[03:42:03] <Amanita_Virosa> evenin, anyone awake in here tonight?
[03:42:47] * Foxx sobs
[03:42:50] <Foxx> insomnia sucks
[03:42:55] <Foxx> whats up?
[03:43:17] <Amanita_Virosa> i'm trying to get my Z2 connected to my wireless network...
[03:43:33] <Amanita_Virosa> iwconfig is showing normal authenticated information, but i can't dhclient
[03:43:36] <Amanita_Virosa> not sure what i did wrong
[03:43:50] <Foxx> you using WEP?
[03:43:53] <Amanita_Virosa> yes
[03:43:57] <Amanita_Virosa> i have the keys entered
[03:44:07] <Foxx> made sure to set thr WEP key in as hex?
[03:44:22] <Foxx> not ascii
[03:44:24] <Amanita_Virosa> yea, i have it sitting next to my eeepc, which is also a linux machine and is using pretty much the same wifi config strings
[03:44:52] <Foxx> what Z2 distor are you using?
[03:44:58] <Foxx> distro*
[03:45:18] <Amanita_Virosa> debian at the moment.
[03:45:30] <Foxx> not sure then...
[03:45:31] <Amanita_Virosa> i don't much care for it, but i figured it's better to get something working before striking out on my own
[03:45:40] <Foxx> understandable
[03:45:50] <Foxx> continuet to lurk, someone will be able to help
[03:45:59] <Foxx> im pretty useless rigtt now
[03:46:03] <Amanita_Virosa> yea, normally i don't have any problem with linux... i have umpteen linux machines and actually develop embedded linux stuff for a living.
[03:46:22] <Amanita_Virosa> but this is a platform i've never touched
[03:46:38] <Foxx> its pretty much an ARM class build
[03:46:48] <Foxx> you know anything about sniffing out JTAG points?
[03:47:35] <Foxx> i have another project that I would like to find the JTAG points, I have some suspect test pads, but not sure what hard/software to use that can fingerprint them
[03:47:37] <Amanita_Virosa> haven't had a need to do so...
[03:47:38] <Amanita_Virosa> ahh
[03:47:54] <Amanita_Virosa> it's tricky, JTAG is normally inactive during system operation
[03:48:15] <Amanita_Virosa> so there's no signature you can snag on an oscilloscope
[03:48:36] <Amanita_Virosa> and it's a clocked state machine, so you pretty much end up having to drive lines to make it work
[03:48:47] <Foxx> yup
[03:48:49] <Amanita_Virosa> usually easier to just look up the ICs involved and then trace the wires
[03:49:16] <Foxx> i found some different tools, but want a seperate opinion bfore i commit to buy/build hardware
[03:49:29] <Foxx> cant trace it without removing the BGA CPU
[03:49:59] <Amanita_Virosa> for which hardware
[03:50:07] <Amanita_Virosa> i thought the Z2's JTAG was already mapped out?
[03:50:35] <Foxx> this isnt for the Z2
[03:50:49] <Amanita_Virosa> right, so which hardware are you interested in?
[03:50:51] <Foxx> http://picasaweb.google.com/FoxxOTG/TechCrapGizmos#5489740437117237522
[03:51:44] <Amanita_Virosa> oh cute
[03:51:48] <Amanita_Virosa> got a picture of the pcb?
[03:51:58] <Foxx> sure, hold on
[03:52:18] <Amanita_Virosa> is that based on shivaplug by any chance?
[03:52:20] <Foxx> http://71.246.112.254:3285/Dockstar/
[03:52:23] <Foxx> yes it is
[03:52:37] <Foxx> its a PogoPlug type device
[03:52:47] <Foxx> just not JTAG (yet) and 128MB RAM
[03:52:56] <Amanita_Virosa> now that's cool.
[03:53:12] <Foxx> no, whats cool is that they cost me $20 a pop
[03:53:29] <Amanita_Virosa> wait, really?
[03:54:09] <Amanita_Virosa> hey, what's the 10-pin header on the front connected to?
[03:54:56] <Foxx> othing, serial debug
[03:55:30] <Foxx> havent mapped the others yet, it could be JTAG, but there are also test pads on the bottom that scream "WE COULD BE JTAG"
[03:55:34] <Amanita_Virosa> you have a pinout for that?
[03:55:46] <Foxx> only in my lab notebooks
[03:56:12] <Foxx> my HDD with all my dev work on it took a shit
[03:56:19] <Amanita_Virosa> yea... except that jtag usually looks like a two-row header with a number of pins (it varies... although 10 isn't common)
[03:56:30] <Amanita_Virosa> that sucks
[03:56:33] <Foxx> i know, im familliar with jtag
[03:56:45] <Amanita_Virosa> cool. so how are you getting these things for $20?
[03:57:01] <Foxx> they were on ww.woot.com a few weeks back
[03:57:07] <Amanita_Virosa> oh. cool.
[03:57:12] <Foxx> you can find them on ebay for $30 shipped now and again
[03:57:21] <Foxx> retail price is $125+
[03:57:35] <Amanita_Virosa> they seem to retail for $80 now
[03:58:32] <Amanita_Virosa> hrm... $25 on amazon.
[03:59:39] <Amanita_Virosa> that... is pretty impressive.
[03:59:45] <Foxx> yah
[03:59:58] <Amanita_Virosa> what do the specs look like for that one?
[04:00:18] <Foxx> 1.2Ghz ARM CPU, USB host with 2.0 support, onboard serial shell, 128MB Ram
[04:00:30] <Amanita_Virosa> usb high speed?
[04:00:34] <Foxx> ogoPlugs have 256-512MB
[04:00:53] <Amanita_Virosa> sweet...
[04:01:11] <Amanita_Virosa> gigabit ethernet? really? hrm...
[04:01:32] *** azend has quit IRC
[04:01:53] <Foxx> look on the elinux wiki for specs and projects, pop into #plugapps for tech chat
[04:02:00] *** azend has joined #zipit
[04:02:16] <Amanita_Virosa> i may have to look into that one. i haven't done nearly as much as i'd like on ARM so far.
[04:02:31] <Amanita_Virosa> used plenty of other architectures... just not that one. which seems odd, when i think about it.
[04:03:53] <Amanita_Virosa> by the way... i notice the console updates... oddly on the Z2
[04:04:20] <Amanita_Virosa> especially when editing command lines in bash. is that normal?
[04:11:35] <Foxx> dpnt know
[04:27:14] <Amanita_Virosa> oh... go fig, the driver must have gotten confused. i rebooted and tried again, worked fine

[12:59:39] <bobdole369> Wow left it logged in yesterday.
[12:59:54] <bobdole369> Incidentally, noticing I'm seeing the same thing as amanita:

[14:50:00] *** gr3yw0lf has joined #zipit
[14:55:29] <gr3yw0lf> does anyone know if it's possible to run X11 on a stock zipitZ2 kernel, cross compiled with scratchbox (thanks to Ray Haque's development VM)?. I know the non-stock systems have X running, just wondered if stock firmware can do it.
[15:04:21] <Marex> gr3yw0lf: why do you want to stick with stock crap anyway ?
[15:18:51] <gr3yw0lf> Marex: well, thats one response I've been thinking about. Theres a lot of great details how to flash the system, along with uboot, and I was looking at the 2gb debian system.
[15:20:31] <Marex> gr3yw0lf: #zipit-dev
[15:21:51] <gr3yw0lf> Marex: Ahh.. sorry, guess I started in the wrong place.
[15:26:49] <gr3yw0lf> suppose I could ask whats the best kernel to move to.. Looking for X and possible tcl/tk support.

[18:59:53] <phajas> hi guys! I just got my zipit, let it update the ramdisk, and tried to flash it with aliosa27's kernel. my zipit is now, I think, bricked. any ideas?
[19:02:51] <phajas> anyone here?
[19:06:14] <Marex> phajas: #zipit-dev
[19:06:26] <phajas> thanks, I will ask there
