<eagles0513875> hey guys
<eagles0513875> quick question is the pine64 board an all winner based SOC
<adj_> eagles0513875, it seems to be allwinner r18
<eagles0513875> adj_: thanks
<adj_> but should be them who makes clear what soc it uses
<eagles0513875> adj_: ok reason im asking is that i have a friend who has ordered one and he wants to know how to get things installed on it
RonWhoCares has joined #linux-sunxi
<eagles0513875> adj_: any chance you can link RonWhoCares to a guide on how to get things going in terms of booting with the pine64?
<adj_> eagles0513875, don't expect a lot of support when the device is released
<eagles0513875> adj_: why do you say that?
<eagles0513875> RonWhoCares: why do you want the pine 64?
<adj_> there is not even a page about the r18 in linux-sunxi
<eagles0513875> got it :)
<adj_> eagles0513875, do you know what hardware has the r18 inside?
<eagles0513875> adj_: no this is the first im hearing of it
<RonWhoCares> eagles0513875 Remember the comments I made about my health? I am trying to avoid the utilities in my home from being disconnected and then going bankrupt. But I need a separate computer for video editing / rendering. With serious financial constraints this is the most practical answer.
<eagles0513875> RonWhoCares: understood but with this device what adj_ is saying is its a really new processor alot of embedded systems are still 32bit in terms of ARM based cpu's
<eagles0513875> RonWhoCares: what kind of budget are you talking about for such a device?
<adj_> my advice is to buy a system with a known good support
<eagles0513875> adj_: was about to suggest the raspberry pi2
<adj_> for allwinner, probably a system based on A20 is a more secure bet
<eagles0513875> ya then adj_ a cubieboard 2 as that is what I have
<RonWhoCares> 'Pine 64' is 64 bit based
<eagles0513875> adj_: i still cant wrap my head around the complexity of getting a linux distro setup on it
<eagles0513875> RonWhoCares: whats the advantage of 64bit
<eagles0513875> these embedded systems 64bit is still super new
<RonWhoCares> eagles0513875 It is suppose to increase performance
<eagles0513875> RonWhoCares: on a normal pc has it really improved performance?
<RonWhoCares> I've had better experience with 64 bit systems
<eagles0513875> RonWhoCares: in terms of embedded systems its the other way around actually
<eagles0513875> you will spend more time getting things working and getting the kernel patched etc for it to work with that processor
<RonWhoCares> I've already mail ordered a 256 gig microsd card
<RonWhoCares> 256 gig is the maximum size the pine 64 runs on
<eagles0513875> RonWhoCares: actually thats super nice
<eagles0513875> do you know how to code?
<RonWhoCares> Yes I do. PHP , pgSQL and Zend Framework
<eagles0513875> RonWhoCares: you will need to learn c/c++ to do some kernel hacking to get things working for that chip
<RonWhoCares> eagles0513875 I can't put the time into this
<eagles0513875> what we are trying to say out of the box at this stage with 64bit embedded systems they are not common
<RonWhoCares> eagles0513875 I was originally on #lubuntu (where I met phillw)
<RonWhoCares> The FAQ for this computer says this operating system is suport
<eagles0513875> RonWhoCares: you wont know until you give it a try
<adj_> RonWhoCares, I don't understand you. You said that you had financial constraints
<RonWhoCares> I watched a 'Youtube' video showing a demo unit showing Ubuntu
<adj_> but you are talking about a device that is actually in crowdfunding campaign
<adj_> and you already bought an expensive sdcard for it...
<RonWhoCares> adj_: There is a lot going on in my life
<RonWhoCares> The microSD card wasn't expensive
<adj_> 7.5$ for a 256GB sd card?
<eagles0513875> canadian dollars there adj_
<adj_> it says 7.50USD
<adj_> 10.42 canadian dollars
<eagles0513875> adj_: still not expensive at all
<adj_> the cheapest 256GB sd card on newegg is 75$, and the others 125$+
<adj_> 7.5 sound as scam
<eagles0513875> adj_: dont underestimate ebay
<eagles0513875> i bought a 400 dollar handbag for my sister for xmas for around 83GBP off ebay and that is including shipping

<eagles0513875> paypal after waiting 3 weeks to hear back from him why the item wasnt shipped etc gave me my money back

<silviop> Hi, my ask: Tablet q8 A13 compatible, Uboot start with working lcd and backlight, after p 2 second pause start kernel,then backlight switch off, but i can see with a flashlight kernel boot text scrolling so lcd is ok but backlight is switched off, uboot and kernel are mainline versione (2016 rc2 and 4.x).I try to set default-.brightness-level =<100> in sun5i-q8-common.dtsi but no change.In my original fex lcd is enabled by
<silviop> AXP-0. Where can check that all gpio/pwm default are right for kernel?
<wens> silviop: the default brightness level is an index into the brightness level array, not a percentage or absolute value
<silviop> ok default is 8 but the backlight switch off
<silviop> 8 means 80 in index
<silviop> now i'm tryng to remoce AXP20X driver from kernel to see if GPIOX is setting wrong
<wens> mainline kernel does not support the GPIO pins for the AXP
<wens> iirc the dts file even has a comment about this
<silviop> ok but not support and initialize AXP20X wrong may be has the same effect on my tablet
<silviop> fedora with kernel old sunxi 3.4 work well
<silviop> 4.4.0-rc5 not
<wens> thats because while gpio are not supported, the regulators on the gpio 0/1 pins are, and they are switched off if not used
<wens> which also either pulls that pin low, or leaves it floating
<wens> either way, your backlight will go dark.
<silviop> so uboot drive axp209 correctly enabling them , and kernel reset AXP209 ?
<wens> for those particular pins, yes
<silviop> make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- sunxi_defconfig by default not select AXP20X under driver->power devices (i'm following official guide)
<wens> it's not that issue. as i said, the axp20x regulator driver supports gpio_ldo[01], which are on gpio[01]
<wens> if these regulators aren't used, they are turned off by the kernel
<silviop> what means "by kernel" ? i'm searching where i2c comunnication with these specific registers is done...
<wens> the regulator core turns off all unused regulator during lateinit
<wens> see drivers/regulator/core.c
<wens> and drivers/regulator/axp20x-regulator.c
<silviop> Ok i will try to recompile without support for AXP20X in any form , so kernel cannot know AXP209 and should left in the state configured by uboot

<GeneralStupid> KotCzarny: just a snippet from dmesg https://dpaste.de/T8Ko
<GeneralStupid> KotCzarny: [ 1828.737010] dvb-usb: This USB2.0 device cannot be run on a USB1.1 port. (it lacks a hardware PID filter)
<KotCzarny> uhum
<KotCzarny> have you tried different device in that port?
<GeneralStupid> yes, it works
<KotCzarny> might be buggy hub if it is a hub
iamfrankenstein has joined #linux-sunxi
<GeneralStupid> no, its directly in the orange pi
<KotCzarny> usb world is very buggy
<GeneralStupid> it is a bit fancy. if i reboot now, the chances are 50/50 that the device works again...
<GeneralStupid> Its just a quick idea but i guess one port is always usb 1.1 and the device rolls dices for that
dev1990 has joined #linux-sunxi
<KotCzarny> is it connected directly into device without the hub?
bonbons has joined #linux-sunxi
philippe_fouquet has quit [Remote host closed the connection]
<GeneralStupid> i dont have a hub on hat device
<GeneralStupid> just three usb ports in that device
<KotCzarny> another idea, insufficient/unstable power?
<GeneralStupid> i already had issues with that, so i switched the cable and measured the current, and it is was stable
<GeneralStupid> KotCzarny: tricky...
<KotCzarny> i have one remote controller that never works when my pc is booted with it connected, but reconnecting fixes it
<KotCzarny> i wonder if sunxi devices can turn usb power on/off
enrico_ has quit [Quit: Bye]
<GeneralStupid> KotCzarny: yes they can :D
<KotCzarny> then its easy to powercycle the device
<GeneralStupid> /sys/bus/usb/devices/.../authorized works
<KotCzarny> no
<GeneralStupid> but it always connects back with 1.1
<KotCzarny> authorized only disconnectd data
<KotCzarny> not actually cuts power on the port
<KotCzarny> i've had usb-hub-control source somewhere that can turn port on/off
<GeneralStupid> oh ok
<GeneralStupid> everything i read in the www is that i have to search in sys/bus/pci... but
orly_owl has joined #linux-sunxi
<GeneralStupid> are there ARM devices with pci bus? :D
<KotCzarny> no, some usb hubs can turn port power on/off
<KotCzarny> its not pci related
<KotCzarny> No power switching (usb 1.0)
<KotCzarny> meh
<KotCzarny> another idea would be cutting power to the usb device (but usb 5v could be directly powered from the system tho)

tlwoerner has joined #linux-sunxi
<Inode> if you do not connect the sunxi USB +5V line to the hub, and the powered hub's regulated +5V supply is reasonably good, is it still dangerous?
<KotCzarny> i've read some post that powered hub leaked power onto the sunxi, and it has no safeguards
<Inode> ah ok, it's a pity more hub's don't have proper isolation

<KotCzarny> it was related to bananas, but i guess other boxes could suffer the same
<Inode> as far as peripherals are concerned: GND is a must, but Vcc could come from anywhere if the level is within 4.75V-5.25V, afaik
<KotCzarny> so, gnd-gnd multimeter + cut 5V on the hub side
<KotCzarny> another funny article i've seen was >100V gnd-gnd from ungrounded tv connection
