I have a problem with the 2011-01-17 version, in that when I transfer a file over FTP with AndFTP and at the same time try to watch a video in the Archos Video program, the system seems to bog down and the audio goes out of sync. or the FTP transfer fails.

This doesnt happen with the 2011-01-12 version, I can set up a download queue over FTP and watch videos or do anything else on the device with no problems.

This is with both kernels running at stock clocks, so I don't think its to do with that. If you want any more info or logs to help pin down the problem, just let me know.
[Gen8 Android Development] carlochiefsg:
Yes I'm interested. PLease email the guide to me @ carlochiefsg@yahoo.com.sg

By the way, I'm running on Archos 70 G8 250GB model.;) thanks lot

HI I'm using dogmaphobia's initramfs with your 2011-01-17 zImage. Is it normal if the system will freeze/hang after it went into sleep mode after 10 minutes with one of my any apps opened?
[Gen8 Android Development] davidthamwf:
Hi ardatdat;

First of all, thx for your hard work it really make our device become better performing....great one! =)

Anyway, i have discovered something about the bluetooth tethering. It crashes the system everytime you start it (i was using it tether to my iPhone for internet connections) Vanilla kernel was fine (I am using Urukdroid ver 0.3 boot from SD, the original kernel from him which is without the CPU clock speed tweaks, you can see all the standard clock speed choices under setcpu, namely 300, 600, 800 and 1000, 4 states)

Some observations:

1) Vanilla kernel was fine BUT if you set it to run full speed 1000mhz under setcpu (root + vernilla kernel) bluetooth tethering suffer random crash (might work for a while then the whole system crash, "random" means within minutes) If set it to "on demand" then it works stable without any hickups xD

2) Your kernel, the modified zimage, from ver 1 till now, none worked (i tried them all, even the latest version you posted, which reverted back the bluetooth driver. I was hoping it brings back bluetooth tethering but too bad T.T) I even tried set the highest clock speed to only 600mhz, with "on demand" mode, still crashes on me instantly after i switched on the bluetooth tethering.

So it seems it is both a hardware issues and driver/software/kernel issues. Varnilla kernel do crash if run under full 1000mhz, I would had think that it is due the bluetooth chip put inside was crappy stuff cannot stand the 1000mhz load, but hey if using your kernel it still cannot work even if i set it to MAX 600mhz. So this explaination wasn't complete.

While we can't change anything if it is indeed an inherent hardware flaw, we might be able to do something to the kernel / driver. The only differences btw your zimage and original zimage was, the CPU states (vanilla has 4 states: 300, 600, 800, 1000, and yours have 5 states: 300, 600, 1000, 1100, 1200 or 1280) not sure if you care to investigate the root cause? The bluetooth tethering is vital to this tablet since it do not have 3G, if you can help that will be a great news to all of us Archos gen8 tablet owners that followed your thread and uses your zimage..

Once again, thanks a lot for your great work and hope to hear the good news from you soon... cheers... :-)

[Gen8 Android Development] ardatdat:
Wow, thanks for your support. As I am not using bluetooth tethering and I am using wifi portable hot spot to share my 3G connection (thru wifi) from my Nexus phone (and sometimes from my wife's iphone). I really do not have time to test it on bluetooth. Actually, bluetooth is a bit 'old' nowadays and the speed is not fast.

If we are spending time to investigate into the bluetooth problem that can have a 'workaround' solution. Why bother? I know that it would be great to support bluetooth tether as well. Or maybe it is a hardware/software problem and will be fixed in coming archos updates?

So, thanks again for your support and I will really take my heart to look into the problems if I have time. :D Cheers~!
[Gen8 Android Development] pwhooftman:
I have also lag/freeze issues when using dogmaphobia's initramfs with the 1200 Mhz kernel. Especially when switching between applications. I rebooted to the stock Android system and the system seemed more speedy in normal use. Any idea why that is?

My 101 is stock, i.e. no external SD card, internal partitions untouched. Just installed SDE and your kernel as per post 1.
[Gen8 Android Development] carlochiefsg:
I gave up this kernel is full of bugs.

- bluetooth doesn;t work at all. Can't synch with my XtremeMac Tango microdock. The music was totally laggy.

- can't do internet tethering at all with Wifi hotspot neither will it work with BT tethering.

- The only plus point is it's able to over-clock up to 1280Mhz but keep freezing my system every now and then, render it unusable.

I restore back to Dogmaphobia's custom kernel. So far this is the most stable one of all. Everything back to normal now. Thanks for your good effort anyway.
[Gen8 Android Development] Big-A-Rob:
@ardatdat

I just have to say WOW. I tried using $auron's boot from sd method on my A70H and it was great work, yet unusable since it would not read the battery correctly. Anyways, I went back to SDE and just tried your 1280 kernel and it is blazing fast and smooth as butter. Fantastic work man. The Archos stock is pretty poor execution of utilizing Android imho...slow, laggy, could barely play Angry Birds or NFS, etc. Thanks to your work I might keep the Archos cuz I was ready to dump this thing. Where is your donate button at?
[Gen8 Android Development] ardatdat:
Thanks very very much for your support. (Although some ppl report having lag/freeze in the kernel, me & my friend are very happy with the newest 1280/1200Mhz kernels)

With the 1200/1280/1300Mhz kernel, we are able to play NFS shift without a single freeze, I am running in the world track now and a few days before, we install the spiderman from gameloft and work like charm!

For the 'donate' button.... I haven't registered a paypal account, and if you really want to give me some supports, I am registering it now (but it needs a few days for bank a/c verifications). By the way, I really not planning to compile a kernel for money. So, donate as you like :) Thanks again for your support.
[Gen8 Android Development] liutszho:
Sorry for a question outside of topic, but how did you get your archos connect to an adhoc wifi hotspot?

I thought archos can't see ad hoc networks.
[Gen8 Android Development] ardatdat:
Archos can see my nexus one's wifi portable hotspot (it is not adhoc wifi) coz the sharing is in AP mode.

In addition, there are many softwares to share wifi in android phone. For example: http://code.google.com/p/android-wifi-tether/downloads/list

Hope it can help you to solve the wifi tether problem ;)
[Gen8 Android Development] Big-A-Rob:
I do get a few freezes, but think that is more the lack of ram. I have noticed that archos performs much better when plugged in. At work I have it on the charger by my keyboard and it is a joy to use. When it runs off the battery it seems like they have some code to limit the performance to conserve battery or something. That may also explain the issues with it not waking up or shutting off while the screen is off. Have you seen anything in the code to suggest something like that?
[Gen8 Android Development] Kashban:
Same problem here (UrukDroid 0.4.2 initramfs & rootfs, ardatat's kernel, setcpu set to 300-1000MHz when screen is off). Battery is drained quick in that state, so it looks like the device freezes in a non power save mode. Screen is off, though, so the power consumption couldn't come from that.

Had no problems with $aurons kernel on that behalf and will switch back. OC'ing the device isn't worth the time I need to hard boot it almost every time I want to use it.

In addition one freeze occurred while using the photo frame app by Archos, but, to the kernel's defense, while charging, which introduces great heat to the part of the device where the CPU resides. Probably it was just to hot in there. Reducing the cpu clock to 1000 MHz while charging helped.
[Gen8 Android Development] ardatdat:
** Updated in the #1 post, the steps on how to use this kernel with the newest firmware + rooted **

Hope archos will release the source code for the newest firmware (well, the kernel is still 2.6.29...) and I will compile a new kernel after that. Otherwise, current overclock kernel works perfectly with the newest firmware. :cool:

** By the way, I have finally registered a paypal account. Feel free to buy me a beer (if you think this kernel really helps you) by clicking at the donate button :) Thx.

Does your kernel work with 0.5... I am having some problems trying it..
[Gen8 Android Development] parasaser:
hey friends

im new and noob.

i have version of archos 2.0.71

i root my archos with these tips http://xdaforums.com/showpost.php?p=10157349&postcount=4

and this http://xdaforums.com/showpost.php?p=9948644&postcount=1

now i need to overclock my device.

i download version 2011-01-12 (File name: zImage_archos_1200_ext4_fix05.zip)

and I replaced to zImage from root version(http://xdaforums.com/showpost.php?p=9948644&postcount=1)

then i open setcpu and i take autodetect device but nothing, always in 1000.

what is the fail? thanks for help and sorry for my english.

Hi,

Strange..... can't have More than 1950 in quadrant with o/c kernel...and stock rom.

Sommer people have More than 2500 !!!! How it's possible ?

Mu setcpu Settings. FOR SCORING

Performance

MAX 1280 MHZ

MIN 1280 MHZ

any idea. ?

Thanks.....
[Gen8 Android Development] nimrodity:
which version of the oc kernel works with uruk 0.5?

about the score till version 0.3 scores were much higher i had about 2950 with 1200mhz and 2300 with 1000mhz,now i get only about 1800 with 1000mhz,cant speak for 1200mhz because i found no version worked with 0.5

But if i knew before version 0.4 what i know now,i would have never risked my 0.3 with my class 2.The system was flying faster than ever,no comparision to newer version and because of trying 0.4 i bricked my SD,all other cant hold up the system speed althoug raw read/write speed was better.

BT tethering with Iphone 3Gs problem

I discovered that the machine must halt up once I connected to Iphone via BT tethering with OC kernel. :( Its also happened while I am using 2.0.71 firmware.

But this will not happen with non OC kernel, it is my machine defect or zimage problem?:confused:

Any friend have this similar phenomenon?:rolleyes:
[Gen8 Android Development] ardatdat:
Blue tooth is buggy. Use wifi tether instead :cool:
[Gen8 Android Development] cdelta01:
1200 is working for me. Its stable. Quad is 2200-2300. Note this is after I enabled swap. Without swap, its 1900-2100.
[Gen8 Android Development] lagoskon:
I also prefer 1200 because it seems more stable than 1.280 !

SetCPU seted to 1000 - 1200 On demand and A70 is super fast now.

Thanks for files.
[Gen8 Android Development] nimrodity:
does someone use the oc kernelat 1200 or 1280 with uruk 0.5

if yes which version of the kernel do u use.

I have fix4 but its not stable 1200,but with 1150.
[Gen8 Android Development] neonflx:
i would like to know wich init to use with 1200 kernel and uruk .5

Hi...i'm newbie here about my Archos 7o 250gb

i've some problem here...after install the SDE..i can't enter recovery mode anymore...

i try reboot then hold "Volume"...it's always enter the SDE (angStrom) not the recovery mode..

Now i'm used 2.1.3 Froyo...

(sorry for the english)
[Gen8 Android Development] Big-A-Rob:
If you hold the volume up and down at the same time you will boot directly into sde. Otherwise if you uninstall the android kernel it will boot directly into sde, but if you hold down the volume up OR down during boot it should go into recovery
[Gen8 Android Development] Caste23:
Is this kernel ok with 2.0.4 firmware ?

(I think yes but a prefer asking...)

thanks !
[Gen8 Android Development] ardatdat:
YES, refer post #1

Download the latest initramfs for 2.1.04 :cool:
[Gen8 Android Development] ardatdat:
Happy Chinese New Year :)

2011-02-01 (Newest)

- Rebase from the original kernel source

- Complier optimization

- Add interactive CPU governor

- Bluetooth fix (please test, should still have problems)

- For those enjoying online flash movie, e.g. myTV.tvb.com, please set the freq to min:1000/max:1000

- Set freq to min:1100/max:1100 for best 3D gaming experience

- Suggested to use with chulri's initramfs

Investigations show that if we overclock the MPU rate too much, the DSP rate cannot be set too high, otherwise, this will cause instability, especially in 3D gaming.

So, I have coded the DSP rate to a lower value when the CPU freq is at 1100/1280Mhz. On the other hand, if you want to have a smoother flash media playing experience, please set the freq to min:1000/max:1000. Otherwise, 1000/1100/1280 are ok for normal daily use.
[Gen8 Android Development] liutszho:
Can I integrate the overclock with the archangel custom scripts?

I would like to put the swap on my sd card instead with 1200

Edit: figured it out, make the sh file and execute it in terminal
[Gen8 Android Development] umberto.sulla:
Lot of problems with last release of the ROM and 2.1.4 initrd from Chulri on developer edtion.

At 1280 not stable at all, rebbots as I try to launch tests..

Uninstalled ...
[Gen8 Android Development] Caste23:
I have a lot of crashes with these kernels. Even if I set the CPU up to 1Ghz with SetCPU ... My Archos does not come out of standby.
[Gen8 Android Development] liutszho:
Tried connecting my apple bluetooth keyboard and it didnt work, guess bluetooth still freezes it.
[Gen8 Android Development] ardatdat:
After a lot of testing, I find out that the 2.1.04 official release is buggy...

The wifi is slower then 2.0.71 and the machine experience laggy. I am now using back the 2.0.71 firmware. :cool:

** For those having problem in using my kernel with 2.1.04, please reinstall 2.1.04 again.

A double installation (update firmware) will make the machine much more smooth.
[Gen8 Android Development] Sean35:
Agreed. It was buggy as all hell until I reinstalled firmware, now the device is smoother than it has ever been. Somehow I missed the 64 MB swap the first time around, I wonder if that has anything to do with it.

Hi,

I installed version 2.1.04 but I still have the same problem

it crashes always when it is in sleep mode.

:(
[Gen8 Android Development] corybucher:
I rooted the tablet already from 0.6 and then I went to this and did this to a t but now it says I don't have root access! Did I do something wrong???
[Gen8 Android Development] ardatdat:
Kernel updated in post #1 :cool:

Some A101 users report cannot boot from the previous kernel, so, this update should fix this problem.

For those still having bluetooth tether issue, please change to use wifi tether because it is more fast and stable. Thanks.
[Gen8 Android Development] corybucher:
Question: if I am already root can I just flash the new kernel or do I need to flash everything again?
[Gen8 Android Development] lagoskon:
Only new kernel(zimage) (through Developer menu) with the initframs of your firmware again. No need for reinstall everything
[Gen8 Android Development] corybucher:
OK, I did that but now it gets stuck at the welcome screen! any suggestions?
[Gen8 Android Development] lagoskon:
reboot it and boot into dev edition (hold speaker - , while booting) and wait some secs

Can I use this kernel with stock ROM?
[Gen8 Android Development] monkeydrufy:
sorry guys,

I've flashed this file

http://code.google.com/p/archos-gen8-dvb/downloads/detail?name=avos_2.1.04_tmproot.zip

now I have root but not overclock, why?

thanks
[Gen8 Android Development] ardatdat:
Because the zImage contains in your link is a default kernel

To OC, you need to use my zImage

Please refer post #1 for detailed steps
[Gen8 Android Development] topifone:
Do I need an external SD card or I can copy kernel to the buit-in internal sdcard of Archos? Also do I need Linux PC?

Sorry for a noob question.
[Gen8 Android Development] ardatdat:
No need an external SD Card.

When you prepare to flash the kernel and plug the USB cable to your computer, Archos will create a temp blank driver for you to copy over the initramfs and zImage. After that, click the power button to confirm the flashing
[Gen8 Android Development] topifone:
Thank you but I still have not root access. I'm on 2.1.13, not 2.1.14 Can you check?

When rebooting by holding volume - and choose Develope Edition, the screen blink 4 times then it boot to my same old version Android? I mean I see no differences?
[Gen8 Android Development] Sean35:
Right, SDE will otherwise look the same. Do you see Superuser in your list of apps? That should show you that it is rooted.
[Gen8 Android Development] topifone:
I don't see Superuser, that why i means it's not rooted.
[Gen8 Android Development] topifone:
Hmm it seems that I'm on 2.1.2 not 2.1.3. Sorry guys

Archos now have update with 2.1.8 with lots of changes. Hope to have new kernel for this update soon.

How will I know if its OCed? when I install Set CPU it only says 1000 not 1200 nor 1280? Which part I made wrong? But I successfully rooted the device..
[Gen8 Android Development] raymondht:
I Started by downloading this

Installed SDE...

then Downloaded...

"1D) For firmware 2.1.08, download the newest initramfs from here: http://code.google.com/p/archos-gen8...08_tmproot.zip" for my version...

- Then loaded everything... by following the intructions

- went to recovery console..

- Selected Developer Edition

- It took 5mins loading on Archos LOGO

- Good thing it is verified rooted 2.1.8

- Sadly Its not OCed, I installed SETCPU... the max is only 1000000

So do it again, 1 more time

"1D) For firmware 2.1.08, download the newest initramfs from here: http://code.google.com/p/archos-gen8...08_tmproot.zip" for my version...

and I download

1200Mhz version:

Download here: http://www.mediafire.com/?eo3cmqg64md7qdb for it to be 1200mhz...

- Then load everything...

- I combined the zImage(1200mhz) and the initramfs.cpio.gz(2.1.8)

- went to recovery console..

- Selected Developer Edition

- It took 30mins loading on Archos

- nothing happens.. it froze at the LOGO screen...

- restarted again go back to original...

- What do this is the problem? What did I do wrong?

- Please help me..
[Gen8 Android Development] ardatdat:
Seems to be correct procedure

Have you tried to reflash the official firmware 2.1.08 and try again?

Also, what machine you are using? A70 or 101?

And, you can also try my previous version of kernel and see if any one of them works for you. Thanks. :cool:
[Gen8 Android Development] woti23:
@ardatdat

i try to compile the kernel source from your github, in the .config there is a kernel command line with a 192.168.0.2 number and /dev/nfs

is this specific to your setup to test and i can safely remove the nfs related commans in the line or is it a nesassary hack?

trying to compile the kernel because of missing cifs module in UrukDroid
[Gen8 Android Development] liutszho:
Anyone else having this issue?

Games like Fruit Ninja lag a bit using the OC Kernel.

Its smooth on stock tho.
[Gen8 Android Development] daveid:
Just flashed using Chulri's 2.1.08 RW initramfs, initial bootup looking good, will report back after some playing today.

Quadrant went from ~1350 to ~1500, nice boost. Will know real world later today. Thanks!
[Gen8 Android Development] ardatdat:
No, I haven't modified this value. You can download the original source from official web site and compare the difference :)

SDE slower with 2.1.08 Initframs than Stock Android

I installed SDE a while ago, and rooted SDE a couple of days ago by copying over the initramfs and zImage files mentioned here:

"1D) For firmware 2.1.08, download the newest initramfs from here: http://code.google.com/p/archos-gen8...08_tmproot.zip"

I did not install an OC kernel.

When i boot into SDE, my Archos 101 is considerably slower than when booting normally, especially in opening apps, browsing folders, etc. It seems like the filesystem is slower. Does anybody have any idea why?. Aren't the initramfs and zImage in the mentioned zipfiles the stock ones (apart from root) so shouldnt i get the same performance as stock 2.1.08?
[Gen8 Android Development] topifone:
After flash zImage (OCed) and initramfs (2.1.08), my 70it runs smoothly. But sometime when waking up from sleep mode, LauncherPro keeps FC. I have the same problem with UrukDroid (that why I try this method). So I don't know it is a problem of what? If I reboot to android stock, it runs a bit laggy but LauncherPro is never FC.
[Gen8 Android Development] jonathanacohen:
Argh, help please! :eek:

I'm on Uruk 0.6.

I just upgraded to 2.1.08, then went in and applied the OC zImage and 2.1.08 initramfs.

Now when I try to boot into the Dev edition, the Archos screen appears a few times, and it launches the original stock install.

Any ideas? Thanks in advance...
[Gen8 Android Development] ardatdat:
Never have experience of LauncherPro having FC. Have you tried other version of LauncherPro ?
[Gen8 Android Development] Kashban:
Ok, tried the latest kernel with UrukDroid 0.6... devastating.

I just had everything on 0.6 as I wanted too, installed your kernel, did set it up to 1200MHz max, let it run a while, then freeze.

After reboot basicly every process FCs making the device unsusable and I fear I have to set up 0.6 again from the scratch. That hurts.

Probably my device cannot OC'd that much, probably it's some incompatibility between UrukDroid and your kernel. I don't know, but I know I won't try it again.
[Gen8 Android Development] Sean35:
You shouldn't have to re-set UrukDroid, just pull the initramfs and zImage from the UrukInstall compressed file and use those. When I realized that UrukDroid .6 doesn't mesh well with the OC kernel, I went back, and there were no issues. It would be awesome if the two worked well together, but what can you do? :)
[Gen8 Android Development] raymondht:
Do I need to do a Full Format? before I Do an install
[Gen8 Android Development] woti23:
thanks!

had a hard time to learn how to do, but finally i managed to compile the cifs and the nls_utf8 module ;-)

cifsmanager works with your zImage and uruk 0.6 initramfs
