[14:45] <riksta> hey anyone alive that can help me with the gumstix? I'm just looking at the wiki, but I can't find how to transfer the rootfs image using usbnet

[15:00] <riksta> jcoxon: ping
[15:01] <jcoxon> hey riksta
[15:02] <riksta> hey dude, i was wondering if you can spare me 5 minutes?
[15:02] <jcoxon> of course
[15:02] <jcoxon> whats the problem
[15:02] <jcoxon> ?
[15:02] <riksta> I got a usb cable for my waysmall gumstix, and I'm got the usbnet stuff working, and i can ssh into the gumstix (i know you said i cant upgrade the firmware over BT)
[15:02] <riksta> so now im having a hard time figuring out how i get into the place to flash the firmware over usb
[15:02] <jcoxon> you can't upgrade over usb as well
[15:02] <jcoxon> only serial
[15:02] <riksta> bollocks
[15:03] <riksta> ok, can i get the cable at maplins?
[15:03] <riksta> is it just a ps/2 -> serial?
[15:03] <jcoxon> nah thats a serial port on the waysmall
[15:03] <jcoxon> its a weird format though
[15:04] <riksta> oh yeah..i just inspected it
[15:04] <jcoxon> there is a pinout on the wiki
[15:04] <riksta> damn where am i going to find one of them!
[15:04] <jcoxon> so its just matter of using wire
[15:04] <riksta> im not very electonically competatnt
[15:04] <jcoxon> i got a old serial cable
[15:04] <jcoxon> lobbed off one end
[15:04] <riksta> competant
[15:04] <riksta> is it safe to just stick the wires in?
[15:04] <jcoxon> then used a led and battery to work out what wires were what
[15:05] <jcoxon> i've done it a couple of times
[15:05] <jcoxon> never had a problem
[15:05] <riksta> oh god....im useless at that stuff
[15:05] <riksta> how does an LED come into it
[15:06] <jcoxon> well first find a pinout of a standard serial port
[15:07] <jcoxon> then you can work out which wires (on the cut off end) lead to the particular pins
[15:07] <jcoxon> but making a circuit
[15:07] <jcoxon> if the led turns on then that wire leads from that pin
[15:08] <riksta> i think i might just buy a MMC card....its less technical
[15:08] icez (n=icez@ip68-3-56-121.ph.ph.cox.net) left irc: Remote closed the connection
[15:09] <riksta> or do i still need to be using the serial?
[15:09] <jcoxon> you'll still need serial
[15:09] <jcoxon> to access uboot
[15:09] <riksta> joy
[15:10] <jcoxon> it really isn't difficult
[15:10] <jcoxon> you only need to set up 3 wires
[15:10] <jcoxon> ground, tx and rx
[15:10] <riksta> yeah, it just scares me doing that stuff :P
[15:13] <riksta> so i take a serial cable, chop the end off...then how do i find out which wires i want?
[15:14] <jcoxon> well you can see which of the wires lead to the particular holes on the remaining connector
[15:14] <jcoxon> i use an led and battery to make a circuit and test each wire in turn
[15:15] <riksta> but i dont get where you insert the led
[15:15] <riksta> sorry to be dumb, wires n things scare me
[15:15] <jcoxon> hehe
[15:15] <jcoxon> nah its fine
[15:16] <jcoxon> well if you push one end of the led into one of the holes on the serial connector on the end of the connector
[15:16] <jcoxon> and then connect the other pin to a battery
[15:16] <jcoxon> one of the wires from the serial cable will complete the circuit and turn the led on
[15:19] <riksta> good point
[15:21] <riksta> how do i know which pins are rx,tx and ground on the std com1 style connector
[15:21] <jcoxon> you need a pinout
[15:22] <jcoxon> search on google for DB9 pinout
[15:22] <jcoxon> the search phrase rs232 would help as well
[15:23] <riksta> http://www.lammertbies.nl/picture/db9_pin_name.png so i'd need 2,3 and 5?
[15:23] <jcoxon> yup
[15:24] <riksta> ok well the cable i found has that connector on one end and then a DB25 male (the pins in the connector) on the other end
[15:25] <jcoxon> that should do
[15:25] <riksta> so iguess in the DB25 judging by this page a lot of those pins are unused
[15:25] <jcoxon> yup
[15:32] <riksta> sweet, found a multimeter
[15:32] <riksta> im mapping the wires as we speak
[15:33] <jcoxon> excellent
[15:40] <riksta> hahah nice
[15:40] <riksta> ok mapped them all
[15:43] <jcoxon> now you need to get the pinout for the serial ports on the waysmall
[15:43] <jcoxon> they are on the wiki
[15:43] <riksta> yep
[15:43] <riksta> whats the kernel module i need to load on my client machine for serial
[15:44] <riksta> is it standard
[15:46] <jcoxon> should be standard
[15:48] <jcoxon> brb
