[IDEA] Boot XBian from USB

[CurlyMo]

I only noticed a big speed decrease so results differ.

Really?
I came from a Transcend Class 10 card and the USB 2.0 is really faster. Especially when working in the shell and doing some compiling for example.
But as I said, the by far biggest advantage is to get rid of the filesystem corruption even with overclocking (arm_freq=1100;core_freq=500;sdram_freq=500).

Thanks all. What should the USB be formatted as?

Edit: This is what I got:
xbian@xbian ~ $ dd if=/dev/mmcblk0p2 of=/dev/sda2
dd: opening `/dev/mmcblk0p2': Permission denied
xbian@xbian ~ $ sudo dd if=/dev/mmcblk0p2 of=/dev/sda2
[sudo] password for xbian:
dd: writing to `/dev/sda2': No space left on device
20481+0 records in
20480+0 records out

Can you post:

Code:

fdisk -l

[rendez2k]

Do you mean type that in putty? I get:

xbian@xbian ~ $ fdisk -l
-bash: fdisk: command not found

Code:

sudo dd if=/dev/mmcblk0 of=/dev/sda

[rendez2k]

Thanks - seems to be doing something.....

Does that mean I need to change /dev/mmcblk0p2 to /dev/sda2 to sda? Does it depend on port?

[CurlyMo]

No, keep the /dev/sda2

[rendez2k]

Hmmm, sticks flashing but its taking ages! Stick in FAT32 format. Command line not updating after command.

If u use something like "bs=1M" it'll be faster.

[rendez2k]

Sorry, whats bs=1M, a command?

U use dd, it not fat32 anymore

[rendez2k]

Well, for me, its slower. Using a Class 4 SD Card and a Intergral USB 3 stick, it seems noticeably slower booting up. Trying a class 10 card now without USB.
