Απ: [ROM] W30HD - drx v0.01

Obviously ics doesnt like jb 4.2.1 is too new for it. I will replace back the mali drivers and repost rom. Thanks for the logcat.

Thank you very much demetris_l,

I think we can´t insert the modules into the kernel if not share the same "version magic" 3.0.15-svn124 ($ (VERSION). $ (Patchlevel). $ (SUBLEVEL) $ (extraversion)) of our kernel. This may be the problem so that the kernel will not boot

Greetings.
[Miscellaneous Android Development] Demetris:
I found out that Ramos might used -03 optimization compiler and that may caused this:

https://bugs.launchpad.net/igloocommunity/+bug/954783

Maybe replacing some libs will make it work.

I will try that and then i will replace back the old GPU driver if it still doesn't boot.

Hello everyone. I bought a Ramos W30HD just yesterday.

I really appreciate your work, but i have a question.

Is it possible have a CM10 (or 10.1) porting on w30hd? I'm not able to do that, but here there are many developers...So, can anyone help me?

Thanks you

Ps: i will try drx rom once i get the tablet in my ands :D

New ROM still in tests. Can you describe all changes?
[Miscellaneous Android Development] Demetris:
Updated:

- Wireless wifi firmware

- OMX library Decoders and Encoders

- All Proprietary firmwares were replaced with 2013 ones.

I need you to test h/w acceleration with MX player.

When tablet is power off and charging do you see a charge animation?

Wifi ok?
[Miscellaneous Android Development] lazik:

WiFi works ok.no problems at all.

Mx player with hw can't open any video files. Different then on stock that plays videos but with black screen.

New boot animation :laugh:

---------- Post added at 07:05 PM ---------- Previous post was at 06:49 PM ----------

Tablet is off, Charger plugged in. Animation runs about 15secs then disappears. I believe it is still charging?

Ran H/W test with MX player also. No go. Got logcat here. https://docs.google.com/file/d/0B5aYqOneVsTYWklqWFJ2Rzdyc28/edit?usp=sharing

Thanks in advance for your great work guys!
[Miscellaneous Android Development] Demetris:
Thats a normal behaviour.So charging animation works? You sure you didn't have one before? I ask to be sure.
[Miscellaneous Android Development] jnyfox:
Re: [ROM] W30HD - drx v0.01

Animation works for 15secs then it disappears.

Had it also before but it stayed on.

Why?

You changed it somehow?

You added the cyanogenmod boot screen?

Do you know if this firmware related.

Charging the tablet to full. Unplugging, using it on battery power. Battery consumes normally during use. I put the tablet to sleep and leave it that way over the night. In the morning it does not wake up from sleep. Have to put it tp charger again. It shows empty battery status. Battery monitor does not show anything dropping graph. It just show its go down from ie. 74% to 0%. It used to show graph for few days gradually draining the battery(normal operation).

I think this might have come after the drx first rom. So the ramos stock did not have this problem. I am not 100% sure. It might come up just before flashed to drx rom.

Now I have your "enjoy the ride" rom.

I saw somebody writing the same problem. Ramos-tablet comment section I reckon.

Thanks again for great work guys! Keep it up! :beer:
[Miscellaneous Android Development] Demetris:
Blame the chinese battery suppliers not the rom :angel:
[Miscellaneous Android Development] jnyfox:
Re: [ROM] W30HD - drx v0.01

Okay :/

But where does it discharge it? It does not heat up which could occur if something consumes battery quickly. I just was thinking if the problem could be something like os. removing battery stats.

Well guess I crack it open and wire it to multimeter...

I could try to solder an antenna to the gps?
[Miscellaneous Android Development] friedrich420:

[Miscellaneous Android Development] JF-GINO:
Has it ever occurred to anyone here to test the governors?

I ask because no matter what load I put on this thing I cant get core 1,2 & 3 working .... their status is DEACTIVATED.

Only core0 is active on all governors scaling from 200-1400mhz... WTF?

Someone PLEASE also try to confirm that only 1 core is active....

Further, the Video framerate is LOCKED at 42FPS...... and this should not be regardless of missing HW acceleration...

The screen itself is capable of 120 fields or 60hz but the refresh rate is locked at 42.3hz?? ..again, WTF?

Also, my tablet suffers from death when entering deep sleep and I fixed it by changing the sampling rate to 45000 and

raised the min frequency to 300mhz ...

and... this thing lags like a Mother F@c$er!!!! My 7" Elocity Tegra 2 performs better. I had to keep this on performance

just to smooth out the lag on games.

BTW This is the case with both stock and DRX rom...

The battery is not as bad as I expected tho, it lasts me on average 8 hours of mild use and 2% drain on standby every hour.

Ramos really made a bloody mess of this .....

I don't think JB will fix this mess unless the Kernel is optimized for this hardware with the proper drivers and values....

This might also be the reason why they will not release any sources...?

Is there any way of getting an ICS Galaxy Note2 kernel and infusing this tablets applicable drivers to its base??? (which still wont fix H/W video tho)
[Miscellaneous Android Development] Demetris:
Απ: [ROM] W30HD - drx v0.01

You are right, Ramos really messed up this tablet to the point of stupitity. Even for Yamaha audio driver they used Wolfson one I wonder how they made it work :confused: I just find it hard to believe themselves don't have the source code. Only thinking about it makes me laugh. :D

Due to not having the device i would ask anyone with linux and knowledge to run this script on w30hd and w30, upload and sent link with correct device name.

Archive is 7zip so you must extract first to adb binary folder.
[Miscellaneous Android Development] gyrus1:
At least when I play 1080p mkv in MX Player I can see all 4 cores almost fully loaded using "CPU Stats". Otherwise core 1 is running at 1.4GHz and core 2 is sometimes showing activity. I have 0 knowledge about governors and no other multicore cpu tablet so I can not judge about whether it is OK or not.

I thnk if screen refresh rate is ~40fps everything else trying to produce more fps is going to have troubles. I've tried playing a 60fps mkv and roughly it went at 2/3 of normal speed. May be some players other then MX will have a way around it...

Yeah, one may only guess why would not Ramos choose to release sources and sell 10 times more of these devices. Could there be an agreement between samsung and ramos? I guess Ramos must have gotten sources from Samsung at one point. But... you never know.

demetris_I, thank you for your efforts. Sorry I could not be of any help with practical things.

On some other forums discussing w30hd people are saying that device has the same screen as "Acer Iconia Tab A700", namely B101UAN02.1 (picture was included). Do not know if it helps.

[Miscellaneous Android Development] jnyfox:
Re: [ROM] W30HD - drx v0.01

Darevix and demetris_I could you guys take a look on audio drivers?

Theres obviously something wrong. Speaker output is okay i guess, but plugging in earphones(handsfree mic plugs) the problem start. When no audio is sound you can hear quite loud distortion sound. When something plays ie. click sound on touching the screen the distortion ends until it starts again when the click sound ends. When playing a video sound is bad from earphones, muffled and somehow not very clear. I noticed that when i press the answer button down from the cord, audio gets a lot better. More stereo and clearer sound.

I know you told that it has propably a yamaha chip but is a wolfson driver?

Thanks in advance.

Maybe those newer drivers you tried to implement to the previous rom could work now?

[Miscellaneous Android Development] darevix:
Hi, I've posted version 0.02 of the rom. Contains the kernel 3.0.15-svn328. But I would like to ask a question.

To extract the kernel, ramdisk and recovery I am currently using:

dd bs=512 seek=1063 count=10000 if=/dev/block/mmcblk0 of=/scard/tmp-kernel

dd bs=512 seek=33831 count=10000 if=/dev/block/mmcblk0 of=/scard/ tmp-ramdisk.img.ub

dd bs=512 seek=99367 count=10000 if=/dev/block/mmcblk0 of=/scard/tmp-kernel2

dd bs=512 seek=132135 count=10000 if=/dev/block/mmcblk0 of=/scard/tmp-ramdisk-recovery.img.ub

Then with a hex editor I extract the kernel, ramdisk and recovery. It is a simple, but it takes me a long time.

So I'd like to ask if you know any better method to extract these files.

Hi All,

installed the rom, works great so far. Seen some lagging with 1080 mkv-file, but only at the start of the file, after few secondy everything went smooth. Otherwise - we will see. This annoying buzz sound (headset) on the main screen is not gone. The mic from the headset is working though (tried with google playstore).

BTW, hopefully battery consuption drops, as this device is otherwise severely hampered. I have it for less than 24 Hours and recharged it twice already.

[Miscellaneous Android Development] jnyfox:
Re: [ROM] W30HD - drx v0.02

Well 24hours with two charging time sounds like pretty great. If its on heavy use.

Had this with me last night at work. Battery lasted the whole night and it was not even fully charged!

IMO, battery consumption is very low. Battery life is very long. Like I want it :)

No menu

Hello,

Trying to test your new rom following what you said:

Copy the ROM to the root of the external SD card.

2. - Boot into CWM recovery mode. A simple method is to restart holding the buttons "up + down volume" down.

We can move on the menu with the volume up and down buttons and power to enter or accept an option.

3. - Install the rom with the option: Install zip from sdcard> choose zip from sdcard> Name_of_the_rom.zip

4. - When finished, restart and wait.

But when I do restart in CWM, there is no menu that appear, and so no possibility to chose the w30hd_drx_0.02.zip file

, I put on my SD card.

Did I do something wrong?

Sorry for my bad english, I'm from Belgium.

Hope someone could help me.

Thank you in advance!
