Hi everybody,
This thread is about getting Linux running on the UG802, and later, various other Rockchip RK3066 devices (TV sticks and tablets).
A Spanish company named BQ recently released a copy of the RK3066 Android kernel source for their Edison tablet.
I started working on it a couple of weeks ago and I am happy to report that I have a very preliminary version of the Linux kernel booting on my UG802 (since 5am this morning).
This is a very early version and I don't have HDMI output (~~there is a small bug in the hdmi kernel driver and I am investigating it~~ I found the problem, actually what happens is the HDMI is right now configured as the secondary display - this kernel was originally for a tablet and the primary display is an LCD screen), and also the WiFi is not working (that's easier to solve: I just have to compile the Realtek driver separately from the kernel). I have managed to get adb working and the kernel boots without locking up.
So there we go, in a week or so I should hopefully have Ubuntu Linux 12.10 (Quantal) running on the UG802.
The nice thing about it is the speed: this little thing is fast!

Here is an extract from dmesg output:

Waiting in anticipation. Do you know if it will be able to run at 1080p? I know the mk802 had some issues regarding HD content.

Hi,
Too early to say anything, but the datasheet for the RK3066 says it supports 1080p.

Yet another quick update: I got Ubuntu Quantal booting in text mode (no X window support) without network, and various smaller issues. But... it's booting!

Thanks Andrew,

I am sure many people are awaiting the first beta for testing. Will we be able to see the full 1.6GHz as the RK3066 Tablets run at that speed or is it not possible?

Keep up the good work.

Does it have a bluetooth module onboard or did it pick up a plug n play version?

Check the dmesg "Bogomips", it's actually already booting at 1.6GHz. So yes, it's possible, the kernel code supports it.

EDIT: I was wrong on that one, the lpj value is hardcoded in the kernel so that the Bogomips value is always reported as 16xx.xx Bogomips on boot. Checking the kernel code, right now the UG802 is booting at 1.5 GHz but by uncommenting some code it could run as high as 1.6 GHz which seems to be the top speed for the RK3066.

And another quick update: I am now booting the UG802 into XFCE Ubuntu Quantal in 720p mode. Still no networking though, no sound, and quite a few issues with this kernel still... :huh:

Anyways, I'll post a screen shot in a few minutes (I have to save the screenshot on the microSD card, shutdown the UG802, remove the microSD card, plug it into the adapter and then plug it into my Linux box, and finally upload it to the web from my Linux box - all this because I still have no network on the UG802).

Wow this is super. I think a lot are looking to run Linux on the UG802. I just want to run it as a fast low power home server. So I don't need the video. It could just be text video. Would need the network. I have a USB to Ethernet that works on it now.

I been looking on the web about one time a week for "ug802 Ubnutu" That's how I found this. Looks like you all most got it working.

Would it be easy to make a Ubuntu server for this? I guess if you get the network working it my be all set. But I guess you mean the Wireless in it right? I could just use the USB to Ethernet. Maybe that would work with what you have now.

I have the HDMI display sorted out, it is now working in full HD. However, I am still having issues with the USB port, any high speed peripheral (Bluetooth, Wifi dongle, etc) plugged in seems to have problems, and I have no idea what is happening, still have to gather more data. :huh:

The USB to Ethernet Adapter is a Cisco Linksys model: USB300M it works real good with the UG802 OS that comes with it. I hope Ubuntu will work with it too.

It will be so very good for you to be done with Ubuntu. I hope you can all so make Ubuntu server work with it. I would love that. Because it would be so good to have a 24/7 very low power fast home Ubuntu server.

I don't get why they don't sell it like that.

From the benchmarks I have run on the UG802, it seems the CPU is powerful enough to be used as a nice home server running Linux. However, the specific format of the UG802 (PC stick with only one usable USB port) is not really the best for this application. It would be much better if somebody could come up with a small server enclosure with two 2.5" hard disk bays, and a Gigabit Ethernet port plus a few USB ports.

Right now for over a year I been running a home server with a Tonidoplug2 it works good but on things it is slow. That's why I am looking for somthing faster. This Tonidoplug2 is a ARM 800 MHz and only 512 of RAM. It has a SATA port and I have two 3TB WD green hard drives on it. The boot with the Sata port and a Sata cord. The other a USB one. It has USB 3.0 n the hard drive but not on the Tonidoplug.

For years it looks like there were going to come out with a 2 GHz Tonidoplug3 but never did. On Google images can look for "Marvell Plug Computer 3.0" and the red one is it. But look at how old some of them post are.

If can get the UG802 to run Ubuntu server I could just put my two 3TB hard drive on it's USB port with a USB hub.

I guess if they gave it so you could buy the UG802 with Ubuntu installed on it. A lot more would buy it.

Just a quick update: I am finally managing to get the wifi interface going on the UG802! Well, sort of: when I load the driver module the Wifi interface appears (wlan0) and the chip is partly initialized... but it's still not usable.
Hopefully I'll manage to debug this today.

EDIT: WiFi working with a Realtek USB dongle that uses a slightly different chipset.

Hi AndrewDB,

First of all, thank you very much for your work, its amazing. Im a linux user waiting for my UG802, it could be fantastic for me install Ubuntu or Debian instead of Android. I can help you when i received my device.

What about Mali400 hardware acceleration? have you tried some video without it?

Mali is a GPU (Graphics Processing Unit) which is used for 2D and 3D graphics acceleration (OpenGL ES).

Apart from having 4 Mali cores (clocked at 266MHz on the UG802), the RK3066 also has a very capable VPU (Video Processing Unit) for hardware decoding of various video formats.

For Mali acceleration under Linux, there are various projects under way, the source code is available and with some development work, it can be made to work on the RK3066. I would say between 3 and 6 months for a single developer, but that could be cut down to a couple of months if many people join in.

For Video acceleration under Linux, there is a kernel driver source available for the RK2918 and the code should be quite similar for the RK3066, but that remains to be checked. Depending again on how many people join in the development effort, and various other factors, that could also be made to work in a couple of months. And of course if Rockchip would release some source code and documentation, it could turn into a matter of weeks.
