<oliv3r>
have a laptop hdd usb convert plug that fits
<slapin_nb>
oliv3r: use Kicad, you then will be able to zoom using mouse wheel
<oliv3r>
slapin_nb: how can I open png in kicad!
<oliv3r>
slapin_nb: is your ddr traces properly designed?
<slapin_nb>
oliv3r: it is gittable from git://github.com/slapin/a13board, there you'll find files
<oliv3r>
slapin_nb: single sided PCB by design?
<slapin_nb>
oliv3r: rough copy-paste wise
<slapin_nb>
oliv3r: no-no
<oliv3r>
slapin_nb: from cubiboard?
<slapin_nb>
oliv3r: from OLinuXino
<slapin_nb>
oliv3r: as it is A13
<oliv3r>
ah of course
<oliv3r>
sorry
<oliv3r>
i wonder how proper you can design a board, with memory chips at oposing sides, having the shortest possible traces
<oliv3r>
slapin_nb: what are you connecting to the pads?
<oliv3r>
P1; P2; P3 etc
<oliv3r>
just breakout pads?
<slapin_nb>
oliv3r: I furst thought it will be some castleized board, but now I think I will just get thin wire in them
<slapin_nb>
oliv3r: next design will be with molex connectors or castlized properly
<oliv3r>
slapin_nb: what does castleized mean?

<slapin_nb>
oliv3r: split holes plated
<slapin_nb>
oliv3r: sort of edge connector
<slapin_nb>
oliv3r: you set the border of the board on plated holes

we're trying to hookup up uart on an a10s board and we're seeing weird characters. This indicates it's the wrong bautrate / parity / etc. Anyone knows what the default settings are?
<UltraHatomiK>
yes i come back later with my gpu problems :)
<jps>
but, yes, now i have / on sdcard, and /home on nand
<jps>
but i see nand as /dev/mtdblockXX
<UltraHatomiK>
jps: depend distro, i think
<jps>
and i dont know about repartition mtd, i am going to see link, thx again
<jps>
yep, i use ubuntu on minix x5
<UltraHatomiK>
n01 ok thk
<UltraHatomiK>
no i go for my 7" TS config on debian

jps if i can find script.bin parameter...
<UltraHatomiK>
hehe

i opened a chat to u, tell me there

Hey guys, I've been poking at HDMI audio on Android for the A10 and I'm getting some really weird sound output. It stutters and runs too fast, and I don't think it's the audio decoders in the framework to blame. Anyone know who I might talk to about that?
<hramrach>
RoadRiverRail_: sounds like wrong sound sampling frequency
<san>
We're trying to fetch script.bin from an A10s board but we're unsure how to interpret the wiki instructions
<san>
when holding the '2' key we see the '[ 0.735] Jump to fel'
<san>
but how to dump the image.. and to where is it dumped
<san>
and the 'connect to the device with USB cable' comment
<hramrach>
it's not dumped
<hramrach>
it's shown in the usb mass storage
<hramrach>
it's described quite clearly in the wiki
<san>
okay, let me be a bit more specific. We're not experienced in this at all so perhaps it's just us misinterpreting the wiki.
<hramrach>
it says to press 2 to switch the device into mass storage emulation and then copy the boot1 file form the mass storage
<san>
mass storage is the nand?
<RoadRiverRail_>
Looks like the sampling rate is 44100, which sounds right to me, but I can probably check that the sampling rate isn't getting altered somewhere.
<hramrach>
USB mass storage device is a standardized USB protocol
<UltraHatomiK>
san can is
<hramrach>
presumably the bootloader or whatever can export part of the nand over USB using this protocol
<hramrach>
RoadRiverRail_: try 22k sampling if possible
<RoadRiverRail_>
22000 ? I can give it a shot.
<san>
hramrach, does that mean it acts as an USB harddisk/dongle?
<hramrach>
yes
<san>
wow
<san>
okay didn't expect that! :)
<hramrach>
RoadRiverRail_: somebody just complaining on the ML that 44k is broken
<san>
let me get this straight.. is the (female) USB port (=host?!) now acting as a USB Mass Storage or is the TX/RX connection now serving as USB mass storage?
<hramrach>
the USB OTG port if you have one
<hramrach>
usually mini-usb
paulk-desktop has quit [Quit: Ex-Chat]
<san>
we don't have mini-usb only 'normal' usb
<san>
we're afraid for host-host connection
<hramrach>
what board do you have?
<hramrach>
does it come with a manual that describes the outputs?
<san>
it was A where the top one was RX and the bottom one TX
<hramrach>
nice
<hramrach>
maybe make new markings and put the photo on sunxi wiki?
<hramrach>
somebody might get this board and find the picture useful then
<san>
yeah I agree
<san>
no doubt we will end up doing a writeup
<san>
and I'll get 2 new devices (aka not bricked) tomorrow
<san>
so we can attempt to extract more info from those (as they still boot into android)
<san>
but the information gathering part is something we're discovering along the way. This is a hobby/side project and we're pretty new in this hardware hacking as you can tell
<san>
btw the UART shows the device as A12??
<hramrach>
it can print anything it wants
<san>
it appear that booting from SDCard hangs at 'boot0'
<san>
at least it does not print anything to UART
<hramrach>
probably the info from flash is needed for building a working bootloader
<hramrach>
or you just need a different bootloader
<san>
the sunxi-spl.bin and u-boot.bin
<RoadRiverRail_>
So, I used Audacity to downsample my test MP3 from 44kHz to 22kHz. It no longer is "running fast" in the music player, but it still stutters very, very badly.
<hramrach>
I tried vlc and it sounded kind of OK ish until it crashed
<RoadRiverRail_>
Is there a VLC for Android?
<hramrach>
I don't know
<RoadRiverRail_>
Because I'm suspecting at issue is actually something in the Android drivers for the hardware.
<RoadRiverRail_>
Ah, there is a VLC for Android, but that's beside the point, I think.
<san>
is there any listing of commands in the sunxi UART shell? In particular can I mount the /misc (nandf) partition to undo the 'echo -n boot-recovery' command
