Step by step guide: 48Mhz kernel and MMC boot clone
 

This is done on 770. I do believe it is applicable to N800 and N810, just substitute the right files will be fine. And again, the qualification for following this guide is: You have to know how to flash your tablet if you *****up.

770: MMC boot with Chinook and 48 Mhz kernel added. I would like to document it so that I can follow myself easier if I have to do it again.

770, brand new flashed to SU-18-2008HACKER_4[1].2007.50-6_PR_F5_MR0_ARM (2008He), use 4.2008.7-1 (2007He) is fine, dl from http://tablets-dev.nokia.com/. And of course, internal flash boot to proceed.

and installed from app manager, becomeroot, emelfm2, DiskUsage.

Add Fanoush's 48 Mhz kernel, http://fanoush.wz.cz/maemo/, scrolled down to " Support for SDHC cards and higher SD/MMC speeds for Nokia 770", dl http://fanoush.wz.cz/maemo/kernel-sd...2006.49.tar.gz and http://fanoush.wz.cz/maemo/kernel_flasher.tgz; both files dl to the default folder, /home/user/MyDocs/.documents, or Document folder from file manager. DL onto internal flash, not mmc card. If you are tight in space, clean up, delete/move things from folders Audio clips, Documents (all the user manuals) Images, and Video clips. And anything NOT related to this operation, delete/move.

xterm
sudo gainroot
cd ~/Mydocs/.documents
tar zxvf kernel-sdhc-48MHz-3.2006.49.tar.gz (this generated zImage-48MHz)
tar zxvf kernel_flasher.tgz
cp zImage-48MHz ~/MyDocs/.documents/kernel_flasher
cd kernel_flasher
./kernel_flash zImage-48MHz

This kernel flash leaves your apps intact. And if you know something about emelfm2 and installed correctly, you can have this all done on emelfm2, no command line.

Some good links, http://www.internettablettalk.com/fo...cessful+kernel.

Clone to mmc, I use 1 G Rs-MMC, use PB's clone scripts, http://www.internettablettalk.com/fo...ad.php?t=20534.
Scrolled down to "SCRIPT UPDATED 11:30EST 5/29/08, http://penguinbait.com/install-tools-ad.tgz and dl the install-tools-ad.tgz into flash, not MMC card.

Place in /root
open xterm
cd /root
tar zxvf install-tools-ad.tgz
This will then make /root/install-tools (it has to be in this location to work)
cd /root/install-tools
Now, carefully read PB's instructions regarding INTERNAL-txt.EXAMPLE and EXTERNAL.txt-EXAMPLE. The 770 has only one SD slot and is internal for the cloning. turn off swap file. Edit the INTERNAL.txt.EXAMPLE to your likeness, and rename it to INTERNAL.txt, and delete EXTERNAL.txt-EXAMPLE; This is my INTERNAL.txt file for a 1 G RS-MMC
" FAT 300
SWAP 128
1 ext2
TIMEOUT 10"

This should generate a ext2 600 MB and Fat 300 MB and SWAP file. and now,
Check:
There is only 1 SD card, right?
swap memory, uncheck, right?
INTERNAL.txt/EXTERNAL.txt only one exists, right?
Now you ready to go

./clone.sh

and wait.......; time to finish, with 48 Mhz kernel, 6.5 minute; without 48 Mhz kernel, 48 min.
Reboot and to add 64 MB swap file, with 48 Mhz kernel takes 7 min to make the 64 MB swap file; without 48 Mhz kernel, it takes 13 min to make the 64 MB swap file.

End product: a 770 running chinook+48Mhz on internal flash and MMC boot with chinook+48 Mhz and with over 300 MB for app installation. I believe, the 770 is more hungry for app installing space than the N8x0 as they have only 128 MB.

And the 770 is running just as peppy as my N810.

And now I will flash my 770 to 2007He and clone it to my 2G RS-MMC card.

My final configuration of my 770: 2007He on internal flash, 2008He on MMC and 2007He on MMC, both for ample app installation space, both over 300 MB space.

That's all folks.

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

Can I send my N770 to you so you can take care of it ? ;)
I will try this on mine. Thanks!

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

Absolutely YES. I love to play with it. But.......you? nhanquy? You are being humble. I learned most of my stuff from you. As a matter of fact, you read it carefully you can see where I plagerize from your posting :).

Again, anybody feel free to mail me your 770 I will be more than happy to take care of it, provide that it is NOT 100s of them :) .

Or, if problem, post here, we will help you.

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

rootsh is in Extras, might as well use that over becomeroot.

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

so, just to show my newbieness - what would this do for an N8x0?

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

It will make your N8x0 goes faster when accessing the SDHC card, may not be 5X like the 770, YMMV. And will ends with MMC boot with your choice of storage space. The main reason for MMC boot is 1) you can always fall back to internal flash if you messed up your OS as you are playing with the cloned OS from MMC 2) as much space as you want for app installation.

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

Not necessarily, and definitely not consistently. . . .

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

I think it definitely guarantee to make "accessing SDHC" faster, whether that translates to practical use is another issue, that is why "YMMV". Over the last two years, people has reported from "the best thing ever happened" to "no noticebly difference", as a matter of fact, I was in the "nay" camp. GA, you would like to comment about this?

On the 770, as in thread #1:

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

wow! I almost gave up my N770. Just to have it as a collection item ;) ! But after installing the kernel into the flash, the N770 is very responsive, very snappy!

My flash OS is 2007HE version 4.2008.7-1 and it is still OK. My N770 is dual-booting. The MMC OS doesn't show up but I think OS2008. Both are very snappy!

btw, bun, your link for the kernel_flasher is wrong. Please get rid the ";" at the end!

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

http://intr.overt.org/4.2008.23-mmc-kernel/

Is this kernel the same as fanoush's 48Mhz kernel ?

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

No. More info here, http://www.internettablettalk.com/fo...ad.php?t=21907

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

A couple of questions: is it possible to use the same procedure for OS2006? If not, what changes are needed?

Is it possible to use the modified SDHC cards for booting? I have a 8 GB card (http://www.remotefactory.com/n770memory.html ) that I would like to use.

I already tried cloning of OS2006 to this 8 GB card with these instructions: http://examplified.net/guide/Nokia_7...ting_from_MMC/

Cloning seemed to go well and I managed to get the boot screen to appear but booting from mmc2 failed. I also could not get the 770 boot from internal flash either (Nokia logo comes to the screen, progress bar moves from left to right, screen turns white and 770 boots again). Now I am reflashing the device.

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

http://examplified.net/guide/Nokia_7...ting_from_MMC/

is actually my preferred way to clone cards.

I think your cloned SD is ok but the flash is corrupted.

BTW, the modified 8G SD is nice but too expensive now!

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

OK, I think I just have to try again. I have now newly flashed and patched (high speed kernel and WLAN hot fix installed) OS2006 so cloning should go just right.

8 G SD is indeed nice. And at the moment it is actually quite cheap for people living outside US because the exchange rate for $ is really good. ;)

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

I got the modified SD card working (reflash, cloning of card without typing errors...). Nokia 770 became definately faster than it was before.

I tried to format the card so that the "memory card partition" (FAT16) would have been 4096 mb and the rest of the card would be the boot partition. However, the 770 only gives access to 2 G on the memory card. Also when I put the card to memory card reader and check it with Windows the card appears to be a little less than 2 G. The boot partition is about 4 G like it should be.

I checked the card with Parted Magic -live cd and it shows that the card has three partitions (one really small) and two aproximately 4 gigas. Where are the two missing gigas when I use the card on 770 (or Windows)?

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

We will find your 'lost' space together, how about that :) ?

1) dl and install DiskUsage from maemo.org>download or /gronmayer.com/it/, which give a breakdown of your disk use.

2) xterm

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

That is exactly what we are going to do but not this evening ;) Thanks for your advice, I will definatively look at your instructions when I have some time and post the results here.

Just to make it faster to get media files to my tablet. I have noticed that using a card reader is the easiest and fastest way to get the files to memory card. I have also Navicore installed that takes about 1 G and it has to have map data on memory card (if I have understood correctly). 2 G is also fine, I can always transfer the data to this free one giga space with card reader and move it inside tablet to internal memory. At the moment the problem is just that I don't have the missing 2 G space either on "memory card" or on "internal memory".

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

Is your preference 2007HE or 2008HE?

Before my recent WSOD (installing Canola borked), and a trip to Alabama repair, I had 2007HE running. I reinstalled 2006 as it was faster from the XP machine. I am going to travel and would like to install as you describe on my 2G card.

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

More details please? You're goin' to make a RAM disk thing or you're going to make a big .video or .audio folder in partition 2? You will have to SSH/USB or somehow get it on FAT then transfer to .audio, right? I am NOT sure this is faster. To access part2 or 3, you will need a Linux box.
In general, partition 2 is for app installation. I have 2.5G and have KDE installed. This left with 5.5 G for FAT or storage on a 8G card.

bun

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

Definitely 2008He with 48 Mhz kernel. Everything is eye-blinking fast, especially garnetVM palm stuff, maemo Mapper and Google map. You would NOT believe this is a 770. You would NOT. I cant get the speaker to work though. Listen thru a earplug is 100% fine. and plus some minor progs, skype, I like to run but have problems, mostly audio/visual, I kept 2007He for those apps.

bun

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

Sorry, seems like I mixed the partitions (p1 and p2) with each other. I don't need 4 G p2, probably 1 G would be enough. However, I would like to have as big p1 as possible for my media.

Actually, I think that I have located the problem: if I understand correctly FAT16 partitions may have a maximum size of 2 G. When I was partitioning the card I tried to make 4 G FAT16 partition (because for some reason I remembered that FAT16 partitions can be up to 4 G).

So it seems that I have to go through the whole procedure again... Or I could try to repartition the card with Parted Magic but I am not sure if it is going to work, last time when I tried to resize and move the partitions the whole card got messed up and I had to format it again.

I am using OS2006. It seems that the Diskusage app that you recommend is not available for this old fashioned OS. Can you recommend any alternative? And on the other hand: can I in any way make the p1 larger than 2 G (and accessible with Windows)? If I remember correctly the OS2006 can only read cards that are FAT16.

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

No. Linux kernel handles FAT32 just fine. Just format it on Windows and OS2006 will handle it (both reading and writing).

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

so, if I have already cloned my OS to my mmc, do I just follow the same steps as shown to the "Some good links" portion of the first post? Or do I have to re-clone my OS again? Or is there something else that can be done to use my already cloned card to get the 48Mhz upgrade?

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

That's it!!!
P.S. mind the links above are broke, use ones in first post (to lazy to correct tonight)

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

awesome! thanks for the response - but again my newbieness raises it's ugly (and stupid) head

so... as I was reading this post from Why there is lack of interest "Highspeed enabled kernel for the Nokia n800 and n810"? thread, what's the difference between the above ./kernel_flash and the fiasco-flasher being used?

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

They are the same before diablo we did not have fiasco-flasher on the device so we had to use kernel_flash. I haven't tried fiasco-flasher myself :D

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

so is one safer to use than the other? or just different flavors of the same thing? Basically I don't want to screw up my SD card (which I assume I run this on if I'm booting to it primarily) partition and have to redo all the stuff I've loaded...

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

hard to say without seeing source code of fiasco-flasher (it is closed) but most probably it does the same thing when flashing the kernel.

And BTW there is no fiasco-flasher for 770 or older OS versions for N8x0. I wonder if the binary would work with OS2007/N800 though. For 770 there is no chance.

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

Thank you for the info.

Now I finally have what I wanted: about 7 G as FAT32 on memory card partition and 1 G on boot partition. Card works fine on Nokia 770 and the partition sizes are as they should be. For some reason my memory card reader stopped recognizing the card but I can access it by connecting the tablet to computer with usb cable. This makes file transfer a bit slow but I can probably live with that.

One more question if I for some reason need to make the cloning again:
When following these instructions:
http://examplified.net/guide/Nokia_7...ting_from_MMC/

When I define the partitions in the following way:
umount /media/mmc1
sfdisk /dev/mmcblk0
/dev/mmcblk0p1: 1,15000,6
/dev/mmcblk0p2: 15001,,
/dev/mmcblk0p3:
/dev/mmcblk0p4:

What should I write instead of 6 if I want to directly make FAT32 partition instead of FAT16 partition? This time I just made a 7 G FAT16 partition and later reformatted it to FAT32 with Parted Magic.

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

b or maybe c, see e.g. this. No sane system checks this flag. It may help with the other ones though :-)

You can change it even now, see -c or --id option description in http://linux.die.net/man/8/sfdisk

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

Great guide! Only one slight correction to make:

xterm

where can one buy RS-MMC or MMCmobile for the 770? I looked at Amazon.com, buy.com, newegg.com, meritline.com. None of them carry it any more.

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

Just saw the post after sending you a PM :D

I have read somewhere we can just saw the SDHC in two halves.
Some SDHC cards have all circuitry in the bottom half and therefore we would not harm anything at all and we can simply push it in the rs-mmc slot to use it.

Has anyone done it ? I would like to upgrade memory for my N770 too.

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

No. I just tried it. SDHC is too thick, physically cannot get in the slot. Nice thinking. How about a regular size MMC, would it work?

Re: Step by step guide: 48Mhz kernel and MMC boot clone
 

well, i keep on correcting myself :)

Newegg carries 1g mmcmobile for $15 shipped, maybe 770 owners need to do some stock up before they all disappear like N800s.

They also carries 4g regular mmc for $21 shipped. Would anyone want to do some surgery on the 4G see whether it worked on the 770, cut it in half and see whether it still has a pulse ;) ?

Amazon.com has 2 G regular MMC $13 shipped (if order >25$) or 1G regular MMC for $14 shipped. They also has the RS-mmc 0.5G for $14 shipped.

Meritline.com does not carry even MMC any more.
