[Barnes & Noble Nook Tablet] meghd00t:
I just booted this on my 16GB nook and a few comments

in adb shell

dmesg shows

<4>Ignoring tag cmdline (using the default kernel command line)

but in the new 1.4.2 update the whole point was that MLO and u-boot would determine the correct RAM and pass that in the kernel cmdline so I think this needs some investigation.

next I cannot see the sd card in twrp only the internal emmc.

these paths have changed from CM7.2 so the recovery.fstab and vold.conf will have to be updated

also

~ # cat /etc/fstab

/dev/block/mmcblk1p1 /sdc vfat rw
/dev/block/mmcblk0p10 /emmc vfat rw
/dev/block/mmcblk1p2 /sd-ext rw

this is missing /dev/block/mmcblk1p1 /sdcard

~ # grep mount *.rc
init.rc: mount /tmp /tmp tmpfs
~ # grep sdc *.rc
init.rc: export EXTERNAL_STORAGE /sdcard
init.rc: mkdir /sdcard

/dev/block/mmcblk0p10 /emmc vfat rw
/dev/block/mmcblk1p2 /sd-ext rw

/etc # mount /sdc
/etc # df

/dev/block/mmcblk1p1 31150704 7921504 23229200 25% /sdc

so it is able to mount the sdcard on /sdc

when I did less on /init.rc it has dos line endings it needs a dos2unix

and finally there is a kernel oops in the dmesg
