[ROM] CM7 SD Bootable, w/ experimental BT working. - Nook Color Android Development

Notes: First off, I take no credit for this, other than posting it here to make it more visible to those who might otherwise miss this. This was originally made and posted by "verygreen" here: http://forum.xda-developers.com/showpost.php?p=12023893&postcount=7

btw, those eager to try external keyboard already can give it a try with all the BT progress made by fattire (the real hero).
Since I want to stay on the safe side myself, I compiled this 2G SD image that you can boot into and have working bluetooth (keyboard and external audio confirmed working). Of course use at your own risk and such:
http://handhelds.ru/nook/2g_bt_card_image.img.gz
go to settings -> wireless & networks
make sure that bluetooth is enabled and then you can explore and pair devices in "bluetooth settings" there.
Range so far is in the area of 13", so usable for a keyboard at least.

Hopefully the author (verygreen) will be able to post here and support users, especially since this is the first public SD build of CM7. I plan on trying this myself tonight, but since i am at work, i cannot do so yet. Any feedback will be great for the author and community.
Have at it folks!

You guys are absolutely amazing. I'm going to try this the first moment I get. I love this community!

U guys rock!
Thanks everyone for your hard work!

Just threw it on a Lexar Calss 4 8gb, and it ran nice, and discovered my eris via BT, but that's as far as I got. I plan to play more this weekend, but I'm sure everyone else will be playing with it in the next 15 minutes

awesome work! I think i may wait until it's incorporated into the CM7 nightlies as I like running from eMMC rather than SD, but good to see this getting going.!
good to see range up to 13'!
EDIT: whoops noticed it was 13 inches not feet. my bad!

planning on trying this out as soon as I get home. one question. what happens with the rest of the space on an 8 gig SD card? is it accessible?

You can just resize the 4th partition to take advantage of the whole card - otherwise it's lost
Sadly I booted it up fine and it looks great but I couldn't get bluetooth to turn on on my Nook. I also couldn't get it to connect to my WPA2 wireless so I had to reboot back to my usual OS. Looks promising, though

Just to dispel before rumors start or people say it doesn't work, based on what I read, it is 13" (inches). Think the original discussion said possibly 1-5 feet. Don't want people to walk 10 feet with their headset on and say there's issues...
GREAT WORK DEVS!

I have it on a SanDisk 4gb class 4 i think and running well. Does flash work well?

I wish I had a BT keyboard or gamepad to try this out right now. This is definetely one of the most important developments in Nook Clor history. The (affordable) ultra-portable hybrid netbook has finally become a reality. A huge hanks to everyone involved!!

how would I extend the partition? Through Disk Utility? I'm on a mac.

When I made my HC image, I had to use fusion and grab the partition app everyone on here uses for windows. All the terminal or disk utility commands said card was unwriteable. I bet there is a Linux utility that terminal will support, but I did not find it.
Good luck. Will post the app name when I am at my computer.

Sorry for the noob question, but is there any way I can get market on this? Not sure how to do it running off SD.

for some reason it isn't booting into cm7. I guess I am going to format the card and try again. Would the best way to format it just be to do it directly on the nook?
also easeus worked with windows bootcamp. It was easy to increase the partition.

I use parted and gparted on Linux to resize SD card image partitions.
Sent from my Nexus One using XDA App

got it running. seems to be running fine.
I know this is a stupid question because I'm sure it is answered somewhere but I couldn't find it. Does CM7 come with the market or do I need to download it? If so, from where? Thanks!
edit : OK I actually did find the answer. You have to flash the GAPPS separately. Instructions/Download link here.

I was able to get Market working on this SD image using the Honeycomb market fix:
http://nookdevs.com/Honeycomb_Google_Apps_and_Market
The only thing I did different was get the more recent gapps.
BTW - Thanks to verygreen for the first SD version of CM7 I was able to find.
I could not get Bluetooth to work (didn't spend alot of time.).
More Technical Information Proceed at your own risk
To extend the 4th partition I inserted the card into my Linux box and then deleted the 4th partition and then recreated it will all the space and then formated it with mkfs.vfat
Code:
# unmount all mounted partitions on the sdcard (A# is your sdcard letter like) sdd
umount /dev/sdA#
umount /dev/sdA#
# etc..
cfdisk /dev/sdA
# Delete 4th partition
# Recreate 4th partition as primary with all remaining space
# Set 4th partition type to 0C (same as 1st partiton)
# Write changes to disk
mkfs.vfat /dev/sdA4 #Should be the number of the new partition you set up.
It also mounted the first fat32 partition as my SDCard. I had to modify /etc/vold.fstab and change the mount partition from auto to 4 to get it to see the partition 4 fat32 partition.
Code:
adb pull /etc/vold.fstab
# modify /etc/vold.fstab and change the auto portion of line:
# dev_mount sdcard /mnt/sdcard auto /devices/platform/mmci-omap-hs.0/mmc_host/mmc1
# to
# dev_mount sdcard /mnt/sdcard 4 /devices/platform/mmci-omap-hs.0/mmc_host/mmc1
adb remount
adb push vold.fstab /etc/vold.fstab
adb reboot
Hope this helps and does not confuse!

Got it working with my foldable pda bluetooth keyboard. Im gonna see if i now cant get that bluetooth to work with froyo.

[ZIP][CM7] Nook Color SDcard and emmc swap!

Ok after many hours tonight I have managed to put together a couple .zip files that will install a modified vold.fstab on your Nook Color. (I am a total n00b at this)
The EMMC of the Nook Color has a partition for the ROM and a 5 GB partition that's mostly if not completely unused. Presently, there aren't any 3rd-party managers to move apps to that unused partition, so I modified the vold.fstab and am now able to use that partition for apps, files, etc.
NC.SWAP.VOLD.ZIP swaps the way the SD and EMMC directories are mounted. By swapping the mount points, and renaming EMMC to SDCARD, your apps, etc., will install to the internal storage, vs. installing to your SDCARD. Your physical SDcard is automatically mounted as "EMMC."
This also means that the music player still finds files, you can move files to "EMMC," and you can still eject the SDcard ("EMMC"), put it back in and it still shows up automatically. Now your NC won't freak out if you pull the card out without unmounting it - all of the apps are on the actual EMMC. You'd just find the SDcard under /mnt/emmc instead of /mnt/sdcard.
Because this ZIP file maps the change at an OS level, when you boot to recovery, your NC sees SD as the SDcard, so no issues occur. When you boot into your ROM, the mount points are swapped and you'll have access to the renamed "SDCARD" (5 GB) on your NC.
Use CWR 3.0.1.0 to install the .zip and check out the results with File Manager.
Thanks go out to Clark008, luciferii and Cali^Gal from #nookcolor, Loonacy and Raymondull from #Cyanogenmod, and EpicFail1236 from XDA.
Sorry if this is a bit crude, it's my first script ever. I would be happy to get any advice on how to make this better!
EDIT: I have been looking into renaming the emmc mount to say SD-External or better yet making it mount as /mnt/sdcard/sd-ext. it might be possible, ill be looking into it as soon as I can got laid up for a bit.
"Because this ZIP file maps the change at an OS level, when you boot to recovery, your NC sees SD as the SDcard, so no issues occur. When you boot into your ROM, the mount points are swapped and you'll have access to the renamed "SDCARD" (5 GB) on your NC."
/\/\ That clarifies a lot compared to the brief orig post. Will likely be flashing it this weekend.
BTW, if this expands and you need this 2nd post just have a mod give it to you. Thanks again!
BRILLIANT. Will be definitely testing this later today. Can't wait to run SD Tools on this
Sent from my NookColor using Tapatalk
it works! interesting how it'll work out as to unmounting, flashing roms. but with emmc being useless this is fantastic.
Thank you for the effort and time place in this mod
Yeah. The whole point of this was to utilize the 5GB internal emmc and not waste it. The next step is to mod the CWM to mount emmc as /sdcard so you can flash your zips from where you download them to (usually /mnt/sdcard/download), which in this case, goes to your emmc. But CWM will mount your external sdcard instead. For the time being, we can just put the zips we need to flash to the external sdcard, ie. /mnt/emmc.
I don't know if anyone noticed it yet, but if you usb mount after the swap, the transfer speed is kind of slow (~1.5mbps). I don't know if this is due to the emmc or that the read ahead cache needs to be tweaked.
We're open to make this even better. Feel free to comment and provide feedback.
This sounds like a step in the right direction, however, what I would like to see would be merging the emmc with the internal storage. What I mean is this; right now, when I go into "Storage", I see an "SD card" (8gb), "Internal Storage" (0.92gb), and "/mnt/emmc" (5gb). Why can't we combine the .93 Internal and the 5gb emmc together to make a 5.92gb Internal storage and eliminate the emmc from teh storage area? I'm sure there is a reason that I'm not aware of, but it seems that this would be the same as just about every other device. I am pretty sure the ROM is running from the emmc partition, so that has to have something to do with it, but I don't see a purpose for 3 storage places. I keep getting errors when I try to download apps and I don't even have very many installed. I have had to move most of them to the SD card to make room and some apps don't like to be installed on the SD card.
Another option would be to swap the emmc with the Internal storage. Then we'd be using the 5gb and the .92 gb would be sitting there doing nothing instead. Again, I'm sure there are reasons for this, I'm just asking to learn.
I agree.. ideally having the emmc mount be part of the system would be ideal.

i have no idea TBH but thats far beyond my ability. really it would be nice to symlink emmc to the SD card or the other way around. the issue is that you cant symlink with fat partitions :-/
This is neet. I don't know enough to comment, but it looks valuble for some people.
I just use my stock emmc for music storage and let apps sit on SD w/ videos.

No, but you can symlink to them. Why not set vold.fstab to mount the partitions onto other names and make symlinks named /sdcard -> /othername? That way, the symlinks can do their jobs or rearranging the namespace to suit our needs.
The ramfs isn't FAT32, is it?
I'm an old cmdline type, tricks like this are used all the time to fool software with stubborn opinions about filenames.

If this works as effectively as it sounds like it will it's gonna rock! With the multiple wifi/bluetooth file transfer options I can say bye bye to the need for an sd card!
EDIT: I think this thread is eerily quiet because of the popular advice written up HERE. Specifically #5...
IMO, with a great write up on the best ways to work with this, all of the things it will affect (positive and negative), and the proper words of warning then the individuals that take it upon themselves to modify their devices are the only ones that can be held responsible if it doesn't work out as they had hoped. They also have to understand that when they work outside the boundaries of an accepted "standard" that they are somewhat desolate and will need to come back into the fold before they can/will be helped...

This may be slightly off topic, but I cannot for the life of me figure out what that post is complaining/ talking about, I have had no trouble bouncing between HC, CM7 and stock.
All you have to do is flash to stock and then worst case you force the boot failure and the nook resets its self automatically
The last few posts on that message are myself and another person who have had not trouble with that now the OP hasn't responded so i'm not sure what to make up that post.
Is it real and an actual issue?
Or did the poster overreact to something?
Can some one please explain it to me if I am wrong about something in using a EMMC version of HC?

Seems neet to me also. Always interested in using both emmc and sd space.
@ chisleau - I like the concept of putting all my music on emmc. Do you use an option in CM7 to install or move all your apps to your SD card?
thinking out loud (and not actually doing it) -- but we know that /data is /dev/block/mmcblk0p6 and and the "media" or "emmc" is located at /dev/block/mmcblk0p8 -- can't we just repartition and merge the two?

ROMs that follow proper packaging - This emmc swap mod is one of them. So we're fine for those who are still hesitating.

Yep, I was hesitating, but between your post above and the "Thanks" from fattire to the OP, that is all the encouragement I need to take the plunge.
A few questions, tho, if someone can help me to understand this better....
I guess until I saw the OP, I did not realize that all apps in CM7 are installed to the SD card, as when I look at my installed apps in App Mgr, they don't show as being on the SD card. Is this some sort of CM7 voodoo or are my apps really on the internal memory?
Right now, with CM7, I am using the EMMC partition to store my music, under "My Files/Music". Power Amp can see this folder and it will play all my music just fine from within that directory on the internal partition, so if I install this update, what will that do to the 5Gb of internal storage I have now and the music on it?
Also, if I do install this update, what will happen to the apps and their associated data that I already have installed? Is this best done on a fresh build or will everything (apps/data and music) be A-OK after the Swap update is applied?
Just want to know what I am getting into by applying this update, as I have things pretty stable right now. If I could roll with apps on internal and music on SD, I would be more than fine with that, as long as I don't lose any of my apps/data/music in the process. If this is just mere partition re-naming/re-pointing, then I suspect my assets will remain intact?
Thanks to all who collaborated on this project!
why can't the entire internal partitions be imaged?
i use dd all the time to backup my sd card installs in case a test kernel or nightly goes poorly- or to burn a fresh install for multiple people. I just pop in the sd card into my laptop and burn the image back to the sd card.
if this was possible i'd have no issues with running off internal entirely if i could just burn the img. and get everything back as stock, including important device identifiers incase those were erased.
Need undo
This did what it's supposed to do but it seems to be causing a problem with the way I'm booting from sd. Is there a way to undo this?
Bump since I found this useful. +1 for CWM sdcard/emmc swap to enable SDcard-less flashing goodness from ROM Manager.

Just got DX2 and got questions.

Just got X2.
It was decent deal and I think I like it so far.
That said, I have couple of questions/issues.
#1. When I put my DX2 into my old holster, it THINKS that I am putting it into car dock and that annoying car app comes on and I have to manually turn off the phone. Is there a setting to disable this?
#2. I noticed that DX2 has 2GB root partition and 6GB partition which it mounts to /mnt/sdcard (HIGHLY annoying IMHO) and mounts external sd card as /mnt/sdcard-ext/
Is there way to re-partition and make it 8GB root partition and mount the external SD card as /mnt/sdcard?
I saw the thread regarding swapping /mnt/sdcard and /mnt/sdcard-ext/ but it does not appear too elegant. I wonder whether some kind of partition editor can be used to re-partition the whole thing around.
Thanks.

If u are rooted and flash eclipse u will have the sdcard swap included in the rom. Nothing else needed to do but flash eclipse.
And also...eclipse is just amazing anyway
Sorry not much else to suggest.
(Make sure u are on 2.3.4 b4 flashing eclipse 1.0or later)
Welcome to the x2...good to ha e u here...hopefully u don't become frustrated like some here have become with this phone. It can be a little finicky but it IS a very fine phone imho(except for the music stutter issues )

I understand that some ROMs will include the sdcard SWAP function.
However, I was asking whether we can make one gigantic 8GB partition for the system and mount the SD card under /mnt/sdcard just like DX.

Nope, can't do that. The only thing you can do is flash the SDCard filp-flop mod. This puts the SDCard as /mnt/sdcard and the 6GB (or what ever) internal storage as /mnt/sdcard-ext.
Hopes this helps.
Oh, referencing the holster thing. Two ways to fix that... First is kinda destructive. Find the little magnet in the holster and pry it out. (I don't have a holster so I don't know how easy that is to do.)
Second is easier. Again, I don't know if this works, but... Nothize, a developer in the Android Market created NoDock (NEED ROOT). It's $3.08, but he does have a trial to see if it will work with the DX2.
Ciao!

[Q] Access nook internal SD card from PC?

I am running CM7 Alpha Final on my nook, and before I installed it I repartitioned my internal memory on my nook using the method you can find on here (the command line one). Before I put CM7 on my nook, when I plugged in the USB cable it used to load the SD card, and the nook internal memory as two separate drives on the PC.
Now it only loads the SD Card, it doesn't even see the internal drive as being present. How can I get that to become visible again?

See, I did that already. I found the thread where the CM7 guys were trying to figure it out and apparently did add a fix (that I either don't have in alpha final or I'm doing improperly) and a link to a nook color app that I'm not sure works on my tablet.
Also a bunch of code in that thread I'm not entirely sure I want to try messing with just yet. So...
Any chance of help here?

I believe you need to edit your build.prop. Change the following lines to look like this:
ro.additionalmounts=/mnt/media
ro.vold.switchablepair=/mnt/sdcard,/mnt/media
Reboot and both partitions should be mounted. Credit to succulent for finding this out.

Hi
I am new to all this is so can you please be more specific about how to do this or is there a fix written for it.
Or has the final zip been repaired and updated.
Hope you or someone else can help with this, seems a shame for so much good work to be spoiled by this glitch.

You need to make these changes manually in a file called build.prop located in /system.
I made this change and I still only see my 8GB card labeled "removable drive" and 1GB labeled "My Nook when connected to my PC with USB storage turned on.
How do I access the remaining free memory in my 16 GB NT?
Yours is working just fine.
Right now, you only have access to the 1GB internal. You need to repartition your internal memory if you want to see the rest.
Cubanluke - you are always a good source for support - can you point me to a good link that explains how to repartition the internal memory?

It seems like a lot but its quite easy to follow if you read it and follow the steps exactly.

[Q] Which post instructions best to make n2a build equivalent?

Hi, in the Nook Development forums, I found this post from Albert Wentz: http://forum.xda-developers.com/showthread.php?t=1439630
But unless I'm confused, I believe there are many other posts with other roll-your-own instructions? Such as: http://forum.xda-developers.com/showthread.php?t=1466583
All I want to do is build the SD card for my kid's nooks (versus paying $20 to N2A) so I can boot to it to run Android just like the N2A card. Does anyone know which post N2A may have followed to build their version? Or is Al's post the most modern build? Or the 2nd URL I list?
I'm quite technical so know I can do this, I just need to know which is the latest and greatest, or if there are many diff build customizations, which, let's say, is the most popular ? I mainly care that it has Google Play and Amazon App stores, and that I can sideload ebooks, mp3's,videos. If it comes with other apps, fine, but I'm fine with downloading,installing any I wish afterwards.
And.....some posts mention you don't have to modify your nook at all, just boot to the SD card, but others say it modifies the Nook (roots it), so that if you ever had to return it you'd have to restore it (hence best to back it up beforehand). Which is correct???
Al's method works fine. Anything you mentioned that you wish to try will work. I ran boot to SD android rom for several months before I took the plunge and rooted my 8gb Nook to a full android tablet.
It in no way modifies the internal workings of your Nook. The Nook allows booting to the card by design. Just use a Sandisk card of 8gb or more for best results and all you need is a class 4 speed rating. Believe it or not, a class 10 doesn't work as well.

Al's method works fine. Anything you mentioned that you wish to try will work. I ran boot to SD android rom for several months before I took the plunge and rooted my 8gb Nook to a full android tablet.
It in no way modifies the internal workings of your Nook. The Nook allows booting to the card by design. Just use a Sandisk card of 8gb or more for best results and all you need is a class 4 speed rating. Believe it or not, a class 10 doesn't work as well.

OK thanks, so if I understand you, rooting is a separate method, as in my 2nd URL referenced. (and in reading that, the SD card is only used to flash (or pull) the image from, to put onto your Nook.) I don't know about backup, but I don't think I want to mess with the stock OS for now. Maybe if B&N abandons it. I guess I don't see it as a big deal that my kids will need to reboot each time to toggle between nook OS and Android.
I read that about the Class4 vs 10. I think I even read posts about class 10's not only running slow, but acting really buggy? Is that right?... One of our SD cards is a 16GB class 4 and a 8GB class 6. Anyone heard if class 6's have any issues?
Extremely easy process to build a card similar to N2A to run a very stable CM10 from:

Ooops!
I just realized both URLs I posted (even 1st one from Albert) mention rooting.(altering tablet) My mistake. Ok, so where's the mainstream single post on XDA forums that describes the most popular non-root (boot to SD) process? I'd rather follow a post off XDA website. And if I have issues, maybe fallback to that URL you gave me, although his English is not so great, so afraid I might get lost in his partitioning instructions. I also don't have a Linux box at home (re: his mention of EXT4) although I have been trained on/worked with Linux some. Although running Jellybean since it's the latest & greatest sounds nice....although I've read enough articles from mainstream tech sites that state it's a bit too buggy? I'm sure ICS is plenty good enough and all apps support it.
Whats the difference between CWM (clockwork mod) and CM (cyanogen)? Wikipedia just says "The CyanogenMod source code repository also contains the ClockworkMod Recovery"

The step by step you'll find somewhere here on XDA actually is the work of the guy I posted to. So my link is the source. That "Iamafanof" blogger is the person "Succulent" you'll see referred to here at XDA. Entirely up to you of course, but I don't see why you wouldn't at least check it out.
Edit:
You do not need a Linux system and I don't know what gave you the idea you would. The process is extremely simple: Download a rather large file, burn it to an sd-card, expand one partition (optional but recommended).

I thought that because as far as I'm aware, the EXT4 that he mentions (for P3 Data1) is a linux type partition. (unless some Windows partitioning tool can create it I'm not aware of) I'm willing to try his steps. So I guess you'd recreate the "P3 FAT32 SDCARD" partition the same size as it was before then? And the P4 (EXT4) you'd resize, as you mention, to take advantage of all the rest of the space on your 8 or 16GB card. But what free tool under Windows can create EXT4 ?

You do not have to create any EXT4 partition. Nor any other other kind of partition. All you have to do is expand the FAT32 partition. MiniTool is free and will do that for you.
http://download.cnet.com/MiniTool-Partition-Wizard-Home-Edition/3000-2094_4-10962200.html
Edit: And, FWIW, I went and checked. Mini Tool can also create EXT4 partitions, should you want to.
I got that image onto the SDcard, it now has 4 partitions:
BOOT 249MB (FAT32)
350MB (EXT3) 91% used
600MB (EXT3) 3% used
SDCARD 713MB (FAT32)
13GB Unallocated
So I would right click partition "SDCARD", extend it to the 13GB.
But, in his post he mentions one partition (P3,DATA1, which MiniTool doesn't show any partition labeled as such, but I assume he's just talking about the 3rd partition (the 600MB Ext3 partition) being used to store just apps & app data. (I assume since it's EXT3 which is compat w/linux i.e. Android) If so, what do you think..is 600MB enough for downloading/installing lots of apps? Or is it wiser to extend it to maybe 2 or 4 or even GB? For example I have the Humble Bundle games for Android Tablet. The installs (APK) are huge...anywhere from 30-200MB themselves..... I assume their post-install size takes up a different amount of space (more) than the APK itself, just as with Windows EXE installers? And if I recall correctly I believe once installed, you can del the APK... Anyhow, I'm emailing the company to see what install reqs for disk space are, since all they list the APK size.
Only you know how large data partition you need but it sure looks like you need it larger than 600.
So, to add some sort of instructions:
Delete partitions 3 and 4 (the 600 and 713 MB ones)
Apply changes (top left)
Create a new partition 3. Make it EXT4, Primary and the size you want
Apply changes
Create a new partition 4, FAT32, primary to pick up whatever is left unallocated
Apply changes
Don't forget to "apply changes"

Although all apps downloaded from Google Play will reside on /data partition, many apps keep their data separately in the internal user-media partition or on the external SDcard (the 4th /sdcard partition in your case). For example, I have a video game app which takes ~30MB for itself in /data but ~350MB for data storage on the SDcard. The Titanium Backup app works the same way. So you'll have to anticipate not just the app's storage size requirement but also its targeted partition for data storage.
Does this also work for CM 12?
Can these instructions be used with CM12 Lolipop?

Yes, if you can find a CM12 ROM image that was specifically compiled to run on SD.

Where can I find that ROM image? I haven't had much luck finding such a ROM, I haven't seen that specified.

I am not aware of any CM12 SD-based ROM build for the Nook Tablet, but you can find CM11 SD-based builds for the NT at https://iamafanof.wordpress.com/category/nook-tablet-2/.

Delete sdcard and mount extSdCard

Delete sdcard and mount extSdCard 16 gb as internal memory.
How to? i have small memory on Samsung b5330 2GB only, and i want to install more apps... and some games, how to delete sdcard i don't need it and mount the extSdCard as internal. Thank you

Well, no reason to just disable it. You can swap them however, though with the limited available development for your phone, there doesn't seem to be any out of the box solutions. You'll either have to try an app like this: https://play.google.com/store/apps/details?id=eu.codlab.int2ext or follow a guide for say, an S3, and mod that to reflect the correct partition mounts and names for your particular phone and update. For some phones, a compatible kernel is needed for the swap. If that is the case for your phone, you are probably out of luck since there doesn't seem to be much of anything like that for you. Make sure to not only back up your phone, but internal and external storages before attempting this. Would also be good to be familiar with how to flash back to stock with Odin since that's about the only option you have to get back to normal if things don't work right.
NO problem
Is not a problem to do format with odin, i have root-it the phone, i have change some times andoid version on it, i don't care about apps, i have all apps on my pc. i tried more commands with terminal emulator.. no Lucky. i will try this app,
i try to modify "vold.fstab" but nothing changes except on start up, all apps has crashed. and i am sorry for my bad english.
I have a problem, now my extSdCard is same as sdcard folder, and sdcard folder has no changes. are the same... any ideea
Now finaly working, i have changed where normal i have to write path of internal name o /mnt/sdcard to extSdCard and for external i have write /mnt/sdcard now is working .. i have inverted the names.i have loot of memory now how to make the 2 gb of memory work as swap? or lass 512.. becouse i cant see it anywhere.:good:

Good job! As far as the swap - are you referring to virtual RAM swap?

Yes, Virtual RAM swap... i have made it on sd card
dd if=/dev/zero of=/mnt/extSdCard/.swapfile bs=1024 count=94288
mkswap /mnt/extSdCard/.swapfile
chown root:root /mnt/extSdCard/.swapfile
chmod 0600 /mnt/extSdCard/.swapfile
swapon /mnt/extSdCard/.swapfile
But i can't find anymore the 2 gb sdcard, is only my ext sdcard working :laugh::laugh:

Yea, not so sure about that part, unfortunately. I haven't had to do that manually before that didn't already have an established method for the particular phone. Glad the main part is working though!

That part will probably be pretty tricky because there isn't really any development for it, and almost certainly no source code to build the kernel yourself. Your best bet is to check out some other phones that use the same chipset that might have some development that you can kind of piggyback off of. These other phones would be similar: http://pdadb.net/index.php?m=pdamaster&posted=1&cpu=a21654
It looks like the Galaxy Y Plus (i9001) has a decent little development community. The guys there would probably be more helpful with figuring out stuff to do since it has a similar processor. Might try to befriend a kernel dev there and see if they could give you a hand.
