Hi All,

even if I run a different plug now, I still would like to get my guru in a running state.
Anyone out there who had the same/similar issues? Or maybe a clue of what could be wrong?

Hi All,

thanks for all the great hints.
These are all very good looking machines and I'm amazed how many different products exist in this niche market.
But due to the huge hype and support that you can find for Raspberry Pi I went for that one.
I now made it to install the whole eibd/linknx/knxweb php/lighttpd stack in less than a day.
I used Raspian as the OS of choice and seems it was a good one.
Easy to load, cool setup screen which asks for all kinds of configuration options on the first run.
This really feels like a product.
If I compare this experience to the Guruplug experience, heat sink issues, JTAG hassle, strange ubuntu distro, lack of support ... to name a few.
It took me the evenings of a full week to get  the same stack running.

It will show over time if Raspeberry PI will be as robust and stable as the Guruplug was, but first impression is great.

Thanks again

The cubieboard looks pretty good.
Impressive tech specs for the low price.
Do you have any experience with community support of the board.
E.G. Linux distributions, bootloader, support (like this group), etc.
I just had little time to look into but Raspberry seems to have a huge community with lots of ready to use/modify samples.
The cubiebord though has the much better specs for a bit higher price.

Any thoughts / hints where this community meets?

I thought about the Raspberry Pi but I'm not sure how well/fast that one is.
The guru had a faster CPU but the CPU is older.
Are there experiences running something like eibd, linknx and knxweb on a raspberry Pi?

Hi All,

I have a Guruplug and would love to have a new plug for some other stuff.
I'm pretty satisfied with Guru, besides the fact that the NAND is a bit small and the heat issues with the GBit Ethernet.

I'm not sure if the heat issue is still in current GuruPlugs (I bought one of the first ones) and I'm not sure if I can take my lessons learned and apply them on another plug.

What I need is a small low power server running a webapplication (eibd, linknx, PHP)
I also would like to add some serial interface function
- I need 2 serial ports to communicate with my heat pump and air condition (I thought about a usb to serial adapter)

So any hint of what you would use and maybe why would be very helpful.

Hi All,

I just bricked my Guruplug and can consistently do so. :-)
Here the steps:
Take the latest uboot, kernel, rootfs from here http://www.plugcomputer.org/downloads/guru-plug/

Install it as stated here : http://www.newit.co.uk/forum/index.php?topic=417.0
What it says, load the 3 pieces into your nand

Start the plug.

Make sure to step down the network, at least mine needs this to not burn the house :-)
To do this I install ethtool and change my interfaces file.
I also remove the ifplugd pieces from my rc*.d directories

No I can reboot my plug and everything is fine.

If I now do

apt-get update
apt-get install build-essential

and I restart the plug, it gets stuck when it should load the console.

So I end up seeing that my network is connected with 100MBit and my time was updated from the ntpd but these messages are the last I get from the console (serial JTAG connection)

There is a message on the screen [warning] Files in /run will be invisible

In the logiles there is an additional message saying that /dev/console is not availabe.
It looks like /dev/console is just invisible for the bootprocess.

Any hint?

I'm kind of stuck as I don't know where to look next.
I would love to have my Guru running again, but somehow continuously brick it with the install of the build-essential


8  Linux Stuff / General Linux questions / Help: Missing article "Re-building the kernel and U-Boot - PlugWiki" on: May 29, 2013, 07:26:22 AM
Hi All,

I searched the web a couple of time to get a good tutorial how to rebuild both, uboot and the kernel for the guruplug.
I always find a promising link named "Re-building the kernel and U-Boot - PlugWiki" which points to http://plugcomputer.org/plugwiki/index.php/Re-building_the_kernel_and_U-Boot#Building_U-Boot but this link is dead and I can't find the article.

Is there anybody out there who has a current link to this article or maybe has the article to share?
Or maybe does someone have a even more current tutorial that I can use?

Hi Luke,

did you find an answer to this question as I look for the same.

10  Hardware and U-Boot firmware / U-Boot stuff / How to backup the nand on: October 01, 2010, 12:13:01 AM
Hi All,

I kind of finished all my config I wanted to do on the Guruplug and was now thinking about how to backup the whole nand.
I just would like to be able to copy everything over to another guru.
I do have a 4GB microSD in there so that would be my preffered target.
Any idea?
The only nand related commands I found were to write to the nand or to erase it.
I also found commands to load the kernel but nothing to dump the whole nand to a backup file.

Hope someone has an idea.
