Getting started with a new SheevaPlug

by John Winters :: Rate this Message:

Reply to Author | View Threaded | Show Only this Message

I've just received a SheevaPlug freshly delivered and obviously I didn't
read any of the instructions before powering it up.

I'm slightly puzzled.  I connect the USB lead to another box, fire up a
connection over ttyUSB0 and am immediately presented with a login which
says:

Ubuntu jaunty (development branch) debian ttyS0

debian login:


I wasn't expecting to find Ubuntu pre-installed.  I've had a little hunt
to see if I can find the login information, but without luck so far.

Is it normal for these to come with a booting Ubuntu system pre-installed?

TIA,
John

The manuals say that they provide either an Ubuntu or a Gentoo. I
still have to see where to get that gentoo from.

Welcome to the SheevaPlug world!

John,

Yes, quite a few of us were surprised to see it grab a dhcp address and come right up. If you want an alternative to debian/ubuntu, the is armedslack, Slackware distribution for ARM and Sheevaplugs as an arm package. Very slick so far... armedslack.org

Looks like you got a reply with the root pass.

http://plugcomputer.org/ is one of the best resources I've found with my
week-old sheevaplug

First thing I would suggest is to update the u-boot environment - the
latest version supports booting from SD card.  So far I have updated
u-boot, pushed their alpha6 Ubuntu image to NAND, then set up
dual-booting Lenny from SD and NAND.  Next thing I'd like to try is sort
out how the alpha6 installer works and get a Debian install to NAND
working right.

Kind regards,
Michael

My apologies gents, forgot this was the debian-arm mailing list - thought it was the sheevaplug one.

Very not cool to point to the slack-arm distro. mea culpa.

Yes, that's quite normal. (Although finding it on /dev/ttyUSB0 isn't ---
USB0 is usually the JTAG port and USB1 is the serial console.)

The Ubuntu installation's actually in pretty poor shape and apt won't
work out of the box. (You can't use apt on a jffs2 filesystem since it
doesn't support writeable mmap.) Recommendations are to install Martin
Michlmayr's u-boot upgrade (which allows booting off SD card) and then
to put Debian on it...

I have a writeup here, although it's now a bit old and out of date:

I've connected my SheevaPlug to 3 different Linux systems and on all of
them it produces only a /dev/ttyUSB0, which is the console.

Done that.

And that, but then I did an "apt-get dist-upgrade" and that seems to
have broken booting again.  Waiting in hope for clues about why.

Cheers,
John

I've done a bit of research and explained this.  Recent Linux kernels
apparently recognise JTAG ports explicitly and don't assign them a
serial port.  Instead you access them with openocd.

Now I just need to find out why the kernel doesn't boot.

It's entirely possible they've fixed it. My system came with
/var/cache/apt on a ramdisk to get around this, except they hadn't put
in the script to populate it on startup (creating the 'archives'
directory, etc), which meant that apt would get confused and fail.
Possibly they've switched to yaffs; jffs2 works very badly on big disks
and yaffs is a much better choice.

I don't use the flash for anything, instead running Debian off USB, so I
wasn't terribly interesting in delving deeply into then workings of the
Ubuntu system on it.

Just FYI

I followed Martin's awesome page on installing debian and my plug has  
been up awhile now

local@plug:~$ uptime
  21:13:54 up 44 days,  3:46,  1 user,  load average: 0.05, 0.04, 0.00

local@plug:~$ uname -a

local@plug:~$ cat /proc/cpuinfo

I have a 30GB USB SSD attached to it as the root device and I'm using  
it as an rsync repository for a server I have out on the net.

It's been rock rock solid and seems quite fast as well.
