T-R42 custom firmware by wasser

[wasser]

Hello wasser,

Thank you, again.
I tried it out... but unfortunately it seems not to work (at least I don't get it to work).

1. try :
I overrided your previous kernel.
The result was a very low resolution.
(I'm not able to see the available screen settings,
maybe there is the resolution within the settings
but I can't see the settings at all. )

2. try :
After a factory reset and reinstallation of Lewys 2.0.4,
and your 1366 kernel it just flickers.

In the meantime I wasn't lazy and tried to solve it by myself.
I patched and compiled the kernel from sawolf...

It works with my patched kernel, but I miss all the other nice stuff and bugfixes from your kernel.
I suppose you have the things not githubbed.

During the researches I figured out that the resolution is a problem child,
because there is no official EDID code for it. So I had overwritten the 720x480 resolution. :-(
But that wouln't matters If you or somebody else would provide an alternative Lapdock kernel version.

And again... I offers you a beer...
Or in the improbably case you don't like beer a coffee or something else.
Oh jesus... after 3am already... I need some rest...

Thank you very much !

Hi Gery,

there's an minor difference between my and your fix. In my fix i added the 1366x768p resolution instead overwriting. I found a typo in my fix, perhaps it could be a cause. I uploaded new kernel. Could you please test again?

thanks

Wasser

Hello Wasser,

Can You PM me a link to the Complete Firmware Images You are using on the K-r42...

I will reload My system with your firmware and Make sure I have the same stuff as You do for my testing ...

I was thinking about my earily post and Network load time ...
I am sorry I have been testing with your 1080p kernel and I normally use your 720p
Kernel ... Could You post you latest kernel for me to test in 720p ....for k-r42

Thanks Wasser...

Michael T.

3) i cannot reproduce this problem on my box. It's strange!
4) i already reverted it in this kernel

[wasser]

Hi Wasser, great work, thanks for you contribution to the community, as well as thanks to michael2t for helping me with some noob problems.

I was wondering if there was a mod or something that could make the rom boot up and not have the controls at the bottom of the screen?

you can get rid of panel at the bottom of the screen, just install the full!screen app and enable it

games

Hi,

flashed my T-R42 with 1.2 fw,
everything ok (wifi,lan,bt,excellent system speed) but some games not working.
(Shadowrun,Dead Trigger 2,Dungeon Keeper) Games started,but the play/start button is unclickable.
Is there any solution?
Other games working perfectly.
Thanks!

Go get

Tincore Keymapper

From Google Play store ... and Remap keys for game ...

Good Luck

This is a general firmware issue. I am still stuck with stock on mine and Dead Trigger 2 behaves like you describe

Hello wasser,

unfortunately it doesn't work.
I get a non flickering but low resolution gui, after wiping
and installing your kernel.
No chance to start an app, because it is outside the display.
(Here is my next research task, to get a command line without gui... blinded, quasi)
If I wipe and start with another kernel to setup ssh
and then changes to your new kernel,
I get flickering and I can just fire up the following command
over ssh.
am display-size 1366x768
I see that something changes, but the f**king flickering didn't disappear.
No idea what else I can do.
I think the edid parse process selects a to low resolution
and I try to get a commandline, maybe with a serial cable...
or have you an advise for me ?

Thank you.

could you please login over ssh and type following to get HDMI modes.

cat /sys/class/display/display0.HDMI/modes

do you see any resolution 1366x768-p60?

if yes please try: echo 1366x768-60 > /sys/class/display/display0.HDMI/mode

thanks

Can You describe the sequence of actions??? ROM_Flash_Tool_137 shows path \FinlessROM\*.img
which is not there + filelist does not correspond to files in the folder IMAGE...
Thank You!

Thank You!

1 start ROM_Flash_Tool_137
2 just click on entries in dialog to choose the img from correct path (the imges are in Images directory)

Ok, and which difference in kernel.img, kernel-720.img, kernel-1080.img ??? kernel.img is it stock??

Hi Wasser ,Let us try your firmware, it's interesting how it works "sleep" and usb
P.s i have k-r42 with board v2.1

Hello again...

here is the list of steps I've done...
1. wiped and reflashed lewy 2.0.4
2. sshd setup and res. to 720x480
(this resolution setting prevented the flickering after kernel flash,
but no chance to get rid of the small resolution. http://gerrytec.de/beforewiped)
3. flashed your kernel
4. fired up following command.

root@android:/ # cat /sys/class/display/display0.HDMI/modes
[B]720x576p-50
720x480p-60[/B]

While I researched things for the patch I found something.

https://www.miniand.com/forums/forums/picuntu-linux/topics/how-to-change-the-resolution

I guess the monitor just transmit 2 matching edid codes.
That was the reason why I had overwitten code 2 with the 1366 resolution.
Next step I will try to extract all edid modes from the monitor.

http://askubuntu.com/questions/81370/how-to-create-extract-the-edid-for-from-a-monitor

Maybe the monitor sends a code for 1366 and we can add it to the availabale modes.
Here is a list of edid codes, but the 1366 is not listed

http://en.wikipedia.org/wiki/Extended_display_identification_data

Otherwise i suppose there are only 2 solutions left:
1. overwrite the unuseful 720x480 as in my patch (edid code 2).
2. patch hdmi_edid_parse_base() in hdmi-core.c to show all modes.

I can checkout the things with my kernel source...
So this is my turn now...
This week I'm very busy but I will commit the results as soon as I can.

Thank you !
