I already tried "nosoup4u" and was unable to access the device, so I guess I changed it... Tongue
Is it possible to boot with a usb memory stick and somehow reflash the NAND?
2  General Category / General Discussion / Re: Forgotten password on: August 24, 2011, 12:14:43 PM
NAND I'd guess. Unfortunately I don't have much experience of the device (Guruplug) bought it bout a year ago, used it for a small project and forgot about it. Now I'd like to use it for another project, but can't remember the password... Sad There's nothing needed to keep on the device, so it's ok to make a clean install, if possible...

I've managed to forget the SU password, after changing it from the default one... Is there any way to reset it? or alternatively reflash the memory? and if so, how?
Thank you!
4  General Category / General Discussion / Can't run wpa_supplicant on GuruPlug on: July 07, 2010, 11:10:14 AM
I just got a Guru Plug and now trying to get it to connect to the wifi. I managed to connect to it as a access point but I'm struggling to get it to access my wifi. The first problem was that there wasn't any wlan.sh file in the /root folder (according to http://www.plugcomputer.org/plugwiki/index.php/Setting_GuruPlug_to_be_a_WiFi_Client)... instead it was located in the /usr/bin directory... I run this, hopefully not causing any damage. I manage to scan for networks using iwlist and the one I'm hoping to connect to is found. (protected with wpa, switched it from wp2 as I wasn't sure if it'd work. if wpa2 work I'd appreciate instructions how to use it instead).

The issue is that when I'm trying to execute the command wpa_supplicant -i wlan0 -c my.conf -B (after creating the conf file) I get an error message saying that wpa_supplicant isn't found.

Also, if I try to install it via apt get I get the following errors:

sudo apt-get install wpasupplicant
E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.

After I ran the wlan.sh script it disabled the access point access (which I guess it should) so I'm now connected via ethernet.

I'd greatly appreciate some help! I'm really new to Linux and my skills are limited.

Best regards

ps. I've added a quite big heatsink to prevent the GP from overheating. So far it hasn't halted or rebooted though connected to a gb ethernet with wifi on. I did it straight away just to be sure as there was so much talk about the overheating so i can't say if it'd have been an issue. The sink gets quite hot though so most likely it would have.

sorry for the spam but just one small update. These are the first lines after running "build" after them there's a lot of errors:

I manage to get the mysql_config by installing libmysqlclent15-dev and now it start
building the module, but still, it fails. I get a load of _mysql.c errors which end with

error:command 'gcc' failed with exit status 1

any suggestions? Help is greatly appreciated!

I'm trying to install the MySQLdb module but have run into problems.
So far I've installed the following packages:

apt-get install apache2
apt-get install php5-cli
apt-get install php5-mysql
apt-get install phpunit
apt-get install libapache2-mod-php5
apt-get install mysql-server-5.0

I'm now trying to get the MySQL-python-1.2.3c1 package working, and have for that
purpose also installed the setuptools, but is I try to build it I get a error saying:

EnviromentError: /usr/local/mysql/bin/mysql_config not found

I guess this path is specified in the setup_posix.py file, but I can manage to find the correct
path. I don't know where the mysql_config is actually located. Please adviced...

Thank you
- Richard

Could anyone please advice how to connect an Arduino to a plug computer?
I have Kernel version .30 installed.
Thank you! - Richard

if you downloaded the sheevaplug installer, it should be located at uboot/uboot-env/ folder

hehe didn't find it due to the "nand" in the name. Thanks!

i don't exactly know what goes wrong but just to make sure that the jtag was not disconnected at the time of your upgrade.

apparently it was because I replaced the original uImage with a .33 version.
Got it working with the original .30.  Thanks for the help!
12  Hardware and U-Boot firmware / U-Boot stuff / Re: Nandwrite issue - please advice on: May 12, 2010, 05:42:26 PM

Thank you for your reply! I managed to run the Sheeva installer but after writing the uBoot
image I get a Error saying

Error: invalide mode value encountered 0
Error: cpsr contains invalid mode value - communication failure

Any ideas what this means?

I most likely managed to destroy the root file system on my Sheeva. I'm really new to the plug and now I'm trying to resurrect the plug. I'm found the "SheevaPlug Installer" and wonder if this could help out to reinstall the system (If possible also update the kernel at the same time)?

One problem I ran into while trying to figure it out was that I can't find the "uboot-custom.txt" file. It's not located in the installer folder as mentioned in the readme, and I can't find it using finder either... Any suggestions why? Can I add it, and if so, what should be in it?'

14  Hardware and U-Boot firmware / U-Boot stuff / Re: Nandwrite issue - please advice on: May 10, 2010, 10:45:09 PM
with your cat /proc/mtd, isn't it that the one you should be ERASING is the MTD0? and not the mtd1? kernel is uImage. resolution might be to reinstall the kernel and filesystem,

Thank you for your reply! I'm really new to Linux so my knowledge is really limited... It's possible that I removed the wrong partition. The "SheevaPlug Development Kit - Writing Jaunty Filesystem on the NAND flash" just advised to remove the mtd1 "Erase the partitions on the NAND excluding the U-Boot partition (which is usually mtd0)." and this i blindly followed typing "/dev/mtd1" at the root.

If I've deleted the wrong system, could you please advise how to reinstall the kernel and filesystem? I'd greatly appreciate the help!

Thank you! - Richard
15  Hardware and U-Boot firmware / U-Boot stuff / Nandwrite issue - please advice on: May 10, 2010, 09:05:45 PM
I've tried to update my kernel but I'm having some problems. I followed the instructions in "SheevaPlug Development Kit - Writing Jaunty Filesystem on the NAND flash-Rev1.1.pdf" but...

After I erased the /dev/mtd1 and tried to nanwrite the image file, I got a error message saying "-bash: nanwrite: command not found".

Before I erased the disc I confirmed (with the find command) that both eraseall and nandwrite were available, but after the erase it stopped working. When I ls the /usr/sbin/ i get a lot of "ls: cannot access" errors and then a file listing where the nanwrite appears. When I try to run the nandwrite ./nandwrite in the folder it fails saying the files not found.

Before I erased the disk I ran the "cat /proc/mtd" command and got the following listing:

dev:    size   erasesize  name
mtd0: 00400000 00020000 "uImage"
mtd1: 1fb00000 00020000 "rootfs"

I then erased the mtd1. I haven't erased the mtd0 at any time.

Any suggestions what I should do to correct this?

Best regards
