Line 1: Line 1:
 +====== What is the TS-7553? ======
 +
 +The TS-7553 is a Single Board Computer based on a 250MHz ARM9 CPU. It is made by Technologic Systems:
 +http://​www.embeddedarm.com/​products/​board-detail.php?​product=TS-7553
 +
 +It has 64MB of RAM, 256MB of on-board flash loaded with a lean Debian distribution running busybox.
 +
 +It has three USB ports (one internal, for a WiFi dongle), a serial connector (RS-232 or RS-485) and a number of goodies, including a built-in XBee socket and a micro-SD socket.
 +
 +====== ​ Setting up the TS-7553 SBC ======
 +
 +The following steps are presented in a logical sequence so that it will minimize the number of keystrokes and play nice together. \\
 +You do not have to follow the sequence, or you may skip a step, but if you do so, don't be surprised if things don't turn out so well. \\
 +You have been warned :)
 +
 +These instructions assume that you have a micro-SD card with Linux pre-installed. You can buy the card from Technologic Systems but you don't have to, they kindly make the distribution available on their web site so that you can burn it yourself on a card you bought elsewhere.
 +
 +For the latest micro-SD card image for the TS-7553, check this link: \\
 +ftp://​ftp.embeddedarm.com/​ts-arm-sbc/​ts-7553-linux/​binaries/​ts-images/​2gbsd-noeclipse-latest.dd.bz2 \\
 +and copy instructions (for Linux) are there: \\
 +http://​wiki.embeddedarm.com/​wiki/​Ts75xx_sd_image
 +
 +(as of November 18, 2012, the most recent archive is dated September 2011)
 +
 +The instructions on the Technologic web site assume that you have a Linux machine (or a Linux distro running in a VirtualBox under Windows) to format and copy the image to the SD card so that it can boot under Linux. \\
 +If you do not have a Linux box handy, Image Writer for Windows, ​ https://​launchpad.net/​win32-image-writer/​+download is a tool that can write an image file containing a Linux partition to an SD card, and conversely can save a Linux formatted SD card as an image file.
 +
 +
 +====== Boot from SD card ======
 +
 +  - boot from SD card: type exit when first booting from busybox. This boots a second version of busybox from the SD card. Alternately,​ remove the SD Card jumper behind the power connector to always boot directly to the SD card.
 +  - by default (as configured when I bought the SD card from Technologic Systems), when booting from the SD card, you get another instance of busybox. To boot the full Debian distro from the micro SD card, once booted into the SD card busybox, change the linuxrc symlink to boot from the Debian install on the SD card. The "​save"​ command saves the change to flash, so you only have to enter this command once.
 +
 +<​code>​
 +# cd /
 +# rm linuxrc
 +# ln -s linuxrc-sdroot linuxrc
 +# save
 +WARNING: do NOT power-down while saving/​copying!
 +Saving [initrd] to NAND ... done
 +
 +</​code>​
 +Note the message from the console indicating the flash has been updated. ​
 +
 +When you get the "​done",​ type "​exit"​ to boot from SD card.
 +
 +====== Enable DHCP Client ======
 +
 +If necessary, enable dhcp client by adding dhcp to the file "​interfaces"​ in /​etc/​network and commenting out
 +the static IP setting. \\
 +Alternately,​ you can set a fixed IP address as needed. \\
 +You will need to use the vi editor at this point since that is all that is available until you have internet access and can install other software. \\
 +Good luck... \\
 +For the vi challenged among us (that means pretty much everybody), check this page: http://​www.lagmonster.org/​docs/​vi.html
 +
 +<​code>​
 +# Used by ifup(8) and ifdown(8). See the interfaces(5) manpage or
 +# /​usr/​share/​doc/​ifupdown/​examples for more information.
 +
 +auto lo
 +iface lo inet loopback
 +
 +auto eth0
 +iface eth0 inet dhcp
 +#iface eth0 inet static

 +        #gateway 192.168.0.1
 +
 +#auto eth1
 +#iface eth1 inet dhcp
 +</​code>​
 +
 +
 +====== Update distribution and fix GPG key problem ======
 +
 +When updating the Debian based system with apt-get update, it may happens that the apt-get displays an error message like:
 +
 +<​code>​
 +W: GPG error: ftp://​ftp.debian.org/​ testing Release:
 +The following signatures couldn'​t be verified because the public key is not available: NO_PUBKEY 010908312D230C5F ​   ​
 +
 +W: There is no public key available for the following key IDs:    ​
 +010908312D230C5F
 +</​code>​
 +
 +This is a new feature of the apt-get system that guarantee the authenticity of servers for updating Debian.
 +
 +Solution: Simply type the following commands, taking care to replace the number of the key that displayed in the error message:
 +<​code>​
 +gpg --keyserver pgpkeys.mit.edu --recv-key ​ 010908312D230C5F ​   ​
 +gpg -a --export 010908312D230C5F | sudo apt-key add -
 +</​code>​
 +
 +====== Install much needed software ======
 +
 +Once your TS-7553 is connected to the internet, you can install many pieces of software. \\
 +The first thing you need is a decent text editor. I recommend Joe's editor.
 +
 +<​code>​
 +# apt-get install joe
 +</​code>​
 +
 +This will take a minute or two. \\
 +Joe's editor is based on the old Wordstar commands. To display the help from within Joe's editor, simply press Ctrl-K then H.
 +
 +You can similarly install the php5 module for the Apache web server.
 +
 +Some packages have dependencies,​ so that you may have to install other packages before installing the package you want, but the apt-get installer will tell you.
 +
 +To find which packages are already installed, use dpkg --get-selections
 +
 +Here is an example of what I have on my TS-7553 at the moment:
 +
 +<​code>​
 +ts7500:~# dpkg --get-selections
 +adduser install
 +alsa-base install
 +alsa-utils install

 +As you can see, this flash drive is actually formatted as 4 partitions, so mounting it will be a little different than it would be for a drive with a single partition since you do not know beforehand which partition has the data you are interested in. \\

 +The biggest partition is 1,310,592 blocks and formatted FAT32, that's the one we want here.

 +====== Enable the WiFi-G Wireless USB Dongle ======
 +
 +You may not need the WiFi interface, but if you do, here is how to set it up.

 +Here is an example script to mount and start the WiFi dongle:
 +
 +<​code>​
 +#!/bin/bash
 +
 +PATH="/​usr/​local/​sbin:/​usr/​local/​bin:/​sbin:/​bin:/​usr/​sbin:/​usr/​bin"​
 +
 +USB=`iwconfig 2>&1 | grep rausb | cut -b 1-6`
 +echo $USB
 +ifconfig $USB up
 +iwconfig $USB essid "​XXXXXX"​ key "​xxxxxxxxx"​
 +#ifconfig $USB 10.0.3.100
 +dhclient $USB
 +</​code>​
 +
 +The symbols enclosing the iwconfig command are backticks, not regular quote marks.
 +
 +The script finds the name of the USB WiFi adapter, saves it to the variable USB and uses that variable for the following commands. Note this setup works for WEP, not for WPA or WPA2.
 +
 +Replace XXXXXX and xxxxxxxx as appropriate for your network settings. \\
 +I named this script "​mountwifi"​ and I put it in my home directory.
 +
 +Done!
 +
 +Note: you may notice that the eth0 interface is always enabled by default. This may confuse the board in some situations. ​
 +If you are having difficulties pinging your access point from the TS-7553, try to disconnect eth0 by using the following command:
 +
 +<​code>​
 +ts7500:/# ifconfig eth0 down. 
 +</​code>​
 +
 +====== Enable the DHCP Server ======
 +
 +This will be required if your TS-7553 is used as a gateway or server.
 +
 +You need to install the dhcpd daemon package.
 +<​code>​
 +root# apt-get install isc-dhcp-server
 +</​code>​
 +
 +Answer the questions and the installation will complete.
 +
 +====== Mount the root filesystem with -noatime option to speed up and reduce Flash wear ======
 +
 +//From Technologic Systems customer support: //
 +
 +The root filesystem is mounted from the initrd.  ​
 +
 +On the sd card this is /dev/nbd8, or /dev/nbd2 for the XNAND.  ​
 +
 +In the linuxrc script you can look for the calls to mount /mnt/root/ which can be modified to include ​
 +"-o noatime"​.
 +
 +====== Eye Candy: set ls to use colors by default ======
 +
 +Open ~/.bashrc with a text editor and add: alias ls="ls --color=always"​
 +<​code>​
 +#joe ~/.bashrc
 +</​code>​
 +add
 +<​code>​
 +alias ls="ls --color=always"​
 +</​code>​
 +
 +====== Example Configuration ======
 +
 +Here is what I get when booting from SD card:

 +====== TIPs ======
 +
 +==== How to tell which partition you booted from ====
 +
 +The directory structure looks alike with all the boot devices, so it is not readily easy to tell if you booted from NAND Flash or from the SD card.
 +
 +Simply look at the /​proc/​mounts file:
 +
 +<​code>​
 +ts7500:~# cat /​proc/​mounts
 +rootfs / rootfs rw 0 0
 +/dev/root /initrd ext2 rw 0 0
 +proc /proc proc rw 0 0
 +sysfs /sys sysfs rw 0 0
 +tmpfs /​initrd/​mnt/​root/​lib/​modules tmpfs rw 0 0
 +/dev/nbd3 / ext3 rw,​data=ordered 0 0
 +tmpfs /​lib/​init/​rw tmpfs rw,nosuid 0 0
 +tmpfs /dev tmpfs rw 0 0
 +tmpfs /dev/shm tmpfs rw,​nosuid,​nodev 0 0
 +devpts /dev/pts devpts rw,​nosuid,​noexec 0 0
 +ts7500:~#
 +</​code>​
 +
 +From the /dev/ndb3 line, we can tell the root partition is on the NAND flash (the built-in flash on the TS-7553)
 +
 +In another case:
 +
 +<​code>​
 +ts7500:~# cat /​proc/​mounts
 +rootfs / rootfs rw 0 0
 +/dev/root /initrd ext2 rw 0 0
 +proc /proc proc rw 0 0
 +sysfs /sys sysfs rw 0 0
 +tmpfs /​initrd/​mnt/​root/​lib/​modules tmpfs rw 0 0
 +/dev/nbd3 /​initrd/​mnt/​root ext3 ro,​data=ordered 0 0
 +/dev/nbd9 / ext3 rw,​data=ordered 0 0
 +tmpfs /​lib/​init/​rw tmpfs rw,nosuid 0 0
 +tmpfs /dev tmpfs rw 0 0
 +tmpfs /dev/shm tmpfs rw,​nosuid,​nodev 0 0
 +devpts /dev/pts devpts rw,​nosuid,​noexec 0 0
 +ts7500:~#
 +</​code>​
 +
 +Here we booted from sd card /dev/nbd9
 +
