The first thing you need to do is fix /etc/resolv.conf to point at your name server, or you won't be able to get to the Debian package sites.
Since the board runs Debian Lenny (18.104.22.168), which is now in archive, you must also edit /etc/apt/sources.list. They took this into account and all you need to do is comment out the first line and uncomment the third line.
I got the version of the board without the real-time clock (RTC) so I needed to put something to set the clock.
First edit /etc/timezone with your timezone. Mine is, "America/New_York."
Then install ntp:
apt-get install ntp
The configuration should work as-is, but I added this near the top near driftfile:
Then I can just examine that file to make sure it works.
I figured I better update the existing packages. I have a backup of the machine if I need it.
Now the machine is looking good. I also did an apt-get install emacs, because I'm a fan and I was getting tired of vi.
I also attempted to set up things for cross-compiling from Linux (Intel) to ARM. The toolchain available here and I copied it to my Linux virtual machine and extracted it in /usr/local. Unfortunately it did not work. At all. "No such file or directory?" Odd. I will need to investigate.
Local compilation works fine, however. I wrote a hello world app (in C) and that works fine.
I'd really like to be able to run Java on this machine, because I actually like writing in Java. And then I could easily write in Eclipse on my desktop, package it in a WAR file, and deploy it onto Apache Tomcat on the TS-7500. Sadly, this is proving to be difficult. Sun doesn't make ARM JVM binaries and I'm having trouble finding pre-built alternative binaries (like OpenJDK) that work on Debian Lenny. Still investigating.
