First, thanks very much birdman for your reply and all of the work that you do on this forum.

Second, I got impatient (sorry) and installed Debian on a sd card thinking that might solve my problem.  Still no wlan of any variety.  Here's what I get:


Code:
[46849.871389] usb 1-1: new high speed USB device using orion-ehci and address 4
[46850.023184] usb 1-1: New USB device found, idVendor=7392, idProduct=7811
[46850.029918] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[46850.037104] usb 1-1: Product: 802.11n WLAN Adapter
[46850.041934] usb 1-1: Manufacturer: Realtek
[46850.046049] usb 1-1: SerialNumber: 00e04c000001
[46850.053289] usb 1-1: configuration #1 chosen from 1 choice

Also:

Code:
root@sheeva-dos:/home/geoff# lsusb
Bus 001 Device 004: ID 7392:7811 Edimax Technology Co., Ltd EW-7811Un 802.11n Wireless Adapter [Realtek RTL8188CUS]
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I was able to install wireless-tools and firmware-realtek, but still no wlan of any flavor.

Code:
root@sheeva-dos:/# ls /lib/firmware/rtlwifi* -l
total 124
-rw-r--r-- 1 root root 122328 Sep 18  2011 rtl8712u.bin


I've tested the usb dongle on windows (and a PC-Linux machine) and know that it works. 

Not sure what to try next?
2  General Category / General Discussion / Standard Plug Wifi Install on: July 02, 2012, 08:04:43 AM
I have successfully updated my standard plug to the latest 3.4.4 kernel.  I did then need to update my sources.list to:

Code:
deb http://old-releases.ubuntu.com/ubuntu/ jaunty main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ jaunty-updates main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ jaunty-security main restricted universe multiverse
...in order to install or update anything.

In trying to install an Edimax EW-7811Un usb wifi adapter, I get the following dmesg:

Code:
usb 1-1: new high-speed USB device number 2 using orion-ehci

So wlan0 is nowhere - don't know where to go from here?

I must say that I would be happy if I were able go get the GuruPlug run "not so hot" and easily configure it to function more like a sheevaplug.  But at this stage, when I try to search for instructions to do certain things, I find a myriad of solutions. I'm hesitant to try things for fear that I will brick my plug.  I was fairly comfortable with the sheevaplug and quite frankly when I ordered the guruplug, I expected it to be much like the sheevaplug, but with the addition of wifi and another ethernet port.  For instance, I can't even get it to install "ethtools" - I get:

 "E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?"

...but "apt-get update" (etc.)  doesn't work.

Anyway, if I could get it to do the following:

  • Boot always to "client mode"
  • Configure the wifi (client) to use a local secured ssid"
  • Be able to install "anything"!
  • Make both ethernet ports so that when you plug them in, they activate and secure an ip address and gateway
  • Make it run not quite so hot

...I would love it, keep it, and would put it to good use!

Thanks - Geoff Campbell

I am in Colorado.

I am not prepared to "wait and see" and have another power supply die.  I'm ready to move on to something else.  I would prefer to find a home for this little guy with someone on this forum - this forum has been very helpful to me with my other SheevaPlugs (although power supply problems [http://www.plugcomputer.org/plugforum/index.php?topic=5967.0] with the SheevaPlugs also).

Otherwise, I will probably go ahead and list it on eBay.

Thanks...

I have a GuruPlug Server - PLUS with the JTAG unit which I purchased in Feb. 2010.  I plugged it in when I first purchased it, but the power supply soon failed.  I recently replaced the power supply, it now boots up and serves up the info page as it should.  As I began to search for info on how to setup my application,  I started reading about all of the heat problems these units have.

Rather than modifying it to solve the heat problem so that I can use it and it won't overheat, I'm ready to "throw in the towel".

I'm located in the USA - if anyone can use it and would like to make me a reasonable offer, we can settle up quickly through PayPal and get this unit a good home!

If this violates the terms of this forum, I apologize - moderator please delete my post.

OK, I brought the two plugs back home from Mexico, ordered two power supplies from GlobalScale, waited two weeks for them to ship, installed the new power supplies, and presto - everything works!

To recap, I've bought two Sheevaplugs, one in Dec-2009 and one in Mar-2010.  Both have been in use constantly since purchase, and both power supplies obviously died. Can't imagine that my experience is that much of an anomaly.

Sure home they have fixed whatever the problem was with the original PS's.
7  General Category / General Discussion / Two plugs found dead in Mexico on: October 31, 2011, 10:41:47 AM
I'm in Mexico at a friends house - he has two original sheevaplugs which were monitoring his house (temperature and motion), which are now dead.  We get the green light (steady), no blue light, and steady ethernet lights (no blinking ever).  I've read elsewhere in this forum that this is usually a problem with the power supply.

So I pulled the power supplies and took pictures - you can see brown goop all over the place, but I have nothing to compare to.  I have no tools down here other than a multimeter - pin 1 and 4, pin 2 & 3 inputs all show 5 volts.




If I could narrow down the problem, I'm sure I could find someone here in town to do some soldering, but don't know where to start from here.  Any suggestions?

OK birdman, thanks.

I installed the headers per your instructions - when I compile, I get this:

Not sure what to try next - I see that the "build" and "source" symlinks point to an erroneous location, but have tried experimenting with several locations to no avail???
9  General Category / General Discussion / Install linux-headers on: August 16, 2010, 03:34:12 PM
Trying to compile a usb module.  It appears that I need to install linux headers for my version of linux.  uname - reports:

Linux SheevaUno 2.6.35.2 #1 PREEMPT Fri Aug 13 22:01:35 MDT 2010 armv5tel GNU/Linux

...but... sudo apt-get install linux-headers-$(uname -r)

...gives me...  E: Couldn't find package linux-headers-2.6.35.2

sudo apt-cache search linux-headers*

...reports a bunch of 2.6.28-13 thru 2.6.28.19 available packages.

Don't know anything about compiling - just trying to follow the instructions that came with the usb module package I'm trying to compile. 

For kernel updates, I've been following the instructions here: http://plugcomputer.org/plugforum/index.php?topic=1047.msg6409#msg6409   ...and I've also copied over the modules.

I see the header files at http://sheeva.with-linux.com/sheeva/

...but don't know how to install them.  I'm sure it's obvious that I'm totally lost!

man mount -> sync

So in my case, the SD card is booting the operating system (as I understand it).  So where do I stick the "sync" option?

The OS caches writes.  Always has.

I was afraid of that - thought there maybe was some way to turn this off.

Anyway, I like your suggestion - thanks!
12  General Category / General Discussion / SD Card Disk Errors on Reset on: February 27, 2010, 08:39:33 AM
I formatted a sd card per the instructions here: http://www.openplug.org/plugwiki/index.php/SD_Card_As_Root_File_System.  I am able to boot from the SD Card and I have installed a later kernel 2.6.32.4

Every time I reset (using the pin hole), I start getting disk errors like the following:

Code:
EXT2-fs error (device mmcblk0p1): ext2_lookup: deleted inode referenced: 137702
I don't recall this happening when I was booting from the nand and resetting.  I can't always do a terminal shutdown.  Seems like the SD Card is caching its "writes" or something.  Any suggestions??
13  General Category / General Discussion / Re: Boot from internal device on: February 17, 2010, 09:09:43 PM
OMG, that worked.  I'm going to bed now, but I'm hoping that still works in the morning!

Thanks again pingtoo, fragfutter, and birdman!

And, how do you know this stuff?  (Actually a rhetorical question!)
14  General Category / General Discussion / Re: Boot from internal device on: February 17, 2010, 03:12:39 PM
OK - I'm getting optimistic!  Here's what I got:

Code:
root@SheevaUno:/# modprobe ubi
FATAL: Module ubi not found.
root@SheevaUno:/# ubinfo -a
UBI version:                    1

root@SheevaUno:/# mount -t ubifs ubi0  /mnt/nand
root@SheevaUno:/# cd /mnt/nand
root@SheevaUno:/mnt/nand# ls
bin   dev  home  media  opt   root  selinux  sys  usr
boot  etc  lib   mnt    proc  sbin  srv      tmp  var

BTW - I'm not sure what kernel is on the nand device - I followed the installer instructions on the wiki, then I can't remember if I upgraded the nand kernel before creating the sd card system - not sure how to tell.

Update:  I believe that the kernel on the nand device is also 2.6.32.4 - I see that I copied over the kernel modules to /lib/modules/2.6.32.4

I totally appreciate your help - what next???

what let you believe kernel 2.6.32.4 will enable you mount mtdblock1?

The "sheeva-2.6.32.4.config" file showed the following:

Code:
CONFIG_JFFS2_FS=y
CONFIG_JFFS2_FS_DEBUG=0
CONFIG_JFFS2_FS_WRITEBUFFER=y
# CONFIG_JFFS2_FS_WBUF_VERIFY is not set
# CONFIG_JFFS2_SUMMARY is not set
# CONFIG_JFFS2_FS_XATTR is not set
# CONFIG_JFFS2_COMPRESSION_OPTIONS is not set
CONFIG_JFFS2_ZLIB=y
# CONFIG_JFFS2_LZO is not set
CONFIG_JFFS2_RTIME=y
# CONFIG_JFFS2_RUBIN is not set
CONFIG_UBIFS_FS=y

I was probably mis-interpreting that the above meant the kernel had ubifs and jffs2 support???
