wens: long time not see. I've made a bpi m1+ dedicated DAC board : http://imgur.com/a/cvKIl
<luoyi>
it just sounds good. wait for the i2s driver mainline release now .
<KotCzarny>
it ate all your gpio pins?
<luoyi>
KotCzarny: I can use another type 2x20 pin jack expose all the gpio. the pic is just a prototype.
<KotCzarny>
uhum
<KotCzarny>
are needed pins spread or can be made into smaller board?
<luoyi>
and I find the a20's keyboard gpio can't be accessable easily from bpi.
<luoyi>
I want attach a matrix keyboard to it
<luoyi>
KotCzarny: it use pin 2/6/ and 35/33/31/29
<KotCzarny>
so ~6pins + 2 pins for power
<luoyi>
yes.
<wens>
luoyi: i2s is in 4.8-rc1
<luoyi>
5V and gnd. mclk/bclk/lrck/sdo
<luoyi>
wens: and the parent clock bug is fixed in the 4.7 ?
<wens>
i think so
<wens>
uhm, who said they had a a31 mele that could be used to test line out?
<luoyi>
line out ?
<wens>
luoyi: the a31 codec has headphone and lineout, 2 outputs
<wens>
well, 3, if you count the one for the phoneset
<luoyi>
so A31 integrated a dac chip in it ?
<luoyi>
I'm upgrading 4.7 now, hope the i2s and dts can still work
<wens>
luoyi: all the SoCs, excluding A80/A83T, have internal codecs
<wens>
we already support the one in sun[457]i
<luoyi>
and the internal bus is also i2s , right ?
<wens>
luoyi: no
<wens>
luoyi: internally i2s is only on a33 i think
<wens>
don't quite remember
<wens>
probably the newer socs
<wens>
the old ones are just direct dma into the codec
hansg has quit [Quit: Leaving]

ok. 4.7 is ok now. parent clock bug is fixed. but ffmpeg refuse decode some ape file now
<luoyi>
it reports: ffmpeg/ape: Incorrect extradata
<KotCzarny>
decode to .wav file?
<KotCzarny>
might be unrelated / buggy file?
<KotCzarny>
or try different app toplay audio
<wens>
sounds more like an issue with your file

anyone know how much power a BPI-M3 can supply to USB, if you use a 5v/3A input? i don't wanna cook the board, but I want to know if I can draw like 500mA for 5400rpm hard drive
<Mr__Anderson>
that's the best (and probably the only) way to reliably use a HD with the BPI-M3
MY123 has quit [Ping timeout: 258 seconds]
<buZz>
Mr__Anderson: i thought most reliable way was to use HDD over NFS
<buZz>
:D
<KotCzarny>
i just use separate wire for my hdd
<KotCzarny>
ie. one power brick, but powering sbc and hdd independently
cptG has joined #linux-sunxi
<iwh>
yeah i'm planning to use an externally powered HD
<iwh>
I presume that a 3.5" hard drive case will have its own 5v power supply and not actually try to draw the 500mA of 5v over USB
<iwh>
at least an old one I had did, not sure about the one I have now
<KotCzarny>
3.5" hdd requires 12v, i just use powerbrickthat provides twovoltages
<KotCzarny>
so 5v to the board and 5v/12v to the hdd
<KotCzarny>
one nice point of that setup is that i can connect 12v monitor too ;)
<iwh>
KotCzarny, my HD enclosure only has a 12v input unlike my old one which had a dual 5v/12v input.... so either the dc from 12 to 5 is inside the case itself or it draws from USB
<iwh>
neither the zip nor the .img matches the listed md5sum
<tkaiser>
iwh: They don't care that much about such unimportant details

stabs banana-pi.org in the face
<tkaiser>
A year ago they did not provide any checksums at all. Now most of the times correct ones. Everyone should be happy
<DaQatz>
Checksums are one of those things that should be correct, or nor provided at all.
<iwh>
it's not the first time I've had wrong checksums from them. And md5 -- come on!!!!
<DaQatz>
Not having some right completely defeats the purpose
codekipper has joined #linux-sunxi
<DaQatz>
In fact it kinda hurts things being that people will not trust the files
<tkaiser>
They did not automate this stuff, generally don't care about such stuff and then the website is done by a student in the US
<tkaiser>
So it's already great if most of the times information happens to be correct when hitting bananapi.org
<codekipper>
wens: that was me!...but the Mele I7 seems to uses the headphone pins for it's AV connector.
<iwh>
kind of like when they put a microUSB power supply input that bottlenecks the amperage that can feed the CPU and results in unnecessary throttling?
<tkaiser>
iwh: And it can also happen that they provide OS images that are 16GB uncompressed and advertised as being eMMC ready (8 GB on their boards)
<iwh>
sweet
<tkaiser>
iwh: Wrong: Micro USB leads to freezes not to throttling. When you put a heatsink on a Micro USB equipped BPi M3 you only ensure that freezes/crashes happen more often :)
<iwh>
awesome. i love that they sold packages that included microUSB + heatsink + 5v fan
<tkaiser>
iwh: And be prepared that an image that has a size of 16 GB has one partition that is 4GB in size and filled to 99% when you boot the first time
<iwh>
sweet
<tkaiser>
Apart from that the hardware is crap anyway :)
<iwh>
i have NO CLUE how they produce even moderately functioning ISO files and hardware, given their incompetence
<tkaiser>
Slowest USB-SATA bridge in the world and only 1 USB host port used to connect the two USB receptacles and the USB-to-SATA bridge
<DaQatz>
Oh god that is comically bad
<buZz>
sad timez
<iwh>
why care about that when it has a gigabit ethernet connection, tkaiser? you can overlook something as insignificant as that for a GIGABIT ethernet connection
<iwh>
i mean, if it actually functions to spec, you could use virtual interfaces and make the thing into a firewall!
<tkaiser>
iwh: Since A20 based Bananas do it better/equal, cost less, have better software/support, way better I/O bandwidth, don't overheat...
<iwh>
i'm not arguing with you. the M3 is crap.
<tkaiser>
iwh: Before I would buy one Banana Pi M3 I would buy 2 OPi Plus 2E (literally and for less ;)
<KotCzarny>
twice the fun, half the troubles
<iwh>
i bought a case with my m3 and it falls apart. I literally have to tape it together.
<KotCzarny>
iwh: wanna see my orange case?
<iwh>
just to set it down. official acrylic case.
<iwh>
KotCzarny, no.
<KotCzarny>
self made!
<iwh>
KotCzarny, i've used electrical tape cases on beagle bone blacks
<KotCzarny>
accomodates for two oranges, power brick and probably second set ofthose ;)
<KotCzarny>
its big, black, and red leds shine through the holes
<iwh>
i bought a Banana-pi.org BPI-M1+ and returned it because the 5v gpio (and sata power) didn't work. in addition, the acrylic case broke in three places as I removed the plastic film
<KotCzarny>
acrylic case is nicelooking, but utterly prone to cracking
<buZz>
KotCzarny: the cracking odds make acrylic look totally notnice to me
<buZz>
'why such a shitty case, couldnt you afford real material'
<KotCzarny>
buzz, but you can see through! shiny!
reinforce has quit [Quit: Leaving.]
<buZz>
KotCzarny: PC would be a better material if you value such properties
<buZz>
vs PMMA
<buZz>
but costs more, so they just give the equivalent of a cardboard box
<buZz>
'yay'
<iwh>
they told me to mail it back with a tracking number. I told them $55 with a tracking number or $10 without. they said without. The day after I mailed it, they told me to make sure to take a picture of the box at the post office. luckily, I had. they refunded me two months later and the $10 mailing fee another two months later.
<KotCzarny>
they could've just used some rubber suspenders to not let metal force crack thematerial
<iwh>
I can only guess what the banana pi 4.0 will be: "Lets solder two recycled CPUs to a piece of cardboard hand painted with metalic ink!"
imcsk8|zZz is now known as imcsk8
<iwh>
they'll have less return requests because people will just say "fuck it" and toss it in the garbage
<iwh>
but at least the MD5sums will match the .img files
<KotCzarny>
iwh, why bother
<KotCzarny>
those images are crap anyway
<buZz>
iwh: lol 4 months
<wens>
the opi+ 2e case is even easier to crack though
<KotCzarny>
thebest one would be made from a block of metal
<KotCzarny>
but its also most expensive/hardest to do properly
<iwh>
KotCzarny, yeah but if they KNOW that the boards are just recycled CPUs soldered to cardboard, they won't have to ATTEMPT to make the .img files bootable, so they can just use stock image files
<iwh>
and copy/paste the md5sum from the developer's sites
<wens>
KotCzarny: stamped metal would be cheaper, but probably still more expensive than plastic
<iwh>
or they can copy / paste a portion of the sha256sum and list it as the md5sum
<iwh>
i'd buy their stock

$0.25 for two random recycled CPUs, $0.25 for acid washing the CPU label, $0.00001 for laser engraving a new label on the CPU, $0.0001 for the cardboad backing, $0.25 for metalic ink, $0.10 for two USB ports, $0.05 for solder, $0.05 for website bandwidth.... profit: $69 per device sold
<iwh>
wens, stock in their company.... not their product
<wens>
i don't think you can get recycled CPUs for $0.25 :p
<iwh>
wens, you'd be surprised how cheap and plentiful recycled components are in China
<iwh>
i've spent time in china
lemonzest has joined #linux-sunxi

they pull them from the system, remove the old solder, straighten the pins, and re-laser the label

<KotCzarny>
lies. i can measure resistance on my power supply!
<willmore>
Yeah, like you can drink lava. But you can only do it once.
<willmore>
I have to agree with that article, there is no good solution for people who want an SBC with a good SATA port.
<tkaiser>
KotCzarny: The relationship between voltage and amperage regarding the most crappy way to power an SBC is like this, isn't it: The more amperage the device needs the less voltage available gets with shitty cables since ohm's law?
<KotCzarny>
if we look at the cable's/port characteristic, yes
<KotCzarny>
but bigger issue is crappy psu (which lowers voltage on higher amperage)
<KotCzarny>
which comes from bad internal design,and not just resistance
<tkaiser>
So providing a Micro USB jack is encouraging users to do it wrong twice: Combine a crappy USB cable (read as: most of them) with a crappy phone charger and you're done.
<KotCzarny>
yup
<KotCzarny>
not to mention noise/instability of those cheap phone chargers
