I tried about 6 times... Power on with N held, hold power.. Release power 2s after Reading message, N button after Reading message goes away. Nada.

Also tried several times to use various apps to reboot to recovery, nothing.

Maybe it requires CWM installed on eMMC? I'm still stock nooted. :)
[Nook Color Android Development] DizzyDen:
If the SD is in on boot... CWM on eMMC shouldn't matter... here's what I have found works flawlessly....

With NC completely powered down... (by holdin the power button until it shuts off)

Press and hold "n" key.. (you will keep holding this until you see the penguin)

Press and hold "Power" key for 5 seconds AFTER the "touch the future" screen appears (If you have OC kernel... may have to experiment with slightly shorter times)

release "Power" key while keeping "n" key pressed as mentioned above.

Hopefully you see the penguin and it would install the .zip files....
[Nook Color Android Development] mrmark93:
Release the power button a few seconds into 'Touch the power...' and don't let go of the 'N' until you see the Penguin.

I'm also stock/rooted (12-18 Autonooter), using an SD 4gb Class 4. Ran N31 w/overclock, 1100@performance governor, got a few 2000+ quadrant scores. Blue-tooth A2DP works for about 2 feet for me; HID mouse worked, but was wonky as far as function-landscape was sideways :D I am thoroughly impressed with all the work done on this little tablet. Once the 'tablet tweaks' and the final video changes make it into the nightly, I'll be completely where I thought this could go. Thanks Verygreen for putting this together, and all the other developers for their amazing work!
[Nook Color Android Development] khaytsus:
Okay, make that 8 times I've tried now :( Same thing each time. It just boots normally every time.

Wish reboot recovery worked... That'd be easy.

Okay, I think crazy is loosely defined by trying the same thing repeatedly and expecting different results, but after a few more tries I managed to make it work. ;)
[Nook Color Android Development] clamder:
i've only used sd card builds of nookie froyo and hc. never used any emmc builds before. i just used this method by verygreen and it works great.

however, i want to ask. is there significant performance improvement by installing cm7 onto the emmc? i ask because i have a class 4 sd card and i've oc'd to 1100mhz. i notice that it has trouble downloading multiple files. just wondering about others that may have installed the emmc build along with the sd card build to see if there's any significant gains. thanks!
[Nook Color Android Development] clamder:
i had it reboot normally twice for me. i just held both buttons longer than usual.

basically, power off completely. then hold n first. hold the power button while the n is held. after about 5 seconds, the initial words should appear. keep both held for another 3-4 seconds, and then release both. that worked for me.
[Nook Color Android Development] khaytsus:
Same here, anything >1M isn't going to download reliably... Some folks on IRC told me this is a problem running from SD but not eMMC. I'm going to try increasing the SD card buffer to see if that helps.

Hard to tell if I want to go down the road of installing this internally or not with this going on ;) Otherwise, it's working really well!

That said, can this be installed internally once it's set up on SD? Just curious, I've been setting it up a fair bit on SD but without any big expectations.

Thanks verygreen, this makes it VERY easy for folks to try out CM7 :)
[Nook Color Android Development] dmoneypros:
Got this up and running...very easy...THANKS!

One problem I'm having is when the screen shuts off...I press the power button and it doesnt turn back on...I have to hold the power button for 20-30 seconds, a couple, sometimes a few times for it to reboot.

Edit: Also after a normal shutdown then trying to boot it back up hitting the power button does nothing...I have to hold it down for 20-30 seconds...on the 5th+ try if i'm lucky it will turn on

Edit 2: After experimenting for a bit, it only now boots when plugged into the computer (every other time)

Maybe a bad root? Does this with or without the SD card

Any help is appreciated!

Thanks.
[Nook Color Android Development] svennn:
I set this up for a family member yesterday and it works great.

I have one question though. I know that on the Honeycomb version, the kernel will not sleep effectively burning the battery quite fast.

Does the CM7 kernel have the same issues? As an example, on HC, my battery would drop 10% overnight with no use. The stock rooted ROM has no drop or about 1%.

Thanks,

Steve
[Nook Color Android Development] DizzyDen:
When the screen shuts off... use the "n" button to wake it... try powering off with the menu option you get when pressing power... this will allow the system to unmount the SD and close up any files needed to be... may fix some of your issues...

Additionally...

I would restore the original boot in eMMC... u-boot.bin, uImage, uRamdisk, uRecImg and uRecRam and see if it boots normally without SD card....

Assuming that fixes that part of the issue... set up the SD card again from scratch... make sure to boot it each step of the way.

You can expect to see the same battery drain on CM7... it has to do with not placing subsystem components in sleep mode to avoid the SOD issue.... perhaps down the road they will look into deeper sleeping certain subsystems, but they are working on more pressing issues at the moment.
[Nook Color Android Development] sark666:
This installed fine, gapps too. Put it on an 8 gig sd card. However, I don't see the other partitions as described in the instructions. When I put the sd card in my computer I just see the boot partition.

On the NC, if I go to mnt I see sd card. From the terminal program, it looks like it has 5.9 gigs free.

Is there a way to mount this in windows? I was expecting to see a separate fat partition.

Edit: Also if I hook the NC up to my computer via the usb cable, is there a way to access the partitions?
[Nook Color Android Development] quinxy:
I don't get it, my system will be fine sometimes and other times it barely works. In particular, I try to run Dolphin Browser HD and it'll partly load news.google.com, the progress bar hangs around 90%, content is on screen, and then suddenly it crashes and won't restart, default browser won't work then, few other things will work (nothing which seems to require su). Or other times I'll suddenly get a bunch of "force close" windows. Anyone know what might cause these? I did the CWM fix permission thing, and have cleared the davlik cache dozens of times now. Tried the latest Delingrin kernel, the one before that, and the stock one. Tried with OC, now OC is off, same deal.

Help!?

[Nook Color Android Development] epakrat75:
Just wanted to say thanks again as I just used this to update to RC4. FWIW, I'm not rooted on the eMMC. Now my NC is hardware accelerated and video works under GB! Flash / Youtube confirmed working. All I did was write the generic image in the 1st post to my sd card, copy the RC4 and GAPPS signed zips to the root of the SD card, eject from my SD writer, put in NC (while off) and power on after insertion. The install went great. Also using an app called SD Speed Booster to set Cache to 3072. It's as least as fast as running from eMMC IMO. Using a Sandisk Class 4 16GB SD Card :cool:
[Nook Color Android Development] DizzyDen:
This is actually normal. Since all 4 partitions on the SD are "primary" partitions, Windows will only see the first FAT or NTFS (which there isn't). There's a utility to mount other partitions in the NC available in the forums.... note that if you use it... I believe you have to disable compatibility mode (spare parts) and USB Debugging mode (CM7 Settings).

Seen Dolphin HD cause this a lot on my NC... which sucks coz I like the app... seems like once the FC's start... other apps start FC'in also.
[Nook Color Android Development] quinxy:
I seem to have resolved the Dolphin problems by uninstalling and reinstalling, but now I get gapps and google framework force close messages every few minutes or hours. :( Getting sick of rebooting this thing just to use it for 10-20 minutes at a time. Not sure what to do other than start from scratch and reload RC4/gapps/my apps.

Q
[Nook Color Android Development] sark666:
Thanks I'll look into methods of mounting the sd.

I was curious if the [CM7][WIP] Honeycomb/CM tablet tweaks work with this.

Anyone try?

http://xdaforums.com/showthread.php?t=1002000
[Nook Color Android Development] 12paq:
yes they work.

I do have a bug with the Android keyboard when the status bar menus are set to the top. Not sure if this is the tweaks or the sd bootable version, no biggie because I prefer them on the bottom.
[Nook Color Android Development] gallahad2000:
Anyone having trouble with facebook? I installed the CM7 nightly 177 to an SD card for a friend of mine and they're reporting facebook FCs every time they try to open it. They've already tried uninstalling/reinstalling.
[Nook Color Android Development] maltydog:
Downloaded...some interesting apps, but not the problem. Some apps have a download link (Titanium backup) some don't (like Facebook and Kindle). This seems to be a limited version of Market. I will do some additional looking to see if I can figure out what the problem is.
[Nook Color Android Development] gallahad2000:
This is a known issue with new market. It blocks apps that it doesn't think will work with your device (facebook and twitter because the NC lacks camera and gps). A stop-gap solution is to go to settings>manage applications>all>market>clear data and delete updates and then restart the old market which ignores our NC's shortcomings. ;)

Some people reported that resetting the LCD density to 160 and clearing market's data worked but it didn't seem to work for me.
[Nook Color Android Development] joej:
Tried clearing data, deleting updates and restarting the market, my market is still limited...

Can't get uSD card to boot

OK, I am officially an ijit.

No matter what I do, I can't get my card to boot. Using an 8gb Sandisk class 4 card. Used WinImage to burn the 1.3 image, ejected, reinserted the card, and copied the CM7 nightly to the card.

Put in in my NC (previously nootered and got the 1.3 OTA), and it boots normally. Once it boots, the card gets the .android_secure, B&N downloads, LOST.DIR and a few other directories in addition the MLO, u-boot.bin, uImage, and uRamdisk from the installer. I never see the penguin or anything else.

So... Pulled the card, reformatted in Windows (Win7), re-downloaded the i2.3 installer, rewrote the installer image using WinImage, ejected, reinserted in the PC, recopied the CM7 zip file, and tried again. Once again, the NC booted normally.

This card has previously been used to root my NC, had been used as a goldcard for my Inspire, and was used again to root the NC.

What the heck am I doing wrong???
[Nook Color Android Development] archie53:
I ran into a similar problem, you need to use Win32Diskimager, winimage does not seem to work.

Question for others, ran into a problem trying to resize the boot partition on my sd card. What partition tool have you guys had success with?
[Nook Color Android Development] jlmwrite:
Well duh! *That's* why I abandoned WinImage... Thanks!
[Nook Color Android Development] archie53:
Noob question alert. Tried searching but can't find out how to change the LCD density. Thanks in advance.
[Nook Color Android Development] twism50:
There are a couple of apps you could use, both free in the market. LCD Resolution or LCDDensity. I prefer the first.
[Nook Color Android Development] archie53:
Thanks
[Nook Color Android Development] chumpster:
So this may be a noob question. Does this mean that if I have CM7 running of the uSD card right now, I cannot resize my boot partition? I will have to start over if I want to change the boot partition size. Is that correct?
[Nook Color Android Development] DizzyDen:
Correct... Windows programs don't like resizing and moving partitions with the ext formats used on partitions 2 and 3. You can do a backup... setup the SD... resize boot partition... setup CM7 and restore from backup tho.
[Nook Color Android Development] chumpster:
Thanks for your answer. I am planning to move from a 8G card to 16G card, so I was thinking of just writing the image from the 8G to 16G card and then resizing the various partitions.

But it sounds like I might not be able to do that:( I guess I will go with the restore from backup route.
[Nook Color Android Development] kingston73:
Maybe a stupid question but I searched and couldn't find an answer: can you boot into stock 1.3 without removing the SD card running cm7? If so, how?
[Nook Color Android Development] DizzyDen:
boot holding the "n" key... select emmc and normal boot in the menu.
[Nook Color Android Development] tightwad:
I did two nooks the same night, instructions were great! The only changes from the front page would be:

#1. Resizing the boot partition

#2. Google Apps can be installed with the CM7...no need to do it twice.

The hard part now is knowing what else can/needs tweaked!

[Nook Color Android Development] zinjashike:
Need a bit of help here. I used the latest nightly build but was getting lots of media.process and gapps errors. I'm trying to install the stable, but can't figure out the timing for love nor money to install gapps.

I get to the "loading" screen (holding both power and N)

"Loading" leaves screen

Let go of power, re-press power (continue holding N)

Hold power for 5 seconds (continue holding N)

Release power about 3 second into new loading (continue holding N)

Release N after screen flash

Loading shows up for a moment (about a second) towards the right side of center then it begins the cm7 boot. What am I doing wrong here - can anyone point me to a video that shows the process? Or maybe tell me what's causing the errors in the latest build?
[Nook Color Android Development] DizzyDen:
If you haven't flashed the older stable yet... then just power on holding "n" and let go of power... you should see it say "loading boot menu..."
[Nook Color Android Development] zinjashike:
If you meant trying to roll-back from newer to older I tried that, and it left me in a perpetual loading state afterwards.

I really rather stick with the recent releases, but I can't figure out why I'm getting nailed with process.media and framework errors constantly.
[Nook Color Android Development] Marid:
What I did was download the cm nightly, win32, and the generic image thing. I use win32 on the generic image and then i dragged and drop thr cm nightly on to my card. After that, I got the linux penguin and all these words were loaded and then I got the android logo with the skateboard and arrow circle which restarts after every fourth complete rotation. My card us sandisk class 4, 4gb.

Anybody having trouble using the web browser, it takes forever to load a page or doesn't at all. I've tried the stock browser along with Dolphin and Firsfox and all do the same thing.

I had a uSD card go bad (16GB Sandisk) when the nook booted up without it installed and I installed it not knowing it had (it was facedown). Now the card will no longer boot, can't be formatted in Windows, even with SD Formatter.

I used a 2GB Sandisk card that tested well and instead of RC1 I installed the latest nightly...I am getting VERY slow downloads, slow webpages, and lots of Force Closes and "Application not responding" that offers a Force Close or a Wait option.

Not sure if it is the SD card or the build I installed.
[Nook Color Android Development] dcharleyultra:
Did you put your uSD in the nook and boot before dragging the nightly?

I've been having alot of trouble trying to get this to even burn onto a SD card.

So far, i've tried a PNY 8 GB and 16GB card (both class 10), and a Class 4 32 GB sandisk card. I've also tried 2 different laptops with built in SD card readers.... and a external card reader.

The problem i'm having is with WinImage i believe.... I set it up, and when I goto write disk it either makes it to 1% then finishes.... or goes from 1% to 23% then to 44% within seconds of starting, then finishes.

I'm at a complete loss here on what to do..... figured it was a memory card issue, but now I believe its user error. Any advice on what I should be doing would be helpful.

*edit*

Every time I try, it takes up no space on the SD card.... and the files on the card are:

mlo - 15 kb

u-boot.bin - 281 kb

uImage - 2,883 kb

uRamdisk - 1,361 kb

All of these file sizes just seem completely off to me, and of course do not work in the nook.

bootloop?

ok hoping you guys can help. I've tried this many times. I've tried it with nook software 1.2 and 1.3. 1.3 gz image on my desktop as well as in the root drive of my computer. tried both latest stable as well as nightlies 206, 207, 209 and 211. I've tried with the gapps and without. each and every time I do all this It shuts down after installing and I reboot. After reboot I get a green bar the say cyanagen (sp?). Then it goes to the android on the skateboard, the blue circle run around it 4 to 5 times then screen goes black and the blue skateboard android comes back in. it does this over and over and over and is what I'm calling bootloop.

I'm using an ADATA 16g class 10 card.

Am I doing something wrong. I have another card on the way sandisk this time trying to fix this issue?

any help would be greatly appreaciated!
[Nook Color Android Development] DizzyDen:
Try using a Sandisk class 4 uSD.... class 10's tend to have issues with smaller random read/write cycles Android devices tend to use... especially if you're running an AOS on them.
[Nook Color Android Development] cowman4000:
Disregard.
[Nook Color Android Development] Colchiro:
Faster cards are optimized for writing large files, like use in a camera. A class 2 or class 4 SanDisk is rated the best for roms on the sdcard since it has a faster random read speed with small files.

Back to your problem. What build? What version of gApps? What else are you installing (kernel)?
[Nook Color Android Development] lonestarranger:
Can someone confirm this? winimage doesn't work at all? Then why is it out there in the OP? Do we HAVE to use Win32Diskimager???

I'm asking because I followed directions from OP, put the downloaded CM7 nightly ZIP file and it doesn't boot from microSD at all :(
[Nook Color Android Development] archie53:
That is the way it worked for me twice, Win32Diskimager was the only way it worked for me.
