zerotri: are you asking binary, not source, right?
<zerotri>
building the source they released for r16 uboot
<zerotri>
I was having trouble getting it built but it seems that was related to gcc version
<naobsd>
I heard it can be built, but I didn't try. my interest is mainline.
fire219|BAMA is now known as fire219
<naobsd>
well, more accurately, "analysis for mainline"
<fire219>
does the NES classic board even have a UART out to pads? if it doesn't, that combined with basically no interfaces except controller would probably make development an exercise in frustration
<fire219>
not that i'm trying to discourage anyone :)
<zerotri>
Yes it does
<fire219>
well at least nintendo has some generosity
<zerotri>
Also holding the RESET button on boot goes to FEL mode

So they didn't try nearly as hard to close the system off

hello peeps. I have a cubietruck here with a very old uboot that can't see the mmc (and doesn't have USB/SCSI/network). I have managed to use fel to boot a uboot on mmc, and thus install debian onto HD. But I can;t work out how to write the updated u-boot to flash so it boots without going via fel mode.

OPi PC2 is at least cheaper, has faster Ethernet and more USB performance

ssvb: yes the ethernet i would consider this a killer feature too, but seeing the Pine64 disaster people seem to be ok with 100Mbit NICs ..

Afternoon guys
<terra854>
Any updates on A64 mainlining effort?
<MoeIcenowy>
terra854: sun50i-ccu-a64, pine64 support merged into 4.10 (linux-next now)
<tkaiser>
huawei: Twice the performance in some areas (NEON for example) compared to the PC, GbE instead of Fast Ethernet, everything else remainds the same (ah, SPI flash to boot from!)
<terra854>
So what is left for feature complete A64 support?
<MoeIcenowy>
terra854: many things
<MoeIcenowy>
fully support the USB PHY and MMC
<huawei>
tkaiser, nice
<MoeIcenowy>
I mean the full support is TODO
<MoeIcenowy>
huawei: I bought one opi pc2
<terra854>
So linux will run properly on the A64 with next-20161111 from kernel.org?
<huawei>
MoeIcenowy, it seems that no available image to use
<MoeIcenowy>
terra854: no, mmc support still not good
<MoeIcenowy>
huawei: we are WIP on it
<terra854>
mmc as in sd card support?
<MoeIcenowy>
terra854: yes
<tkaiser>
terra854: 'The Mali' doesn't work with mainline. It's unusable anyway
<terra854>
Oh I see, cause I would really like to give it a go
<terra854>
the kernel i mean
<MoeIcenowy>
and DE2 support is WIP in both kernel and u-boot
<terra854>
tkaiser: I know that, it is next to impossible given the slow progress of the lima project
<KotCzarny>
there is no progress of the lima project
* terra854
wonders if the lima project is still on...
<terra854>
I think it is dead
<KotCzarny>
nope, its on hold
<tkaiser>
terra854: Nope, it seems you're just infected by 'the Mali' hype as so many pour souls over there in Pine64 land
<KotCzarny>
because people decided they dont care about blobs and open source
<terra854>
MoeIcenowy: DE2?
<longsleep>
well why does anyone need graphics output on any of those boards, i do not get it
<MoeIcenowy>
KotCzarny: the 2nd generation of Allwinner Display Engine
<longsleep>
if mmc is there and works then its good enough imho
<MoeIcenowy>
used in A83T, H3, A64, H5
<KotCzarny>
longsleep: because it makes nice to be able to use terminal and other apps?
<longsleep>
KotCzarny: mhm use for what?
Putti has quit [Ping timeout: 260 seconds]
<longsleep>
i do not see a real use case
<KotCzarny>
general computer
<terra854>
longsleep: Well, I think everyone is drawn to the fact that the PineA64 will be a good and cheap media center
<tkaiser>
longsleep: Because people really trust in marketing and think they could buy a 'supercomputer' for $15
<KotCzarny>
cheap, quite, cold
<KotCzarny>
*quiet
<longsleep>
media center, use android
<KotCzarny>
low power, always-on
<KotCzarny>
nah.
<KotCzarny>
i prefer linux
<longsleep>
and regarding desktop environment, you need a browser eventually and they all totally suck on arm64
<longsleep>
also with 2GB ram, thats not enougth for anything serious
<tkaiser>
longsleep: apt install firefox:armhf ;) And then suffering from slow random IO on SD card
<KotCzarny>
i still have to check if firefox running with .profile in tmpfs works any better
<longsleep>
really i do not see the use
<longsleep>
tkaiser: sure, but still no fun in that
<tkaiser>
longsleep: Exactly, it feels PITA.
<terra854>
And none of the major browsers use vdpau
<longsleep>
for a desktop one needs fast graphics output with video decoding in browser, webgl and gpu accellerated compositing
<longsleep>
if you do not have that it just sucks
<longsleep>
and no point in even trying
<terra854>
That's where the Mali comes in for compositing (which will never happen)
<terra854>
and vdpau support in the major browser
<ssvb>
terra854: first, if you really want, then you can use the mali blob
<longsleep>
so, for the OPi PC 2, it has only 1GB ram but 4 USB and 1000M NIC, so what to do with it which actually is not pita
<tkaiser>
longsleep: OPi PC 2 could be interesting for classrooms as remote graphics terminal since GbE is the fastest interface
<ssvb>
terra854: second, compositing only *reduces* performance, while providing nice eye candy effects
Putti has joined #linux-sunxi
<longsleep>
tkaiser: ok thats interesting, but isnt 100M enough for that? so why not use a RPi3 instead
<terra854>
ethernet over usb. that's why
<tkaiser>
longsleep: please keep in mind that I'm biased doing network stuff with 10GbE, Fast Ethernet feels almost broken ;)
<ssvb>
longsleep: is video decoding needed in the browser for youtube?
<tkaiser>
ssvb: Seems there exist 'hacks' like smtube
<longsleep>
tkaiser: yes i understand that, but for 1080p with a suitable screen codec 100M is plenty
<longsleep>
ssvb: yes
<longsleep>
ssvb: if you want to go above 480p
<longsleep>
ssvb: and even the, check chrome://gpu/ in any chromium based browser to see what they all use the whatever hardware for to make things faster
alexxei has quit [Read error: Connection reset by peer]
<miasma>
tkaiser: the nx protocol works over 512kb adsl. remote X is pretty bloated. you should be able to do remote desktop stuff with 100M
<ssvb>
longsleep: we have talked about this before, there is no technical issue to have hardware accelerated video decoding in browsers
<longsleep>
ssvb: yes, but my point is that even if it would work the usefulnes is doubtful imho and thus not worth the efford
<longsleep>
ssvb: i mean Google does it all for android, so why not use it
<ssvb>
longsleep: just the open source wankers can't agree which of many possible ways to do it would be preferable
<ssvb>
but any commercial product can achieve this with a little bit of patching
<longsleep>
right
<longsleep>
i think for the OPi PC 2 a non desktop use case needs to be found
<longsleep>
without it, the board is just another one in our shelfes
<longsleep>

Is there any nmajor differences between the H5 and the A64 (besides the difference in the number of GPU cores)?
<longsleep>
it workes really nice
<longsleep>
but he board is quite large
<MoeIcenowy>
terra854: pinout
<longsleep>
so the pc 2 is smaller, but onlky 1 GB ram
<longsleep>
only
<MoeIcenowy>
standard pmu (H5 do not suit a pmu, A64 suits AXP809)
<terra854>
So we can use AXPxxx with the H5?
<terra854>
*can't
<longsleep>
so lets say for example, can we use the H3 based PC2 to make a decent host for zfs even if it has no ecc?
<tkaiser>
longsleep: My use case is NAS for unimportant stuff, being able to spindown a couple of disks individually and use btrfs with it. No ECC --> no important data
<longsleep>
tkaiser: right, but what about network storage for your docker images or vms it would be nice if one of the hosts in the fleet could provide that at reasonable performance
<tkaiser>
longsleep: And to be honest, we replaced a few larger x86 NAS boxes with GbE H3 boards and 3 x 64 GB flash. Used a weird mixture of mdraid and btrfs mirror and performance was quite ok (better than the expensive NAS boxes with 40-50 TB each). Special use case but you could do this with UASP enabled disks on PC 2 too

tkaiser: yes thats what i am thinking
matthias_bgg has joined #linux-sunxi
matthias_bgg has quit [Remote host closed the connection]

matthias_bgg has joined #linux-sunxi
<MoeIcenowy>
jernej: have you compared the disassembly?
<longsleep>
tkaiser: right now i am thinking to concentrate on the Orange Pi Zero, that seems to have more use cases as its very small and has wifi and potentially PoE
<tkaiser>
longsleep: Sure, but there's nothing left to be done when MoeIcenowy ported Wi-Fi driver to mainline ;)
<longsleep>
tkaiser: i mean software wise - get Ubuntu Snappy for it
<tkaiser>
longsleep: Ah, ok
<MoeIcenowy>
to really make it enter mainline it needs a rewrite'
<MoeIcenowy>
what I say "port" just means make it work on newest kernel
<longsleep>
MoeIcenowy: that would be enough for my needs :)
<MoeIcenowy>
then I found I'm not familiar with nl80211...
<jernej>
MoeIcenowy: Not in the detail.

Was hoping allwinner have USB 3.1 support in their SoCs
<tkaiser>
terra854: Allwinner isn't developing SBC, their markets are different. It's all about 'as cheap as possible' and some business unit weirdness (see this Nintendo thingie, using R16 there is just brain-dead)
<tkaiser>
longsleep: is there already a place to discuss Snappy/Core issues for Orange Pi Zero? Ubuntu forums?

MoeIcenowy: But where's the point to use PMIC without battery and a SoC that needs an external component to provide HDMI and audio output? H2+ would've been the better choice.
<MoeIcenowy>
good problem ;-)
<BurtyB>
maybe the H2+ wasn't around when they started work on it?
<tkaiser>
TL Lim said when he decided against R18 and switched to A64 some people at Allwinner were really angry
fkluknav has quit [Remote host closed the connection]
<tkaiser>
BurtyB: Doesn't matter since H2+ is just a crippled H3. But H is not R (different BUs)
<terra854>
R18?
<tkaiser>
terra854: Same as A64 with different chip id. Same SoC, different BU, different software development teams. At least that's my impression
<terra854>
BU?
<tkaiser>
terra854: And R18 is real, first pictures of Pine64 board were with R18 on it. BU == business unit
<MoeIcenowy>
if chip id is different then we cannot say it's same chip
<tkaiser>
MoeIcenowy: Maybe, I just played around with A83T and H8 back then and all that was needed to get Allwinner's stuff to boot was exchanging one blob otherwise I got a weird message
<tkaiser>
And I would assume the same SoC is now also called R58, V66, T8 and maybe tomorrow has another 5 names
<terra854>
Just noticed that Allwinner has so many SoCs
<tkaiser>
terra854: They have so many names but just a few SoCs
<terra854>
but in the end they are almost the same
matthias_bgg has quit [Quit: Leaving]
<terra854>
tkaiser: Yeah. Some of the SoCs are identical, they just changed the names only
<terra854>
Marketing purposes i guess
<MoeIcenowy>
now in the allwinner world, a soc, when come with Tina, it's R; when come with tablet UI android, it's A, when come with OTT UI android, it's H, when come with IVI UI android, it's T ;-)
<tkaiser>
terra854: We don't know for sure if there aren't real changes, for example R58 is supposed to be paired with a different PMIC than H8 and A83T (IIRC). And these different chip ids are for market segmentation if I understood correctly. Allwinner customers relying on their software offerings get Android 4.4 max for H8 while being 'allowed' to run 5.1 on A83T
<MoeIcenowy>
but now no one prefer to use A64 as tablet SoC...
<tkaiser>
Would be interesting what they think about the community Android 7.0 port to A64 (since their own offerings end with 6.0)
<BurtyB>
all they need now is a W so you can spell wrath ;)
<MoeIcenowy>
All current known Allwinner chips will end with Marshmallow
<MoeIcenowy>
Nougat's CTS needs GLES 3.2, which cannot be provided by Mali Utgard
<terra854>
tkaiser: Well, from what I heard, it's getting better every day
<MoeIcenowy>
and allwinner is now even making wifi cards...
<tkaiser>
terra854: See MoeIcenowy's answer, if GPU doesn't meet specs then...
<terra854>
I know. I saw it
<MoeIcenowy>
I wonder what will be done by aw
<MoeIcenowy>
purchase Mali Bifrost/Midgard or keep the Android ver @ 6.0
<MoeIcenowy>
Oh I forgot that A83T uses PVR GPU
<tkaiser>
terra854: On the other hand I really don't understand Pine64 users keen on Android. They buy a board, a battery, a really crappy LCD, an ugly/bulky enclosure, assemble this stuff to an ugly beast, use a crappy SD card just to get worst Android experience ever. While on aliexpress they could get A64 tablets for half the price
<MoeIcenowy>
is there A64 tablets now?
massi has quit [Remote host closed the connection]
<tkaiser>
MoeIcenowy: Sure, even 'hybrids' with keyboard and trackpad

tkaiser, how are you powering those drives? usb port only or external dc-in?
<tkaiser>
KotCzarny: Depends. I've one Samsung SSD (an OEM) that kills almost every SBC when host-powered. But normally SSDs are fine. And 3.5" are always powered externally. Simply look into datasheets for peak / spinup consumption. That's all that matters.
<tkaiser>
Most recent 2.5" have pretty low spinup power requirements

KotCzarny: Which is why I bought on amazon.de ;)

KotCzarny: google --> jms567 site:amazon.de
<tkaiser>
Or 152d 0567 site:$seller-of-choice
<KotCzarny>
or just particular enclosure model. ie inateck fe2006
<tkaiser>
KotCzarny: Works with Inateck or StarTech but not with others
<KotCzarny>
which ones do you own?

Neither nor ;)

I have 'CSL' and 'ICY BOX' (raidsonic)
<tkaiser>
Seriously: buy something you can return and test. Everything else is a huge waste of time
<KotCzarny>
uhum.

With Raidsonic googling works mostly but they had one model where they exchanged silently a crap chipset with a good one without changing product name. But that was years ago
<KotCzarny>
unfunny part of buying electronics is lack of technical details often
<KotCzarny>
maybe i'll just to into local store and start opening enclosures
<tkaiser>
KotCzarny: So why not buying stuff that mentions technical details? And then return stuff if it's not the case? Checking USB vendor/device id is ok (unless it's ASMedia inside ;) )

icy box ib-25[345]u3 seems to support uasp. cant find what chipset they have though
<KotCzarny>
local store has them for ~15eur

tkaiser, apparently newer chip jms578 allows trim passthrough
<tkaiser>
KotCzarny: Thanks, now we just need someone providing an OPi Zero 'HAT' using two JMS578, the two exposed USB2.0 ports on Zero's 13-pin header and providing two mSATA slots. Then people can start to play pocket RAID ;)

well, jmicron says their chips support port-multipliers, *hint* *hint*

Naobsd: able to pull things from NAND but still no luck getting console in Linux

KotCzarny: PM means shared bandwidth. And those JMicron PMs (especially those playing RAID) aren't that great.
<KotCzarny>
yeah, i was just kidding. i wonder if xunlong could simply use jms567 or 578 instead of crappy gl830
<tkaiser>
KotCzarny: I know, and what's quite surprising is the power consumption according to specs.
<KotCzarny>
its only motor start that was a problem in old drives, newer with soft start are fine

Hi. An universal touch screen controller with an universal screen converter can be the best way to connect a touchscreen on board ? I try to find somethign interesting for the cubieboard2 but there is really nothing dedicated for it. All I can find is for raspberry

KotCzarny: that drive is pretty awesome, but i guess the radom write throughput won't be good if it's a SMR drive. i have the 1TB version
<miasma>
oh wait, i have seagate

what good is drive if you cant connect it to your board
paulk-collins has joined #linux-sunxi
<miasma>
KotCzarny: what drive you can't connect ?
<KotCzarny>
any drive
<KotCzarny>
while my banana has no problem with the drive connected to sata port, from 2 usb-sata adapters one is recently failing (general usb disconnects that require replugging)
<miasma>
is it a powering issue
<KotCzarny>
im afraid to bump the voltage on my psu too much
<KotCzarny>
maybe i should switch to powering it via gpio
<KotCzarny>
but i dont know if its safe on bpi-r1
<miasma>
mm
<miasma>
do you have one of those usb power meters?
cptG_ has joined #linux-sunxi
<miasma>
it might show if the voltage is dropping
<miasma>
i guess the bus could support 5.2 (or maybe even 5.5V)
<KotCzarny>
i have li-ion battery connected
<miasma>
ah ok
<KotCzarny>
and i haven't studied power routing
<miasma>
and after that some dc-dc supply?
<miasma>
li-ion is 3.7V no?
<KotCzarny>
nope, its connected to battery port on the board
<miasma>
um.. maybe the board has a voltage converter
<KotCzarny>
a10/a20 boards featured battery ports and axp209 is able to charge/use it
<miasma>
right, but it probably needs to change the voltage for usb
<KotCzarny>
can you read board power schematics?
<KotCzarny>
all i need to know is if gpio 5v is directly connected to dc-in
<KotCzarny>
hmm
<KotCzarny>
or to sata-power port

i think i read about that stuff (banana pro) in some banana pi forums
<miasma>
iirc they weren't able to do it via gpios
<KotCzarny>
bpi-r1 is a bit different beast
<miasma>
i tested my seagate 1TB mobile drive (smr hdd) with 5V/100mA from my usb keyb. it didn't power on
<miasma>
the motor started spinning, but it tries to spin up in a loop
