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. :)

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

/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...

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

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?

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?

Code:

-sh: kernel-config not found

time to reflash

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.

Code:

-sh: kernel-config not found

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 :)
