@triplex76

if you can't see 600MHz's voltage value on UV app. you can control voltage on 600MHz.

this app get your voltage request And this app only decrease voltages.

the app is gui-front-end for sysfs.

xan said about detail ->http://xdaforums.com/showthread.php?t=829731

i checked MoDaCo Custom ROM r1(based JMI) and FROYO.OMJK2(original in my tab)

it woks fine all sensor.these rom is same result.

ok,i check old jk5 rom...Please wait ...

thanks.

Gyro n accel not working in euro 2.8.

Replace the sensor file won't work either.

Has anyone using 2.8 and got it works?

Plse share.
[Galaxy Tab  Android Development] koxudaxi:
@Gpsrisk

what rom did you use?

thanks
[Galaxy Tab  Android Development] Gpsrisk:
Koxudaxi,

Am using Modaco custom rom r1.
[Galaxy Tab  Android Development] triplex76:
Yes, but the voltage control app gives no voltage for 600mhz.... it shows only an interrogative mark beside the frequency.so you can't undervolt cause there is no initial reading of the voltage value.

I hope I've explained it well....

when you open the app you see for example:

800 mhz: 1200mV - what you set = final voltage value

for 600 mhz you get:

600 mhz: ??? - what you set = unable to set any voltage cause there is no initial voltage reading (???)!

it's unable to read any value and gives only ?

so I think something is wrong in voltage value layout for 600mhz ... or something is missing...cause the other settings work well

thanks a lot for the jk5 kernel... however the accelerometer issue seem to be there even in the JMx firmware.
[Galaxy Tab  Android Development] cx5:
Thanks thanks thanks koxudaxi

arigato-gozaimashta !!!!!!!! arigato-gozaimashta !!!!!!!!

You are the MASTER SENSEI !!!!!!

ok --> *** below report for sharing with forum members *** <-- hope someone reads it and don't make the same mistake as I did, hahahaha.

Hong Kong SGT, PDA = JK1, PHONE = JJ1, CSC = JJ3,

somewhere else says ZHJK1 etc etc etc, still RFS

quadrant score 1050 when new, drop below 950 after much used, much apps, install, uninstall, proximity apps stuck can't remove, etc etc etc, most significant problem is IO test 4 items very very very very SLOOOOOWWWWW one whole minute just for this IO test. Something is seriously wrong.

1st rotobackup - thanks !!!!!

2nd flash koxudaxi's zimage_hktw_2_6_3 using Heimdall_1.1.1

quadrant score 1150 :( setCPU detect 1000Mhz still .... obviously not yet setup properly. So on and so forth.

3rd flash zimage_hktw_2 using Heimdall

boot into recovery-mode

automatic start to convert RFS to EXT4 - took long time

reboot

Boot-loop

4th boot into recovery-mode, select RESTORE, select the file to restore - action - take not so long time

reboot

Boot-loop

5th boot into recovery-mode, check restore file, NO_MORE, select WIPE/factory-reset - action - took not so long time

reboot

Boot-loop

6th flash zimage_hktw_2_6_3

Boot-loop again

7th flash factoryfs.rfs from rotobackup (thank god)

Reboot

OK!!!!!!!! yeahh!!!!!!!!!

Contacts info gone, bcos I WIPE in above. But all apps appear bcos ROTOBACKUP is the best !!!!!!

quadrant score 2163 - still RFS - yeah !!!!!!!!!!

all these while 10GB of data in SDCARD all intact in one piece. No problems.

OK, gonna perform another factory-reset, give it a clean system then retest.

edit - hand-manually remove all apps, data, sdcard_data, etc, finally score 2267
[Galaxy Tab  Android Development] koxudaxi:
ok,Could you try it?

1: set voltage for 600MHz on the voltage app

2: adb shell (for login)

3: #cat /sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table

exp:# cat /sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table

0 0 0 0 75 0 0 0

you can't read 600MHz's voltage value.

but under voltage control is enable.

by the way, voltage table is it from voltage app source code what you say

i will change app again.

i don't understand about sensor problem.

why?

2_8 works all sensor on my tab.

i updated JK2(original) to "MoDaCo Custom ROM r1"

:confused:

What rom do you update from?

i suppose that previous rom is important factor.
[Galaxy Tab  Android Development] triplex76:
you are just in EXT4...

2200 score in RFS is no possible at all.

by the way koxudaxi I will try using ADB...

sensors are working...just accelerometer doesn't work for me ...

I'm gonna wait for your updates!

[edit]

ok, using ADB effectively it applies the voltage setting...so it's just a reading issue related to the app itself.
[Galaxy Tab  Android Development] Gpsrisk:
Kox,

I used only MoDaCo Custom ROM r1 all the while. Sensor works on your first euro_1.5 in my tab but need to replace the given sensor file. Once I upgrade to zimage

euro_2_8...gyro n accel sensors failed to work.
[Galaxy Tab  Android Development] koxudaxi:
@Gpsrisk

i may understand the sensor problem...

i changed sensor function don't need to replace any file.

Could you please replace to the original sensor file?

i put the original sensor file on this link.

http://koxudaxi.sakura.ne.jp/android/sensors.default.so

adb remount
adb push sensor.default.so /system/lib/hw
adb reboot

Good luck!!

[Galaxy Tab  Android Development] triplex76:
it doesn't work even replacing the file:

on JK5 sensors work.... only the accelerometer doesn't

on JM gyro and acceleromter doesn't work

replacing sensor file doesn't fix the issue.

you can see the accelerometer issue simply opening the gallery

[edit]

IT WORKS... i was just replacing with the old sensor file.... GREAT!

thanks

Hi triplex76

Thanks for pointing this out, very happy I've retained EXT4, but not so happy now that I know I've used this up. Hahahhaha, greedy me. Neverming.

I think you right-on 100000%. Cause reboot into "recovery-mode" I still see the [checking EXT-4 partition - passed]

So, I've managed to retain EXT-4 even after: -

flashing koxudaxi's zimage_hktw_2_6_3 over the version hktw_2 only

restore within recovery-mode using previously created backup file, I thought this would change it back to RFS.

wipe/factory reset

flash factoryfs.rfs from rotobackup, which was from RFS state. I thought this would change it back to RFS for SURE. hahahah. Seems not.

That's a lot I think ??? all without loosing data in sdcard and not loosing personal into and settings. Except lost contacts from the factory reset I think.

I want to reset to clear everything for a fresh start, recovery-mode WIPE is not effective :( any ideas/advice for me? Thanks !!!!
[Galaxy Tab  Android Development] cx5:
Hi koxudaxi MASTER SENSEI

I propose you to upload the 1.5Ghz and 1.6Ghz kernel for others to try, as we know some CPU can handle more while others not, hence may be someone out there may be lucky to benefit from your overclock kernel :)

[Galaxy Tab  Android Development] triplex76:
Hi koxudaxi,

while everything works , sensors included with the sensor file you attached, I found an old issue with CWM.(old cause it happens in old cwm i tried)

If you try to make a nandroid backup it starts and end without any error but if you look inside the backup you find that it just backups the external sd apps while system and data appears to be empty in fact their size is just some Kbytes.

In fact the backup itself lasts just a minute...when a full nandroid backup takes almost 5 minutes on mine with the current apps.

Another thing is that it creates the backup in the internal sd while in your previous 2.0 experimental kernel it backups on external sd....and it's a lot better cause the internal sd may become corrupted and you will lose data and backup too.

If you could fix those issues, reassuming:

-nandroid backup fully working and on external sd

-USB storage in CWM working

-update voltage-gt.apk to let it reads correctly the 600mhz's voltage...

I tested this kernel intensively and I found that the battery lasts almost 50% more than the previous 2.0 experimental one!

GREAT!

you will make me and other happy...;)

thank you for your GREAT work.
[Galaxy Tab  Android Development] koxudaxi:
Do you have battery temp problems?

if your tab gets high or low temps of battery then this kernel may solve this problems.

http://koxudaxi.sakura.ne.jp/android/zImage_eur_2_8_3
[Galaxy Tab  Android Development] triplex76:
no koxudaxi, no problem with the battery!

now I'm able to use the TAB 2 full days ... before one day and the battery was dead.;)

only issues I found :

CWM nandroid backup not fully working and backing up on internal sd while before it worked well and on external sd .

usb storage not working in cwm

other than that awesome kernel

[EDIT]

now i'm able to use the TAB for 3 FULL DAYS!!!

awesome..does the Vint change using voltage apps now? or you only decreased the voltage value and voltage apps continues to change only ARM voltage?

Just asking cause battery life is now AWESOME compared to the old kernels...
[Galaxy Tab  Android Development] richardtrip:

awesome..does the Vint change using "voltage app" now? or you only decreased the Vint value and "voltage app" continues to change only ARM voltage?

Just asking cause battery life is now AWESOME compared to the old kernels...

waiting anxiously for your new fixed kernel release ...

I would say to make if possible two different kernels...one with the richardtrip patch and one without...cause on JK5 firmwares there are no problems with battery sensors ...so maybe fixing something not required may translate in some other broken thing...but,of course, you know that way better than me.

Seems to me that the good old JJ/JK firmwares are a lot less troubles free than the newer ones and kernel modding requires to be divided in two branchs for old(JJ/JK) and new (JM) firmwares...I've seen some incompatibility from people reports...what works in one doesn't in the other and vice versa

I tried JM family and it has some bug here and there ... haven't seen pros to update from JK5 until now.

what do you think about?

waiting anxiously for your new awesome fixed kernel release ... again :p

@triplex76

I flashed eur 2.8.3 this morning.Came from v13 then modaco kernel with overcome rom. What uv /other settings are you using to achieve such amazing battery life. Thanks.

@koxudaci

Thankyou very much.Everything appears to be working.Battery temp stable @ 36deg with browsing.Maybe you can advise uv/other settings for lower temp.tq and rgds.
[Galaxy Tab  Android Development] koxudaxi:
hi,triplex76

"voltage app" can change two voltages .

if you set decrease value on "voltage app"

then the kernel decrease same value in two voltages.

i don't know about battery life because i only use for development and test.

i don't understand that purchase reason is using a phone or developing a kernel:p

i exactly think i want two branches.one is for older rom, the other version is for later rom.:)

[Galaxy Tab  Android Development] koxudaxi:
@dave18

thank you for your post

it's good.

@antiochasylum

I often tried 1.6GHz very unstable.

i could see "1600MHz" on cpuset. but,it immediately become freeze!!

android system was broken when it ran 1.6GHz

so i can't upload 1.6GHz Kernel .

it 's too dangerous...
[Galaxy Tab  Android Development] triplex76:
all settings -200mV ... rock stable! (but I'm using 2.8 cause >2.8.x are not so stable on my tab when changing manually cpu clock...it freezes sometimes...2.8 is rock solid.

you can see how after disconnected from the charger the battery will stay at 99% for a good amount of time while before it went down to 98% and so on in few minutes.after 12 hours of standby (night idle) it goes down 1%....amazing!:)

forgot to say I'm using cpu profiles:

screen off : 200mhz/200mhz previously I used 100/100 but I found caller ID lags to happear when clocked so low. (performance governor to avoid any locks!!)

normal use : 0mhz/1000mhz conservative

AC : 1000mhz/1400mhz conservative

extra speed is useless right now... there are not many apps that requires such performances, the only one I found some pros is when watching flash videos in streaming....for example using megavideo service....there some more mhz helps to reach 25fps constantly smoothing out the vid.

that's why I use AC profile 1000/1400 mhz...
[Galaxy Tab  Android Development] koxudaxi:

Hi koxudaxi,

CWM backup does not fully work .... it starts to backup on internal sd but jumps a lot of files...(it works good on external sd in 2.0 experimental kernel)

CWM usb storage doesn't work (doesn't work in 2.0 too)

I found the kernel based on the update1 to be faster and smoother than the older one ... GUI got a lot less delay during some specifical operation.

how to extract source code and build it.

$tar xf euro_soruce.tar (not update1)

$tar xf china_source.tar

$cd Kernel

$export PATH=/opt/arm-2009q3/bin:$PATH

$export ARCH=arm

if you connect a galaxy tab to a pc then the pc can mount internal SD and external SD on the galaxy tab while it go to recovery mode.

wow, now it FULLY works... thanks thanks thanks!;)

only small issue I found is that you need to reboot recovery from recovery itself to get access at both internal sd and external sd ... otherwise it mounts only internal sd at first boot.but this is a minimal issue.

i tried it. the result is very good.

1: go to recovery mode

2: select "mounts and storage"

no I was saying you enter in cwm and it sees only internal sd on the pc...after, you reboot cwm (from cwm) and it sees both internal and external sd ... small issue...
