  HDMI Compatability
Posted by: rahlquist - 07-06-2017, 08:19 AM - Forum: General Discussion on PINE A64(+) - Replies (5)

So, its been a good while. The question is, has anything been done with any of the OS that has increased HDMI compatibility, or is it still shi%t? The main reason I bought the Pine64 was to use it as a playback device with Plex since it touted its 4k compatibility, and since even a Pi can work with nearly all HDMI devices I expected this to work, but every time I have tried only one Tv/Monitor in my house out of 5 works.


  Pinebook browser performance
Posted by: advait - 07-06-2017, 05:35 AM - Forum: General Discussion on Pinebook - Replies (6)

Hi pine community,
For android image
Can anyone tell the reason behind poor performance of chrome (or any other) browser mostly during video playing ( VLC player's output is nice )?
Is there any solution?


  GPIO LED blinker using SYSFS on the Rock64
Posted by: MarkHaysHarris777 - 07-06-2017, 03:41 AM - Forum: General Discussion on ROCK64 - Replies (20)

   

In the above pic I'm blinking an LED at physical pin(16) of the Rock64, GPIO3_A5, on the PI-2 bus;

... to use the sysfs method of setting the pin on|off one must first calculate the gpio# using the following:

( bank_num  * 32 )  + ( pad_name * 8 ) + pad_num

where pad names = {A:0, B:1, C:2, D:3}

In the above example the bank_num is 3 , pad_name is 0*8,  and the pad_num is 5 ,  so:
 ( 3 * 32 ) + ( 0 * 8 ) + 5  =  101

The following steps are used to set the gpio pin on|off:

1) sudo -i
2) echo 101 > /sys/class/gpio/export
3) echo out > /sys/class/gpio/gpio101/direction
4) echo 1 > /sys/class/gpio/gpio101/value          <--ON
5) echo 0 > /sys/class/gpio/gpio101/value          <--OFF

The following codes will blink gpio101 at pin(16), GPIO3_A5:  blinker.sh and sysled.sh are closely related scripts. The former is a controlled loop, and the latter is a forever running loop;  both are useful. Compare the two script and notice that they are almost identical.

blinker.sh

Code:
#!/bin/sh

echo $1 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio$1/direction

COUNTER=0
while [ $COUNTER -lt $2 ]; do
   echo 1 > /sys/class/gpio/gpio$1/value
   sleep .35
   echo 0 > /sys/class/gpio/gpio$1/value
   sleep .65
   COUNTER=$(($COUNTER+1))
done

echo $1 > /sys/class/gpio/unexport

To run blinker enter two parameters;  the first the gpio#, and the second the number of times you want it to blink!

sudo  ./blinker.sh  101  7

(will blink gpio101 seven times)


sysled.sh

Code:
#!/bin/sh

echo $1  > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio$1/direction

COUNTER=0
while [ $COUNTER -lt 10 ]; do
   echo 1 > /sys/class/gpio/gpio$1/value
   sleep .35
   echo 0 > /sys/class/gpio/gpio$1/value
   sleep .65
done


To run sysled: 

sudo  -b  ./sysled.sh  101

(will strobe gpio101 forever)

( remember to cd into the working directory where you place the script   )
( also, don't forget to make the script executable: chmod 0754 sysled.sh )

   

In the pic above I have attached the grey wire at ground pin(14),  and the orange wire at pin(16).

The anode of the LED is attached at the orange wire, and the cathode of the LED is attached to the grey wire through the ballast resistor , which is 330 ohms. The LED is a low power (5-7ma) 3mm standard LED.

I have so far tested the blue pins ( see chart ) and the green pins.  DO NOT use the blue pins if you're using the micro SD card !  If you're booting from the eMMC module (as I am) then the blue pins and most of the green pins are available to you;


  Throttling?
Posted by: genosensor - 07-05-2017, 10:12 PM - Forum: Rock64 Hardware and Accessories - Replies (8)

I'm looking at this board as an upgrade to my Hardkernel C2.
Even with its large heatsink, the C2 reaches 72C under load, in my experience.
(but it does not throttle!)

The Rock 64 has similar power dissipation in the same form factor.
Can anyone recommend case and/or heat sink for it that will keep it from throttling under sustained load?

Thanks!


Question Building up to LXDE from Xenial-Minimal
Posted by: falcon15500 - 07-05-2017, 06:11 PM - Forum: Linux on Pinebook - Replies (2)

Hi all,

As per the thread heading, I am in the process of building up LXDE from the Xenial-Minimal 0.6.1 image.

Let me tell you - so far it's been quite a trial! Smile
I am very close to having things running how I would like them, with a few exceptions that irk me.

At the present time I cannot get suspend working when I close the PB lid.
In journalctl I can see the following:

Jul 06 00:08:23 pinebook kernel: hall: (D) hall_isr
Jul 06 00:08:23 pinebook kernel: hall: (I) HALL_CLOSE
Jul 06 00:08:27 pinebook kernel: hall: (D) hall_isr
Jul 06 00:08:27 pinebook kernel: hall: (I) HALL_OPEN

So obviously the kernel is detecting the lid position changes.
How can I get the suspend working off this?  I currently have xfce-power-manager running (for a battery applet) and although it is set to suspend on lid close - it doesn't.

Anyone have any ideas?  

M.


  Does the ROCK64 support CEC over HDMI?
Posted by: mpb - 07-05-2017, 02:00 PM - Forum: Linux on Rock64 - Replies (2)

Hello,

Does the ROCK64 support CEC (Consumer Electronics Control) over HDMI?  CEC allows the SBC to turn a connected HDTV on (and off) over HDMI, change the HDTV's input, and possibly control other functions.

I believe the Raspberry Pi has CEC support.  While I have never used CEC on a Raspberry Pi, I do have some project ideas in mind.

More info here:

Thanks!


  Issues booting remixOS image
Posted by: remi - 07-05-2017, 11:57 AM - Forum: Android on Pinebook - Replies (2)

Hi, 
I have sucessfully booted android 7.1 from an external sdcard (after decrompressing the 16gb sdcard boot image using etcher), just by inserting the SDcard in the reader port and powering up the laptop, without even removing the internal eMMC which contains ubuntu MATE that came from the factory.

However I cannot get the remixOS image, decompressed to the same SD card using etcher, to boot. Upon powering up the laptop, the power led just blinks forever and nothing happens. I have tried to activate the special boot mode by pressing the power button repeatedly right after powerup with no success.

Is there anything I am missing ?

Regards


Music Problems using Spotify Web version because DRM (Firefox & Chromium)
Posted by: Ekkaia - 07-05-2017, 11:07 AM - Forum: Linux on Pinebook - Replies (6)

Hello.

I'm trying to use Spotify Web version, http://play.spotify.com.
I tried on Chromium and Firefox, but both cases I'd been redirected to a Spotify message saying (for me in spanish, try to write on english): "The play of DRM content is not enabled" and a link to a how-to for both navigators:
https://support.spotify.com/es/using_spo...eb-player/

I have the configuration in Chromium that says the article, but still getting the same message.
In Firefox there are no option like said in the article.

Anyone knows how to use Spotify Web? (cause no ARM .deb version from the application)

Thanks.


Smile Ubuntu Release Upgrade (16.04 => 16.10 => 17.04) working
Posted by: stohn - 07-05-2017, 09:03 AM - Forum: Linux on Pinebook - Replies (19)

I just played around with the ubuntu release upgrade which does not want to start due to insufficient space in "/boot" reported (asking for 40MB more).

Out of curiosity I booted from SD card and increased the boot partition of the integrated eMMC with "gparted" (shrink ext4 partition by 50 MB and move to right, expand boot partition by 50 MB).

Later I was able to do a release upgrade of ubuntu using the standard commands.

It took quite a while. But 2 hours and one reboot later I had Ubuntu 16.10 running on my pinebook.
The kernel itself was NOT updated (/boot stayed 100% same). 

No problems so far with Ubuntu 16.10 and the old 3.10 kernel. All seems to work as expected.

So increasing the /boot partition by 40 MB seems to do the trick (even that it is not used).


Will try 17.04 upgrade next.

Just did another upgrade to 17.04. It took much longer to upgrade but it is also running ok.
