That's because uSD is not an MTD. It's an ordinary block device, so you cannot use it with UBIFS.

Forgot to mention one important thing. If you want NAT-T in transport mode (which you do, to be able to connect to the VPN from behind NAT), you would need ipsec-tools-0.8 (0.7.3 does not support it).

Openswan as IKE daemon
Openswan and strongSwan both seem to be actively developed, contrary to Racoon which is a port of the userland tools of the KAME FreeBSD and NetBSD utilities and which development seems to have slowed to a crawl.
current state of the project
- openl2tp and openswan don't play nice together...

Openl2tp and ipsec-tools (racoon) play together very nicely. I've been using them for quite a while with built-in Windows VPN client and no problems whatsoever (although not on the plug and not with hardware acceleration). By the way, ipsec-tools-0.8 was released just a few months ago, and judging by the activity in the mailing list, they have been working hard to make it happen. (Before choosing ipsec-tools I tried a couple of *swan-s and found them to be too much of bloatware. I'm not sure it's such a good thing that they are being actively developed further).

You are right, you can't copy much of anything from /dev/null. That's where /dev/zero comes in. It produces infinite sequence of zero bytes.
You could use something like this:
Code:
dd if=/dev/zero of=/wherever/you/want/it bs=1M count=256
This will copy 256 (count=256) MB (bs=1M) of data from "/dev/zero" to "/wherever/you/want/it" and will also show you a short summary of the number of copied bytes, elapsed time and average speed.

FTP is a strange way to test hard drive performance. Why don't you keep things local? For example, copy a big chunk of data form /dev/zero.
6  Hardware and U-Boot firmware / U-Boot stuff / Re: DENX Open Das U-Boot on SheevaPlug on: August 03, 2011, 11:25:17 AM
I don't suppose anyone has any details on how to create/setup a file-system on NAND?
If I were you I would just create a UBI image on another Linux computer and then flash it to the plug with plain "nand write". You don't really need all those advanced ubifs features of u-boot.

I'm curious, why do you need a separate ubifs partition for /boot? How is that better than having the kernel on a separate raw MTD partition?

Do you mean that the CommandIR mini III is not a decent piece of hardware? http://www.commandir.com/
Sorry, somehow I missed the part of your message referring to the device type you were using. Looks quite decent to me, although I haven't used it myself.
I would expect this kind of hardware not to need those not-so-nice tricks in the driver. And since it is a USB device, I strongly doubt that the "known bug" behavior described on the LIRC page would be possible at all. You just can't have that precise timing over USB bus, so the decoding has to be done by the receiver itself.
Also considering what they say on the home page:
"Announcing the brand new CommandIR Utilities (beta), a set of command line utilities to record and send IR codes with CommandIR without LIRC."
your problem is most likely unrelated to the "known bug" of LIRC.

This is the downside of the really simple receiver circuits and can't be addressed in software except keeping the time where interrupts are disabled to a minimum.

So..... i think this will be the end?

Why the end? You could just stop trying to use those "really simple receiver circuits" that require interrupts enabled and use a "decent" receiver hardware instead...
9  Hardware and U-Boot firmware / U-Boot stuff / Re: Guruplug installer issues on: March 17, 2011, 05:55:09 AM
I apologize if I have offended you. I didn't mean to.
I know something about JTAG, a little bit about openocd, and nothing at all about GuruPlug Installer.

I have never used GuruPlug Installer, but I did use the openocd binary and GuruPlug configuration file that come with it. And everything just worked.
However, I only used openocd to flash u-boot, because the rest can be done with u-boot using serial console, which is in my experience more reliable.
That may seem too much trouble compared to a "one click" installer, but at least that way you have more control over what is happening.
So if you need help with "lower level" issues I'll do what I can, but I'm afraid I won't be able to tell you anything about how the installer works.

Looking at the log you posted earlier I would say there is a good chance that everything will work once you have the physical JTAG connection in place.
10  Hardware and U-Boot firmware / U-Boot stuff / Re: Guruplug installer issues on: March 16, 2011, 12:06:27 PM
I am using the guruplug JTAG board from globalscale, with the 4pin plug from UART to the plug 4-pin connection (could it be that openocd requires a different connection than serial console?).
Of course, openocd requires JTAG connection, which your error messages pretty clearly indicate. What makes you think that you could use serial console instead? Those are two totally different things, they have nothing in common besides the fact that they happen to have been put by GlobalScale inside the same small black box.
11  Linux Stuff / Kernel / Re: error in patchfiles for wifi client fix? on: March 10, 2011, 05:02:17 AM
Is there any reason my the Stable Wifi drive can not be included in the main kernel as opposed to a patch, so it just works?

For one thing, some of the code is released under "Marvell Proprietary" license (without further clarification what exactly that means) rather than GPL.
12  General Category / General Discussion / Re: Questions About Plug Computers on: February 20, 2011, 09:29:50 AM
low power consumption and form factor for the sake of space
nothing but a toy because it has no benefit over traditional machines other than the two things previously noted
That's exactly it.

Plug computer is a computer - no more, no less. What other benefits can you think of?

Looks nice. But I don't like the absence of internal NAND flash. Internal Micro-SD card is not quite the same.
Whats the problem with internal MicroSD in your opinion?
From my point of view its seems to be better...
- you could swap it if it get faulty
- you could reprogram it externally it the content goes bad (no need for a jtag)
- you could upgrade(?) the size
I think the main problem is reliability:
- the mechanical contacts are not as reliable as soldering
- I have read here many people complaining about faulty, slow or just incompatible SD-cards, but I can't remember anyone complaining about faulty internal flash
- internal flash should be considerably faster, as it uses much wider internal bus (although I don't have numbers at hand to compare)
- SD-card is typically used with "normal" file systems (such as ext2, ext3, ReiserFS, etc) originally meant for hard drives. While the internal FTL in the card may be doing good wear-leveling job, but I doubt it can be better than a flash-aware filesystem, such as UBIFS. Although, if the rootfs is read-only most of the time (which I believe it should be) then this won't matter that much.

What's wrong with JTAG? I like JTAG Smiley. By the way, you would need JTAG anyway to re-program U-Boot. And if you have U-Boot working then you don't really need JTAG to flash kernel or rootfs.

As for the size upgrade, IMO, if 512MB is not enough that means there is too much bloatware installed. My complete system used as network gateway/router/server/etc occupies under 100MB (of which about 40MB is occupied by Samba - a piece of bloatware I couldn't do without). I strongly doubt I will ever need to upgrade the size.

In the end of the day I have to agree that this is largely a matter of opinion.
