Alright ! I finally got to UART to talk to me on my MK802... Ended up using the UART on a RaspberryPi... Now I have a better idea of what is going on.
<specing>
RPI: the $15 serial dongle
<coolhp>
Failed to execute /init. Attempting defaults... I think my rootfs has some issue.
<coolhp>
RPI is awesome :-)
<rm>
specing, you mean 35
<rm>
coolhp, that message is no problem
<rm>
I have it too and the kernel boots
<rm>
probably those "defaults" do indeed work after being tried
<coolhp>
Actually, it doesnt do much... I think the boot params are wrong... it should be /sbin/init instead of /init
<coolhp>
And that's why my wireless wouldnt come up... since it doesnt run init, it doesnt load the additional modules.
<coolhp>
ohhh... Hackberry is available now ! :-D
<RaYmAn>
it was yesterday too? Just only 512mb version (still the case, isn't it?)
<rm>
I think all three of my devices boot fine while still printing that /init message
<Mazon>
I'd take the board if it had 1GB ram and sata
<rm>
non-obvious what's the use for 1 GB of RAM w/o SATA or even a case
<Mazon>
streaming media player ?
<rm>
what kind of media can't play on 512 MB of RAM?
<rm>
afaik RAM is not issue at all
<rm>
even Raspberry Pi with ~224 runs XBMC
<Mazon>
yeah, albeit shitty
<rm>
uncased is actually a huge downside when you think of it
<rm>
and if you were going to use it for anything other than a "debug board"
<RaYmAn>
There are plenty of cases where a development board without sata or gpio though
<Mazon>
*shrug* my rpi doesn't mind being uncased :)
<rm>
and needing to do a custom case is easily +$15-30
<Mazon>
afaik the xbmc people said that less than 512 MB ram for xbmc on android = bad
<rm>
I am from those old fashioned people
<Mazon>
512 might then be enough - but some skins might push that
<rm>
who mean XBMC on GNU/Linux
<rm>
when they say XBMC
<rm>
afk :)
<RaYmAn>
just seems a bit naive to say that a 65$ dev-board with 1gb ram is "uninteresting" in general. There are plenty of valid uses for such a board. But yeah - shipping seems a bit excessive
<Mazon>
I am just waiting for whoever makes a 1GB mele like unit :)
<mnemoc>
RaYmAn: they burned your A13-olinuxino :'(
<rm>
RaYmAn, okay, let's put it another way
<rm>
it's overpriced. :)
<RaYmAn>
mnemoc: yeah :(
<RaYmAn>
mnemoc: At least I'm still getting one! :)
<RaYmAn>
mnemoc: I'll be at a festival thingy for at least next week so that helps me ;)
<mnemoc>
:-)
<RaYmAn>
it fits well - i'll be back around the 12th, then be hungover for a week or so and then it'll get sent ;)
<mnemoc>
hehehe
<Mazon>
really impressive work from the olimex people
<coolhp>
How many microsoft engineers does it take to change a lightbulb ?
<coolhp>
None.. when a lightbulb burns at MS, they declare obscurity as the new standard.
<mnemoc>
Mazon: yes, amazing
<mnemoc>
Mazon: and (thanks to you?) he finally accepted to make the A10-olinuxino with 1GB so more awesomeness is comming :)
<mnemoc>
coming*
<RaYmAn>
ooh
<RaYmAn>
now that's interesting :>
<RaYmAn>
Not that I have any usecases in mind for any devboards at all, except dev'ing! :>
<mnemoc>
hehe
<mnemoc>
I'm advocating for APC.io's formfactor.... but I think I'll fail
<mnemoc>
either way, I want that board :p
<coolhp>
Does umount imply sync ?
rellla has quit [Ping timeout: 248 seconds]
<mnemoc>
umount will block until it's sync'ed
<RaYmAn>
mnemoc: hmm, it's standardized io header? e.g. so it fits in standard cases with a output shield?
<coolhp>
which eventually happens or does it have to be called ?
<mnemoc>
RaYmAn: yes, and use P4's connector for power
<mnemoc>
RaYmAn: powering the SATA disk with the same "normal" PSU
<mnemoc>
RaYmAn: extension headers would be on the inside obviusly
<mnemoc>
i believe it's a good way to avoid unhealthy competition between tom's 6layer cubieboard and Tsvetan's A10-based board
<mnemoc>
obviusly one olideskino with quad imx6 will be even more awesome :)
<mnemoc>
coolhp: eventually will happen
<mnemoc>
coolhp: but manual calls to `sync` will help
<coolhp>
Just a fun little fact : I'm debugging my MK802's boot issue and using a small probe to read the UART TX pin. In between 2 boots, I start seeing stuff appear on the serial terminal even though the probe isnt touching TX.... As it turns out, the probe was a little too close to the Wifi antenna on the MK802 and I'm picking up garbage :-)

<coolhp>
I'm trying to turn CPU_FREQ to off on my MK802 kernel : Do I have to do a make clean after making a change in .config or will a make uImage take the change into account ?
<specing>
I have an AVR SMPS setup here that can theoretically handle up to 100W :P
<mnemoc>
:o
<specing>
100khz PWM wired to a 9A 60V mosfet
<specing>
though the input must for now be below 5.5V as I haven't made the driver circuitry necessary? for higher voltages yet
<rm>
coolhp, make clean not needed
<rm>
also turning off cpufreq not needed too :)
<mnemoc>
coolhp: disabling no_hz and preempt fix weirdness problems
<coolhp>
Tried turning them off => no go :-(
<coolhp>
But I didnt do a make clean between my make uImage
<coolhp>
should I ?
<rm>
what problem do you have atm?

steev: hi, how many sata drives the imx6 support? just one?
<steev>
yes, only 1
<specing>
Isnt the imx6 shipped with the vivante GPU?
<mnemoc>
wet dreams about a neo-itx imx6 NAS in a sexy mini-itx case are over
<specing>
Indeed
<specing>
But NAS usually implies more disks
<specing>
Does it have a PCI controller?
<specing>
One could use a PCI RAID with it
<mnemoc>
WarheadsSE has a 6x2.5 in 1 5.25 bay
<thefrog>
I have a few old SCSI raid enclosures... in storage
<blahee>
WarheadsSE: i am familiar for distcc. Used to maintain centos/s390(x) under hercules emlator and distcc was major part of it to be abke to compile anythign fast enought - not just distrcc, but cross-compilers under x64 too
<WarheadsSE>
some of these single-sata boards also support multipliers
<specing>
steev: Does the imx6 sata support multipliers?
<steev>
possibly if you had a way to power them all
<WarheadsSE>
externally supplied like the above should work
Almamuerta has joined #arm-netbook
<WarheadsSE>
You'd just have to have an appropriate enclosure with the built-in multiplier
<mnemoc>
that little case has a 200W PSU
<WarheadsSE>
ALARM is awaiting some imx6 devices
<WarheadsSE>
Might end up as part of the farm
<steev>
the mx6 DOES support multipliers, however they can't be chained
<mnemoc>
\o/
<steev>
so if you get a board that's already using a multiplier you're screwed
<WarheadsSE>
Well, yeah
<mnemoc>
Tsvetan is going to make imx6 boards... we only need to convince him to go PCish (neo-itx, ATX style power and all connectors on the i/o shield :p
<specing>
Those multipliers are almost as expensive as SCSI controllers
<WarheadsSE>
sometimes
<WarheadsSE>
I have a 2 disk sata dock from thermal take that has a multiplier in it
<WarheadsSE>
Can't sata boot an oxnas with it because of that.

mnemoc: atx style power is overkill
<mnemoc>
steev: yes, but that's what's already on the case...
<mnemoc>
steev: and you need 12V/5V to power the sata drives anyway
<mnemoc>
btw, I'm talking about the 4pin connector, not the large one
<specing>
I have a solution to that 12V/5V problem
<specing>
Well atleast a concept anyway
<specing>
MCU-powered SMSPs!
<mnemoc>
o.o
<specing>
you could take an off-the-shelf laptop (19V 4A) power supply and convert that to all the voltages you need + have a battery for backup
<thefrog>
specing: neat idea
<specing>
My SMPS code/hardware is not ready for use yet as I still get 75V spikes
<specing>
And Im playing with a HD44780-style display at the moment so it isn't going to get usable in a short time
<specing>
I was thinking about a 55Ah 12V car battery ;P
<thefrog>
specing: I usually have a bunch of 7Ah 12V laying around. My UPSs eat them though
revident has quit [Quit: Combustible lemons? Bah, I bring you weaponized asparagus!]
<thefrog>
mmm asparagus
<specing>
What do you mean they eat them?
<specing>
they die in a short time?
<thefrog>
specing: yes. They die in a short time... probably every 10 months.
<thefrog>
was thinking of getting one of those pulse chargers to see if they could be renewed
<specing>
That is because most of the UPSs on the market are designed to pump out as much power as possible for as much as possible
<thefrog>
I've been wondering about the charging circuit. They spend most of their time fully charged
<specing>
My design would let it discharge to percentage of their capacity before charging again
<specing>
So when power fails for 3s they don't start charging like mad again
<thefrog>
that'd be a good idea.. i';d like to stay on UPS for a minute or two after a drop
<thefrog>
The typical AC power loss is off for a few seconds.. restore for a few seconds.. off for a few seconds
<specing>
Well the thing can be interfaced though serial,usb,I2C(think VGA),SPI,etc,etc
<thefrog>
actually.. and undervolt.. then a loss.. then a breaker at the utility tries to restore the leg.. if your leg has the short.. undervolt.. another loss. Probably down for good
<specing>
So you could have all the machinery go to sleep within the first second of the failure
<thefrog>
I'd be interested in monitoring my power output on each voltage output.
<thefrog>
i donno why. Too much mrtg/cacti in my past i guess
<specing>
Such projects already exist
<thefrog>
most of the SNMP on the UPSs is really bad.. and as far as controlling behavior (Mains Power settle period for example) is non-existant
<thefrog>
specing: when you say "discharge to a percentage of their power before charging" how do you plan to do that and maintain runtime?
<thefrog>
are you going to cycle through banks?
<specing>
My goal is not to maintain runtime
<thefrog>
(banks of battery)
<thefrog>
ah.
<specing>
It is to maintain the life of the battery
<specing>
as I said, the thing can inform a daemon listening on the computer it is interfaced to and it can standby the machine
<thefrog>
Couldn't you switch to pulse charging to maintain the life of the battery?
<Turl>
aren't all those batteries trickle charged?
<specing>
Well anything is possible if it supported by the AVR's PWM
<specing>
I have only so far done trickle charging
<specing>
due to USB-supply's limits (500mA)
<thefrog>
i suspect the reasons that may batteries die is the trickle charging and the sulfide crystals that build up over time
<Turl>
most USBs made on this century can provide >500mA
<thefrog>
(lead acid)
<thefrog>
I can buy 2.1A USB power supplies from walmart for 8 USD.
<specing>
Turl: the other reason is that I had 10 other subjects to attend to :P
<Turl>
10? hah
<thefrog>
i was surprised by that
<Turl>

though it did count as the final project for CS

for lead acid.. Pulse charging keeps the batteries alive

it's almost never in a UPS though
