Weather software, great app for the Sheeva!

You'll eventually have to build your own kernel, no doubt.  It's pretty easy to cross-compile it on a x86 box if you follow the kernel build instructions in the wiki.  I downloaded the cross compiler from Code Sorcery (the binary tar worked fine on my Fedora-based development machine), found a mkimage somewhere, and even found a trick to modify the zImage magic number so it will boot (no arcNumber setting required, which doesn't work on my Marvell development kit).

A compile take about 5min on my relatively slow dev machine, and I've had success with 2.6.32 and a couple of other kernels.  I tftp boot the kernel, then nfs mount the (fedora or jaunty/ubuntu or whatever) file system from my dev machine.

I think it's an ideal dev environment -- except for the nfs boot problems I've been having.  Seems to boot about every third time; some hangup in udev *after* it's already mounted the root fs, but very early on.  Driving me crazy.

Let me know if you need help setting up this toolchain if you're interested.

Maybe they're finally getting caught up.

Hey Joe, I have a question about the OpenRD client -- have you started working with it yet?  I'm waiting for a plug to arrive tomorrow, and all I've been working with is a Marvell dev system.  Which is fine, I've gotten my code working, but I need to work with an installer and put it on flash as a stand-alone plug app.  The Marvell dev kit is different than the plug in how this works, has a different uboot, etc.

Is the OpenRD a lot like the SheevaPlug in terms of flash size, uboot version, etc?  For example, the dev kit's uboot won't boot via USB -- I could try and flash a newer uboot, but I'm afraid of bricking my dev kit (for no good reason).

Turns out I've got an OpenRD client board sitting here, never plugged in.  If it's closer to the shipping plug (which I'd guess it must be, since they're both made by Globalscale), then it'd be worth messing with it today to try and get the installer installed.

I've also got a pogoplug that I can log into.  I really appreciate their teeny-tiny rootfs; I'd like to do the same thing rather than the Jaunty fs if I can figure it out...

It would seem Globalscale is backordered 2-3 weeks.  Is this generally true with other suppliers?

Where are all the SheevaPlugs?  Is there that much demand?

Look into the hdparm utility.  It allows control of the hard drive's lower level functions.

You'll probably want sdparm -- hdparm is for IDE devices, sdparm is generally for SATA (most these days).

20  General Category / General Discussion / Need Sheevaplug fast -- will pay top $ for FedX! on: February 18, 2010, 10:48:08 PM
Okay, I'm putting out this plea because Globaltscale Technologies is 2-3 weeks ARO on shipping these at the moment, and I'm supposed to give a demo NEXT WEEK.  Ionics can't get me one fast enough, either.

I need one (or two, if possible) Sheeva Plugs, any version.  It has to be a real Sheeva Plug like from Globalscale, not a pogo plug (i.e., has to have usb console jack).

I'll pay up to $200/plug, plus FedX shipping to me.  Can anyone spare a (working) plug?

Please send either a private message in this forum, or to creeble at_ yahoo_ dot_ com.

Eric.
