I have the Pine64 LCD touchscreen kit and was wondering if anybody would have the time to help configure it to work with OpenAuto. It looks like this would be a good use for the kit and I might finally get some use out of it. I tried to set everything up with the Armbian image but I couldn't get aasdk compiled properly because I didn't have the correct version of protobuf or something. Any help would be appreciated!

Rock64 4GB poor USB3 HDD performance |
|

I've received my Rock64 4GB a few weeks back but I'm having some trouble getting the external hard drive to perform as it should.
I really hope anyone here has some idea's on how to get performance up to spec because I'm about to pull my hair out with this issue. The main purpose of the Rock64 was a replacement for my RasbPI3 as a NAS. Since the Rock64 has Gigabit ethernet and USB3 it seemed like a good fit but so far it's been dissapointing. (It's rock stable though  )
The drive I'm a Seagate STEA4000400 USB3 (powered by wall adapter) which performs great on my Windows rig. Transferring files from the same server as I'm using to test with the Rock64 gives me a stable 110MB/s up/down.
I'm currently running bionic-minimal-rock64-0.6.31-209-arm64, but I've also tried xenial-minimal-rock64-0.5.15-136-arm64 (the current stable release) and but had similar results.
Right now I'm only get around 20MB/s write and about 40MB/s read on the drive when using RSYNC or SAMBA, which seems way too low.
I've tried Rsync (SSH), then after reading SSH might be the culprit for poor speed changed to NFS, then when this didn't help I tried the Rsync protocol (no notable change in performance). Then said screw it and tried transferring files via samba, same crap performance. I just tried to do a local rysnc moving files around on the drive, around 18MB/s.
At first the drive was formatted as EXT4, I've formatted it to NTFS now and still get the same performance. (I didn't expect any improvement, but this gave me the change to test the drive on my windows machine, which doesn't have the problem).
Here's some more debugging I've tried to do to narrow down the cause.. (all done with governor @ performance on 4.4.120-rockchip-ayufan-209)

Hello everyone!
I've just bought a Rock64 board on 31 March and I received acknowledge from Sales team for this order.
My question is, how long does it usually takes for an order to be shipped after being placed? I haven't found any info about this...
Thank you very much in advance for your time and help, regards...

Hi guys,
I am trying Android (root) on my Rock64, I would like to use it with a gamepad rather then my keyboard+touchpad, the pad is working but I can only do tap/click and nothing more, all the buttons perform the same action, so I can't go back etc...
Does anyone of you have any idea how to make it possible?
Thanks in advance!

Has anyone been able to run the arduino IDE on the rock64?
I tried to on the latest Xenial mainline ... It seemed to install just fine, but doesn't launch.
I just got a couple of different ESP32 dev boards, thought I'd play with them, on the Rock 64

Hello everyone, I recently purchased a rock64 SbC and I want to install arch linux. I've installed u-boot and installed/burned arch linux onto my micro sd card and hdd. Upon booting it for the first time I got no signal on my keyboard and mouse. Then I booted it for the second time and my keyboard flash it's lights, so did the mouse but my monitor DID NOT detect any signal.
Any Ideas?
The image I used is from this one, I've also tried this image. That didn't fix anything.
You might be asking ' why arch linux and not one of the software images in the rock64 wiki? ' - Well Fedora has a problem with the root password. Debian cannot connect to my wifi network, Xenial mate does but it's laggy and sluggish, Xenial I3 doesn't connect to my wifi network. And I have experience with arch linux, I would prefer Void Linux over Arch but the board isn't supported.

I recently noticed a significant increase of overlapping posts/ threads on the forum. Realistically speaking this probably cannot be avoided as new members join to have one or two questions answered so they can set up their hardware. But I do think that it would be beneficial to have this under control.
To this end, I feel that a part of the problem is that people do not us/ do not know how to use the search functions available to them. Typing in a search query in the box on the top right of the forum is rarely useful because of how myBB interprets a search.
For instance, a search for
Quote:Rock64 GPIO
is understood as Rock64 OR GPIO as opposed to the AND behavior most people expect.
To get the search results you'd expect you need to write AND linking the two or more search words, such as in this example:
Quote:Rock64 AND GPIO
But even so the results of the search are hit n' miss. I find that a better alternative for a quick search is using google's search engine. In google type site:forum.pine64.org followed by the search words, e.g.:
![[Image: SUfiuyB.png]](https://i.imgur.com/SUfiuyB.png)
But lets get back to what is available in myBB. If you look above the top black bar with the search box, you'll see a looking glass icon labeled 'Search' which looks like this:
Clicking it reveals a number of useful options including: restricting searches to a sub-forum (device), max/min number of responses, author, username(s), date-range of the thread/post, prefixes, etc,.
![[Image: MFQMrl5.png]](https://i.imgur.com/MFQMrl5.png)
By narrowing your search to the sub-forum (device) and including a few other bits of information that one may remember or expect, its actually quite possible to narrow down the search to just a few threads/ posts that are relevant. In the case of my example, I included the handle of the person working on GPIO, narrowed the search down to the Rock64 sub-forum, and requested search results of all threads where the combination of the criteria appear. Here is the query results:
![[Image: IWG6znm.png]](https://i.imgur.com/IWG6znm.png)
As you can see, when used correctly myBB search can actually be quite useful. Not only does it help you find that you need or join the relevant thread, but it also spares the mods some pointless work of redirecting people to the correct threads.
In short, please use the search function before posting. Thanks.

| Rock64 kernel compilation - configs |
|
Posted by: acrobatbob - 04-06-2018, 02:55 AM - Forum: General Discussion on ROCK64

Hi Community,
The project I am working on requires SCTP protocol support on the Rock64, which I believe is not configured for the current mainline kernel (although perhaps compiled as a module?). I test the SCTP support using the checksctp function from lksctp-tools package.
I have attempted to compile and flash the kernel through the supplied Debian platform, but unfortunately the device no longer boots.
Perhaps I am being a little simplistic in my steps for achieving a custom kernel:
-- edit config (CONFIG_IP_SCTP=y amongst various others required for SCTP)
-- build kernel on-device for ARM64 architecture
-- sudo make install
Is it preferable to build the kernel using the linux-build branch (in conjunction with uboot)?
Thanks

Hey guys after a lengthy search for my first single board I settled on the Rock64 mostly because of the 4gb ram. I wish that it had wifi but a dongle works just as well and gives it a little more character. Anyways I just wanted to say hey and thank you for this board.
It has been many years since I have used linux so I have some reading to do tonight. The wiki seems very informative.  Also I have some future plans to bring many more people into the single board world and I hope that this community will help and welcome them.
I do have one question right now. I flashed my 64gb SD with jessie-minimal-rock64-0.5.15-136-arm64.img however it has no desktop enviroment. What is the easiest way for me to get a pretty looking and easy to use linux up and running quickly? Also security is a major issue. It must be safe.
Thanks,
J
