<Ixnus> this three solder pads on the back left side look two obvious
fl_0 has joined #linux-sunxi
<Ixnus> what are they?
<Ixnus> too*
<amw2320> Unclear. The only obvious solder pads are on the back of the board, and I thought I hit jackpot when I got to the ones you mention, but sadly there was no output.
<Ixnus> Maybe a person with A83T can help you more

<amw2320> any chance you know the answer to the sys_config.fex question?
<Ixnus> What kernel & u-boot you are trying?
<Ixnus> is some vendor BSP/SDK ?
<amw2320> exactly. the included vendor files.

<Ixnus> sorry, I can't help with fex.
<amw2320> no worries, thanks
<Ixnus> did you try fel ? Is the display working?
<amw2320> FEL works. Display doesn't show anything during FEL, but I can flash images.

I haven't tried to clock a 16550 with a different clock speed since the 90's when I soldered in a 24MHz XTAL to a board so that I could at least get up to 1.5Mb/s.

<rellla> hi, can someone help me to sum up what is status quo atm regarding mainline kernel and display? i feel, i like i don't get it :p
<rellla> A13/R8: drm->rgb/composite ok
<rellla> A10/20: drm->rgb (net147), drm->lvds (plaes)
<rellla> A10/20: simplefb->hdmi
<rellla> H3: drm->hdmi (moinejf)
<wens> rellla: for the old DE (1.0), the first RGB pipeline is supported, but you also need sunxi-ng ccu support for each SoC
Putti has joined #linux-sunxi
<wens> rellla: hdmi, native VGA (A10/A20), lvds are not there
scream has joined #linux-sunxi
<rellla> wens: thats sad...
<wens> rellla: it's just the way it is, we never did support the display clocks in the old sunxi clk driver
<rellla> what is needed for DE1.0->hdmi? the hdmi driver, i suppose :p
<wens> yes
<wens> same goes for all the other outputs
<rellla> i want to setup sth, where i can play with sunxi-cedrus and userspace things. therefore i need a display, preferably hdmi ...
<KotCzarny> simplefb works
<KotCzarny> for a20/h3
<rellla> KotCzarny: for the basics, this would be enough, for tweaking+vsync+... not, right?

<Pe3ucTop> willmore: I think serial is limited only by givem master clock, and it's /16 by controller itself, and it's the same chip/cmos/tehnological process, and @1.2Ghz max serial speed is 75Mhz and can be handled by in/out pins.
<scelestic> mh, it probably isnt related to sunxi but perhaps someone here knows where to point me then, i'm getting oom errors when running a du -sh / on my orange pi plus and afaik the machine should have enough memory, since i didnt think it was sunxi related i recreated my machine in virtualbox somewhere else and i cannot trigger it, i'm getting these errors: http://pastebin.com/Msrh2cVJ

<ElBarto> mripard: for A20 ?
<mripard> A10s at the moment
<mripard> but it should be the same controller
<ElBarto> they are the same iirc yes
<ElBarto> well maybe not, I never had hdmi output on FreeBSD on my A10 board and now that I know how to debug my board is dead :)
<ElBarto> while we support hdmi on A20
<KotCzarny> how did it die?
<ElBarto> I really don't know
<ElBarto> plugged it and nothing came up

<lovepupils> yes, I lurked the threads a bit on armbian forums. fortunately the main goal of the board for me will be a headless server, or rather a NAS + torrentbox and backups
<lovepupils> so video accel is not a priority for me
<lovepupils> I bought this board to substitute a raspi B+ which was choking when delivering high bitrate videos to a kodi box via nfs
<lovepupils> I hope the dedicated chip gigabit ethernet will help me, I saw promising iperf tests already

lkcl_ has quit [Ping timeout: 264 seconds]
<buZz> huh, 6 pin battery?
<cnxsoft> Well the poor guy has been trying to get the connector for more than 5 days...
<buZz> looks like JST-PH
<buZz> 1.25mm pitch?
<buZz> ttp://www.ebay.com/itm/Mini-JST-1-25-T-1-6-Pin-Connector-with-Wire-x-10-sets-/171361716307
<buZz> yep
<cnxsoft> Yes 1.25.. But no battery manufacturer sells a battery with that connector apparently, so you can to buy a battery, then cut its connector and replace it with the 6-pin connector.
<buZz> oh, no
<buZz> cnxsoft: soldering isnt rocket science, is it? :P
<cnxsoft> That's OK. but you wonder why they use that connector since there's just VDD and GND...
<jelle> cnxsoft: like your blog :)
<KotCzarny> cnxsoft: they got good deal on it?
<KotCzarny> ;)
<cnxsoft> Maybe, or just too much stock, they had to find some use, and then brilliant idea!: let's use it as a battery connector.
<buZz> or lack of experience
<KotCzarny> or moneygrubbing scheme!
<KotCzarny> though if that was the case they would've advertised it earlier
<cnxsoft> I remember in the past, the company has a bunch of SoC from a cancelled project (I think 50,000 or so), so we had to find a sucker, sorry customer, to use this and we created a project just to get rid off the stock.
<buZz> :D
popolon has joined #linux-sunxi
<cnxsoft> I meant "the company I worked for"
<MoeIcenowy> what SoC?
<jelle> MoeIcenowy: an arm board (system on chip)
<cnxsoft> I can't remember which one, some SoC used in DVD players
<cnxsoft> That was in 2004.

lkcl_ has quit [Ping timeout: 240 seconds]
<willmore> dgp, that was my thinking as well. There may be a limit that we just don't know about. ;(
<willmore> cnxsoft, why cut the connector off? If it has the right pins for the socket, but the wrong socket, just extract the pins from the socket and plug them into the new one. :)

<KotCzarny> for gpio/twm you would probably need more than 2 pins

<lovepupils> (it was barely usable, I just wanted to stress it a little)
<KotCzarny> that's because video decoding is done via specialized chip

<KotCzarny> he, he
<tkaiser> KotCzarny: Nope and nope
<KotCzarny> it will probably die in few seconds
<lovepupils> is it? i though gpu was not used yet since it's still stuck at 720 res and so on
<ErwinH> H5 currently won't run faster than 1008 MHz
Nyuutwo has joined #linux-sunxi
<KotCzarny> lovepupils: gpu != video decoder
<buZz> willmore: replugging pins would only work if its a similar connector
<buZz> willmore: you cant use molex pin in a JST plug, for instance
<tkaiser> lovepupils: try out cpuburn-a53 if you want to see high temperatures.
<KotCzarny> tkaiser, is there static build for android use?
<KotCzarny> unless there is linux image for h5 already?
<tkaiser> lovepupils: And at the moment I doubt you get HW accelerated video decoding with those Linux images.

IgorPec has quit [Ping timeout: 258 seconds]
<willmore> lovepupils, I wouldn't suggest hooking a fan directly to any I/O. I would strongly suggest using a transistor of some kind. You may also want to look into an electronics toutorial on controlling inductive loads.
<tkaiser> ErwinH: Settings unfortunately make somehow sense. H5 has an internal Ethernet PHY and if they simply leave out DVFS and limit clockspeed to 1008 MHz then H5 could be used on a small board without too much thermal hassles.
<willmore> So, would this zero plus 2 board have the silly regulator from the One or the real one from the PC?
<KotCzarny> silly
<willmore> Crud.
<KotCzarny> lol
<willmore> Well, as long as it has SPI NOR. :)
<KotCzarny> even more names
<willmore> Prima? Oww, I like that name. I have a friend of that name.
<ErwinH> That, or even no regulator at all, since the H5 is running fine at 1100mV @ 1008MHz.
DullTube has quit [Quit: Leaving]
<willmore> ErwinH, sure. Good point.
<KotCzarny> erwinh, yup, silly
<willmore> I'd like to see a tiny board with a tablet type power controller--with battery charge/monitoring support. Because you just know that a lot of these boards are going to get stuffed into battery powered situations and they'll just kludge some battery onto them.

<MoeIcenowy> can you test the CPUX clock adjusting on you A23 device?
<MoeIcenowy> I think A23 ccu needs also the clock notifier for PLL_CPUX adjusting
<MoeIcenowy> and also CLK_SET_RATE_PARENT for CPUX clock
<willmore> tkaiser, I'm not familiar with that chip. Is that the one on the CHIP?
<tkaiser> willmore: Nope, that's R8/A13. R16 is like A33 (quad-core A7). You could use this 'board' http://linux-sunxi.org/Nintendo_NES_Classic_Edition and throw the enclosure away (cheap stuff sold expensive)
<willmore> LOL, tkaiser.
<tkaiser> willmore: Even the 'usual' 6-pin battery header! http://linux-sunxi.org/Nintendo_NES_Classic_Edition#Adding_a_serial_port_.28voids_warranty.29
<willmore> Okay, that chip--just looked it up on the wiki. Interesting.
<willmore> That 6 pin connector doesn't look like it's for a battery. Really looks like a data connection.
IgorPec has joined #linux-sunxi
<tkaiser> willmore: Just kidding. But really, a lot of those small H3 boards would be better use R16 since... PMIC and battery support. But 've no idea how much R16+PMIC would increase costs (especially when having OPi Zero for $7 in mind)
<KotCzarny> hmm, which h3 board supports battery?
<MoeIcenowy> no, except you use a power bank
<tkaiser> KotCzarny: Exactly none. No PMIC, no battery
<MoeIcenowy> as power bank has a PMIC ;-)
<KotCzarny> there are external li-ion charger/power supplier boards though
<willmore> tkaiser, I realized you were kidding. :) And, yeah, I don't know how much that PMIC goes for. Clearly $7 is going to be a difficult target price. Still $12 for a board that's battery enable would entice those people who were going to try to graft a battery onto the $7 board.
<tkaiser> MoeIcenowy: But the you need a foto cell and monitor the led of the power bank if there's any.
<MoeIcenowy> tkaiser: ;-)
<MoeIcenowy> I'm doing nothing more than joking here ;-)

<dgp> rellla: Pretty sure the cords are too short for all 4 of my Japanese rooms..
* dgp suspects they meant one room apartment the size of a shoe box
<rellla> dgp :) haven't been in japan ever. sadly.
<willmore> MoeIcenowy, thanks. So, the H3/2 is 32 bit. That would make a good deal of performance diff in the right(wrong) situation.
<dgp> willmore: If you want performance you aren't going ARM in the first place really
<MoeIcenowy> I have seens someone want to get an A64 for doing some vector calculation with NEON ;-)
<dgp> A64 NEON is different to normal NEON?
<MoeIcenowy> A64 NEON is ARMv8 NEON.
<MoeIcenowy> ARMv8 NEON is richer ;-)
<dgp> Bigger registers? More of them?
<dgp> I thought the NEON registers were already bigger than 32bit
<MoeIcenowy> at least in ARMv8 NEON can be fully IEEE754-complicant
<Wizzup> MoeIcenowy: thank you!
<dgp> Faster than a old nvidia GPU for anything?
<MoeIcenowy> in ARMv7 it's not fully IEEE754-complicant
<MoeIcenowy> a old NVIDIA GPU is not embedded ;-)
<MoeIcenowy> and A64 is cheap
<MoeIcenowy> the only advantage of sunxi is cheap ;-)
<dgp> yeah, vendors with docs can't produce quad cores for <$5 :(
<willmore> dgp, IIRC, the actual ALU on v8 is 2x the width of the v7 one.
<willmore> ssvb, would be more authoritative on that than I.
<dgp> willmore: makes sense. Just glad it's in v8 and not yet another possible thing you can have on an v7 core
<KotCzarny> MoeIcenowy: also, low-power
<MoeIcenowy> I wonder if there is anyone trying to use a linux-rt on Allwinner SoCs ;-)
<MoeIcenowy> or anyone trying to use linux-libre ;-)
<dgp> If the openrisc has access to interrupts and other hardware blocks it would be interesting for doing realtime stuff..
<MoeIcenowy> but it has now not a SDK...
<MoeIcenowy> according to the wiki, it do have access to the hardware blocks
<dgp> OpenRisc has gcc etc support at least. Not something so weird you can't get a toolchain for it :)

<jski> have booted gentoo on the orangepi pc plus using the orangepi 3.4 kernel and my already working filesystem is not opening port 80 for lighttpd any ideas?
reinforce has joined #linux-sunxi
<jelle> your filesystem is not opening a port?
<jelle> jski: run 'ss -tulpn' and check for 80, check the firewall
<KotCzarny> i would bet for networking not working at all
<jski> network is working
<jski> ping / ssh all fine
<jski> even my apps open on ports
<KotCzarny> then check netstat -an|grep 80
<dgp> tcpdump
<jski> nothing for 80
<KotCzarny> then you have no httpd running
<jelle> does the default nginx even run on 80 :)
<KotCzarny> he uses lighthttpd
<jski> ah fcgi failing
<KotCzarny> also, you can have almost full featured mainline for h3 already
<jski> there must be something missing from my kernel :/
<jski> I am taking the rootfs from a board using 3.0.8 so 3.4 should be fine
<KotCzarny> still, glibc is usually compiled with some kernel headers

<hojnikb> KotCzarny: is there a sheet on what is working/non working on mainline h3 ?
<KotCzarny> yes
<KotCzarny> but there are patches below to enable those not-yet-mainlined things
cptG_ has quit [Read error: Connection reset by peer]
<scelestic> i suggest using megous' tree for h3
<scelestic> (at least working really well on my orange pi plus 2
<jonkerj> (on PC and Plus too)
<KotCzarny> those things are essentially the same :P
<KotCzarny> seriously, all h3 orange boards should be one board with bits added here or there
<jonkerj> sure, but that does not make them running less good on megous' tree
<hojnikb> what about display ?
<hojnikb> can you get hdmi output on mainline with patches ?
<jonkerj> megous' tree gives me boot messages about edid/hdmi and fb
<jonkerj> but have not checked it with hdmi connected
<scelestic> i dont have hdmi connected either so i dunno
<jonkerj> KotCzarny: I think the DT 'include hierarchy' for h3 opi* could do with some cleaning up

<KotCzarny> it would be great to enable devices/dt nodes AFTER boot too
<KotCzarny> then only nodes actually required to boot will have to be defined in uboot/kernel stage
<KotCzarny> as for display, if you only need simplefb, jernej's uboot already has hdmi enabled

<MoeIcenowy> KotCzarny: but I don't know anyone has simplefb node in device tree... except me
<MoeIcenowy> (I wrote the simplefb code ;-)
<KotCzarny> huh-huh
<KotCzarny> <not bad>
<MoeIcenowy> I found simplefb much more stable than moinejf's drm driver ;-)
<MoeIcenowy> and I now use it in half-production environment ;-)
<KotCzarny> because you can hardly go wrong with membuffer without any special ioctls? ;)
<MoeIcenowy> maybe
<KotCzarny> now steal neon accel ops and make turbosimplefb
<KotCzarny> *from ssvb
<MoeIcenowy> and the U-Boot HDMI driver has a better quality than moinejf's driver
<MoeIcenowy> especially EDID parts
<KotCzarny> i've found hdmi driver buggy with vga-hdmi converter
<KotCzarny> uboot sets fb to some format, then android kernel assumes it wrong
<KotCzarny> ie. pink screen and no audio, reconnecting cable fixes it
