  Rock64 Desktop OS for...
Posted by: AkiraSensei - 02-12-2018, 02:40 PM - Forum: General Discussion on ROCK64 - Replies (4)

Well, I've spent hours through the forum but I can't seem to find posts that would help with my setup. I hope someone can help me by making this thread.

I ordered a Rock64 that may arrive today or tomorrow. Problem is that I still don't know what OS to install! Here are my needs:

1. Needs the desktop. I want to be able to browse the internet on it through VNC. For minor, periodic browsing throught the day.

2. I want it to be able to run Kodi (through HDMI) and play HVEC videos at 1080p. I don't want OpenElec since I can't web browse on that.

3. I despise Android. Please, no Android recommendation.

I am able to do this on a Raspberry Pi 3 but the hardware is so limited and it can't play HVEC videos at all.

I see Debian on the OS list but they're all stretch versions (that means they're beta, right?). Do they take advantage of Mali so I could play said video types I've just mentioned? Should I go for Ayufan's version? What about Xenial Mate?

Who uses a Rock64 for similar purposes? Much appreciated for any input!


  Differences between Android and Android TV images
Posted by: 1n9i9c7om - 02-12-2018, 02:21 PM - Forum: Android on Rock64 - Replies (8)

Hi, 

I've just received my Rock64 and I'm planning to use Kodi and other multimedia apps on it, while it's connected to my TV. 

Should i be using the Android 7.1.2 or the Android TV 7.1.2 image? What's the difference between the two? 

Thanks!


  advice requested for purchase
Posted by: Ikke - 02-12-2018, 01:51 PM - Forum: Getting Started - Replies (5)

Hello everyone, 

Since I'm totally new to single board computers I have read a lot on the internet, but still have some questions.  Based on the specs, the Pine SBC seems the most interesting to me.  However I've read several posts about long and/or difficult shippings and on top of that the official website informs the potential buyers the shipping time is somewhere between 3 and 9 weeks or even longer.  Therefore I'm worried about this. 

At this point I'm hesitating between purchasing an 'old' Pine A64+ at a local reseller just around the corner or purchasing the 'new' Pine 64 - LTS through the webstore.  This brings me to the question I would like to ask to the forum members: Is it worth waiting an undefined time to get the 'new' LTS-version or should the 'old' A64+ be good enough to be used as simple file server ?  (only a few and small files between max 10 PC's)

Thanks in advance for your replies. 

Kind regards. 

PS: Sorry for my English. I'm dutch.


  Cannot control volume with amixer command
Posted by: user_rock - 02-12-2018, 12:22 PM - Forum: Linux on Rock64 - Replies (3)

Hi everyone,

I am using Rock64 and trying to play mp3 files on headphone jack. The playback part is working fine. I having trouble with controlling the volume with amixer command. When I try amixer sset Master 100 it shows me error "Cannot find simple control 'Master',0"

The reason behind the use of amixer is I have ported this application from raspberry pi and I need to keep it consistent on either device. I am using Debian stretch minimal image.
Exact version:

Code:
Linux rock64 4.4.77-rockchip-ayufan-136 #1 SMP Thu Oct 12 09:14:48 UTC 2017 aarch64 GNU/Linux


Also, amixer scontrols command does not return anything.

Kindly help.

Thanks!


  Bluetooth Pairing Problems
Posted by: Flecktarnfarbe - 02-12-2018, 12:18 PM - Forum: Debian - Replies (2)

Hey Guys,

I have some problems to pair my BT keyboard.
I am using Debian Jessie with Mate DE [3.10.102 BSP 2] by Lenny Raposo.
My keyboard is a Rapoo e6700. BT is the on Board modul.
My problem is, I can pair the device but a second later it is disconnected.
The keyboard works fine with other devices like iPad oder Galaxy Tab 10.1.

Can someone help me?

Thanks Sebastian


  u-boot on SPI: USB boot partition
Posted by: prof7bit - 02-12-2018, 10:20 AM - Forum: General Discussion on ROCK64 - Replies (1)

I have read that it is possible to flash u-boot to the SPI flash to have more choice on boot devices. I have also seen a tutorial in the wiki mentioning it. But what I could not find is a detailed description of what is actually going on when u-boot is starting:

* does it look for a certain device type or are all USB mass storage or UBS/SATA bridges supported?
* does it look for a certain position in the USB bus, for example always the first USB storage found anywhere or always only the first port on the first hub?
* does it search all devices and look for a partition with a certain label?

I cannot seem to find any documentation about this u-boot configuration, also generally I cannot find much documentation about the boot process of the Rock64,  for example if the SPI flash is erased, what does it look for if it comes out of reset, is there always a fixed minimal loader in mask ROM somewhere and is it documented? Is it possible to accidentally brick the device?

It would be nice if someone could give a detailed description of the boot process, please describe it as detailed and low level as possible, target audience for this description would be an embedded (cortex M0 and M4) bare metal programmer who has no fear of beginnig to learn about the low level stuff going on during initialization and boot  in the larger ARM processors.

Thank you.


  Lakka poor performance experience
Posted by: Danielsan - 02-11-2018, 06:24 PM - Forum: General Discussion on ROCK64 - Replies (2)

Hi guys,

The performance with Rock64 and Lakka aren't good enough to have a good experience out of the box, I got a better experience with a PI2 and Retropie.
Probably Lakka needs a better tuning so I would like to understand where is the place to get help to solve these issues, I mean here or on the Libretro forum.

Thanks in advance,

Daniel

  snapd
Posted by: c1derly - 02-11-2018, 01:48 PM - Forum: Linux on Rock64 - Replies (4)

I am trying to install NextCloud on my rock64 but i'm running into a problem.  NextCloud uses snapd to install its packages which is supposed to come with ubuntu 16.04 by default.  It does not appear to be installed on the rock64 xenial image version 0.5.15-136.  I tried installing it manually but it failed because it failed to mount the core.  The error was: "mount[31508]: mount: unknown filesystem type 'squashfs'".  I tried to do an internet search and it mentioned this can be an issue with custom linux kernals.  I wasn't able to find anything more helpful then that though in how to fix the issue.  Does anyone have any suggestions on how to fix this issue?  Also in case the forum manager sees this i might have made this thread on the wrong board earlier for the pine64.  If it did go through please remove it.
