Maxim part provides complete USB host, speaks SPI to whatever MCU (e.g. Ben's Ingenic SOC). $4.85 Before you ask, "No, I am not competent to design this into something that plugs into Ben's 8:10 port. But thanks for asking.;)"

hello and good (european :) morning! I have at hand a nanonote which will not boot up and will not go into USB mode any more - neither by pressing U nor by shortening the USB pins on the back. could anyone here give me a hand with this, please?
<xiangfu>
cts_, Hi
<xiangfu>
good morning.
<xiangfu>
cts_, how you short the USB Pins?
<xiangfu>
cts_, what I always do is run 'watch lsusb' in one terminal. and keep trying to short the USB pins.
<xiangfu>
cts_, we will bring your nanonote back. :)

<cts_>
sorry, my nose started bleeding :(
<cts_>
xiangfu: as for the shortening; i have tried aluminum foil behind the battery and finally reverted to just using a tiny bit of solder; i tested the short to be ok.
<xiangfu>
cts_, oh~~ there is a HOT girl? :)
<cts_>
xiangfu: no, just very, very dry office air.
<xiangfu>
cts_, you mean you soldering those two pins now?
<cts_>
xiangfu: yes, I dropped just a tiny bit of solder. it's removed now, though andthe pads are clean / seperated again.
<cts_>
separated.
<xiangfu>
cts_, ok. you can try to 1. remove the battery. 2. short those two pins 3. press the reset hole at the back of nanonote.
<xiangfu>
cts_, see if the 'watch lsusb' show 4740?
<cts_>
xiangfu: no, it just shows my usb (root)-hubs and the keybord. I'v alredy tried using another port, another computer even and another cable...

<xiangfu>
cts_, if you sure those two pins are short. this maybe a hardware problem.
<cts_>
xiangfu: yes, I suppose. my hardware dealer wanted to make sure I have talked to you guys before we exchange the unit.
<xiangfu>
cts_, you can soldering those two pins , and try again. :D. just double check. no needs battery. just soldering and press reset HOLE.
<xiangfu>
1. soldering those two pins. 2. connect ben nanonote to computer 3. press the RESET HOLE.
<cts_>
xiangfu: without the battery inserted or with the battery inserted?
<xiangfu>
wothout the battery inserted.
<cts_>
opk, will do.
<cts_>
ok.
<xiangfu>
nanonote can boot with USB power.
<cts_>
there it is!! yay!!
<cts_>
xiangfu: 601a:4740 (...)
<xiangfu>
yes.
<cts_>
looks good. now I can just do a "normal" reflash, right?
<xiangfu>
that is nanonote in usb mode
<xiangfu>
cts_, yes.
<cts_>
xiangfu: it's alive again. what a good way to start a day! ;)
<xiangfu>
cts_, now you can reflash the latest version :D

cts_, thanks for buy and play nanonote. :D
<cts_>
xiangfu: you are with the manufacturer, right? who would I contact for a nannonote-based audioplayer hardware the company I work for is seeking? I was planning on presenting the device beginning of next year (we do background music for hotels and cruise ships), tha hardware seems to be a good/nice fit.

cts_, I am a software people. Sharism is hardware manufacturer , (Qi hardware is the project name)
<xiangfu>
cts_, nanonote-based audio player, what is Ben Nanonote missing compare to your 'audioplayer' ?
<xiangfu>
Sharism is the manufacturer of Ben Nanonote.
<cts_>
xiangfu: nothing. that's the beauty. I haven't tested the quality of the sound output, but adding a "real" soundcodec to the board shouldn't be that much of a problem for a company that can read the Qi designs (I can't... ;). Else it has a display, it boots fairly quickly and has a few buttons - perfect.

cts_, if it only for play music. you still needs modify the system. like direct to the music player. etc.
tonghuix [tonghuix!~tonghuix@210.76.109.165] has joined #qi-hardware
<cts_>
xiangfu: sure, but building that up from what's already there shouldn't be too much of a problem. we really don not wnt to go through the process of having someone build a custom hardware (simply because the company is not big enough and noon has any experience in this).
<wpwrak>
cts_: would you need to modify the case ?
<cts_>
wpwrak: probably not (if we stay with the built-in audio codec) - as the device just ignores if the lid is open or closed it should be fine.
<wpwrak>
kewl. we don't have design control of the case, so that would have been a bit of a problem :)
<wpwrak>
fwiw, the SoC has a "real" ac97 audio codec. not sure if the output circuit meets your needs, though
cladamw [cladamw!~adamwang@host-222.80-43-115.dynamic.totalbb.net.tw] has joined #qi-hardware
<lars_>
it is not a ac97 codec
<wpwrak>
hmm. does the data sheet lie then ?
<wpwrak>
ah, i see what you mean. only the digital side

and exactly the audio conversion "behind" the DAC seems to be a bit too much on the consumer side of things ;)

you mean the analog circuit ?
<lars_>
the internal codec is really crappy

so it's the DAC itself

so the only way to disable boot-logo is to reinstall the modified kernel, huh?
<deneme>
there is no config?
<C-Keen>
the boot logo is compiled in
<deneme>
hmm
<deneme>
kay
<C-Keen>
I don't know whether it can be switched off via a command line option
<deneme>
I am guessing not...
<C-Keen>
you can try the logo.nologo option
<C-Keen>
logo.nologo [FB] Disables display of the built-in Linux logo.
<C-Keen>
This may be used to provide more screen space for
<C-Keen>
kernel log messages and is useful when debugging
<C-Keen>
kernel boot problems.
<deneme>
either way, I still got plenty of configuration to do. I could postpone the logo config
<deneme>
but, hmm
<C-Keen>
deneme: if you just switch it off, it is a cheap shot :)
<deneme>
ehh... Ill come to that later
<mth>
which boot logo do you mean? the very first one is in the dual boot loader, the second one is in the kernel
<mth>
the one in the kernel is easy to disable, it's an option in the kernel config
<mth>
disabling the one in the boot loader would require changing the boot loader code
<mth>
why do you want to disable the logo?
<C-Keen>
ok which HW are we talking about?
<deneme>
ahem, ben
<mth>
ah sorry, wrong channel
<mth>
I assumed the Dingoo boot procedure
<deneme>
yeah :)
<C-Keen>
close enough ;)
<deneme>
fyi, why I want to disable it is because I have to 'clear' after boot to use the console
<deneme>
maybe I could run a script to do that at user-login
<deneme>
I dunno
<mth>
the boot logo should disappear at some point during the boot, doesn't it?
<deneme>
perhaps with gui
<mth>
on non-X PC installs the logo is no longer there by the time the login prompt appears
<mth>
maybe they have something in the startup scripts for that
<deneme>
I dont know tbh. In a normal pc I would edit grub
<deneme>
Ill have to play with it a bit, I guess
