Hi,

From the reference manual "Rockchip RK3399 TRM V1.3 Part2", Table 7-6 shows the MIPI DPHY PLL Settings for 27 MHz reference Clock. However, the default clock is 24 MHz (pll_refclk) for the RK3399.

How is the table generated for 24 MHz?

Thanks.

Hi,

I have a rockpro64 with 4Gb and I am running Linux aarch64
I was trying DSI Non-burst mode in rockpro64 with the pine64 display, but display was not coming properly. This setup was working properly in DSI burst mode.
I have a question, Does High-speed data transfer occurs only in DSI burst mode?

Thanks.

Hello, All.

I am attempting to use a Rockpro64 with bionic-minimal-rockpro64-0.7.9-1067-arm64.img as a headless server.

When initially powered on, everything works as expected, but after an amount of time that seems to vary between six hours and two days, the Rockpro64 stops responding to ssh, pings, and web requests. I tried connecting a monitor and keyboard to troubleshoot the problem. From the Rockpro64, the following things are true:

1. I can successfully ping other computers on the network by IP address, but pinging domains fails.
2. I can ssh into localhost, but cannot ssh into any other servers, even by referencing their IP addresses.
3. "arp" runs extremely slowly, but "arp -n" completes near-instantaneously.
4. Restarting the Rockpro64 fixes the problem temporarily, until it inevitably  comes back.

It looks like a DNS issue to me, but I do not know where to look from there. Do any of you wonderful people have suggestions?

My inexperience with Linux is the main problem. I'm used to solving my own technical problems, especially now that we have the Internet! With Linux, though, I keep running into walls that I have trouble overcoming.

I suspect, though, that some of my frustrations in installing wifi dongles on an A64+ may be due to bugs with software, whether Longsleep's image or other software I've installed.

Here are my steps, and the results. I'll mention installing VNC because that was a step I took. I'm still hopeful that I can get that going, but I'm open to all suggestions: 

1. Balena Etcher flash of xubuntu-xenial-mate-20161215-longsleep-pine64-8GB.img.gz onto 64gb micro SD (since I ran out of room with previous attempt using 32GB) -- Result great!

2. Sudo resize_rootfs.sh

3. Sudo apt-get update a couple times. Plus sudo apt-get upgrade and sudo apt autoremove a couple times.

4. Sudo apt-get install vnc4server -- Result: never did get it working as I have on Rasp Pi 3B+

5. Sudo apt-get install nano build-essential linux-headers-generic git

6. Mkdir ~/RTL8188EU

7. cd to above

8. git clone git://github.com/lwfinger/rtl8188eu
Result:
434 objects enumerated
434 of 434 objects counted
310 of 310 objects compressed
received 100% (12615/12615)
resolved deltas 100% (9368/9368)
connectivity checked

9. cd to ~/RTL8188EU/rtl8188eu

10. make all
Result: 
make ARCH=arm64 CROSS_COMPILE= -C /lib/modules/3.10.104/build M=/home/ubun/RTL8188EU/rtl8188eu  modules
make[1]: *** /lib/modules/3.10.104/build: No such file or directory.  Stop.
Makefile:151: recipe for target 'modules' failed
make: *** [modules] Error 2


11. Tried make instead of make all. Same result.

12. Looked in /lib/modules/ to confirm that there's a 3.10.104 folder.

13. Looked in /lib/modules/3.10.104 folder to find shortcut called "build". So it's /lib/modules/3.10.104/build. Looked at properties. The target is: /home/hxwong/build-pine64-image/linux-pine64
This will fail, right? If anything tries to build/make, whatever, it'll look for hxwong instead of ubun or whatever you have.

What did I miss? What should I do (or not have done)?

Early Kickstarter of Pine A64+

Are there any specific requirements on the POE side for the Rock64 rev3?

I had this board humming along for a good long while, and forgot about it for awhile.  Now whenever I apply power, I get a quick red LED blink once a second, with no other feedback.

The board is stenciled:

A64-DB-2G-Rev B
2016-02-25

I've searched and not found any report of a red LED blinking on boot, only solid red LED.

Can anyone tell me if it's a board failure, corrupted microSD, failed PSU, anything else?

Your experience and help is very much appreciated!

Hi
I'm using the Pine A64+ (will update shortly to the LTS) for a project at work. 
I need to use several I2C sensors and SPI sensors too. 
Also, found the library for one of the sensors for RPi and I was wondering... the same tutorials/codes/examples/libraries from RPi work on the Pine A64?? 
I'm using Armbian Stretch, since I'm familiar with Debian

Thanks for the help

I ordered a 64GB eMMC for my Rock64.

The eMMC arrived preformatted in exFAT, and contained ransomware.
