Updated 2nduboot based on 1.4.2 for 8GB NT models (verified)

---

I merged the latest B&N 1.4.2 code into my 2nduboot git repository on github: https://github.com/bauwks/Nook-Tablet

It still compiles and works on my 16GB NT and others have have successfully booted the 8GB NT model.

The instructions for building are the same as before:
cd distro/u-boot
PATH=/usr/local/arm-2010q1/bin:$PATH
make nt2ndboot_sd_config
make
./tools/build_nt_2ndboot_img.py -o test.img u-boot.bin
cp test.img /media/boot/flashing_boot.img

For those of you that wish to try it without messy compilers, this zip file (http://dl.dropbox.com/u/40331061/bauwks-boot-1.4.2.zip) contains:

• MLO from 1.4.2
• u-boot.bin from 1.4.2
• flashing_boot.img <- the 2nd uboot

Unzip it to the root directory on an SD card, drop in a boot.img you want to test and go. If you see the box then it's booting off the SD card and should then load your boot.img.

Great job bauwks!

Someone with an 8 gig model please test this. If it works, I can begin working on a resurrection solution for the NT 8gig.

FWIW "Cyanoboot" (w/menu and all that) has been tested and works w/512 model as well.. stay tuned.

Incidentally, my tester did seem to indicate that sd card boots need to be tethered. FWIW

so going off of what i have read heres what ive gotten so far.
format the sd card to fat32 and make sure the flags for boot and lba are on.
transfer the files to the root directory of the card (im assuming this doesnt mean try to write any of the image files to the card).
put the card in the nook.
press the power button and it should boot from the sd card.
this is everything that i have done and the device wont power on while the card is in the slot but i can take it out and it works fine.
am i doing something wrong?
anyone else have this issue?
EDIT: booted after i changed the partition size to 50 mb, but it didnt change or add anything.

just for clarification. Even if this allows boot and root from SD card, people should still not be using this new found access to flash roms designed for the 16gb on the 8gb? I say this because, last I read the acclaim update bricked the 8gb tablet.

that could be mine, but the tech at b&n says it's hardware problem so I'm not too sure. the flash was going well half way and when I stepped away for a couple minutes and came back to find it bricked.

Actually, I believe if the kernel is 1.4.2, there should be no problems and CM for the nook tab should have 1.4.2, we would need gonce to come in and verify though.

As long as the bootloader and kernel are based on the latest kernels and such there shouldn't be a reason that both devices can't run the same roms. The issue with the acclaim update is that it flashes the bootloader/kernel stuff from 1.4.0 which doesn't take into account the variances between both devices. Since the 1.4.0 bootloader doesn't know how to take into account the 512 memory you get a bricked device. If it were possible to create an acclaim update with the newest 1.4.2 bootloader/kernel and a 1.4.0 file system except for a couple of possible driver related changes the 1.4.0 file system would work fine on the device.

However, as long as we stick to the same guidelines that BN will, any rom we release should work just as effectively on both devices. This is because BN has designed the latest BNOS to run on both devices so that they only have to release one update file in the future as opposed to support for two devices with so few differences between them. As long as we take into consideration both devices by using the latest bootloader/kernel sources, it should work on both devices without a hitch.

I am sorry to sound so dumb but I came to the party late. (Just bought the 8gb NT yesterday.)
I did create the 50meg partition and loaded the files to it. It boots to the box but I am uncertain of where to go from here. I have tried to find related threads but I have not been successful.
Please be kind.. ;)

So far this is the only thing that has been release for the 8gig. I haven't seen any CWM or 1.4.2 ROMs yet. I know that they are currently working on CM7 for 8gig and an Ubuntu recovery.
