Is the PI-2 bus compatible with the Raspberry Pi GPIO connector with respect to IO levels for the UART, e.g. will a FTDI Friend! from AdaFruit work on the ROCKPRO64?

Is the serial console configured on UART2_DBG when using this Linux image: https://github.com/ayufan-rock64/linux-b...m64.img.xz  ?

My Rock64 is currently running:

Ubuntu 16.04.5 LTS (GNU/Linux 4.4.132-1075-rockchip-ayufan-ga83beded8524 aarch64)

I see that Ubuntu 18.04.1 is ready for upgrade but when I started the upgrade I was cautioned about doing this via SSH. Since my use is exclusively Samba & FTP, is there a really good reason to upgrade at this time? I probably should have gone with a simple Debian build in the first place but I have little interest in starting over.

What is the likelihood that the distro upgrade via SSH will crash? How stable is 18.04 LTS?

Any thoughts will be greatly appreciated.

Best,
Tom

Hi,
I'm trying to use my Rock64 board to automate astronomical observations, I mainly use an ASI camera (https://astronomy-imaging-camera.com/pro...m-pro-mono) and a filter wheel.
The camera is USB3, and provides its own USB2 hub to attach other peripheals (like the filter wheel). The camera USB hub can be externally powered (and it currently is), so current shouldn't be an issue.

I tried different configurations for the ubuntu images (both armbian and ayufan):
 - 18.04 32bit: worked pretty fine at some point, but with some instabilities here and there while shooting. The latest installation though seems to fail pretty much consistently after circa 17 shots, I'm seeing lots of these messages on my kernel log:

Someone has build kernel 4.18.8

What is the current supported MACHINE target for the ROCKPRO64? My PCB is version 2.1

Which Yocto branch should be used? pyro?

Thanks!

Hello all,

Recently my office picked up several Rock64 boards to be used for a network monitoring wall project. We have two network walls, the first consists of 3 50" televisions and the second consists of 4 55" televisions. I noticed that when using very long HDMI cables, in our case 50 ft, the hdmi signal is too weak and the TV displays no signal.

Is there a config_hdmi_boost value that I can modify like on the Raspberry Pi? 

I know that the best case scenario is to mount the board to the back of the television and use a short cable. Our network wall already had four 50 ft and three 25 ft HDMI cables run in the ceiling of our office.

Thanks,

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?

So recently installed lxde and when playing video be in kodi, omx or youtube video plays faster. How do I make it play at regular speed?

        I notice in the following link that https://www.itead.cc/blog/how-to-use-nex...spberry-pi Raberry Pi has GND, 5V TX and RX so does
Rock64 According to the Schematic http://opensource.rock-chips.com/images/...170309.pdf Rock64 also has
UART1, UART2 TX and RX along with 5V and GND. Which Pin Should I be using ?  Its going to be Pin 8 for TX & Pin 10 for RX or is it going to be Pine Or is it going to be Pin 19 for TX and Pine 21 for RX ?? 
I have attached the image

Is there another department?

I have 2 orders.

I want to place 30 more.

Humble thanks
