Yeah finally got it delivered with my 32GB eMMC and PSU.

Like the PSU supplied seems quite a thick and substantial power lead.
32GB eMMC seemed to come with partitions and already set up.
Not sure what image was on it but it wasn't a Rock64 image.

So got my oDroid eMMC->SD adaptor and bunged it in the computer for etcher to burn the Xenial mate image just for tests as quick and easy test.

And here I am as a proud new owner of a rock64.

So off to buy some new bits for my exploration of Rockland.

First impressions seem much faster than the Pi3, pretty glad already had a heatsink like the one that will end up in the store, its nice and warm and doing its job.

Preface



This quick and simple guide will show how to create a NFS Share using your Rock64. NFS has a few advantages over SMB, if you know your network well and will use it with linux clients. Apart from marginally faster file transfers, NFS allows you to retain Unix File permissions. 



Prerequisites


ROCK64 board running Debian or Ubuntu, connected to the local network

Access to terminal, either locally or via SSH

Some basic understanding of using the linux terminal: Howtogeek

Suggested: A basic comprehension of linux file permissions

I have one lying around.

If I only contribute one thing to the rock64 project, I think this should be a good one.  

Looking around at instructions and documentation to write an image to the eMMC, I have not come across this yet and it's blowing my mind.  

eMMC to microUSB adapter ($1.50):
http://www.hardkernel.com/main/products/...5415955758

I have an oDroid XU4 with an eMMC module, and this is the adapter I've been using to write an image to it (via dd on OSX).  Done the same with my ROCK64, and I think this is something everyone should own if they play with SBC's with eMMC, and I think PINE needs to source these and add them to the store.  In my limited testing, worked like a charm with ayufan's Debian Stretch Minimal image (just straight up used dd to write to the eMMC on my hackintosh, and booted straight to it).

Enjoy.

Hi, I'm not an expert when it comes to computers, and I'm completely new to SBC's. What I want to know is if there's any way to split/expand the number of USB ports on the Rock64. I see the wired, USB keyboard for the Rock64 in the Pine store advertises that it has two additional USB ports (although it would add only one net port, obviously), so I figure if the keyboard can contain two additional ports, then it must be possible to add a USB port or two to the Rock64 without having to tether it a full-sized, wired keyboard. I don't want to add that kind of bulk, but if I add the Bluetooth keyboard, the WiFi, the IR remote, etc. I'm worried I'll have too few USB ports.
Any recommendations?

Hi all,

just got my new ROCK 64 4GB in today, along with 2 PoE adapters and a 64GB eMMC module.  Was all excited so to first test I put Debian Stretch on a 16GB microSD card, inserted the card, connected the PoE adapter to my ROCK64 (ethernet, then the 3.5mm barrel jack), and then connected the PoE adapter to an ethernet cable connected to my Dell X1026P PoE switch (802.3af compliant, possibly 802.3at compliant...not sure).  I get a yellow light on the PoE adapter (I assume the yellow light is link connectivity) then it fades out.  About every 60 seconds (assuming I leave it connected), it comes back on then goes off.  I never get any lights on the ROCK64 board itself.  Nothing, nada.  Try the second PoE adapter I have (both ordered from the Pine store), and it does the exact same thing.

So I've got a oDroid XU4 running that has a 5V/4A adapter with a 5.5mm barrel jack.  I have a few 5.5mm to 3.5mm adapters, so I try one of those with this PSU connecting to the ROCK64 (with the microSD card inserted), and nothing.  Unplug, remove the microSD, plug it back to the PSU.  Nothing.  Swap the 5.5mm to 3.5mm adapter with another, and nothing.

I've tried several things, but am not seeing any LED's on the board light up.  Ugh.  I've mashed the power, reset, and recovery buttons hoping to do something, but still nothing.

I'm guessing my board is DoA?  Anything else I can try?  Have there been reports of DoA boards or do I just have crappy luck?  Totally not looking forward to waiting another 2 weeks to play with one of these, assuming I have to have a replacement sent.  Come on, surely there is something else I can try?

Hi
Have anybody got any usb gps dongles to work with android on Pine64+? I would love to have positioning to work on my Pine64 with touchscreen. If anybody have tried it and got it to work, it would be nice to know

anyone have success with the dongle listed above?

Am I missing any step(s)?

running ubuntu 16.04 with linux-rock64 v 0.5.13

Hi,I'm now trouble in eMMC.
That is strange freespace shortage on eMMC. 
I use 32GB eMMC on Rock64 xenial mate.
First,Rock64 was boot from Micro SD(xenial mate).
And used dd command to write xenial mate image to eMMC.
Write image and boot from eMMC is suceccful.
I used this command fdisk /dev/mmcblk0 and delete mmcblk0p7,create new primary pertition,rewrite this.
After that,I use apt-get update,and install any software using apt-get install ~.
but install was unsucces because freespace shortage.
I'm searching reasons, and I noticed contradiction.
that is this picture.
There are difference of partition mmcblk0p7 size in df command and fdisk command.
I thought to expand partition mmcblk0p7 was success.
But I see screen of df command, mmcblk0p7 was not expand?

I tried another eMMC card and not occuerd problem.
So I doubt initial failure.
I want to help if you know about this issue.


Thank you and sorry my bad english.

I have installed Xorg*, lightdm, and xfce4

The only log I can find is lightdm's, and the pertinant errors seems to be:
failed to launch plymouth

and

Can't launch X server X not found in path

Whats next?

Thanks all

Cheers, Gene
