T428 Study and Research on Experimental Firmwares

[ginopaneg]

I'm very sorry to say that I was wrong...
I confirm that this nexus rom, it's the best, for now but
I was able to reproduce the video stutter problem, it occurs when the camera move a large portion (entirely) of the screen left to right, up to bottom or viceversa
It's difficult to see because when a small part of the screen is involved there's no problem or it's not visible but when occurs this kind of camera movement the thing is clear

I think that isnt an hardware issue, hoping that new sdk will help

Well , to have a first shot of Ubuntu on your T428 with the wifi working but without the mali support for now.

Download the Ubuntu 12.10 filesystem from this link and put it on your sdcard

http://www.slatedroid.com/topic/41654-pre-alpha-03-ubuntu-linux-for-mk802-iii-ug802-mk808-ug007-imito-mx1/

Download this my file <DELETED>

Flash kernel-recovery.img as normal recovery in your T428

copy the two files from wifi firmware in /lib/firmware folder of your sdcard

copy the file from wifi module in /lib/modules folder of your sdcard.
when you are in Ubuntu load it with the command:
sudo insmod /lib/modules/rkwifi.ko

Insert the sdcard

From Android: reboot recovery



for the graphics part we are working, do not worry.

strauzo,

I follow your instruction and get wifi to work in T428. In addition, I compile modules in T428 for some usb devices using Alok's kernel git repository and .config from Klement (in Rikomagic Forum).

However, I want to boot to Ubuntu in the command line mode. How can I stop xbuntu or xfce to boot? The best is to remove xubuntu. Please advise.

I find that the speed improvement between [email protected] (performance) and [email protected] (ondemand) is only about 10-20%. It is even less if comparing at the same performance mode.

Strauzo, is possible reboot in CWM Recovery mod, y tested ( fast rebeboot.apk), does not work, tanks.

you can reboot in CWM recovery only if you have installed CWM recovery that you can download from the first post.

reflash only the recovery.img that is the CWM

but is not necessary for now. we have made also some experiment to install the rom with CWM and also some some patchs. all are working.

but for many users with this hdmi stiks is more simple with the standard rockchip flash tool reinstalling the system.img when is necessary.

you can read this http://superuser.com/questions/31097...ithout-the-gui

but i think that can't work if we don't enable in the kernel "Console display driver support"

ssh should still work so it would be still usefull as an headless network machine.
but a regular console video out is always a good thing

yes sure ssh work like all other things. you can use also SFTP (ftp over ssh) for file transfer.

in this way, for example, with your desktop pc you can have the full control of your mini ubuntu server, for file transfer and commands.

only the graphical part is slow, if you want see videos or for 3d because there isn't the support of mali gpu.

When setting up the wifi in T428 as an access point, I got these errors after running
sudo service hostapd restart

If anyone knows how to solve it, please advise.

I have the cube rom with sdk 2 full working on T428 with kernel 720p

today i wll share this for video tests for all.

the same rom posted in other thread, not have the kernel of the t428 and not have audio. is only the same without any modification of the cube rom. Infact the the boot.img is kernel +boot but kernel of cube. for this reason it start.

if in the rom that i will share you have again the video jitter, i know where is the problem. precisely

in the late afternoon i will share this cube rom sdk 2 for the T428

[aruangra]

This is a bit unrelated to T428 but it is on the linux for RK3188. I could compile the module 8192cu.ko successfully as I posted here

http://www.rikomagic.co.uk/forum/viewtopic.php?f=13&t=4696&p=14579#p14579

Any advice is appreciated.

Youre a smart guy but sometimes just dont have any common sense! That kernel is from the latest official tronsmart rom (6/16) - it includes working camera fixes. I havent tested it with the the latest cube fw myself so I dont know if it has audio issue with their rom or not but to say it isnt tronsmarts is just wrong, and it also works fine for me with the pipo rom - Ive been using since it was posted last week. Also, no offense, but now you say you know where to fix the jitter and in the beggining of the thread you said there was no jitter and your rom was perfect. Make your mind up! and plz get more feedback with this new rom before you go making grandeous claims and insulting users who dont agree with your findings again With that being said, thanks for saving me the trouble of having to do this myself, im sure your work will def be sufficient!

Heres the link to firmware thread too since I know you missed it:

I say:

test this rom that is the cube sdk2 ported from cube for T428 with all working, and if you see again video jitter problem, i know very well where is the problem.

i say this because because I can not see this problem well.

You do not understand anything of what I wrote. I know I have problems with English, but I was referring to this nonsense here:

http://www.freaktab.com/showthread.php?5490-Good-news-for-soc-RK3188&p=74331&viewfull=1#post74331

the rom posted by you is only the original rom of the cube without any kernel modification, with the original cube kernel. look the size of your boot.img
There is also inside the kernel.img that you speak about, but is not installed and will never work with this rom without the right changes.
you were wrong to create the image, and as a result you install the rom of the cube without any modification, in fact the resolution is 1920x1600 like the standard cube kernel, without audio and without many many things working.

and before you offend make more attention

now, if you want test the rom posted by me, if you see again video jitter, i know exactly where is the video problem.


I have not yet said that in this rom there isn't the problem. if there is a problem, I know where it is and i can explain to all.

This rom still uses the older kernel.img for the t428 without camera support and does not include cwm. I will make modifications and post alternate img for users who want latest and greatest + cwm for rom backup. Thanks for replacing boot.img for me!
