Hi
<Jhon>
I'm new to sunxi linux
ZaEarl_ has joined #linux-sunxi
<Jhon>
Could somebody tell me how is the status of linux sunxi 3.4 kernel
<Jhon>
is it mature enough?
<Jhon>
or I should use 3.0 kernel instead
ZaEarl has quit [Ping timeout: 248 seconds]
<Turl>
Jhon: yes, 3.4 is recommended
<Jhon>
Thank you Turl. Another question: When use 3.4 kernel, do we still need any kind of .fex file? I think .fex file basically doing same work as device tree
<Turl>
yes, you need to load script.bin on both 3.0 and 3.4
<Jhon>
so this means device tree is not fully supported in sunxi 3.4 kernel right?
<Turl>
Jhon: it's not supported at all
<Turl>
Jhon: there is sunxi device tree support in mainline, but the hardware support is pretty limited at the moment
<Jhon>
ooo, ok. which branch should I checkout?
<Turl>
Jhon: for what? 3.4?
<Jhon>
yeah
<Turl>
sunxi-3.4 if I recall correctly
<Turl>
there's also stage/sunxi-3.4 with new changes that are currently being tested, if you want the bleeding edge
<Jhon>
Thank you very much, you helped alot

good night :)
<Jhon>
another question Turl: How frequently a new feature in stage/sunxi-3.4 being merged to sunxi-3.4 normally? just curious
<Turl>
Jhon: there's no predefined timeframe, usually once they've been sitting there for a while, mnemoc will merge the stage branch back into the non-stage branches, and possibly also merge any patches from mainline stable series
<Jhon>
so right now most of the people are working on 3.4 kernel I guess?
<Jhon>
good night too

I've figured out why fatload from nand doesn't work in aw sun6i u-boot, the internal functions in libnand uses the "wrong" function (they've added some new functions for that) to get the offset to the partition

oliv3r: there are many a10 devices out there and I don't think a10 is out of stock even if it is no longer manufactured. Don't be like the SoC makers and just stop considering any but the most cutting edge SoC
<oliv3r>
heheh, yeah but I wouldn't buy an a10 device unless its REALLY cheap and offers many connections
<oliv3r>
i mean, this a10 device is 80 USD
<oliv3r>
i can get a20 for less then that :)
<hramrach__>
depends on the other goodies, yes

sound a bit too much for a TV box but if it has some nice wireless keyboard you do not have yet it might be worth it
Black_Horseman has quit [Remote host closed the connection]
<hramrach__>
and the TV boxes tend to be more expensive than plain sticks - more connectors, bigger pcb, bigger case, fewer per container so bigger shipping costs
<oliv3r>
does it come with the keyboard?
<oliv3r>
melee is cheaper
<oliv3r>
it doesn't come with a keyboard, just a regular remote
<hramrach__>
sure, you can. when the atmega does nothing else
<hramrach__>
but you cannot do sound output and ethernet on an atmega at the same time because when an ethernet frame arrives the sound skips
<hramrach__>
or so I heard from a very disgruntled hw hacker
<wingrime>
hramrach; once I saw device with 8 atmega
<wingrime>
8xatmeaga8
<hramrach__>
that's why sound cards have buffers, serial ports have buffers, ethernet cards have buffers, graphics cards have built-in scanout dacs, all independent of the CPU delivering every single bit on time
<hramrach__>
when you have 8x atmega you effectively create those independent buffers ;-)
<hramrach__>
and yes, the displ layer should be quite capable when dealing with multiple outputs, just don't have any means to test that myself.
<wingrime>
anyone tryed make fm-transmitter using single GPIO on a10
rz2k has joined #linux-sunxi
<hramrach__>
heh, would be funny to make video sync line in software. every time you write non-trivial amount of data to disk the display blanks :DD
<hramrach__>
because Linux MM in recent kernels is junk and it takes 100% cpu time figuring out how to free memory when it's full of dirty buffers and even fails
<wingrime>
hramrach: why bliks , you can use timers and non maskable irq

wingrime: the wiki needs a lot of work; but
<oliv3r>
wingrime: having the register tables is nasty, ideally, we want to have a template, that reads a table of register data, and outputs pretty tables
<oliv3r>
wingrime: if you are referring to a13 vs a10 with the PWM, i wrote those pages when we had the a10 user manual, i never read the a13 manual and added those changes
<wingrime>
olvi3r: hw very same
<wingrime>
olvi3r: we need one page for one deivce with differences in page

hi folks, my microSD breakout board arrived today. I Have been using it in conjunction with my bus pirate but when i boot my devicce i dont get any console or text comming from the device i have the breakoutboard connected to. I had read a few weeks back that i may need to modify my script.bin to add uart support.
<sud0x3>
Could anyone shed some light on editing myu scipt.bin for uart? I have been looking through the fex file myself today and there are allready UART configurations in place
naobsd has joined #linux-sunxi
<wingrime>
oliv3r: have we audio hw decoder?
sud0x3 has quit [Quit: Leaving]
<oliv3r>
wingrime: if your asking if cedarX can do audio hardware decoding, i don't know. I was hoping we could offload some audio decoding (idct)
<oliv3r>
but with neon and thumb, it should be not a lot of burden on the CPU
sud0x3 has joined #linux-sunxi
<oliv3r>
wingrime: one page per device also means we have a lot of duplication (in the case of pwm), pwm0 is identical, pwm1 is just 1 additional register
<oliv3r>
which means we have to maintain both pages for updates to pwm0
<oliv3r>
but we have official manuals now, so the need is lower
<oliv3r>
so far i've added each component i'm working on to the wiki
<atiti>
did anyone play around with the cedarX h264 decoding?
<sud0x3>
yes i converted the file to fex and modified the parameters, then i converted the fex back to bin, mounted nanda as a folder on my sdcard, removed old script.bin replaced with new script.bin
<sud0x3>
now my device wont even boot i will flash back to stock using livesuit and try again

I tried to use the latest 3.4 kernel on an A10 with a 1280x1024 monitor and got this message (and a blank screen) disp_clk: Could not find a matching pll-freq for 26150000 pclk
<jlj>
is that a known issue?
<jlj>
seems like the edid code worked otherwise
<wingrime>
you can avoid using edid
<wingrime>
just configure cmdline for it
<jlj>
would that bypass the disp_clk error?
<jlj>
I'm not really sure what it means..

mnemoc: ok
<mnemoc>
but next week i'll get a new server where to migrate everything (4x the current and paid by friend ad-eternum). we can discuss how to layout things better then
<Turl>
mnemoc: all cleared on that? :)

hetzner been annoying with paperwork because it seems to be their first .cl customer

jlj has quit [Ping timeout: 246 seconds]
<mnemoc>
oliv3r: yes. the current server is paid (by me) until july 26. the next server is for the webshop of an school friend, and allowed us to do whatever we want with the hardware as long as it doesn't affect his ~150 product shop with a 100E/M budget
<mnemoc>
the machine has 4x1.5TB, i7 980 and 24GB of ram
<mnemoc>
plenty for his shop, the sunxi server and a "limited" build server
<mnemoc>
and free
<mnemoc>
building that shop will all so be first $work$ after leaving .es
<mnemoc>
but that's another story
<mnemoc>
moving the lxc guests shouldn't be problematic
<mnemoc>
and we will be able to get rid of that f* 3xraid1 + btrfs
<mnemoc>
in favour of raid10 + reliable fs
<mnemoc>
oliv3r: i have to admit i didn't expect to need to migrate it again, but it's a good oportunity to do things better this time
