[11:04] <phatmonkey> hey all
[11:05] <phatmonkey> just booting up my gumstix for the first time, yays
[11:05] <phatmonkey> draws less than 250ma which is nice
[11:05] <phatmonkey> i guess it will be much less without the network
[11:06] <phatmonkey> it jumps up to 500ma whenever there is network activity, ouch
[11:09] <phatmonkey> hookaay, network doesn't seem to be working... do i have to load drivers for it or something?
[11:09] <phatmonkey> time to explore the wiki...
[11:22] <phatmonkey> nothing on there about it, urgh
[11:23] <phatmonkey> methinks i'll have to hook up a serial console
[11:40] <jcoxon> hey phatmonkey
[11:42] <phatmonkey> hey
[11:43] <jcoxon> any progress?
[11:46] Action: Tiger^ decided not to use gumstix.
[11:47] <Tiger^> the docs suck, i can't get more than two serial ports, and pretty much everything is out of stock.
[11:48] <jcoxon> hmm the docs aren't great
[11:48] <jcoxon> but the mailing list is
[11:49] <jcoxon> i think its good that we don't all use gumstix though
[12:00] <phatmonkey> maybe i shouldn't have moved to gumstix ;)
[12:00] <phatmonkey> euch, these robostix headers are rather hard to solder to
[12:00] <phatmonkey> i need a smaller soldering iron...
[12:01] <phatmonkey> probably got one lying around somewhere
[12:01] <jcoxon> hehe phatmonkey don't give up now!
[12:01] <phatmonkey> the docs do suck terribly though
[12:01] <jcoxon> ask on the mailing list
[12:01] <jcoxon> or search the mailing list archives
[12:03] <phatmonkey> alrighty then, serial port hooked up
[12:03] <phatmonkey> let's see if this works
[12:05] <phatmonkey> is it normal for the gumstix stuff to get so hot?
[12:05] <jcoxon> the network bit will
[12:05] <phatmonkey> running veeery toasty
[12:05] <phatmonkey> yeah
[12:05] <phatmonkey> guess that'll stop when i turn it off
[12:05] <jcoxon> yeah thats documented
[12:05] <jcoxon> what V are you putting through it?
[12:05] <phatmonkey> 5
[12:06] <jcoxon> i think they recommend a little less
[12:06] <jcoxon> when you have network stuff
[12:06] <jcoxon> one sec let me find the page
[12:07] <jcoxon> http://www.gumstix.org/tikiwiki/tiki-view_faq.php?faqId=8
[12:07] <phatmonkey> but they recommend 5v for the robostix!
[12:07] <jcoxon> hehe
[12:07] <phatmonkey> It is best to use 4v wall adapters for configurations that do not include a robostix board.
[12:07] <phatmonkey> !
[12:07] <jcoxon> if you look at the faq they say use 4V if you don't have a robostix
[12:07] <phatmonkey> oh well
[12:08] <jcoxon> it'll be fine
[12:08] <phatmonkey> urrrgghhh
[12:08] <phatmonkey> i hate the stupid serial port names on the mac
[12:08] <phatmonkey> i have a nasty feeling to put linux on here
[12:08] <jcoxon> i use ubuntu on my ibook
[12:08] <jcoxon> just cause i use usbnet to login in
[12:08] <jcoxon> are you using a usb/serial adapter?
[12:09] <phatmonkey> yes
[12:09] <jcoxon> cu.usbserial then
[12:09] <phatmonkey> can't be arsed to boot up my linux box
[12:09] <phatmonkey> ok
[12:10] <phatmonkey> silent coolers and case are in the post, yay
[12:11] <phatmonkey> hnngrr, nothing in fink for kermit
[12:11] <jcoxon> ckermit?
[12:11] <phatmonkey> nope
[12:12] <jcoxon> http://www.columbia.edu/kermit/ck80.html
[12:12] <jcoxon> compile it
[12:13] <jcoxon> i'm just installing my 434mhz transmitter
[12:13] <phatmonkey> ah, yeah, just found that
[12:14] <jcoxon> http://www.columbia.edu/kermit/ck80binaries.html
[12:17] <jcoxon> phatmonkey, its cool that the copernicus guys asked for a link on ukhas
[12:17] <phatmonkey> howly crap, so many make options
[12:17] <phatmonkey> yeah
[12:18] <phatmonkey> one sec, i'll see if commas work in the email list
[12:18] <jcoxon> so many options?
[12:19] <phatmonkey> did you just get an email?
[12:19] <phatmonkey> your cam.ac.uk address
[12:19] <jcoxon> yup
[12:20] <phatmonkey> nice
[12:20] <phatmonkey> i checked the ukhas.org.uk stats yesterday, 0% windows, 0% IE
[12:20] <phatmonkey> haha
[12:21] <phatmonkey> i like...
[12:22] <jcoxon> where can i see the stats?
[12:28] <jcoxon> thanks
[12:29] <phatmonkey> what would the serial port be?
[12:29] <phatmonkey> tis not cu.usbserial
[12:30] <phatmonkey> not ttyUSB anything
[12:30] <jcoxon> whats your convertor?
[12:30] <phatmonkey> pl2303
[12:31] <jcoxon> do a dmesg in the terminal
[12:31] <phatmonkey> nope
[12:31] <phatmonkey> not in system.log either
[12:31] <jcoxon> i have one and it comes as cu.usbserial
[12:31] <jcoxon> plug it in and out then
[12:31] <phatmonkey> hardware growl is finding hte usb device
[12:31] <phatmonkey> maybe i need a driver for it, euch
[12:32] <phatmonkey> http://www.versiontracker.com/dyn/moreinfo/macosx/29998
[12:32] <jcoxon> i don't remember installing a driver
[12:33] <jcoxon> perhaps i did
[12:33] <phatmonkey> OS X does pee me off sometimes
[12:33] <phatmonkey> i feel... out of control when i'm doing thigns like this
[12:33] <phatmonkey> but ubuntu just wouldn't be practical for all the proprietary codecs and things
[12:34] <phatmonkey> "Click restart to finish installation"
[12:34] <jcoxon> i dual boot but mainly os x
[12:34] <phatmonkey> uuuhhh, i thought this wasn't windows
[12:34] <jcoxon> cya in a sec then :-)
[12:34] <phatmonkey> no way it's restarting on me, hah
[12:34] <phatmonkey> force quit
[12:34] <phatmonkey> let's see if this works... :D
[12:35] <phatmonkey> grrrr
[12:35] <phatmonkey> surely it should just be able to load the kernel module
[12:35] <phatmonkey> .... or whatever macs use
[12:35] <phatmonkey> crumbs, suppose i'd better restart

[12:42] Action: phatmonkey implodes
[12:42] <phatmonkey> grrrreat
[12:42] <jcoxon> weird
[12:42] <phatmonkey> *sigh*
[12:43] <phatmonkey> i think i'll just boot up my linux machine
[12:43] <jcoxon> PL-2303/X V1.1.0b1 start, Prolific
[12:43] <jcoxon> is what i get
[12:45] <jcoxon> grrr where has the tape gone
[12:47] <phatmonkey> works straight off on my linux machine, wonderful
[12:47] <jcoxon> and they complain about linux hardware support!
[12:48] <phatmonkey> yeah...
[12:48] <jcoxon> oh phatmonkey have you seen Peg III's logo?
[12:48] <phatmonkey> that's really odd you know, pl2303 convertors are *so* common
[12:48] <phatmonkey> yep, very nice!
[12:48] <phatmonkey> you going to print that out on something to put on the side?
[12:48] <jcoxon> yup
[12:48] <phatmonkey> ee hee, console doesn't work
[12:49] <phatmonkey> probably wired it up wrong
[12:49] <jcoxon> hehe
[12:49] <jcoxon> is this with a tweener?
[12:49] <phatmonkey> no, i'm being really dumb
[12:49] <phatmonkey> nope, direct to the robostix
[12:49] <phatmonkey> don't laugh... i haven't plugged the gumstix in
[12:49] <phatmonkey> *ahem*
[12:50] <jcoxon> i have to
[12:50] <jcoxon> hehe
[12:50] EvilGuru (n=evilguru@margaret2708.plus.com) joined #highaltitude.
[12:52] <phatmonkey> noop, doesn't work
[12:52] <phatmonkey> back to the soldering iron...
[12:53] <jcoxon> connect gnd first
[12:53] <jcoxon> oh is the robostix send out on 5v?
[12:53] <jcoxon> or ttl - 3.3v?
[12:55] <phatmonkey> 5v
[12:55] <phatmonkey> it is the FFUART that the serial console is on isn't it?
[12:56] <jcoxon> yup
[12:56] <jcoxon> connect gnd and tx from the gumstix first
[12:56] <jcoxon> then you should at least see it booting
[12:57] <phatmonkey> yeah
[12:57] <phatmonkey> i'll check the pinouts of the pl2303 chip again
[13:01] <phatmonkey> pin 7 is connected to
[13:01] <phatmonkey> pin 1, which is ground
[13:01] <phatmonkey> that's alright
[13:03] <phatmonkey> rxd is connected to txd and txd is connected to rxd
[13:03] <phatmonkey> erm
[13:03] <phatmonkey> maybe the usb-serial adaptor doesn't operate at 115200 baud
[13:04] <phatmonkey> eeehhh
[13:04] <phatmonkey> these are 3.3v pins
[13:04] <phatmonkey> damn, i'll need to hook it up to the 5v pins i guess
[13:05] <jcoxon> hehe
[13:05] <phatmonkey> oh wait, no, it is 5v
[13:06] <jcoxon> i can't imagine it struggling on 115200
[13:06] <jcoxon> its pretty standard!
[13:07] <jcoxon> grrr i just can't find this damn tape
[13:08] <phatmonkey> input is 5v ttl
[13:09] <phatmonkey> output is "3.3v tri-state output"
[13:09] <phatmonkey> whatever the hell that is
[13:09] <phatmonkey> but if input is working, i should at least be seeing it booting up
[13:10] <jcoxon> where does it say 3.3v tristate output?
[13:10] <jcoxon> is this the gumstix or adaptor?
[13:11] <phatmonkey> adaptor
[13:11] <phatmonkey> i don't need to touch the +5 line on the robostix do I?
[13:11] <jcoxon> doubt it
[13:11] <jcoxon> thats VCC surely
[13:12] <phatmonkey> maybe my gumstix is a dud...
[13:12] <phatmonkey> doubt it somehow
[13:12] <jcoxon> doubt it
[13:12] <jcoxon> grab an LED
[13:12] <phatmonkey> there's no other way to connect is there?
[13:13] <jcoxon> connect it to the TX and GND pins and boot the gumstix
[13:13] <phatmonkey> yeah
[13:13] <jcoxon> what cards to you have?
[13:13] <phatmonkey> netMMC and robostix without headers
[13:14] <jcoxon> on the robostix there should be 4 pins labled gumstix
[13:14] <phatmonkey> yep, that;s what i'm connecting to
[13:15] <phatmonkey> ew, these connectors for the boards are terribly flimsy
[13:15] <jcoxon> they are easily secured with spacers
[13:17] <jcoxon> hmmm i don't know why if you've connected pins 1 and 2 up you don't get a response
[13:18] <phatmonkey> might be the usb serial adaptor
[13:18] <phatmonkey> was working on the phone yesterday though..
[13:18] <jcoxon> did you do the LED trick?

[13:20] <phatmonkey> led hooked up to gnd and txd...
[13:20] <phatmonkey> nothing
[13:20] <phatmonkey> and it's the right polarity
[13:20] <phatmonkey> not good...
[13:21] EvilGuru (n=evilguru@margaret2708.plus.com) left irc: "This computer has gone to sleep"
[13:21] <jcoxon> what boards are connected right now?
[13:22] <phatmonkey> connex and robostix
[13:22] <jcoxon> hmmmho
[13:23] <jcoxon> check that they haven't labelled the pins wrong
[13:24] <phatmonkey> connecting to ground and +5 on the serial port gives me nothing
[13:24] <phatmonkey> brb, i'll get a multimeter
[13:24] <jcoxon> Q: To get serial ports to initialize the robostix board, is there a serial header on robostix that I can use? Can I connect a waysmall or tweener board instead?
[13:24] <jcoxon> A: There are two PXA serial ports exposed on the robostix headers, FFUART (on which the gumstix console emerges) and STUART but they are not level-shifted to RS232.
[13:25] <jcoxon> its 5v ttl not rs232
[13:25] <jcoxon> different things
[13:25] <phatmonkey> yep
[13:25] <jcoxon> is your adapter set up for that?
[13:25] <phatmonkey> i'm using 5v ttl headers on the usb-serial adaptor
[13:26] <jcoxon> right okay
[13:26] <phatmonkey> hmmmm
[13:26] <phatmonkey> i'm getting 2v off the +5 and gnd on the robostix serial port
[13:26] <phatmonkey> ...?!
[13:27] <jcoxon> perhaps you aren't supply enough power
[13:27] <jcoxon> or the power adapter is broken
[13:28] <phatmonkey> definately getting 5v
[13:28] <phatmonkey> i'm using my variable bench supply
[13:28] <jcoxon> put it up a little bit? ;-)
[13:30] <phatmonkey> multimeter says it's 5v, i don't want to completely kill my gumstix :P

[17:08] <jcoxon> phatmonkey,
[17:08] <jcoxon> would you like me to post you a waysmall board?
[17:08] <jcoxon> i've got a spare one
[17:08] <phatmonkey> what i really need
[17:10] <phatmonkey> is just another board with a serial port
[17:10] <phatmonkey> so i can fix this uboot issue
[17:10] <phatmonkey> silly gumstix
[17:11] <jcoxon> but with a waysmall
[17:11] <jcoxon> it has rs232 ports
[17:11] <jcoxon> so you could boot up
[17:11] <jcoxon> make hte changes then attach the robostix
[17:11] <phatmonkey> attach the waysmall doo dah to my connex?
[17:11] <jcoxon> yup
[17:11] <phatmonkey> that would be quite godly
[17:12] <jcoxon> its the original version from peg I
[17:12] <jcoxon> so it'll only provide one serial port
[17:12] <phatmonkey> argh, i probably haven't got a cable to connect to the serial port
[17:12] <phatmonkey> it's some odd connector isn't it
[17:12] <jcoxon> you don't need one
[17:12] <jcoxon> just grab some wire
[17:12] <jcoxon> and poke it in the approriate holes
[17:12] <phatmonkey> ah righty, ok
[17:12] <jcoxon> you only need 3 wires
[17:12] <phatmonkey> i'll have to find an old db9 connector then
[17:12] <jcoxon> and they are the middle row
[17:12] <phatmonkey> yeah
[17:15] <jcoxon> email me your address i'll stick it in the post tomorrow morning
[17:16] <phatmonkey> ah, thanks so much
[17:16] <phatmonkey> do you want some money for the postage?
[17:16] <jcoxon> nah its v. v. light

[17:21] <jcoxon> the light powers on so i assume it still works :-D
[17:34] <phatmonkey> :D
[17:34] <phatmonkey> such a pain though
[17:34] <phatmonkey> little rant about it on the mailing list by somebody
[17:35] <phatmonkey> he's right - this should be on the information page before buying
[17:36] <jcoxon> its true
[17:37] <jcoxon> i'm tempted to set up an unofficial doc page
[17:38] <jcoxon> start afresh with gumstix docs
[17:38] <phatmonkey> with a better, faster wiki...
[17:38] <jcoxon> perhaps not even a wiki
[17:39] <phatmonkey> i do like docuwiki, but i don't like its syntax much
[17:39] <jcoxon> i don't like wikis
[17:39] <phatmonkey> well, any unofficial documentation needs to be a wiki ;)
[17:39] <phatmonkey> letting people add stuff then checking over whatever is added is a good way of developing docs
[17:40] <jcoxon> hmmmm
[17:40] <jcoxon> but i don't want to be annoying to gumstix
[17:42] <phatmonkey> or just suggest that the gumstix wiki is started afresh
[17:42] <phatmonkey> organised well
[17:42] <phatmonkey> with a better wiki i suppose
[17:43] <phatmonkey> they should at least make a nice manual that i can refer to
[17:43] <phatmonkey> i like paper things
[17:44] <jcoxon> i'll see how the debate goes
[17:44] <jcoxon> i might get involved - suggest a new wiki + a wiki weekend of update and writing new docs
[17:44] <jcoxon> sort of like the coding weekends that openbsd have
[17:44] <phatmonkey> yeah
[17:45] <phatmonkey> it really needs to be started from scratch with good indexing
[17:45] <phatmonkey> the search on that wiki is useless
[17:45] <phatmonkey> it doesn't bring up anything relevant
[17:46] <jcoxon> i'll have a think and then suggest it
[17:47] <jcoxon> probably this evening
[17:54] <jcoxon> actually i'll do it know so i'm around to discuss what people think.
[18:00] <phatmonkey> okay
[18:09] <jcoxon> right i've sent it to the gumstix guys first
[18:10] <jcoxon> just to check its okay to suggest such a a large change
[18:10] <jcoxon> they'll be at work so they should reply pretty quickly
[18:24] <phatmonkey> i really suggest they move it to a new wiki too
[18:24] <jcoxon> i said that in the email
[18:25] <jcoxon> lets wait and see what they reply
