Well, I can report some partial success!

I was finally able to unpack a stock boot.img, modify the ramdisk (nothing major just a small tweak to test results), repack with another unsigned kernel, flash the new boot.img and get a good boot. I did this by using the kernel extracted from nemith's CWM image and not the custom kernel I've posted, so it seems like there is an issue with that kernel for now.

Anyway, I'll try and post some more files later but in the mean time I'm moving on with trying to get a CM7 ramdisk to boot.
[Barnes & Noble Nook Tablet] O_G:
I think this is now at a stage that it can be moved back to development.

Good work Guys!
[Barnes & Noble Nook Tablet] CelticWebSolutions:
Great to see you've made some decent progress. Sorry for my total lack of input, you're a good few steps ahead of me in developing. I'm still on a serious learning curve!

I'm getting there hopefully in time I catch up with you and give some decent worthwhile input!
[Barnes & Noble Nook Tablet] Goncezilla:
Hey if you have any questions throw them out there. I'm learning some things as I go along but don't have all the answers either. Hoping we can start combining efforts to move forward.

---------- Post added at 10:31 PM ---------- Previous post was at 09:31 PM ----------

EDIT:More progress!

Was able to get the stock ramdisk to boot using the compiled kernel I posted. I think the issues were with my compilers. No guarantees they are fixed but we are getting close I can feel it!

I'm not sure but I think this kernel can be overclocked, so if nothing else this should allow you to overclock a rooted stock device for now. I'll do some testing and get back....

EDIT 2:

Well it looks like this kernel should be capable of overclocking, but there are a few other bugs with it (could not turn on wifi) that still need to be worked out so I am moving on for now. I will post the boot.img if anyone else wants to play around with the custom kernel on stock firmware in the meantime.
[Barnes & Noble Nook Tablet] Goncezilla:
They had issue with wifi in the cm9 thread which they've now fixed. Perhaps some help from there thread will be available?[/QUOTE]

Good call, maybe we can leverage from them. I think I'm just missing a configuation setting in my kernel build but everything else seemed to be working so I'm not too worried about fixing it right away. Would rather get CM7 to boot ;)

EDIT:

Well more progress to report this morning! I've finally got a CM7 boot screen! I'm stuck in a bootloop but we are really close now!

Turns out my permissions were all jacked up on my system partition and it was refusing to allow the kernel to load divers. I've jacked with files so trying to get a good boot that I'm not even sure what I have right now, so I'll go back to square one and hopefully see a full boot :D
[Barnes & Noble Nook Tablet] Indirect:
Whenever you get a boot loop, I suggest that you get a logcat so you know what to look at. :p

No worries! You guys are doing great work. This was just a minor curiosity. The only thing I'd really like it for is a piano app (tough they're are some games/visualizers that are cool with more touch points). First things first!
[Barnes & Noble Nook Tablet] jsp254:
It may have been asked already and I didn't see it, but I presume with this being built from the cm source, it is based on what would be the newest nightly?
[Barnes & Noble Nook Tablet] Swiissjokr:
sorry if this is a noob question but once we flash this cm7 ROM, will we be able to have access to the nooks entire memory for whatever we may want to use it for?

EDIT: thanks Celtic, you da Mannnn! :)
[Barnes & Noble Nook Tablet] CelticWebSolutions:
We're working on mounting the memory as you speak :)
[Barnes & Noble Nook Tablet] pjdick:
If you are taking suggestions, one thing I would like to see is the ability to undervolt / overclock. I have a touchpad running CM9 as well, and it gets way better battery life than the nook tablet.

show-p1984 created a custom kernel for cm9 on the touchpad that lets you undervolt and overclock the processor. As a bonus, it can idle one cpu until it is needed....

[Barnes & Noble Nook Tablet] darthvince:
I imagine the screen off SOD and the brightness control not working are related. When you turn off the screen, it usually doesn't simply turn off, but it quickly turns down brightness before turning off the screen. There may be a way to disable the screen dim "animation" while the screen turns off.

I also came across this information that worked for the Touchpad. Might be worth taking a look at:

http://rootzwiki.com/topic/6909-new-sleep-of-death-bug-fix-for-cm7-that-works-for-some/
[Barnes & Noble Nook Tablet] Goncezilla:
Good input. We currently can push any clock speed we want but have not overclocked the kernel out of the gate. That will come at some point during Alpha (which should start soon).

As of right now we have the CPUs running frequency managers and are able to hot-mount processors (turn them on and off as needed to save juice). We will leave the battery life testing to all of you and tweak from there ;)
[Barnes & Noble Nook Tablet] Danrarbc:
If the brightness control has a /dev entry or something have you tried just creating a null device? That might work around it in the short term while we try to find the real solution.
[Barnes & Noble Nook Tablet] Indirect:
Alright, I'm finally awake and prepared to start tinkering. :) I'll see if I can figure out this little issue with the SoD. Gonce, do you have the files with working wifi?

For pretty much all of the last 24 hours Goncezilla and I have been buried in getting this rom to work. Well all our recent long days and night of endless hours have finally paid Off.

It's our pleasure to inform everyone that we have fixed everything in the original thread and now been sorted and we have now have what seems to be a stable and fully functional CM7 build for the Nook tablet.

We're going to do a little bit more testing for a bit then we'll put together a release :)

Goncezilla and I would like to say thank you to everybody that offered support and advice. Even if we didn't use your advice it was still very much appreciated that you offered it!

Send me over the files through PM celtic, I need to check a few things out.
[Barnes & Noble Nook Tablet] CelticWebSolutions:
Lol you just got thanked for asking the question because in a rush I clicked wrong button.

We'll be doing a write up explaining everything that was fixed and how it was done so everyone can see :)

Just busy working on a few minor things at the mo.
[Barnes & Noble Nook Tablet] Goncezilla:
Yep we fixed SoD, mic, screen brightness, mounting of partitions. You name it. We might go straight to beta.

Anyway we have some work todo, write-ups on what we have, how we did it and how you can get the beta. Also have to build all the packages. Should have something up soon so keep checking in!
[Barnes & Noble Nook Tablet] CelticWebSolutions:
Yes we're building things up but please remember we're tetsing as we go so it may take some time :)

[Barnes & Noble Nook Tablet] ktulu909:
How does the wifi power look?Range with the stock rom leaves much to be desired.
[Barnes & Noble Nook Tablet] Goncezilla:
It should be possible. Something to add in Beta though...
[Barnes & Noble Nook Tablet] PlacidCat:
I believe AdamOutler posted in one of the threads that there is absolutely no reason it shouldn't work - the chip is capable of bluetooth and the frequency of Bluetooth is the same as that of wireless networking and the two share the same antenna.

Question is, can you use both networking and Bluetooth at the same time. I thought I had seen some issues with the Nook Color regarding that but my knowledge is quite stale on the subject.
[Barnes & Noble Nook Tablet] Data Injures:
Apparently there's some activation code for bt that should be in the source but (surprise, surprise) B&N conveniently left it out. It's explained in the CM9 thread.
[Barnes & Noble Nook Tablet] lavero.burgos:
That is fine there is no rush take your time to build up everything properly so no oops i forgot something DL again :D. Not to mention Albert's v3 sdcard root method but hey that can happen ;).

I suppose its fair to thank someone for asking a details question over whining for releases.... but I thanked you back just to even it out :D

[Barnes & Noble Nook Tablet] lavero.burgos:
exactly, that code in NC was in line 119 in the kernel but in NT they have found nada so far, that code is a hit or miss + is very board-specific so other OMAP-4 devices won't help

What's the best route to take for root. I been reading about this nook for weeks but still haven't cracked it open just been busy with school. Thanks V :D

___________________________________________
[Barnes & Noble Nook Tablet] lavero.burgos:
Well that will be offtopic here but take a look in general section, my advice stay in 1.4.0 root use the normal "old" way to root i used Indirect's method and install CMW recovery by using Indirect's app. Why normal root? because i found it easier setup drivers if you have a well mantained pc than sdcard method that still you have to put work on it format it and make partitions, so its a big meh for me. I never had any problems with all this methods around, how come? im smart yes but here is a trick give maintenance to your devices and don't get crazy for first releases wait and see if it works for a fair amount of people, pay attention for any fixes and troubleshooting that comes out then go ahead and try it :D.

PS: any other question, doubt take a look in general section, post or PM me.

Building files now, make sure to get CWM going on your nook! :)
[Barnes & Noble Nook Tablet] Mephikun:
thanks for your hard work everyone! now for me to make a spinoff ROM. c:< credit would be given of course

also, does this run off the SD card?
[Barnes & Noble Nook Tablet] CelticWebSolutions:
Lol give us a chance to release it first before nicking it lol

We are building an sd version as well yes. Our main interest is internal though at the moment :)
[Barnes & Noble Nook Tablet] CelticWebSolutions:

Would a spinoff be something like miui?

Also, does this ROM have the status bar across the bottom Luke the stock ROM? Is this something that can be changed?

we're on the final stage but the long nights have had to stop (wives a bit stroppy) saying that it's already 1:20am here so I'm already in the dog house, I went to be for 3 hours at 9am today lol
[Barnes & Noble Nook Tablet] CelticWebSolutions:
In reply to those that are asking for an eta,

a great man on the forum once said

2 WEEKS :)
[Barnes & Noble Nook Tablet] CelticWebSolutions:
At this very moment in time that would probably be the easiest option!

WE've got a problem, the build we have on my device works perfectly in all ways. A lot of testing has been done on it including simple things like leaving it asleep with wifi enabled for hours to check for unexpected SOD and all works perfectly.

Problem is that we are trying to build an sd card which is what we've been asked for the most. For some reason my NT refuses to boot SD cards and I can't work out why. It's not even that the card boots and the OS doesn't load, it just ignores the card full stop!

So WE're at a bit of a loose end now, I've even tried downloading Adamoutlers linux boot image but even that doesn't work when written to sd. My NT just boots internal OS.

Until we work out what's causing the problem there can't be a release at all! I've even bought different (and hugely overpriced from PCWorld) sd's and tried those instead and it's still no go.

If anybody knows any little tricks that get NT's to boot sd then let us know!

It's all that's holding us up now!

When I get a bit of time later I'll post up a video showing how well the OS works, show you everything working test everything in the vid so you know whats in store for you :)
[Barnes & Noble Nook Tablet] Nuckin:
When you installed CM7, did you overwrite /boot?

And possibly did you repartition? try loading those files instead to where you mounted the sdcard in fstab, maybe the fstab is getting loaded earlier than thought and the bootloader is looking for those files instead on the 15GB internal partition, since I saw Indirect posted about mounting the external sdcard as /sd_ext

Just a thought, great work!
[Barnes & Noble Nook Tablet] CelticWebSolutions:
Thanks for the tip Nuckin but at the moment it won't even boot a straight forward sd with a boot operation of 50mb and some recovery boot files.

Here's the way I've been doing it

1. Load GParted in ubuntu

2. Create new partition table msdos style on sdcard which wipes it

3. create 50mb partition called boot with boot and lba flag in fat32

4. Copy boot files to boot partition(I was using goncezillas recovery boot ones to test)

5. Reboot NT and prey

6. Look rather said when internal OS boot up

7. Repeat till overly sad ....
[Barnes & Noble Nook Tablet] CelticWebSolutions:
Reeally? Shows how often I must have used the thanks buttons when I signed up, I didn't realise that!
[Barnes & Noble Nook Tablet] Nuckin:
lol, in the /etc/fstab file, try switching the internal memory back to /sd_ext and the external sdcard mount back to default external sdcard mountpoint
[Barnes & Noble Nook Tablet] lavero.burgos:
Meh i suggest votation :D, why sdcard hey not everyone have a 32gb class 10 :rolleyes: just my opinion, i vote for internal first :p.

Thanks for the hard work, well done!

~ Veronica
[Barnes & Noble Nook Tablet] CelticWebSolutions:
To be honest we knew the sdcard version was going to be the most tricky which is why we mainly decided to do that first while we still had some steam left!

As soon as the SD version is built and running we'll qhip up a cwm update.zip and post it up :)

You'll get it before too long ;)
[Barnes & Noble Nook Tablet] CelticWebSolutions:
OK Everyone lets not clutter the thread up with 100 posts saying if you want internal or sd.

They will both be released at the same time :)
[Barnes & Noble Nook Tablet] RandomMinds:
I had the same booting problem when trying to put my NT back to 4.1.0 until I used a card of 8gig or less. Then it worked like a charm.
[Barnes & Noble Nook Tablet] CelticWebSolutions:
Just nicked the wifes 8gb card from her desire z and it didn't work :(

Like posted above it's going to be one of those light bulb moments when I realise what I'm doing wrong!
[Barnes & Noble Nook Tablet] Nuckin:
did you try reverting the fstab?
[Barnes & Noble Nook Tablet] :
did you try instead on FAT32 just FAT.

I also didn't set the lba flag maybe that helps, I also did only create 1 partition with 50mb

nothing else.
[Barnes & Noble Nook Tablet] SCClockDr:
@CelticWebSolutions

Power + n maybe, from Power off condition?
[Barnes & Noble Nook Tablet] Data Injures:
You have your CM7 build installed on internal, right? Since it uses 2nd uboot, it probably doesn't get far enough into the boot process to read the sd before bypassing the bootloader... Maybe?
[Barnes & Noble Nook Tablet] strictlyrude27:
I had issues with AdamOutler's restore from sd method until I turned off lba and boot flags. Then again, this was with stock recovery so take that for what you will.
[Barnes & Noble Nook Tablet] landonotis:
My NT has been having problems booting from SD from day 1. The only sd card I have that works flawlessly is an old 128 mb partitioned with a bootable fat 32. Probably wont help you out at all, but worth a try.
[Barnes & Noble Nook Tablet] CelticWebSolutions:
I'm happy to report some sort of progress, I tried a little of what everybody said and eventually I have an sd that boots :)

No need to get too excited yet though, it boots but doesn't load the OS in the system partition, just goes black then resets and defaults back to internalbut at least the damn thing boots!

Out of all the tips everybody offered the one that did the job was the least likely. indirect suggested trying to do it in windows instead of in ubuntu like I had been, which amazingly enough worked first bloomin time! It booted with the box screen but couldn’t go any futher due to no files in system partition (windows couldn’t write the ext4 partition it just made). So on ubuntu I wrote the content of a system backup to the system partition, still nothing but it's a start!

So thanks for the tip xIndirect!

It's always the simple things!

Watch this space :)
[Barnes & Noble Nook Tablet] ae1990:
Probably the tool you used but there's one for windows.called mini tool partition wizard something like that which I used when my ubuntu 11.10 didn't write the correctly and I belive I could right an ext4 partition with it.

[Barnes & Noble Nook Tablet] ftokc:
Does all this require ext4? Duh? Have you tried dropping down to ext3 or even ext2?

My bad experience with linux and the ext4 format has caused me to at least ask the "dumb" question. :rolleyes:
[Barnes & Noble Nook Tablet] johnpence:
Just my 2 cents, I have had bad luck with ext4 also. Not sure what the benefits are over ext3 or 2 as this is something I know little about, but I couldn't get ext4 partition to boot when trying ubuntu on a usb flash drive.

Maybe try mounting as ext3. Again I am not a developer just a guy that had problems with ext4 booting and after I mounted as ext3 all was solved.

Sent from my Nook Tablet!
[Barnes & Noble Nook Tablet] stealthfx:
I remember there being an issues with ext4 and CWM, you had to get a version that could support\mount it. I thought I had bookmarked the topic a while back, but apparently not, let me dig around on my laptop and see if I can find the link...

---------- Post added at 10:08 PM ---------- Previous post was at 09:57 PM ----------

In hindsight, I am almost sure all current versions support ext4 out the box, so yeah, I just double wasted space on the internet. :(
[Barnes & Noble Nook Tablet] jsp254:
So... what you're saying is, in a perfect world, it takes windows and linux. Agreed!!!

Also, as much as indirect doesn't want to hear this... sorry bro... sparksco, in the evo shift forum, has 3 versions of cwmr that recognise and work with ext4. Redhat, bluehat, greenhat. Offered through cwm app pro. I think green is broke though. Currently using red. Again... sorry homey!

2) I don't like him because he's egotistical and has an insane superiority complex.
[Barnes & Noble Nook Tablet] ftokc:
So...what's CWM got to do with it? I thought he was trying to boot from a card without CWM. Now, I'M confused.:mad:
[Barnes & Noble Nook Tablet] johninsf:
I know this is re-stating the obvious on partitions...

"In order to boot into a partition, it must be designated as bootable or Active. Active Partition is flagged as bootable or which contains OS, this is generally a Primary Partition."

I also found this: "How to make a bootable SD card running CM7 for the Nook Color" just is case it uncovers something obvious.

http://bit.ly/uuAqPa
[Barnes & Noble Nook Tablet] CelticWebSolutions:
Thanks for looking that up but I'm happy to say we think we've already cracked it now and we have a fully function version of CM7 booting internally and on SD-card.

We’ve got some testing to do before we release but we should be releasing before the weekend it out which I'm sure you'll all be looking forward to.

I'll be putting up a video later if anyone is interested too ;) If nothing else the video makes me try everything so hopefully it all works nicely and you lot can have your Android CM7 tablet up and running in no time. Everybody had best start backing everything up ready to start testing CM7 for the Nook Tablet!
