LA ?
<slapin>
Marex: hi, LA = Logic Analyser
<Marex>
slapin: hm ... you're sniffing data on the nand bus ?
<slapin>
Marex: I got myself HP 16500C chassis with 16555A logic analyser board and accessories
<slapin>
Marex: yeah
<slapin>
Marex: looking at sniffed data with tail -f is so much fun!
<rz2k>
omg
<rz2k>
where did you find it in Russia
<rz2k>
I wanted to ship myself some HP-Agilents, but shipping is total crap if weight of the package is more than 10KG
<slapin>
rz2k: it was shipped from US, then sold here for 25000RUR, then added accessories, and then it was sold to me for 33000RUR. or something.
<rz2k>
holy shit
<Marex>
how much is RUR ~ USD ratio ?
<rz2k>
30rur=1usd
* slapin
remembers when he accidentally ordered a trunk full of keyboards from Australia
<slapin>
30 rur is very rough approximation
<rz2k>
it works :p
<slapin>
actually something like 33-1 or something
<slapin>
well, if you care, I still have these keyboards and can sell them for $20...
<rz2k>
lol
<slapin>
I have about 50 of them left
<rz2k>
sell them on some hardware forum full of mechanic keyboards lovers
<slapin>
shipment cost was so big customs were very annoyed by my package
<slapin>
they seen the price $14 for the lot, and shipment of $1000+ something (but less than $2000)
<slapin>
I was going to customs office for 3 weeks to settle things
<slapin>
as the result I paid no fees, but got a lot of frustration and trouble ecplaining why I need these for personal purposes... :)

needs to configure stateful analyser, or else I will analyse data for ages
<Marex>

I've been spending last few days digging in primitive recursive functions etc.

Marex: MUHAHAHA!!!!!11 Last 2 weeks at work I was digging in 5 python scripts og 200 lines each, which had all sorts of stupid bugs from memleaks to algorithmic errors. I had to stay for a night even, for two days. And on friday I was able to talk manager into rewriting, when target is Monday, and finished it in 2 hours. Tests passed. Bingo!
<slapin>
and who will return me these 2 weeks, for which I could drink vodka and fondle tits of various sizes?
<rz2k>
lol
<rz2k>
Marex: go to your university and say everything you have on it. when I did that I got the 'half-time job' in the lab the second day. now I'm writing challenges for younger guys. we've moved from 8051 and some local clones from that era to ARM and MSP430.
<rz2k>
only if this job was payed not $150 :/
<slapin>
rz2k: local clones?!
<rz2k>
how do you like creating program for some USSR microcontroller that was designed in ~75 in 2012?
<sv>
sounds awesome
<rz2k>
lol
<slapin>
rz2k: which microcontroller? 8051 on discrete logic?
<rz2k>
No, USSR's clones of MCUs of that era. I dont clearly remember, but if you were in 90s as a computer guy, you saw that in Electronica school computers, Mikrosha and various other applications.
<Marex>
slapin: it's much worse over here
<Marex>
rz2k: I've been teaching some classes already, but it's poorly paid (I didn't do it for money) ... now I focus on my DENX job
<slapin>
rz2k: 8080 clone?
<Marex>
rz2k: DENX is awesome place to work
<rz2k>
slapin: yeah, probably. I didnt dig it too much because all documentation was clearly wrote by a guy who didnt want to teach somebody something meaningful.
<rz2k>
Sv: that sounds awesome if you know what to do and you are mature enough to understand it. If you are fresh meat from the street that wants to know how computers work, this will be the pain of searching for documentation and trying to understand wtf is going on.
<rz2k>
by mature I mean computer science mature :p

Hello.. I'm doing some hacking on my Mele A3700. I don't see much related to it on the web so far. It seems very similar to the A1000. Who maintains https://github.com/linux-sunxi/sunxi-boards and how can I contribute a mele_a3700.fex?
<Curtman>
I pulled it from my device with adb, and copied /dev/block/nanda to an image. It's the script.bin run through bin2fex. http://pastebin.com/gRfyu1fW
<libv>
Curtman: you'll have to create a dram.c for uboot
<libv>
Curtman: for this, you need this fex, but as usual some important data is missing from it
<libv>
Curtman: i trust that you already have the uart wired up?
<Curtman>
Ok. I'm very new to these devices. I mostly played with Realtek boxes like the OPlay before. Yeah I have UART. I tried USB device, but its not working. I got adb through IP:5555 and launched a shell. I wasn't able to interrupt U-Boot with my uart console for some reason.

hno: is there not enough known about the memory controller to be able to gather the unknown bits in the fex from a10 register space?
<libv>
Curtman: what ram chips are on the board, and how many?
<libv>
Curtman: hno is the main sunxi uboot man, he can quickly provide an educated guess for the missing dram parameters
slash_random has quit [Ping timeout: 246 seconds]
<libv>
Curtman: starting a wiki page on your device, and including some high resolution board pictures is always helpful too
<libv>
it is pretty straightforward, and only mildly more work than just writing plain text :)
MindBeat1 has quit [Read error: Operation timed out]
<Curtman>
I get useful data out of the uart. I see u-boot, but the press any key countdown, pressing keys doesnt interrupt it. I get no shell once its booted though. It's possible this ttl converter isn't working. Or rx on the board isn't enabled somehow.

libv, I must be doing something wrong. I go to http://linux-sunxi.org/Category:A10_HTPC click the edit tab, and how do I create a Mele A3700 category? Or where should I add it if not there?
<libv>
Curtman: i just went to the http://linux-sunxi.org/Mele_A1000 page by navigating the frontpage, then edited the url, and the wiki then offers the possibility to create a new page
<libv>
the category thing will be solved later
<mnemoc>
as they all use the same PCB it might be good to keep all models in the same page
<libv>
this is a different pcb, although similar
<libv>
Curtman: you add a [[Category:A10 HTPC]] tag into the page and it will automatically appear there
<libv>
SouL_: get uart, get script.bin, add code to uboot, then run through first steps

because working without serial is working blind and deaf

libv, Awesome, thanks.

SouL_: there is sadly no magic incantations that we can give you that will solve all your problems in a few minutes.

someone with the hw will need to go seriously poke at it

there is no way around it that will generate dependable results

I'm not
<SouL_>
Hey, I'm saying that I'm not a computer programmer and I don't know what you are saying
<SouL_>
But I can follow steps from a guide or something
<libv>
SouL_: if so, i have tracked a few on ebay before, when one is available cheaply i might grab one at one point or another, but before someone with a problem-solving mentality and the hw comes by, this device will not get support automagically
<libv>
yes, i have seen these offered secondhand in .de before

1 port.... and expresscard... I don't have such thing :)

all modern-ish laptops have expresscard o.O

the most decent i've found are 4xRJ45 switches using 5V/USB for power
<mnemoc>
Turl: maybe 14" beasts
<mnemoc>
>14"
<Turl>
>=14" for sure
<mnemoc>
laptop for me are in the 11-13" range... after that they are desktop computers with built-in UPS ;-)
<Turl>
anything <14" are unusable toys for me :<
<Turl>
I cannot comfortably fit both hands over the keyboard
<t0dbld1>
than you haven't tried the right ones
<t0dbld1>
:-)
<Turl>
and the screen is too small, I cannot do any useful work on it :<
<t0dbld1>
than resolution was to poor
<t0dbld1>
a full size keyboard is 10 7/8 " with out numbpad
<Turl>
not being able to fit more than 1 window while still maintaining readability without having to stick my face to 10cm of the screen is a deal breaker
<Turl>
no numpad itself is a deal breaker :<
<t0dbld1>
I agree that i like having numbpad
<t0dbld1>
how ever was jsut proving the error in your falicy about hands cant fit on keyboard of a smaller laptop
<Turl>
I end up hitting the table when I need to type numbers without one :P
<mnemoc>
at home you can plug a larger display and real keyboard to the laptop
<Turl>
mnemoc: what's the point then? :P
<Turl>
t0dbld1: my full kbrd with full size keys is 16" screen size
<mnemoc>
that you can suspend, unplug and take the laptop with you
<mnemoc>
16" isn't portable
<Turl>
it's 'carryable' :)
<mnemoc>
24" + 11-13" beats 16" 100x times
<Turl>
11-13 might be good on an usecase similar to a tablet, or a bit more
<Turl>
ie, carry anywhere, read email, do light work
<Turl>
16" is more of a "I need to go to X place and do Y, and I need a computer to do it"
<mnemoc>
good 11-13 with good keyboards let you program full speed without issues
<mnemoc>
note I'm not talking about "netbooks" with bending keyboards

it can be full + numpad

mnemoc: the keyboard of a 16" has the same size as a desktop one
<mnemoc>
but they have the same crappy feedback of most laptops, and irradiate heat
