I followed klausef steps and made a backup img then copied over the files that we so kindly shared and my simple touch is now running off the sd card!!

I havent seen any lag like klausef but I have changed the background and added some app shortcuts to the home screen and when I take the card out it is different so I know it is running off the sd card.

Thanks klausef for all your work and helping me with this. It is great I cant wait to see how far it goes.

Please look this thread over and consider moving it back to the development forum; it has clearly evolved into a development thread.

I am loving my bootable sd card and having been messing around with it most of the day.

One thing though is there a way to partition the sd card so the nook will see the partition as the sd card? Right now when i try to download something it doesnt see an sd card.

Ha! Such a simple fix, yet works brilliantly. I was able to transplant my rooted system to an SD card and then run it on an out-of-the-box Nook Touch. There's no obvious slowdown

Yeah I am loving my bootable sd card but still cant figure out how to partition the sd card so part of it will show up as an sd card to the nook. Also I have been trying to change the booting.pgm to a different boot image but just copying and pasting over another pgm is not working for me.

Oh, so there isn't; `free` returns 0 bytes dedicated to swap. I need to source my comments a bit more thoroughly

Hi, unfortunately I do not have sdcard that would let me to fit whole system but let me know it following would work (only assumptions baseod on my observations of the system:

1. Are you able to create additional FAT32 partition on sdcard after flashing the nook image? I believe this should be possible but I am not sure whether the nook would still be able to boot and work properly.

2. Are you able to mount the new partition in nook?

3. If yes, mount setting for sdcard seems to be stored in /system/etc/vold.conf
Code:
## vold configuration file for zoom2
# modified for encore

volume_sdcard {
    ## This is the direct uevent device path to the SD slot on the device
    media_path     /devices/platform/mmci-omap-hs.1/mmc_host/mmc0
    partition	   6
    media_type     mmc
    ##mount_point    /sdcard
    mount_point    /media
    ums_path       /devices/platform/usb_mass_storage/lun0
}

volume_sdcard2 {
    ## Currently points to internal eMMC, assumes eMMC is formatted as FAT32
    media_path     /devices/platform/mmci-omap-hs.0/mmc_host/mmc1
    media_type     mmc
    ##mount_point    /media
    mount_point    /sdcard
    ums_path       /devices/platform/usb_mass_storage/lun1
}
Thats because the mounted sdcard is mounted as
Code:
/dev/block//vold/179:17 /sdcard vfat rw,dirsync,nosuid,nodev,noexec,uid=1000,gid=1015,fmask=0702,dmask=0702,allow_utime=0020,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0
Maybe it would be possible to update vold.conf with correct patch to new partition and let him mount it.

Wow, this seems to have gone really far. Awesome! I just got a new Sandisk 16GB uSD, and my Nook has a broken screen, so if anyone wants to send me experimental kernels or anything that might possibly brick the thing entirely for the sake of experimentation, I'd be happy to sacrifice my already useless Nook. Only the top 1/4 of the screen actually updates, but I can use ADB to get a look at the screen. Now time to try this for myself...

Have you tried editing /system/build.prop?

Code:
ro.sf.widthpixels=600
ro.sf.heightpixels=800
Maybe changing the height to 200 pixels would get you a functioning 1/4 screen?
