Hi,
I am using Ubuntu LXDE on Rockpro64.
Any library that can be used with this image to access GPIO?
Also how can i control fan.
Thanks.

Hi ,

Does this board support 4k LCD (Sony Xperia Z5 Premium) thro MIPI-DSI? 

If yes, what are components I need other than the LCD& the board?

Thank  you.

For the life of me, I cannot find the location described in the wiki for the antenna locations. It says:

Quote: In the back section of the case at the very top you will find three cut-outs where the SMA antennas can be fitted.

I have a raspberry pi respeaker hat I want to use on the rock64, but their install scripts only work on the raspberry pi. It looks like most of the script is easily modified to work on the rock64, but I'm not sure about the DTB file.  I decompiled it and it's over my head.  What is needed to make this compatible with the rock64?

This is the decompiled overlay file:

Hello,
I've had a problem with the write speeds I'm getting over wired connection, I'm only getting about 2-4 MBps at best, when I expect at least 60.
I'v installed auyfan's stretch-openmediavault-rockpro64-0.7.10-1072-armhf, the device is connected to a gigabit router, also tested connecting it directly to my machine with similar results.
I'm suspecting it had something to do with the Realtek RTL8211 driver not installed correctly, 

Hi everyone,

I'm trying to read GPIO output and using Rock64's RPi module is too slow as it is using file system.
Does anyone know memory addresses of those pins? I'd like to map directly and hopefully it will be faster.

Alyssa have been working like mad on Panfrost Open Source driver..
They used a RK3399 ARM laptop...

They were able to run some wayland applications, and performance checks on glmark2-es2

This drivers adds support for:

Midgard (Mali Txxx)
Bifrost (Mali Gxx)

Is there any reason you can't install an OS (Debian please) on the MMC and keep the SD for data that you might want to plug into another machine?  Don't know if they're both mapped to the same address or something.  Maybe it's been answered before.

I would expect to do a dmesg when booted from the MMC and see a new device had been attached then be able to mount the partition(s) on it manually.  (Oh, that's right, it isn't kosher to hotplug an SD card, but like a USB stick or drive or SD in a USB reader.)  Or maybe boot from the SD as an alternative to what's on the MMC.  I've never had an MMC.

First of all this is my first sbc and I might not doing somethings properly.tas fan from pine store, 16GB eMMC in NAS Metal Case.
I used "LXDE Desktop aarch64 [microSD / eMMC Boot] [0.7.9]" 


1) How do you control the fan?
2) Is there any HW Acceleration? Youtube, daily motion are playing with 20-25 fps top. 
I played with some kernels but didn't see any difference (only in sound, the known bug). 

3) WiFi module doesn't work. Is this normal? I saw something in changelog. I also upgrade to 0.7.10 by changing apt lists and didn't see any difference.
4) Can't get the SATA PCIe work in graphic environment.
If I press ctrl+alt+f1 and login, I can see the PCIe card (lspci works), I can use parted, format the drive and mount it succesfully.
If I try to use LXDE everything freezes.
If I don't do anything with the drive, even lspci freezes the rpro64. 
So my HDD is useless in desktop mode.

Is anyone experience the same problems?
Is there any Linux distribution that works without problems? Any kernel suggestion?

Hi,

I've posted this in another thread:

It used to show up before but then totally disappear. The HDD spins up but does not show up in lsblk or in dmesg. There's no LED burning on the card. The HDD works aswell.

Doing a dmesg | grep pci gives me this:

Code:

Okay so I installed mainline and I get a similar error:

Code:

But it happens a lot less consistently, mostly reboots and a bit of reseating of the cables makes it function again.
