Re: Overclock the N900?
 

still strange that some work and some do not.. do we all have the same n900??? or is just tat there are some conflict of softwares/drivers.. intersting..

Re: Overclock the N900?
 

It's quite strange.
I loaded ver 44 yesterday - no reboot loops no stalling at ubooting.
I must have had rebooted some times, though I can't remember how many.
Today I turned off, rebooted, and uboot stalled as described by others.
No way.
I had to restore a backup made with backumenu, and now I'm testing again.

Re: Overclock the N900?
 

Okay now I've found something strange which i've never encountered before when reflashing. I list them in points so hopefully it will be easier to troubleshoot or debug (anyone...? :confused: ):

1) The regular way of reflashing (i.e. run flasher3.5 -blahblah on Windows/Linux => power off n900=>press "U"=>connect USB)
does not work after upgrading to kernel-power v44 (+ uboot).
I've reflashed my device many times before without any issue and I believe I am already familiar with the procedure.

2) When connected to the PC usb port, the weird thing is both windows and linux (debian under virtualbox) cannot recognise the device
- device manager (windows): reloads once but no device seems to be detected
- dmesg:
[ 121.812147] usb 1-1: new high speed USB device using ehci_hcd and address 2
[ 122.367779] usb 1-1: New USB device found, idVendor=0421, idProduct=0106
[ 122.367779] usb 1-1: New USB device strings: Mfr=34, Product=38, SerialNumber=0
[ 122.369731] usb 1-1: Product: Nokia USB ROM
[ 122.369731] usb 1-1: Manufacturer: Nokia
[ 122.384473] usb 1-1: configuration #1 chosen from 1 choice
[ 122.400697] usb 1-1: can't set config #1, error -32
[ 123.164786] usb 1-1: USB disconnect, address 2

there . This has never happened to me when doing reflashing before.

3) At first when the device reboot into uboot
the screen backlight is on,
but after leaving the device off for a whole night, there was no more backlight but a dim screen when powered up again.

4) I can still see the tiny-teeny words on the uboot screen. Here two things happened:
- if I just leave it running, boot stops at "Starting kernel" forever;
- if I press any key as per the uboot onscreen instruction, I get a prompt, but it's no bash (well of course...) or any regular shell so I don't know what commands I can use here. Is there any "help" file or things like for this build of uboot?

5) Charging seems to be working in my case, though, contrary to some other similar cases. The charging LED is on and the device feels a bit warm. But I don't know how to verify or measure charging in this situation.

Some questions and hunches:
1) It looks like the device is not actually bricked but simply gets stuck at uboot and cannot load the kernel(s) successfully.

2) It is not dead hardware-wise either as charging is still working.

3) As so far I haven't succeeded in reflashing the device, is it feasible to set up a multiple boot environment on the device and work around the problem?

4) Or is there any other way to rescue the system besides reflashing?

5) I was just installing everything from the ground up after messing up the rootfs and did not install backupmenu or make any backup, so how can I nuke the whole thing and start afresh?

Please don't tell me this is no return ... :(

PS I have tried the Meego rescue initrd before, well it worked for me to rescue things in emmc and MyDocs, but this tim e it fails to break into the device just like the failure to reflash...

Re: Overclock the N900?
 

build44 has broken LED drivers. No RGB LED lights anymore.

Re: Overclock the N900?
 

Build45 is in extras-devel. Waiting for Titan for the changelog...
Thank you Titan for your strenuous work!

EDIT: installed ver 45 - the uboot penguin is there - system starts :D so far so good... now rebooting...

Re: Overclock the N900?
 

recently and accidentally upgraded with maemo44.....i saw the penguin that some are having problems booting. i activated a command called *facepalm* but after 10 sec......i got the progress dots and the n900 asked for my codes.....voila! successful boot! :)

Re: Overclock the N900?
 

changelogs of kernel-power are available in this link https://garage.maemo.org/news/?group_id=1528

for kernel-power 45 :
* revert to old binary u-boot image for now
* apply Paul Ferter's latest usbhost patches
* i2c battery patch by Matan to allow bme to start while bq27200_power module is loaded

https://garage.maemo.org/forum/forum.php?forum_id=6546

(eventhough i sometimes prefer to wait for others to try it and waiting for reports of problems, so i can decide whether to upgrade or not since i'm just a noob)

thank you titan

Re: Overclock the N900?
 

Tried the downgrading code "apt-get install kernel-power-flasher=2.6.28-maemo42 kernel-power=2.6.28-maemo42 kernel-power-modules=2.6.28-maemo42" but my n900 says Version "2.6.28-maemo42" for "kernel-power-flasher" was not found..

Re: Overclock the N900?
 

Please, please, please...

Could you explain a little bit that so called "facepalm"???

Please, please, please...

And thanks in advance!

Re: Overclock the N900?
 

What is it? It doesn't seem to be a command from uboot (enter help or ? or simply enter).

Re: Overclock the N900?
 

facepalm is actually a gesture... putting your palm on your face (forehead sometimes)

this will describes it better

Re: Overclock the N900?
 

For me kernel 45 doesn't work with nokia camera. f-cam doesn't work too.

Re: Overclock the N900?
 

look for titans updated fcam drivers

Re: Overclock the N900?
 

Audio/video problems with v44 and v45. Some times audios/videos are working after booting, sometimes not.

First sign of problem is during boot up, no boot up video (Nokia hands). When this happens, then no audio or video file can be run (error message).

Otherwise no problems with boot up or other functionalities.
OC (500-850), Extra Decoders Support installed.

Went back to v42 and all OK.

Re: Overclock the N900?
 

no audio and camera crashes instantly, an expected issues on a very experimental kernel.....this happened before then t'was fixed.....i believe it will be fixed again....not gonna downgrade...

:)

and hostmode is working awesome with v45

oops.....forgot bout configs.....OC using ideal settings @1ghz,
backupmenu with bootmenu-n900, no meego or nitdroid (or any other OS)

Re: Overclock the N900?
 

For those with camera issues:

1) Uninstall any fcam or fcamera package.
2) Reboot your device.
3) Camera should be working now
4) Install the *LATEST* fcam driver package. Not sure who has the latest. Ask here, or get people to update what is in extras-devel.

Re: Overclock the N900?
 

LoooooooooOOOOOOOOoooooooool

Re: Overclock the N900?
 

For those with camera issues... after install of kernel power maemo45... REBOOT THE DAMN PHONE INSTEAD OF GIVING IT IT'S NORMAL USAGE.. REBOOT AFTER INSTALL AND IT WILL WORK!
Btw: explaining what a facepalm is: LOOOOOOOOOOOOOOOOOL

Re: Overclock the N900?
 

Updated from 40 to 45 and new fcam drivers. No Problems at all so far. Thanks!


Question : It is still using the settings i made with kernel-config (250-1000 @ ulv). Is kernel-config still fully useable with .45?

Re: Overclock the N900?
 

where to get this fcam-driver update??

:D thx ;)

Re: Overclock the N900?
 

When I try to update the f-cam drivers from this post http://talk.maemo.org/showpost.php?p...postcount=5028 via the app manager I get an error. Uninstalling the fcam apps and fcam drivers and trying to install the driver from the post doesn't help.

Re: Overclock the N900?
 

Try

sudo gainroot
apt-get update
apt-get upgrade

I installed the .deb posted here and then I did that. Works like a charm on power43,44,and 45.

And question: Why is Titan updating the Kernel so much? Don't fix it unless it is broken, what was wrong with it? I have been running at 1150MHz for over 4 months and I have been doing just fine. What has changed? I am sure there is some reason (besides the addition of uBoot)

Re: Overclock the N900?
 

rofl, that amde my day, no offence

Re: Overclock the N900?
 

I know!!

he,he,he

I'm a NOOB!

Re: Overclock the N900?
 

Thanks a lot --- that is helping.

Re: Overclock the N900?
 

should i overclock to 250-1150 or 500-1150, and is there a difference when i play games between the two

Re: Overclock the N900?
 

the power kernel is not only for overclocking, many features & patches were added & needed for other programs to work, e.g USB host mode

it will be best if you want to update the power kernel you should read the changelogs https://garage.maemo.org/news/?group_id=1528 and follow threads that discuss the power kernel

if you think you don't need the changes in the latest power kernel & doing fine with your current kernel, then stick with it...

Re: Overclock the N900?
 

First: Titan's questions:
WAS stock pr1.3 kernel, no other patches or SOs or boot loaders running. I was highly interested in the usb host mode, not the OC part. So, no OC.

Here is my experience with power kernel so far:
Whenever I restart(not turn off and then on, restart) it doesn't. It looks like will reboot, but when it will boot, the light dims and no boot. Then, I have to turn it on in the "old fashioned way" (by holding the turn on button, the blue led lightning on and etc).

It broke my maemo-pc-connectivity. It doesn't work, even by reinstalling. And I really need it in order to get internet TO the fone FROM the pc(NOT tethering), via _USB_ (I have never been able to do it through bluetooth). My main interest was to get internet to the device via USB without the neet to maintain the PC on, but, no luck even to USB sticks.

I tried to get a Cyberpower CPH420MP(old-not manufactured anymore) self powered hub AND another self powered hub to connect something to it, and no luck. Then I tried to see if there was any readings in the energy coming fro the USB: No energy - zero volts.

I'll uninstall or reflash the pr1.3 back. I hope you guys be able to figure it out.

Thank you for your effort!

Re: Overclock the N900?
 

There won't be a difference because the cpu will run at max speed the most time.
Your phone will just be a bit snappier (and drains a bit more battery) if you use 500-1550Mhz instead of 250-1150.

Re: Overclock the N900?
 

I like to use uboot (or multiboot) to start Meego from my sd card.

Now i have installed the latest power kerner 45..

I have installed the raw image on the N900 itself:

Nokia-N900:~# dd if=/home/user/MyDocs/meego-core-armv7l-n900-1.1.80.4.20101102.1-mmcblk0p.raw of=/dev/mmcblk1

that does result in these partitions:

Nokia-N900:~# sfdisk -l

Disk /dev/mmcblk1: 979328 cylinders, 4 heads, 16 sectors/track
Warning: The partition table looks like it was made
for C/H/S=*/4/32 (instead of 979328/4/16).
For this listing I'll assume that geometry.
Units = cylinders of 65536 bytes, blocks of 1024 bytes, counting from 0

Device Boot Start End #cyls #blocks Id System
/dev/mmcblk1p1 0+ 24414- 24415- 1562500 83 Linux

Disk /dev/mmcblk0: 977024 cylinders, 4 heads, 16 sectors/track

/dev/mmcblk0p4 0 - 0 0 0 Empty

but when i reboot and i try for example:

run mmcboot

i get wrong image format for bootm command..

anybody know what that can be?


if i just let it boot i get something like

unable to read "boot.scr" from mmc 0:1
invalid partition #3

but what is that partition #3? i only have 2 partitions on it...

Re: Overclock the N900?
 

Please, if you run Titan's kernel-power ver.45, could you please see if your usb mass storage works when connected by usb to another computer? Mine doesn't - as well as other fellows'.

Thanks for responses. :)

Re: Overclock the N900?
 

You need the modded image (from codedrop) as described here. It contains a FAT partition with a uImage for booting using u-boot... ;)

Re: Overclock the N900?
 

ah so these:

http://repo.meego.com/MeeGo/builds/t...t-armv7l-n900/

or these:

http://repo.meego.com/MeeGo/builds/t...e-armv7l-n900/

will not work with uboot?

what is exactly the difference between those?

also the readme here:

http://tablets-dev.nokia.com/meego-codedrop.php

tells me that the images are now moved.. So i thought lets get those then.. But they are not really the same?

Re: Overclock the N900?
 

No they won't work with u-boot (unless they have already u-boot enabled them).

There's also a dual boot guide here.

I didn't see the notice about images being moved before. You could try out the image in:
http://repo.meego.com/MeeGo/builds/t...t-armv7l-n900/

BUT I have no idea if they have enabled them for u-boot. There was talk about creating weekly builds that would work with u-boot but I don't know if it's already been done (haven't tried it yet).

Try it out, and if it doesn't work stick with the "n900-final-mod" files in codedrop.

You can just update MeeGo from trunk (after installation and after You've booted MeeGo) as I've explained here.

Re: Overclock the N900?
 

I'm sure this has been covered somewhere in these 5000 posts but...

I have been happily overclocking using lv min 250 max 850 as my settings. I tried the ideal 500 850 but I noticed that youtube video's did not have enough juice and so moved to my present settings. Question...

What are the practical implications of my using lv 500 850 as opposed to lv 250 850? Obviously I am using lv because I want to conserve battery and don't what to compromise that. Will making my min 500 but keeping max at 850 while keeping lv really kill the battery? I know I could just try but I am not a good judge of how long it lasts and was wondering if others have already experimented and could give there thoughts. Thanks.

Re: Overclock the N900?
 

i just overclocked my n900 825 mhz !

Re: Overclock the N900?
 

is there someone has the audio and default camera issues on v45? it was okay for me yesterday with hostmode but earlier when i transfer files using h-e-n, the audio and camera issues re-appear.

Re: Overclock the N900?
 

geeze!!! now i cant even over clock!

time to reflash

Re: Overclock the N900?
 

For me mass storage works normally with power kernel 45. Maybe if you used hostmode before you connected to the PC, caused yours issue. I'm just guessing.

Re: Overclock the N900?
 

okay overclockers,

i really need help here. i already ran out of options. i re-installed kernel-power and after that, i cant even overclock.

the above error shows on xterm when i do kernel-config commands, yes im on root.

what i already did:
-reboot
-deinstall and reinstall power kernel, reboot
-downgrade down to maemo40, reboot
-reflash the software, then reinstall kernel, reboot
-still cant OC

what i have not done yet:
-flash eMMC (i cant do this coz im using win7 and even XP mode cant flash eMMC)

everything is fine, supported freqs are there (125-1159mhz) i just cant OC.

Please advise. and thanks :)
