Gentlemen, after which overclocks the device, you can see after the results of the differences are minimal in points

Awaiting the arrival of China MK809III for testing
.gif "Bacon Dance")
Hello Sam. MK809III bought and am waiting to arrive. I am eager to do testing on this device. Thank you for sharing this work. I've made several changes in my MK808 1.6 GHz and the most I could get was 11800 points in Antutu. Now surely doing the overclocking MK809III to 1.9 Ghz will get better score in Antutu. So what do tests on the forum post here for everyone.
Hugs coming from Brazil.

For some reason I can't figure, antutu won't complete benchmarking, it stops half way through saying
it occurred an unexpected error, already uninstalled it and installed it again, but the problem remains... Power supply, aditional cooling, rom, kernel, they're all the same as before when it scored 19177, only the case is different, I do nottice a slight temperature increase on the cpu, but weather temperature has also increased a lot this past week 38°C = 100.4°F. Due to the size and material the case is made of (the previous case was smaller and mostly made of aluminum), might add an heatsink or two more, smaller, fans than the one I'm currently using to see if the problem is solved.
When performing benchmarks I use SetCpu, set both minimum and maximum frequencies to 1920 and choose performance governor, which worked very good untill now, I have no idea what scheduler is best so I keep it on cfq. Sam321, do you advice the use of SetCpu or similar app, or after flashing one of your extreme overclocked kernels they're already set for best performance / stability and there's no need to change anything else? ThanksComment

I do not use any app to set the min or max cpu speed, I use a modified interactive governor so that it is less conservative, however the kernels that I have released here are unmodified, in my opinion these are too conservative as the cpu frequency is set to go to 816mhz only when it reaches 99% which I think is a bit stupid. My stick is only 100% stable running at 1872mhz I have tested this by leaving a game of gta vc running for two days non stop and also xbmc with a video looping for 24 hours with the cpu set at 1872mhz any faster and the app would eventually quitComment

Added two more fans, problem remains, I think I'm going to reflash the rom and kernel, and not use SetCpu, to see if I can get antutu working again. Not that I have any complains, system performance is great as it is, but I want to try to figure what's causing the problem. Is there any working CWM for the mk802iv / rk3188 you know of? I can't get this one (http://androtab.info/clockworkmod/rockchip/rk3188/) to workComment

what do you need CWM to 3188 I am using the 3066MY MINI PC: C4,CS918,M8,M8CComment

I just flashed recovery.img from this archive http://files.androtab.info/rockchip/...ENERIC_CWM.zip with RKAndroidTool (recovery.img only!). It worked for me (Cozyswan S400)Originally posted by BrunoNRG View PostComment

Hallo sam321. I'd like to try to play around with kernels in order to get a USB webcam running. Could you point to a some good description how to build a kernel from sources.
Whats what i get:
Code:$:~/src/Linux3188$ make ARCH=arm CROSS_COMPILE=$CCOMPILER /home/me/arm-eabi-4.6/bin/arm-eabi-gcc: 1: /home/me/arm-eabi-4.6/bin/arm-eabi-gcc: Syntax error: "(" unexpected CHK include/linux/version.h CHK include/generated/utsrelease.h make[1]: `include/generated/mach-types.h' is up to date.

First open a terminal and type
sudo apt-get install gcc-arm-linux-gnueabihf build-essential git uboot-mkimage libncurses5-dev
then modify make_kernel_ruikemei.sh in a text editor the make line so it looks like this
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- kernel.img -j4
save it and then run make_kernel_ruikemei.shComment

Thank you! It almost worked.Originally posted by sam321 View Post
Make requieres ../initramfs/initramfs.cpio to exists. I tried one from https://plus.google.com/109451178006...ts/UBA47ksJpix, so i could build a kernel.img but i get stuck in ramfs boot console. It seems not to be the right one for booting to Android. Could you please share the initramfs.cpio you use, as well as voltages table for overclocking (arch/arm/mach-rk3188/board-rk3188-box.c ?)

Thank You, sam321!Originally posted by sam321 View Post
I'm still strugling with building a boooting kernel. I use you initramfs.cpio and almost not-modified .config from the repository.
The kernel boots up to some point and than falls into initramfs shell.
I compared dmesg output of your and my kernels and what found.
1. Your kernel don't have any suffix in version (.config from repository implies rk31)
2. I get gcc-4.6 (ubuntu 12.04), you seems to use gcc-4.7.2, I don't really know if it matters. I'll upgrade my installation to 13.04.
3. My kernel is almost 10 MB, yours is ca 8 MB, do you use another compression?
4. The boot stops after USB RF keyboard dongle gets recognized (no error so far) and before rk29xxnand gets initialized. I wonder if that staff is de-configured in the repository.
Could You post your .config ?Comment

I have just looked at the source code on github and it as been altered so that it boots linux instead of android. It is not my account so I do not have any control over it try the source from here https://github.com/omegamoon/Linux3188 .The config should be the same as mine in this one. really I should set up my own github account but then really my alterations are not really important to bother withComment
