Which GPIO pins on the rockpro64 feature hardware PWM?


  Fitting Rockpro64 inside Pinebook case
Posted by: made2hack - 02-19-2019, 11:37 AM - Forum: Rock64 Hardware and Accessories - Replies (2)

Hi all,

Please note that I've not delved into the matter properly (ie read the specs or look at the sizes) yet. But, conceivably, do you think at first glance it might be possible to fit the Rockpro64 Board inside the bottom case of the Pinebook? 14" model.

Thanks and regards,


  Read CPU info (temperature, clock speed)
Posted by: Borglesnorgle Williams - 02-19-2019, 09:18 AM - Forum: Ubuntu - Replies (1)

Is there a way to read housekeeping information about the CPU (current clock speed, number of cores active, temperature)? I'm running longsleep Xenial 3.10.105 kernel.


  Unable to Run GNOME or KDE due to "dmidecode" segmentation fault
Posted by: rrs64 - 02-19-2019, 03:50 AM - Forum: General Discussion on ROCKPRO64 - Replies (4)

Hi All:

I've installed the following CentOS 7 image onto an SD card which successfully boots the RockPro64 with 4 Gb RAM and eMMC card:

    Centos-7.4.1708 with kernel from Armbian-5.67.img.xz

It was downloaded directly from the Project31 GitHub web page:

    https://project31.github.io/pine64/

After first boot the /root/finish-centos-install.sh script was run to complete setup.

Then GNOME was installed with the following command which completes successfully:
    

Code:
# yum -y groups install "GNOME Desktop"
Next, attempt to launch GNOME using the command:
Code:
# startx

It fails to launch due to a segmentation fault from "dmidecode" shown below:

The same segmentation fault occurs at the command line if "dmidecode" is run by itself.

Re-booting, 'yum update'. or starting over with a new SD card does not help.

Has anyone else had the same problem trying to install and run GNOME (or KDE) on CentOS on RockPro64?

This issue is a real blocker trying to get a graphical interface up and running.

Any hints or suggestions are welcome.

Thanks


  GPIO in sleep mode
Posted by: Mentaluproar - 02-18-2019, 03:27 AM - Forum: RockPro64 Hardware and Accessories - Replies (2)

I want to do a fade in and out of an LED while the board is in sleep mode.  I can easily do this in arduino, but would rather have the rockpro64 do it.  Is there anything the rockpro64 can do while asleep aside from wait for a signal to wake it up?


  Storage in Android
Posted by: kevin - 02-18-2019, 01:27 AM - Forum: Android on Rock64 - Replies (1)

What should I do replace the storage from internal storage to SD card

My android phone can not give me the way, how to replace it

When I download a thing, the notification directly appears that your memory storage is full. Actually, I have plugged in my SD card

So, how to manage, what should I do


  Hello and some general advice.
Posted by: vinylash - 02-17-2019, 10:58 AM - Forum: General Discussion on PINE A64(+) - Replies (2)

Hi guy's. I'm new to the forum. I'm an sbc enthusiast and currently own a raspberry pi 0,2,3 and 3b+ as well as an odroid XU4Q. But I've turned my attention to a pine A64 (512mb) variant, which I've been able to pick up for a really good price. 
 
Before it turns up in the post I have some general questions:
1. What would be the recommended Linux OS for this board? I know it's the lowest hardware version so after something lightweight but usable for light DE tasks and possibly packages to set up a Nas. What have other users found a good set up? 
2. I've read a few threads in regards to these boards being picky about being powered through micro usb and a workaround by powering through the EULA bus. Could I chop the end off one of my 5v2amp pi adapters and connect to the DC in pins? 
3. What micro SD cards are guys using on their boards? Any perticular brands that work well? 
4. And finally, what sort of heat does the SoC give off? Will I potentially need to apply a heatsink? My pi 3 makes some mega heat when under load. 

Any other advice or things to watch out for would be greatly appreciated. Thanks in advance?

Ash
