Yes this is very exciting! Clever chaps :D

This will benefit all RK3066 devices and allow the same Linux functionality as the MK802II but with much more horsepower!

Hi everybody,
I am the developer of Ubuntu Linux on the RK3066. I was contacted by Andy Kirby and he is kindly sending me a sample of the MK 802 III for development work. I expect to have an Alpha version of Ubuntu Linux 12.10 Quantal running on it in a few days and I'll publish a dual boot Android / Ubuntu Linux ROM as soon as possible (yes it's possible to dual boot Android and Linux on the RK3066).
Andy also sent me the kernel source for the RK3066. I had previously been working on a leaked version of the RK3066 kernel source (the "Edison" kernel) that was based on earlier code from Rockchip.

Based on my work on the kernel, I can already explain some of the issues users have encountered with the RK3066 devices:

Some TVs not supported / blank screen: this is due to poor coding of the EDID detection code in the HDMI driver in the RK3066 kernel. As soon as possible I am going to work on this.

1080p not fully supported / screen stretching issues: this is due to incorrect memory allocation and incorrect scaling parameters in the HDMI code. This I have already solved. The RK3066 is perfectly capable of full HD resolution (1080p) for normal Android/Linux use and movie playback.

Wifi issues (apart from antenna issues): the RTL8188 chip used in the MK802 III has many different options that can be set when the driver is loaded at runtime and these affect the stability of the wifi connections and the speed. There is work to be done to find the perfect combination of parameters.

Heat vs. max speed issues: the RK3066 has both clock and voltage scaling capabilities and the kernel has various cpufreq governors available, each one with parameters that can be changed to obtain the best results i.e. the best compromise between speed and heat. Again here some work is required but the code is there.

Excellent news. I'm looking forward to following your work. I have a question you might be able to answer. I've been looking for a way to change the boot splash image in the kernel. Is the kernel source named rk30board? I'm trying to find the source so I could compile a new splash image into it.

Can you give me an idea if I'm on the right path to getting this done?

The kernel only has an option to display a Linux penguin at boot (actually two penguins since this is a dual core processor), what you are really trying to modify is the Android boot splash screen. This has nothing to do with the kernel. Just Google for "Android boot splash" and you'll find plenty of links explaining how to do it.

ARM Cortex A9 Dual Core 1.0Ghz is faster than the Intel Atom N450 Dual Core 1.0GHz.

If he can, imagine the ARM A9: http://www.youtube.com/watch?v=UIBGg6CFE0U
Great job AndrewDB! :D

AndrewDB - Boot Splash search results all point to the same solution: convert a png to rle and replace the RLE in the ROM. But for the life of me I can't find any RLE files on this device. I've searched with RootExplorer, looked through the firmware upgrade downloaded from here, unpacked the BootImage in the firmware and looked through that. Am I missing something?

I don't mean to take you away from the more important work your doing for this device but was hoping if you happen to know what I'm missing you might be able to tell me off the top of your head. Thanks again.

hi AndrewDB

would you consider to devlop a dual boot Rom for the NEO G4 ?

btw, great job ! pls keep up !
