor (played on host)

===Boot diagnostics===
From /usr/share/doc/nslu2-utils/README.Debian but in case of problems I prefer to have the text here :-)
Some of the led states during boot include:
- Cycling down all the leds from top to bottom: The APEX boot loader.
- Amber status led: Initramfs is running, mounting root filesystem.
- Disk 1 on, status slowly switching between amber and green: Root
filesystem mounted, system booting.
- Disk 1 on, status green, with fast double amber flashes: System is booted
and running. The frequency of the amber flashes indicates the system's
one minute load average; faster flashes denote higher load.
- Disk 1 on, status quickly flashing between black/green and black/amber.
Single user mode. Again the flash interval denotes load.
- Disk 1 on, status slowly switching beteween amber and red: Shutdown in
progress.
