Updated files for CM9/CM10 Bootable SDCard on Nook Tablet (10/27)

I have some suggestions to help you get this going. I have both the 8gb and 16gb NTs working just fine.

You say you are copying the “boot.img” to the CM9 rom zip. If you are talking about “cm9.img” that file goes into the sdcard partition.

Experiences:

First partition, make it 1001 mb. (Or 2001, 3001, etc.) I have expanded this to 16001 on a 32gb, and found by trial and error that this seems to be the largest that it will accept.

What I have found is that not all microSD cards are same. Some cards can be used to boot the Nook tablet and some cannot. I also have a Raspberry Pi, and the same is true there. (If it works in the Pi, it works in the Nook). So, if the card doesn’t work, try another. I don’t know what makes the difference, but I have a SanDisk 8 GB, and that doesn’t boot.

When redoing the card between tries, delete all partitions and create a Fat32 partition and then erase it before creating your partitions to use.

Instead of “system1” name the partition “system”. This helps with the Gapps file later on.

Hope this helps.

  • Copy boot.img/altboot.img, recovery.img, and flashing_boot.img along with u-boot.bin and MLO on to your sdcard.
  • Replace the updater-script inside the rom, *.zip, by drag and drop using winrar/winzip.
  • Flash the rom using recovery.
  • More details are in my other posts.
  • Do this at your own risk!

  • 20120615 New kernel (added support for CCMP, 1200MHz OC), reboot to recovery now boot into recovery (removed cyanoboot from recovery.img) 
  • I’d removed the RC1 part. CM7.2 is final  as of 615 (stable) as Cyanogenmod will now focus on CM9. I will still work on fixing CM7 for NT.
  • 20120618 Display correct mac, can install apps that installed to removable storage.
  • To save battery, try Settings->CyanogenMod settings->Performance->CPU settings ->Max CPU frequency (1008 MHz), Available governors (Performance), Set on boot.
  • If Nook Tablet is not charging (green LED light), just reinsert USB cable (orange LED light)
  • 20120628 Fixed no deep sleep. Set Operating Condition Addendum for CORE OPP voltages. FileManager and RomManager apps are removed. Perfect Viewer, Button Savior, ES File Explorer, Flash Player, and CifsManager apps are included. Included u-boot and MLO from stock 1.4.3. Kernel compiled from 1.4.3 source.
  • If you want to remove those apps, use ES File Explorer (Settings>Root Explorer, Mount File System) and go to /system/app/ to delete them.
  • 20120629 Revert voltages (battery drain). Removed Flash Player (not working properly). Maybe final build unless some crippling bugs shows up.
  • 20120630 Small change to build.prop that fix forced close when using mic. You can also edit the build.prop yourself using ES File Explorer (in Root Explorer setting). Change ‘media.stagefright.enable-record=false’ to ‘media.stagefright.enable-record=true’. Removed some unneeded files.
  • There were 2 goals I wanted to achieve with CM7. I wanted USB host to work with OTG cable so you can use USB devices. Unfortunately I don’t have a powered USB hub to test with my OTG cable. Second, I wanted to test different configurations with kernel and device source. It led to many mistakes, but it was fun fixing it. I think I am done with CM7 and moving on to compiling and testing CM9 permanent.

How to Guide: Dual-boot (CM7/CM9) SDCard for Nook Tablet (5/28)

Mockup


Notes:

  • UPDATED GUIDES: How to Guide: Bootable (CM7/CM9/CM10) SDCard for Nook Tablet
  • DO NOT SELL PREBUILT SDCARD WITH ROM
  • You need to have a SDCard 4GB or bigger. The default steps are for 4GB sdcard.
  • For sdcard bigger than 4GB, you need to make adjustments.
  • Data partition stores your apps, so you want at least 1GB.
  • System partition stores your system files and apps, 350MB – 400MB is all you need.
  • SDCard partition stores your boot files and misc. files so the larger the better.
  • Need help? http://forum.xda-developers.com/showthread.php?t=1545766
  • If done correctly, your Nook Tablet should boot to fattire’s Cyanoboot, if not, nothing.
  • I’ve made changes so it’s easier to make just a cm9 bootable sdcard
  • If you are stuck at the two androids when booting CM7 for over a minute, boot into CWM Recovery and wipe cache partition.
  • Added file for CM9 Alpha 0.04
  • If you can’t get wifi working in CM7, it mean you used the wrong cm7.img.
  • New Boot Menu with altboot1 – 3. They are for partitions system3 – 5/data3 – 5 if you want quintuple boot.
  • Not all sdcard brands are made equal. I always recommend SanDisk due to fast small block random write.
  • Learn more about it here, http://forum.xda-developers.com/showthread.php?t=1005633
  • Added file for CM9 Alpha 0.05/0.05.1. You can mount both sdcard and emmc now.

Nook Tablet CM7.2 RC1 4-25

Background ^

The process of developing for the Nook Tablet was a slow one. The Kindle Fire had a head start in development because the device was not lock, which attracted developers. CM7 and CM9 came out on Kindle Fire ahead of Nook Tablet. At that time, the Nook Tablet had a locked device and lacks developers. Nook Tablet had root access created by Indirect, but the device was still locked. There were attempts to bypass the locked boot loader on Nook Tablet by AdamOutler and hkvc with moderate success. It was not until later that bauwks found a hole in the Nook Tablet source by creating a second bootloader referred to as second u-boot or irboot. After the second u-boot hole was found, we had CM7 ported to Nook Tablet by Team-B, consist of CelticWebSolutions and Goncezilla. Ubuntu popped up on Nook Tablet by AdamOutler. CM9 was at infant stage by nemith and fattire. Nemith later dropped developing on the Nook Tablet due to kernel constraint and personal stuffs. Kernel 3.x was needed for CM9 to support all the goodies like hardware acceleration and decoding. Along came chrmhoffmann and Kuzma30 helping porting kernel 3.x. Chrmhoffmann backported some 3.x features to Nook Tablet current kernel, 2.6.35 and released a working CM9. Kernel 3.x is still being developed and things are shaping well.

For the past couple of months, I have been learning how to compile CM7 for the Nook Tablet. Without device and vendor source, I had to borrow from the next best thing, Kindle Fire. Kindle Fire and Nook Tablet are not that much different in term of hardware specs. Besides the obvious different in storage space and ram until Barnes and Noble decided to release an 8 GB version of the Nook Tablet, there were differences in external sdcard slot, and microphone. The Nook Tablet and Kindle Fire shared similar Wi-Fi chip, audio chip, CPU, GPU and kernel base. This makes developing between devices easy. I have taken available device and vendor source from WhistleStop and JackpotCalvin, Kindle Fire developers, and I tried to create my own device and vendor source to compile CM7 for the Nook Tablet. Along the way, I used other available sources from Nook Tablet, Droid Bionic, and LG P920 for references. It was a success.
