Yes, I am mounting it that way. I can see the files on the drive, but the programs don't work.

Code: [Select]
# /mnt/usb/usr/bin/nano
/mnt/usb/usr/bin/nano: can't resolve symbol 'stat64'
# /mnt/usb/usr/bin/startx
/mnt/usb/usr/bin/startx: line 202: /usr/bin/mcookie: not found
Couldn't create cookie

Yes that happened to me when I mounted it. What device file did you use?

You can try to
Code: [Select]
mount --bind /dev /mnt/dev
mount --bind /sys /mnt/sys
mount --bind /proc /mnt/proc
mount -t devpts none /mnt/dev/pts
chroot /mnt
startx

I'm using /dev/sda. (I hope you don't notice that I have no idea what a device file is :))

That seems to mount the drive as read-only filesystem. X does not work, but nano and mplayer do.

(Yes, I'm too lazy to copy your formatting :P)
/dev/sda is correct. (If it's on your calculator. On your PC it should be /dev/sdb or /dev/sdc)

My commands don't mount the drive at all, they require it mounted at /mnt.
But why read-only? Could you show us the messages showing up?
What's the output of fsck.ext4 <drive>(if fsck is not on your calc, try it on your pc)?

On PC it seems to be read-only too.
Code: [Select]
user@ixtremeM5850b:~/Downloads$ fsck.ext4 /dev/sdh
e2fsck 1.42 (29-Nov-2011)
fsck.ext4: Permission denied while trying to open /dev/sdh
You must have r/w access to the filesystem or be root
user@ixtremeM5850b:~/Downloads$ sudo fsck.ext4 /dev/sdh
e2fsck 1.42 (29-Nov-2011)
Filesystem did not have a UUID; generating one.

/dev/sdh contains a file system with errors, check forced.
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information
/dev/sdh: 3320/3784 files (0.5% non-contiguous), 70671/83896 blocks
I reformatted it to make sure everything is right, but still the same result.

It should be r/w mountable by now.

Are you able to boot directly to the flash drive?

Yes! This works now too. Thanks again.

Now to figure out how Bluetooth and tethering works...

I got debian working!
I used multistrap to get the rootfs, then my Raspberry pi to set it up the rest of the way (like running dpkg)

Good :)

In fact, it can be even simpler than that: the qemu-user-static Debian package contains everything needed to finish the creation of the rootfs, without delegating the second stage of debootstrap / multistrap to a physical ARM board :)

Code: [Select]
# Make sure we have the appropriate packages.
apt-get install debootstrap multistrap binfmt-support
# This package ought to register the appropriate definitions for binfmt-support
apt-get install qemu-user-static
# Load binfmt support
modprobe binfmt_misc
# Start a debootstrap that will fail when trying to install the packages
mkdir $DEST_DIR
cd $DEST_DIR
debootstrap --verbose --arch=armel sid . http://ftp.fr.debian.org/debian/
# Fix it. ln assumes the programs are on the same partition, use cp instead if they aren't.
ln /usr/bin/qemu-arm-static ./usr/bin/qemu-arm-static
# Start debootstrap again, and while at it, we can add some packages into the mix :)
debootstrap --verbose --arch=armel --include=locales,build-essential sid . http://ftp.fr.debian.org/debian/

Glad to see more distros working on the Nspire :)

Does this one work on the CX too?
