  Sata/PCI-E problems?
Posted by: Takenover83 - 09-26-2018, 05:16 PM - Forum: Linux on RockPro64 - Replies (6)

I am currently running Ubuntu 18.04 Bionic minimal 0.7.9, with a custom 4.18.9 kernel. Although I have tried others kernels as well. My board is in the NAS enclosure with the 30mm heatsink and a 80mm fan (5-amp power supply). I am running it as a server for Plex, Radarr, Sonarr, Jackett, Deluge, Ombi, and Tautulli. 

I am currently experiencing a strange problem with the sata drive, a Western Digital 8TB Red Drive. Or perhaps the problem is with the pci-e card, not sure. I often have quiet a few torrents downloading via deluge.  Usually about once or twice a day, I come back to see all of my torrents have error'ed out. Likely, because the drive is somewhat disconnected? Doing a df -h shows it is still mounted, but the drive will not function properly until I do a complete power down. Just curious if anyone else has experienced any troubles similar to this. Either way I am documenting the problem here just in case someone else experiences the problem in the future and can chime in.


  Gentoo, Current state, Test Phase
Posted by: khaosgrille - 09-26-2018, 05:11 AM - Forum: Linux on RockPro64 - Replies (12)

Hi,
I changed the title to avoid confusion since i decided to fork ayufan's buildscript. Currently it is very promising but I need to fix a few issues before I  make it forum post about it.
Here is a link to my todo list for the script https://gitlab.com/khaosgrille/linux-bui...aster/ToDo and ofc the script itself https://gitlab.com/khaosgrille/linux-build
The goal of the script is to crosscompile an Image with I3Wm and some basic packages.
It will use one script where you can look over all stuff i preinstall so you can change it and get your own Image. Currently there is not much missing for an headless system (see my ToDo file).


I deleted the text of my old post here and changed the title since the method I used first did boot but didn't gave me a nice way  for modding and testing. I will do a fresh new release thread when all is in a more presentable state.
Sorry for the inconvience and the silence for a month. presentable

Quote:Hi,

quick update from me. I had few problems with scripting the last steps. I have given up (quite early honestly) and  done them by hand  and here is an image (https://grmr.de/khaosgrille/gentoo3.img.tar.xz)

I  only made a minimal image without X or any tweaks. If u use a sd card as a medium I strongly recommend using TMPDIR on tmpfs.
SD Cards have not enough space/inodes and compiling several packages in a row is nearly impossible.
(https://wiki.gentoo.org/wiki/Portage_TMPDIR_on_tmpfs)

If everything works fine I will make a bigger announcement in the forum. I would like feedback and hear about things you would like to add.

The /boot dir is currently not quite working in the script (but in the image). Sadly I will be to busy to finish the script.   I just copied the /boot and the /boot/efi/ from ayufans ubuntu^^.

Greetings
Khaosgrille

PS: The image is for 16gb SD cards and is with DHCPCD aswell as the arm/17.0/Desktop profile.

  What do i use the pinebook for?
Posted by: icemeister - 09-25-2018, 04:37 PM - Forum: General Discussion on Pinebook - Replies (14)

i have yet to find a good reason to own the pinebook. i had high hope when i first got it but now not so much. I keep setting it aside for awhile then keep coming back to computer and getting frustrated i keep getting an error about internal 16.04 failed, unable to get software, unable to install vpn, touch pad works to well, no upgrade to 18.4 ubuntu, unable to format flash drive,etc.

what i like is battery life, used on plane to watch movies worked ok, lightweight, good looking, easy to load operating system.
As a newbie i would like to use to help me learn more about linux so i do not have to go to win 10 but as an old guy i just am  not getting it.
looks like most of the attention is going to the rock64 and the pinebook is just being set aside or is it.
Thanks for the forum to vent

  NVMe and new kernel
Posted by: bjbb17 - 09-25-2018, 03:39 PM - Forum: Linux on Pine A64(+) - No Replies

Hi,

Ive got my rockpro64 up and running basically following the procedure of flashing the ubuntu image to Emmc and from there , move / to an NVMe (Samsung 960Pro), which works great,

just .. how to get to a new Ayufan kernel up and running. Tried pretty much what I can (incl extlinux, manual dd's, flags, flash-kernel, tinkering in /boot, etc.) to the extent where it still loads .132-10975 kernel, whatsoever (even though all is installed for  .138-1094)

Before going any deeper, anybody know this issue ?

A simple snippet on how the boot procedure actually works on the rockpro64 eMMC case would probably help as well.

 Thanks a lot,

 Bjoern


  Help with linux task schuduler at 4.18, please
Posted by: dukla2000 - 09-25-2018, 02:10 PM - Forum: Linux on RockPro64 - Replies (3)

Hi all

Is there anyone here who understands how to "tune" the Linux task scheduler? My problem is that at 4.18.9 it does not obviously favour the big cores for CPU heavy jobs which is crazy.

I wrote a little script to demonstrate what I mean - it uses an additional package stress as an example that can spawn n jobs for t seconds. In my case I run the load for 10 seconds, and after 5 seconds have a look which CPUs are in use:

Code:
stress -c 1 -t 10 &
sleep 5
ps -L -o pid,lwp,pcpu,cpuid,time
sleep 6
stress -c 2 -t 10 &
sleep 5
ps -L -o pid,lwp,pcpu,cpuid,time
sleep 6
stress -c 3 -t 10 &
sleep 5
ps -o pid,lwp,pcpu,cpuid,time
sleep 6
stress -c 4 -t 10 &
sleep 5
ps -L -o pid,lwp,pcpu,cpuid,time

On the 4.4.138 (Ayufan) kernel things are pretty much to be expected - CPUs 4 & 5 (the big A72 cores) are always used:
Code:
$ ./testcpu
stress: info: [1043] dispatching hogs: 1 cpu, 0 io, 0 vm, 0 hdd
  PID   LWP %CPU CPUID     TIME
  741   741  0.0     4 00:00:00

 1074  1074  0.0     0 00:00:00
stress: info: [1067] successful run completed in 10s

On 4.18.9 (despite all my efforts configuring the kernel) it is more luck whether CPUs 4 or 5 do any work:

Code:

There does seem to be a kernel CONFIG option at 4.4, ARM_ROCKCHIP_CPUFREQ, that could explain the 4.4 behaviour. And is not available at 4.18.9. But in reality I would expect stock/mainline 4.18 scheduling to cope properly with big.LITTLE CPUs?

Any thoughts/suggestions welcomed.


  Upcoming Shipments?
Posted by: jschall - 09-25-2018, 01:59 PM - Forum: General Discussion on Pinebook - Replies (5)

I received my BTO coupon for my 11" Pinebook about 2 weeks ago, and it mentioned that if I ordered then it would ship around the end of October. I ordered the same day.

I sent an email to inquire when my Pinebook would be shipped, but so far I haven't heard from Pine64.

Is it possible to get an update on the production and shipping status of all the recent Pinebook orders?

  Camera interface with rockpro64
Posted by: rahulsharma - 09-24-2018, 11:19 PM - Forum: General Discussion on ROCKPRO64 - Replies (4)

Hi,
I am just about to buy Rockpro64 board. I am going to use Linux image on that. With that i want to have some camera applications such as Orbslam.
Please confirm which best camera should i use with Rockpro64. As i found few cameras which are either given to be supported with the Pin64+ level boards or with Android stock.
Thanks.


  Need Kernel Headers for 3.10 kernel
Posted by: ravikant@redpinesignals.com - 09-24-2018, 10:38 PM - Forum: General Discussion on PINE A64-LTS / SOPINE - Replies (1)

Hi,
I am trying to compile a driver for Xubuntu Mate running on PIne64 A+ board. I need to get kernel headers for compiling the driver. Can you please point me to the link or command to download the related headers. I have tried normal commands we use on ubuntu/fedora systems for downloading headers, but it doesn't so anything. Please suggest

Currently running OS has kernel v3.10.104. Is there a way to upgrade the kernel version, link to v3.18 or higher.

Thanks in advance
