Setting root with UUID in cmdline.txt

[Patatra]

Hi,

As I'm using different USB keys on the Pi, I would like to indicate the root disk in cmdline.txt using the UUID of the USB key that share the system but it doesn't work. I got the UUID using blkid.
It doesn't boot, it stucks on the Raspberry we first see and nothing else, no boot message, no error, nothing.

What am I doing wrong?

$this->bbcode_second_pass_code('', 'smsc95xx.turbo_mode=N dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 root=UUID=7a6820e4-9dd6-4799-9570-4b3852f4aea4 rootfstype=ext4 elevator=noop rootwait')

I've try with <UUID>, "UUID", UUID but it's the same.

Thanks.

I searched the raspberry pi forum for UUID, 85 matches
I searched within those 85 matches for rootfstype, and nothing there, I doubt this would ever work

I've made that search too, didn't find anything either.
But I've seen on OpenElec's wiki :

$this->bbcode_second_pass_quote('', 'N')ext we create a “cmdline.txt” file that contains bootloader parameters:Lp

$this->bbcode_second_pass_quote('', 'e')cho "boot=/dev/mmcblk0p1 disk=/dev/mmcblk0p2 ssh quiet" | sudo tee /media/System/cmdline.txt

You need an united for label to work

[Patatra]

Sorry but what do you mean by "an united"? English isn't my native language

Damn you auto correct.

An initrd

Ok! So it wasn't my bad english!

I'll try that. Do I need special stuff in the initrd for label to work?
I've made one with just $this->bbcode_second_pass_code('', ' HOOKS="base udev autodetect block filesystems"
') and a gzip compression, will it be enough?

Now, I just have to set initrd= in cmdline.txt?
I don't have access to the Pi right now so can't test.

Thanks.

I don't think it's so easy to use an initrd on the RPi. See "using initrd" thread some days ago.

Oups,
I already read this thread, found it via forum search but didn"t realize it was just a few days old

Will continue on the other thread then!
Thanks
