1  General Category / General Discussion / Should i reinstall the os? on: July 26, 2009, 04:32:09 PM
some time ago i received my sheevaplug, and yesterday i plugged it, and seems to work fine... i can log via ssh...

i read some pages of the wiki:

http://plugcomputer.org/plugwiki/index.php/New_Plugger_How_To
http://plugcomputer.org/plugwiki/index.php/QuickStart
http://plugcomputer.org/plugwiki/index.php/Getting_the_Plug_Computer_Running_with_an_Operating_System
http://plugcomputer.org/plugwiki/index.php/Frequently_Asked_Questions

among others... but i'm still uncertain about what to do...


the problems of the default install doesn't seem serious....

i want to use my sheevaplug with an usb attached drive... i'll mount it on /home and on other paths (i thought of using lvm) if the space in the internal flash isn't enough for /bin /usr/bin (or whatever)

i'm sure it can be done without reinstalling, but maybe such a radical change in the mount points would be better fitted with a reinstall?

besides, (if i'll do it) i'll reinstall an ubuntu 9.04... so for my choice of distribution the default installation is just fine...

what do you suggest?

another question:
in the wiki it's written:

Currently, the Marvell LSP Linux Kernel, 2.6.22.18, at the Plug Computer site, is officially supported, however, there is an orion git tree that is regularly upstreamed to mainline kernel.

As for today (April-27 2009) kernel.org 2.6.30-rc2 already have most of the bits to get a kernel up and running, missing the cpuidle framework and a fix for the SDIO interface that can be patched from the Marvell git.

should this mean that (with uboot properly configured) any image of an arm linux distribution with a kernel 2.6.30 or more (like the upcoming ubuntu karmic) will work fine? (except for those sdio interface and cpuidle mentioned above)

thank you

You can absolutely power a 2.5" external harddrive from the plug.  In fact, if you look on the plug itself, on the electrical information sticker, you'll notice that it actually list the rated output of the usb at 750(?)ma @ 5v.  That should be enough for the external harddrive.

As anecdotal evidence.  I run my western digital passport 320G on the plug and it has been working fine so far.  Also, I used the kill-a-watt and the power draw difference between with and without the external hdd is about 3 watts.

thank you for the info... i don't have yet the sheevaplug, but now it should be on its way here Smiley

regarding hard disks....

i thought of utilizing the sheevaplug as a webserver/backup/squid cache/etc.

i have a spare wd passport 250GB:
(like this)



but i'm concerned of how much power is carried by the USB...


i don't know: all these 2,5' usb hard disks have the same energy requirements?

a thumb drive is the only option (aside from using a bigger & more power-consuming 3,5' hard disk)?


thank you for any answer

yesterday i was about to buying a sheevaplug, then i saw this note @ http://www.globalscaletechnologies.com/p-22-sheevaplug-dev-kit.aspx

Note: At the moment we just have a version for U.S. wall socket; power adaptor may be required to take this US plug to fit for other countries

from the system components table:

Power input: 100-240VAC/50-60Hz 19W
DC Consumption: 5V/3.0A

i live in europe (230V/50Hz), and from what you were saying i thought that changing the plug was enough, but now i'm not so sure Undecided

i fear that a transformer would defy the purpose of being a low-power device  Undecided
