SheevaPlug Wishlist

Rule added -the vendor and product ID are the same, as show in the listing at the bottom, and something is different. Now when I ls /dev I get some new things listed:

Where gps1 and ttyUSB1 show up and disappear when plugging and unplugging. Also, inside 'serial' there is a file that appears and disappears and has the PL2303 in the file name. When I cat /dev/gps1 it works but no data comes through. How do you set the baud rate and parity? That could be the issue.

I don't see mygps, though. Should I?

Looks like you do have gpsd rules that are overriding my rules. Look in /lib/udev/rules.d and see if there is something related to gpsd. If there is, mv the file to somethingelse90-gpsd.rules or something.

Are you inside where you can't get a signal? I may have some time this weekend to ssh into your plug and hack around a bit if that's okay with you. Do you IRC?

Just a quick update on this thread...

I got the plug set up to compile, but I quickly ran out of space on the internal flash. I also got a Qemu ARM virtual machine built on my server, but I'm having trouble getting Qemu to use the right ethernet device so I see the outside world on the network.

I would get an SD card for the sheeva, but I think the VM is the "right" way to go. I'd like to keep the sheeva in the car when it's production ready while still being able to build packages and push to the repo.

I've also got a VPS (virtual private server) going to put all the packages on: archive.openice.org. It's got a pretty good upload connection so updates will be quick

. I'll post here when I get the repo created.

The packages that I will include in the repo for ARM:

proximity
fbd
obdgpslogger
linuxice-rules (contains udev rules for logger, fbd, etc)
gpsd (this is modified for linuxice because the ubuntu/debian package blows)

Anything else?

Stop where you are. You're wasting time with the default OS.
Ubuntu is dropping ARM support. The OS that the plug comes with is a flavor of Ubuntu. It's very limited and it doesn't support a lot of stuff. Get an SD card, and debian lenny is the easiest thing to put on it.

Update uboot to boot from SD: http://www.cyrius.com/debian/kirkwoo...t-upgrade.html
Install lenny:
http://www.cyrius.com/debian/kirkwoo...ug/unpack.html

It's stable and works very well. I've been using it since august without a hitch.

**tripzero** · 12-18-2009, 08:50 PM

What source do you have that ubuntu is dropping ARM? I find that odd since the whole reason why they did support arm is for the upcoming ARM netbooks that are about to be released.

Now that I've got the VM up and going, doing the same for debian lenny won't be a problem.

**PaulF** · 12-18-2009, 10:10 PM

I recalled from my memory incorrectly. Ubuntu is NOT dropping ARM. They are dropping support for ARMV5 and older... https://wiki.ubuntu.com/Mobile/ARMv7AndThumb
The sheeva plug is ARMV5.

That's depressing. Oh well, I guess I'll have to build a debian VM as well.

Personally I hated the version of Ubuntu that came with the plug. It was always such a mission to compile anything, the apt-get files kept on getting corrupted and needed to be deleted, the repository lacked so much software I wanted to install as well. Debian lenny was a breath of fresh air that made the sheeva plug simple again.

Nothing beats the debian as far as ports are concerned.
