Try to boot an initrd and mount the usb manually, does it work?

Did you add the correct dev file as "root=/dev/sdX" in the loader script?

I'm not 100% sure but you should omit the '"'s.

I tried it without the '"'s but it still isn't working. The panic screen is a bit different though, I also tried upping the rootdelay to 10, but it doesn't work. p.s. How should I put the rootfs on the flash drive, I tried 'tar -xvf ../xconfig_latest.tar.xz' but it gave a bunch of errors about not being able to make links.

Howto: Extract tar files onto a ext4 partition:
Code: [Select]
sudo -i
mkfs.ext4 /dev/sdbX
mount /dev/sdbX /mnt
tar -xvf xconfig_latest.tar.xz -C /mnt
umount /mnt
exit

I did all of that except for the mkfs.ext4 /dev/sdbX What does that line do?

That creates an ext4 filesystem.

My computer (Debian) doesn't have the mkfs.ext4 command, was the period supposed to be a space? It doesn't have mkfs either. Also, what is the difference between the dtb and non dtb kernel?


EDIT: never mind, forgot to run it as root

Still giving me a kernel panic, but I can boot using the initrd and chroot into the flash drive, however when I try to startx, it complains about /dev/tty0 not existing

I finally got it working :w00t: I had to add init=/sbin/init to the kernel cmdline.

Great to hear you got it to boot! But init=/sbin/init shouldn't be needed as that's the default, weird.

Is there any way to gcc/g++ onto the flash drive/calculator so I can write/compile programs on the calc?
