  SD card slot failing?
Posted by: gaggleoxfoggy - 09-17-2018, 09:47 AM - Forum: General Discussion on ROCK64 - Replies (2)

I've been working on a Rock64 with Armbian Stretch Desktop 5.42 and at some point it stopped booting into the GUI. I didn't think anything I did should have stopped that, but it's a light build just needing to run some Python so rather than troubleshoot I just flashed a new image. Start getting that running and at some point it does the same thing. After a couple times and trying different SD cards, here's what I am doing:

Flash Armbian image
Do initial boot, create user, get to desktop, join wifi network
Reboot (either from gui or ssh)
After it comes back up, reboot again.
If it comes back up, reboot again.

The first time I reboot, I generally won't be able to connect to wifi again. The next time I reboot, maybe it won't boot, maybe it will and wifi will connect. Generally by the third reboot attempt, I have to just completely pull the power before it will come on again. I've also started seeing a message about my SD card speed being slow, which these are two different SD cards that have been working fine up until a couple days ago when this started.

It seems like there is an issue reading the SD card, and that this issue gets worse as if the card is getting messed up with more use. Is it time to see about getting a replacement board?

  HDMI, EDID and several other questions
Posted by: Aeronaut - 09-15-2018, 05:55 AM - Forum: Linux on Rock64 - No Replies

Hello,
since my Odroid-XU4 died, I think about switching to ROCK64.

From my experience with the XU4 I have several questions related to the GPU hardware acceleration features of the ROCK64, since I want to run some kind of Debian distribution I think that this is the right Forum to ask. (Move / Correct me if this is more related to a General Discussion on ROCK64)


Is ROCK64's able to:

  • run RetroPi, EmulationStation or Retroarch, specially how does mupen64plus perform?
  • run Kodi with ALSA or Pulseaudio with working SPDIF-Passthrough?
  • use an external USB3 Harddrive as UAS and get SAMBA performance around 80 MiB/sec?
  • force the HDMI as always connected with a custom EDID binary?
  • are there also mali-x11, mali-fbdev, kodi, kodi-fbdev packages available or how is it managed?
  • how you compile Kodi/Retroarch, any forks or patches needed?
To the EDID thing:
My Beamer is not detected if in Standby-Mode, but I need to run Kodi with Beamers EDID data...
On the XU4 I got it managed by copying EDID data from sysfs while Beamer was switched on and detected on HDMI the following way:
(See https://forum.odroid.com/viewtopic.php?f=93&t=29488 )


Code:
$ cat /sys/class/drm/card0/card0-HDMI-A-1/edid > /lib/firmware/edid/ax200e.bin

and in the u-boot's ini (/media/boot/boot.ini):


Code:
videoconfig=drm_kms_helper.edid_firmware=edid/ax200e.bin HPD=false //forces HDMI as connected. 


  How to get UHD 4k working (with Android TV 7)
Posted by: Hotkey - 09-15-2018, 04:46 AM - Forum: General Discussion on ROCK64 - Replies (7)

Hi together, 

i received my Rock64 2G yesterday and managed to install android TV on the device without problems. 
After i connected it to my TV (capable of 3840 x 2160 resolution) i hoped to be able to use this resolution, but android settings shows only 1920 x 1080 and no solution above this is selectable.
How can i get 4K Resolution to work with android tv?

The main target is to use the Rock64 as a Kodi Streaming Client for my TV connected to a TVHeadend/Movie Server. If there's a better solution for this than Android as the OS im also open for alternatives
I apppreciate any help; thanks in advance!


  Rockpro64 Ubuntu 18.04 minimal 64 bit - shutdown command
Posted by: whitehat - 09-14-2018, 09:07 PM - Forum: Linux on RockPro64 - Replies (2)

Unless the power supply is unplugged, the system reboots after "shutdown -h now". I just came to find out the system was powered on after a shutdown command last night. I tried the same command again. The problem is reproducible.

Edited. Following comment added: Well, on extra try to reproduce, the problem did not occur. Guess this is intermittent.


  Temps/pwm Survey
Posted by: tuxd3v - 09-14-2018, 05:37 PM - Forum: Linux on RockPro64 - Replies (9)

Hello Guys,

I would like to know, to compare, what temps are you observing, when at full load, 'Ondemand' Governor and  little.big - 1.4 . 1.8 Ghz?

can you Run :

Code:
cat cpufreq-info|grep "current CPU" cat /sys/class/thermal/thermal_zone{0,1}/temp cat /sys/class/hwmon/hwmon0/pwm1

Is your heatsink trembling a lot, under full load?

Thanks in Advance, to all.

Regards


  4.X Kernel?
Posted by: Corkonian - 09-14-2018, 05:30 AM - Forum: Linux on Pinebook - Replies (1)

Is there work in progress for a more modern 4.X Kernel for the Pine64? Maybe even for the Pinebook or did everyone move to the Rockchips?
If there is a development happening how can one support that?


  Setup Pine64+ with OP-TEE
Posted by: stdys - 09-13-2018, 03:23 PM - Forum: Pine A64 Projects, Ideas and Tutorials - No Replies

Hi,

I'm looking for explanations on how to setup a trusted OS in parallel with a normal world OS on the PINE64+, I've already checked the instructions present on the OP-TEE but there are no clear explanation of what steps should be followed and how the file should be put in the micro SD. I would like to know if anyone has already succeeded to setup OP-TEE (and ARM Trusted Firmware) on this board ?
