1  General Category / General Discussion / Re: guruplug-- leds status for microdsd on: March 17, 2011, 01:17:54 PM
I think the LED labelled "D5" in the middle of the PCB blinks with SD card activity (and is lit when idle).
You won't see that LED until you remove the cover, though.
I guess you could drill a hole in the right spot..
2  Linux Stuff / Kernel / Re: hso-module? on: January 22, 2011, 11:30:38 AM
hmm.. probably it has not been ported to arm.
maybe it includes some assembler parts?
check the files hso.c, hsi.h, hsi.s, maybe hso.txt in the kernel documentation folder.
3  Linux Stuff / Kernel / Re: hso-module? on: January 22, 2011, 04:10:34 AM
Hmm.. that kernel does not come as a Debian package...

Not sure if there's a suitable kernel in debian for your plug. If so, then the dkms/modules-assistant stuff should work.

Otherwise build your own kernel: unpack the sources (in the .../source directory of the link you indicated), apply the patches (also in that directory), then copy the sheeva...config file to linux-, cd linux-, make oldconfig, make menuconfig, select your module, and then use Debian's make-kpkg to create debian kernel packages, run "make uImage" to make a uImage (that you can flash and boot). Check my page at http://oinkzwurgl.org/guruplug_kernel where I detailed how I compiled a kernel for the Guruplug (on the plug, no cross-compile).

What about "modprobe -v hso"?

But I'm guessing that you are talking about a non-standard module that is not included in your kernel.

In Debian the "module-assistant" (package) is your friend when you want to compile non-standard modules. There is extensive documentation on this (look in /usr/doc/module-assistant, the Debian wiki, the Debian manual, or google..).

Not sure what you're talking about, but wouldn't this command install it:

sudo aptitude install nodejs

6  Hardware and U-Boot firmware / Hardware / Re: external wireless antenna? on: December 15, 2010, 03:01:57 AM
I've shown the PCB to the RF guys where I work and they say that the connector is a test point (to inject test signals) and cannot (or: should not) be used to connect an antenna. We then desoldered the chip antenna and soldered a "real" antenna (from an aold WRG-54) instead. It didn't help anything. They suggested (here in my non-RF-guy words) that possibly the trace on the PCB acts as an antenna and not much of the signal actually goes into the connected (soldered) antenna. And also one would have to match the circuit to an other antenna carefully (by adding the right capacitors to the empty spaces along the antenna trace on the PCB). Unfortunately we didn't have time to investigate this any further.

I've previously also used an increased tx power setting using the config utility. That indeed improved the wireless connection for some devices (e.g. a wifi-enabled mobile phone) but didn't for others (media player with a "real" antenna). The problem with it was that the plug frequently (every other day or so) reset. That problem has gone since I reverted to the default setting. Or at least I think that the increased tx power was the problem.

I use the following command sequence:

        uaputl sys_cfg_radio_ctl 0           # radio on
        uaputl sys_cfg_channel $CH           # set channel
        uaputl sys_cfg_ssid $SSID            # set SSID
        uaputl sys_cfg_protocol 32           # WPA2
        uaputl sys_cfg_cipher 8 8            # AES CCMP / AES CCMP
        uaputl sys_cfg_wpa_passphrase $PW    # set password
        uaputl sys_cfg_bcast_ssid_ctl 1      # enable SSID broadcast
        uaputl bss_start                     # start the BSS
        # ugly hack to make it actually work..
        sleep 2
        uaputl bss_stop
        sleep 3
        uaputl bss_start
        uaputl sys_cfg_tx_power 20

8  Linux Stuff / General Linux questions / Re: uaputl sources: where? on: September 28, 2010, 01:08:28 AM
@rooster: I don't see any reference to "mssid" in the uaputl sources, the module sources or google. Anyway, I setup a uap0:1 interface that I can configure with uaputl. But the changes would apply to the original uap0 as well as the uap0:1 (and vice versa). Any idea how one is supposed to configure multiple ssids?

@sfzhi: easy:

flip@nibbler ~/PROJEKTE/guruplug $ tar -xzf uaputl.tar.gz
flip@nibbler ~/PROJEKTE/guruplug $ cd uaputl
flip@nibbler ../PROJEKTE/guruplug/uaputl $ make
cc  -Wall -c -o uaputl.o uaputl.c
uaputl.c: In function ‘apcmd_sys_config’:
uaputl.c:3817: warning: ‘argv_dummy’ may be used uninitialized in this function
cc  -Wall -c -o uapcmd.o uapcmd.c
cc -lrt -o uaputl uaputl.o uapcmd.o
flip@nibbler ../PROJEKTE/guruplug/uaputl $ ./uaputl -v
uaputl.exe - uAP utility ver 1.12

You'll need to install GCC etc. Probably "aptitude install build-essential" will do. Perhaps you need the appropriate linux-header package as well.
9  Linux Stuff / General Linux questions / Re: uaputl sources: where? on: September 27, 2010, 01:50:40 PM
Excellent, many thanks!

Both tools compile fine here (on the plug, Debian Squeeze).

Rooster, you wouldn't know if the firmware can do multiple SSIDs (virtual access points), would you?
10  General Category / General Discussion / Re: wireless setup on Ionics PlugComputer Plus on: September 03, 2010, 04:02:43 AM
You probably need to use the "uaputl" command to configure it. At least we do so on the GuruPlug. I don't know your plug, though.

11  Linux Stuff / Kernel / Re: More "traditional" /boot on *plugs? on: July 06, 2010, 12:55:41 PM
I didn't. I needed to flash the kernel, then boot it from flash. Then, once the kernel took over, it can boot the system from the SD card.
Don't worry about the flash. You can probably flash that more often than you have time to.

I'm now pretty happy with my setup. I'm not planning to upgrade the kernel anytime soon. And the plug is now my router, access point, etc. Hence, I cannot play with it anymore anyway :-)
12  Hardware and U-Boot firmware / Hardware / Re: GuruPlug Server Plus Heat Problems on: June 22, 2010, 01:46:22 AM
Btw, I'm pretty sure that you do not need two fans. Maybe you don't need one at all with additional heat sinks and if you leave enough room for convection.

I have one small 12V fan at 5V (i.e. it hardly blows out any air) and the standard heat sink gets lukewarm (maximum; at 100%CPU, USB HDD, wireless. and two 100MB ethernets).

On the other hand it doesn't hurt either.

And the internal PSU *should* be powerful enough. At least the specs allow for two USB ports at 500mA if I recall correctly.

I'd probably add a fuse.

14  Linux Stuff / Kernel / Re: More "traditional" /boot on *plugs? on: June 15, 2010, 11:01:33 AM
Actually, u-boot does know about jffs2/ubifs. It can load kernel from inside jffs2 just fine. I haven't tried ubifs though.
As far as I can tell by looking at the u-boot sources, there is some code to deal with ubifs, but I don't know what exactly it can do and how complete it is.

I've been playing with this but couldn't get it to work. This is how far I got: http://oinkzwurgl.org/guruplug_uboot
Not sure what the exact problem is. Maybe the ubifs stuff in the u-boot I used is different from what they used to initialise the NAND.
It would be nice to be able to boot from the flash partition or the SD card. One could easily update the kernel and use an initrd.
15  General Category / General Discussion / Re: Read rootfs from guruplug to tftp server on: June 09, 2010, 03:00:56 PM
I don't think so.

You could maybe dd it from /dev/mtd2 or /dev/mtdblock2..

dd if=/dev/mtd2 of=/some/where/rootfs.img
