my take on the 'speaker box' using bpi-m1
<KotCzarny>
its loud enough for normal use (i rarely turn it to full)
<MoeIcenowy>
let's imagine how a audio box can make use of A33/R16's quad core
<KotCzarny>
the only use of additional power would be running some icecast server too

or visualisations
<KotCzarny>
but that can eat as many cycles as you can throw at it
<MoeIcenowy>
the product is still not started to be sold

MoeIcenowy: samsung introduced 8GB LPDDR4 chips and they also have 128 GB eMMC chips (for automotive). I really wonder how the car audio players can use all that capacity
IgorPec has joined #linux-sunxi
<KotCzarny>
miasma: one word, pr0n
<miasma>
yea, maybe the flash space, but video playback won't need 8 GB of RAM
<KotCzarny>
sure, unless you wanted to run windoze on that
<miasma>
I thought samsung was supposed to use this compact tiny EFL GUI with Tizen. now, the machines are so powerful they can run any toolkit
<KotCzarny>
with big map data cached
<miasma>
heh
<miasma>
e-book readers also have 512-1024 MB of RAM. the pages need around 40 kB once rendered
<KotCzarny>
cache, also, hd display needs a bit of ram too
<KotCzarny>
color page rendered at full hd? and one or more pages cached?
<miasma>
sure. the ebook readers have 4 bit graphics
<miasma>
so it won't use much space even if its hd
<miasma>
they can also use lz4 if they want
<KotCzarny>
NOW they do
<KotCzarny>
but people want color
<miasma>
sure
<KotCzarny>
trust me, people will use as much ram as they can
<KotCzarny>
also, ebook reader can run other apps too
<miasma>
the ones with android yes
<miasma>
the others don't have much apps
<KotCzarny>
it never was 'oh, its enough', but 'lets see if we can have an edge over competition'
<wens>
your browser will use as much ram as it can :p
<KotCzarny>
who ever though about smartphones in the pre-cellular era?
<KotCzarny>
+1 wens
<KotCzarny>
any moderately complicated web page can easily eat 1gb of ram
<KotCzarny>
sad times
<miasma>
yea that's true
<miasma>
well, kindle and kobo are probably among the most popular models. they only have experimental browsers
<KotCzarny>
yet, i'm still using nokia n900 with 256M of ram
<KotCzarny>
and similarly im using some cheap ereader (low mem, but with eink carta display)
<miasma>
another funny thing is, pebble time smart watch has a 100 MHz arm cortex m4 and it can sustain smooth animation at several frames per second. the resolution is only 144x168 but they have 6 bit graphics. on ebook readers they even have 1 GHz CPU (cortex a7/a9 or so) and can't play animation at 0.2 fps
<KotCzarny>
thats because of the screen
<KotCzarny>
eink is slow
<miasma>
pebble time has also eink
<KotCzarny>
is it regular eink?
<miasma>
i'm not sure. at least it doesn't draw much energy
<miasma>
a 150 mAh battery lasts for a week
<miasma>
on my phone a 3000 mAh battery lasts for a day
<KotCzarny>
different use cases
<miasma>
anyway, the cpu power is ridiculous on that device, yet it can almost play smoother animations than my oneplus 2 phone
<JohnDoe_71Rus>
redraw 144x168 or 800x600 differett time?
<miasma>
that nook touch has 800 MHz TI OMAP 3621. I watched another video and it boots in around 30 seconds. my 700 MHz RPi model b (ARMv6) boots to X or Kodi in around 25 seconds.
<miasma>
and I didn't even use any optimized embedded distro

In fact I think my A33 tablet came with 512MB RAM is not acceptable
<MoeIcenowy>
so does Orange Pi One/Lite (
<KotCzarny>
they have their uses
<MoeIcenowy>
yes...
<KotCzarny>
as long it doesnt require web browsing
<KotCzarny>
512MB is plenty
<MoeIcenowy>
I know someone use 256MB RAM Nano Pi NEO to do some web forwarding

they need good caches in the front though for anything big

rah: can't you just use an existing defconfig which defines CONFIG_MACH_SUN4I=y and adjust this?
<apritzel>
rah: the defconfigs are not really complicated, it should be really straightforward to change one to match your board
<MoeIcenowy>
apritzel: have you tried my ice-a64-v6.1 tree?
<apritzel>
MoeIcenowy: not yet, looking into it later today
<apritzel>
MoeIcenowy: does OTG work for you?
<apritzel>
or is it just OTG host mode?
<MoeIcenowy>
just host
<MoeIcenowy>
Switching USB-A port to gadget mode seems to need more patches
<apritzel>
and thanks for using the right repo now ;-)
<apritzel>
fetching from your other one wanted to pull in tons of crap patches ;-)

ssvb: I'm currently experimenting with Windows-based builds of sunxi-tools. the autoversion.sh doesn't seem to be much of a problem as long as a POSIX-like shell or build system is available
<NiteHawk>
for MS compilers (MSVC) we'd probably have to provide a batch file, however

I'd favor getting the version information (output) in - i.e. merge #62 - before tagging a new release, what's your take on that?

CONFIG_DRAM_CLK=480

CONFIG_AXP_ALDO3_VOLT=2800 O_o

is not sure this is such a good idea
<as0d70apf>
lets hope volt is actually milivolt ;)
<apritzel>
rah: isn't there some board already which is close? the linux-sunxi Wiki page mentions some similar model, maybe that is supported already?
<apritzel>
rah: but well, that's what I meant with adjusting: you would need to find the right values for your board/tablet
<apritzel>
rah: DRAM clk and CPU clk are not overly critical (in terms of frying the board)
<apritzel>
so I'd learn what ALDO3 is used for - both in your and other boards
<apritzel>
maybe you don't need it at all and can disable it
Da_Coynul has quit [Quit: My Mac has gone to sleep. ZZZzzz…]
<apritzel>
rah: check the AXP manual for typical usage of ALDO3 (AVCC for instance?), also check your existing board config file script.bin/.fex
<rah>
well, basically, the answer is "no", it isn't particularly straightforward

NiteHawk: thanks for experimenting with the windows build, and it's nice to know that there are no problems with using shell scripts there
<NiteHawk>
ssvb: I'm actually slightly surprised that things go relatively smooth there - i can even see that we might provide precompiled win32 binaries in the future
