[Q] Cyanoboot Loading - Nook Color Q&A, Help & Troubleshooting

I have CM7 installed on eMMC, and CM10 installed on an SD Card.
I was wondering how do I make the eMMC automatically boot first instead of the SD Card?
R800i. 'Nuff said.

There is a app in the play store from Dal "Nook Tweaks" that will allow you to set the boot order. And a collection of other things as well.

Might be complicated...
I have tried to get the Nook Tweaks app to change boot order in evry installation I've used, but with no luck. I do know that the first file read by the nook to boot is the uboot.bin in the first sdcard partition. If you could somehow recode that (make a backup first!) in the Nook's machine language, you could make it do just about whatever you want. Or you could ask one of the big Nookie devs to do it (fattire, eyeballer, krylon360, etc)
Good luck!
PS If you get that working, could you PM me with a link to it? Thanks.

You don't need to do any recoding of u-boot.bin. If you look at fattire's thread on CyanoBoot, (which is a modified u-boot.bin) you will learn how to put two files in the /rom partition to tell u-boot.bin how to boot. That is what Nook Tweaks does for you automatically.

[Q] CM7 SD Boot - Can you expand EXT4

I've had a lot of success creating a bootable CM7 using the size agnostic preparation instructions. (Here) I want to keep the Nook at stock, for a variety of reasons. Anyway, I created a very nice installation on a 16gb uSD card and did a lot of work setting up LP+ and my hundred-odd android apps. (I also have an Evo 4G). I was fortunate enough to get a 32gb uSD at a great price and want to move my installation over to that. The most successful by making an image with the Win32DriveImage and flashing that back to the 32gb uSD card, which leaves a large area of un-partitioned space. I've tried a couple downloaded tools but have been unsuccessful. Is there a command I can use in Terminal Emulator to to do that? I know I can use the agnostic procedure to start from scratch, but I'd really hate to do that.
The only thing that would make starting over is if someone can point me to instructions that would allow me to have an installation that boots from uSD and has fully functional CWR and Rom Manager. I love how it works on my EVO to download and install updates with a couple clicks. (Everything I've tried there seems to mess with the core Nook).
Thanks a lot!

Use Minitool Partition Wizard, or another windows partition manager to expand the last storage partition.

Thanks for the suggestion. I tried a few partition managers and run into the same problem including with MiniTool. It will start the process of expanding or copying and expanding in one step, but it will eventually say "file system error" just before it finishes. It suggests repairing the file system, but none of the tools can do this with the ext4 partition. Still trying though. Gonna give the Acronis partition manager a whirl.

You can edit partitions with fdisk from the terminal emulator. I suggest googling, it's a pretty old school tool and isn't very friendly. You should easily be able to resize your "sd" partition with that. Actually more accurately you should be able to delete that last partition and then create a bigger one in it's place. won't keep your data, but you can just copy it over to your computer and resize, then copy back.
Another option would be gparted which comes with basically every live linux cd ever. That one can actually do true resizes and should handle ext4 partitions easily (it is a linux file system after all)

You don't need to start over. Get a new uboot.bin for your cards boot partition from here.
Then get the clockwordmod kernel and ramdisk from the zip at the end of this post. Put the uImage and uRamdisk on the sd card as uAltImg and uAltRam.
Now when you choose sd:alternate from the boot menu it will boot you into clockwork.
Thank you so much. I think that will do the trick.

OK. All is well and the dual-boot solution is super-convenient. But I'm a little perplexed as to how to work with CWM in this environment. Ideally I'd like this to work just as it does on my EVO, Rom Manager lets me know there is a new version, I select it, it downloads asks if an want Gapps and backup (yes please) then it does its thing. Maybe that is way too much to ask. If so, then the main things I need to know are how to instal an updated build that I download separately? Do I just copy it to the root of the boot partition.
Sorry for being such a n00b with the nook. Its funny but I'm much more confident messing with my phone, which if bricked, is pretty catastrophic. (LOL)
The instructions for updating CM7 for the agnostic build is in the OP's post for that build.
"How to update to a new build:
put the new build you want to try on the first partition. (the name must be update-cm-*.zip or cm_encore_full*.zip or just update-*.zip)
Boot from the SDcard in the recovery mode (see above) and the new snapshot would be installed.
The partition layout would be preserved, filesystems are NOT reformatted, so your data should be safe."
Also, Easeus Partition Manager is supposed to be able to resize partitions w/o destroying data. YMMV, of course. I used it to extend ext 4 but prior to putting anything there.
Didn't have any luck with easus either, but ended up using a gparted boot which worked great. Normally I would use recovery nandroid to backup the rom before installing the updated, but when I did that by booting into alternate, I ended up backing up the nook rom to the root partition, so I think the safest thing to do is to use win32diskmanager to image the entire sd card.

So, just to make absolutely sure, if I already have CM7 installed on an SD card, which I've been using as a daily driver, installing apps, downloading Kindle books, PDFs, and the like, but I want to put CWMR onto the SD card, the steps you outlined should be OK?
NOTE: I know, I know, if I'm confused I probably shouldn't be screwing around with things...But the size-agnostic SD CM7 method was so bloodless that I thought the other stuff would be pretty easy to do. For whatever reason, adding stuff like the OC kernel and CWMR has been a little confusing.

[Q] Accessing CM7 SDcard while using standard Nook firmware

Just got my NC last week and thanks to this site have successfully been running CM7 (latest stable version) on a 16GB Sandisk class 4 card. I have put a few movies into a folder on the SDcard in a folder I created /MyFiles/videos. CM7 automatically found them and they playback fine.
For kicks, I booted into the emmc mode last night (running 1.3). I can browse my SDcard and see the /MyFiles/videos folder, but no files show up. Shouldn't I be able to see these files while booting with the standard Nook mode?

What a SD CM7 sees as the "sdcard" is partition 4 on the card... stock does not see this partition... what stock is seeing is the first (or "boot") partition on the card.

Thanks for the reply. That's weird because I don't think I created the path /MyFiles/videos anywhere on the first partition but I was seeing that folder. Looks like my something is messed up though as I can't get my CM7 to even boot now. It just sits there spinning at the CM7 logo. Any ideas?
Another update. I put the SD card in a USB reader and put it in my Linux machine. It sees all 4 partitions and my files are still where I thought they were. The CM7 SDCARD partition has a /MyFiles/Videos with my movies in it and the /boot partition has a /My Files/Videos folder that is empty. So all of that explains why I couldn't see my files when booted into standard Nook mode, but I still can't boot into CM7. Please help.
Why did you created /My Files/Videos folder in the /boot partition?
First step would be delete them off.

I don't even remember doing that, but it is possible that I did. Deleting those files didn't fix it.
I just remembered something else I did. When I was trying to boot into Nook mode, I forgot to hold in the nook key so it started booting into CM7. When it did that I held in the power button to turn it back off. That is probably what horked up my CM7.
Do you have a clean backup? Try that?
Worst case, redo your uSD

Unfortunately, I'm so new to this I haven't even looked into how to back it up. I downloaded the free version of Titanium backup but hadn't messed around with it yet.
I used Evergreen's method for installing with the size agnostic image. Is there a way to reinstall without wiping the uSD card and starting from scratch?

Try just putting the same nightly or stable build you used before on the boot partition and boot into verygreen's recovery mode.

Tried that and it didn't work either. I've given up and just started over from scratch. Will have to look into a backup procedure. Thanks everyone for the suggestions.
Honestly, I didn't even know or remember how to make a copy if running off uSD.
Clone it, maybe?
Using the auto-recovery method on the SD card then the file must be called update-gb-*.zip for it to install it. It is also aware of files called gapps-gb-*.zip. Any other files will be ignored.
Providing the file is named like that then you should see it install it when powered up with N key pressed and recovery selected.

I just meant the recovery mechanism that comes with the SD boot. Powering up with N key on and selecting recovery boots into a mode where it will just install the zips I mentioned and not a full menu driven recovery mode where you can reformat partitions, select which zips to install etc.
He asked how to make a backup, not how to install or update.

[Q] Dual Boot from emmc and from internal storage

It's not difficult. Just follow these threads below.
First install CM7 to emmc per this thread:
http://forum.xda-developers.com/showthread.php?p=12797652
Then install CM9 to SD per this thread (just substitute CM9 for CM7 in the instructions):
http://forum.xda-developers.com/showthread.php?p=12240928
Also you need to use my updated generic image file instead of the one in the link above. Get it here:
http://forum.xda-developers.com/showthread.php?p=23153010
If you want to use both systems with the same SD card so you don't have to swap cards all the time, follow these instructions:
After you have installed both of these systems, go to CM7 and using root explorer, edit the file vold.fstab in /etc. There will be a line there that includes 'sdcard auto' (without the quote). Change that to 'sdcard 4'. Save and reboot. Now both CM7 and CM9 will share the same media sdcard space. No need to swap cards between systems.
Also to determine which system boots, hold the n key while nothing and a boot menu will come up. Use it to select which system you want to boot to.

Why?
BTW, emmc and internal storage are the same thing.
edit: There are some really old threads that tell you how to repartition the nook so that you can have two systems on emmc. But that is no longer recommended due to many issues, including updating is difficult and repartitioning is risky.
edit2: If you are thinking you can install a system to the media partition of emmc ("internal storage"), it's not possible. The only way to get two systems internally (ie., without using an SD) is to repartition. The existing media partition is deleted and new system partitions are created to accommodate the new system files and then a new smaller media partition is recreated. But that is a very non-standard installation and most update- zips will not work with that setup. You have to use specially modified versions.

Look at my edit2 above. That "internal storage" shown is just a partition of emmc (/data, which is part of emmc where your system data and apps are stored). And other systems cannot be installed there.
Why are you against SD installs?
edit: Just a little educating, emmc means Embedded MultiMedia Card. It is where everything is stored internally. It is partitioned into several partitions, /system, /data, /cache, and others. It creates a media partition to store your media and it calls that "emmc" on that picture you posted. and it calls the /data partition "internal storage". Very confusing for noobs.

No, see my edit above.
Edit: But you can change the size of each by repartitioning. The old nooks came with a 1GB /data and a 5GB /media. The newer nooks come with 5GB /data and 1GB /media. Looking at your picture you have the old nook.

That is if you install a usb drive by attaching a special adapter and plugging in a usb flash drive.
If you want both CM9 and CM7, I highly recommend the scheme I listed in my first reply. It's what I use and it works great.

After thinking about it, I would recommend reversing which is on emmc and which on SD. You will not be updating CM7 very often and likely updating CM9 a lot. It is easier to update emmc, so I would put CM9 on emmc and CM7 on SD.

[Q] Can I have partitions that can be accessed from both NC Stock and CM7 on SD card?

Hi everyone!
I just got CM7 (latest stable release) installed on on external sdhc card. I have wifi issues with CM7 (and looking around the forums tells me that CM7 can be finicky with certain routers) so I would love to be able to use Nook's stock ROM (4.1.4) when I am having issues.
But, when I am on NC ROM, I don't see anything except the small boot partition on the SD and when I am on CM7, I don't get access to this boot partition. I am wondering if there is a way to either create another partition or make the currently existing partitions accessible on both ROMS so that I can share data between them.
I am a n00b without any Android experience so thanks in advance for your patient responses.

If whatever you have on emmc is rooted, you can manually edit it. If you have unrooted stock, then you need to flash the zip since without root you cannot edit those files manually. And I did mean item B3. Each item is a different topic, they are not steps. One topic does not depend on another. Just do B3 and no others if you want.
Yes, item B3. My mistake...
I should be able to do flash the zip from my current CM7 SD card's boot partition, shouldn't I?
So I put the update-stockemmc-vold-fstab-modified-for-partition4.zip file in the boot partition of the SD card, rebooted to Recovery mode and then booted to NC's stock ROM. NC is still using the tiny boot partition on the SD card as my external storage instead of the much larger CM7 partition. This was the same partition that was under 'My Files / Memory card' before I flashed so nothing has changed. I did this twice to double-check.
Am I doing this wrong?

Yes you are doing it wrong. You need to flash that file with a CWM card, not put in the boot partition of your SD. And since you did that, you need to re-flash your latest ROM on SD to correct your mistake. (I will edit my instructions to make it a little clearer that you use CWM to flash that file.)
I got NC stock ROM to see my SD card partition by following item A10. That is most excellent and thanks again!
Unfortunately, I no longer see the boot partition when I attach NC to my computer whether NC is running off stock ROM or CM7. My guess is that this is due to my failed attempt to flash from my CM7 SD card yesterday. Am I right?
I thought I could reverse that by copying the update-stockemmc-vold-fstab-return-to-stock.zip file to CM7's boot (and then booting to the recovery mode) but that seemed to have nothing.
If I understand your previous message correctly, I should re-do my entire SD card but... I have already spent a few hours downloading and customizing the Android apps. Is there a way to preserve all that before Win32diskimager destroys the contents of the SD card?
Is there a way to manually mount the /etc folder from a unix prompt and alter the file?
Does it even matter if I don't see boot while I attach NC to a computer? Are there any caveats to 'let it be'?
Questions, questions and more questions...
That leads me to the obvious question, is there a book that explains Android to someone who is not interested in programming it but wants to understand the architecture and design of the OS (and custom ROMs)?
Thanks for being patient with all these n00b questions.

You do not need or want to re-set up the whole SD installation. Just put the same CM7 zip file back in the boot partition and boot to SD recovery. It will put the correct vold.fstab back on the SD. You will not lose any settings or apps you have already set up. (And putting the return to stock zip there was also the wrong thing to do. The vold.fstab for stock and CM7 are different. But don't worry, it will fix that too.)
You are not supposed to see the boot partition on the PC when you plug the nook in with the cable. You are only supposed to see 'emmc' and 'sdcard'. Under the original setup, your stock system thought the boot partition was 'sdcard' and that was why you saw it on your PC. Since you modified stock to see partition 4 as 'sdcard', partition 4 is what the PC sees, not the boot partition.
Most people have to physically take the card out of the nook and put it in the PC to see the boot partition on the PC. If you don't want to do that, use my script in item B4. But since you are on CM7, you will not be adding many things to the boot partition to install with SD recovery in the future. So it is probably best to leave things be.
And I don't know of any books to help you.

That is excellent news!
A bit of playing around with Astro tells me that I was wrong about seeing the 'CM7 SDCARD' partition when I was on CM7 ROM. I am only seeing the boot. Anyway, I am going to flash the CM7 ROM again and I am hoping it would fix everything.
Also, yes, I can see the boot partition when I put the SD card directly on my computer but I was also able to see it when I hooked up the NC to my computer via USB before I did my unintended tweaks but... I'll survive.
I'll be back after I flash. (Famous last words??)
Mission accomplished!
Thanks again for all your help.
For future reference after you alter stock's fstab... all you have to do is:
mkdir /sdcard/boot (only have to do this one time)
mount /dev/block/mmcblk1p1 /sdcard/boot (do this every time you want to put something on the boot partition)
put anything you want on boot partition in /sdcard/boot

Yes, there is one big advantage to using that method. I think it allows the boot partition to be seen not only on the nook, but also on the PC when you plug in the usb.

We could probably come up with a symlink to /dev/block/mmcblk1p1 to /sdcard/boot and avoid having to mount it everytime as well.

Thank you Dizz, your suggestion got me to thinking and I was able to come up with an init.d bash script that does the trick. I just temporarily mounted sdcard and created the sdcard/boot directory and the mounted the boot partition to it, then unmounted sdcard so it could be mounted again by the system later in the boot sequence.
The only problem is now sdcard will not mount on the PC using UMS mass storage. Must be because of having a second mount within the mount. But it does mount with MTP. But that may be acceptable. I will test some more, including using Goo Manager tomorrow.
EDIT (6-21): Goo Manager works. But I think I have figured out why sdcard is not mounting in UMS. Once it is mounted in my script and the boot partition mounted under it, it cannot be unmounted. And since it cannot be unmounted, it cannot be mounted later by the system as vold. If it cannot be mounted as vold, it does not show in UMS. For now I think I will leave it as I have it in Rev 2 of my script (symlinking to the root directory with full r/w permissions). If people want to see the boot partition on the PC, just use my modified for CM9 NookColorUMS available in my tips thread.

Help!
When CM7 is running, my computer is no longer mounting any of the partitions when I connect NC to my computer via the USB cable.
If the NC stock ROM is running, my computer mounts all three partitions (MyNook..., boot and CM7SDcard) but calibre is not recognizing the external partitions for transfers.
Further, when I boot to my NC stock ROM, I am no longer seeing my SD card's contents in the NC's library.
This may have something to do with the fact that NC stock ROM seemed to have updated itself to 4.1.3.
Should I re-run the scripts again or am I missing something else?
When it was updated to 1.4.3, you lost the emmc mods. Just re-flash my zip with the CWM SD. You may have lost CWM on emmc too.
On CM7, you have to select the turn on storage button after you plug it in. It is not automatic like stock. Pull up the notification area and touch the turn on button.
Darn, I forgot about that 'USB' option under notifications. Enabling it allows me to find the partitions. I will run your scripts again when I find a spare mUSB card.
Thanks again for your help!

[Q] Clarification On Making CM-10 Card

I have read multiple tutorials on making the card (mostly C-M 7) and there seems to be some differences. Some say to expand the boot partition and some don't. Which is it? If you have to grow it to how do you do it if you have only Linux? Gparted can't grow FAT.. I tried but 3 different versions errored out.
Second is do you copy the gaps.zip and C10.1.zip to the unused portion of the SD that is there after the image file is written to the SD card or the boot partition that is created.
One tutorial said I should unmount the card before writing the image. None of the others did.
Any help for a newbie appreciated.

Use my NC guide for installing CM10 to SD linked in my signature. You do not expand the boot partition, I have made it big enough, use the rev8b version. Copy the CM files directly to the boot partition.

When I attempt to copy CM.10.1.3.2 I get disk full. Tried as User and root.
Looking at the partition in Gparted I get Size=117.63 MB Used 9.73 MB Unused 107.90 MB so it doesn't seem to be full.. The image I used was Android/generic-sdcard-v1.3.img

I told you to use my rev8b from my thread. That old 1.3 will not work on the new CM zips.

Sorry. I did get that from a link in your thread. I will have to go back and look for the correct link. Thanks for your patience.
Got it. Thanks for all the help. Now if the Post Office finally delivers the Nook I bought I can test it.
