  • RPI 3 boot from USB drive?

    Quote from fabio70mi

    Hi,
    I'm trying the same just now with 7.95.2
    I updated root=/dev/sda2 in cmdline.txt but I think it's not enough, maybe I've to change /etc/fstab.
    (From Raspbian, /dev/sda2 contains only lost+found, strange, I will try again to create SD using win32diskimager in place of Rufus).

    I think LibreElec should give a LABEL to root partition to refer in cmdline.txt and /etc/fstab


    Also could be nice to boot LibreElec from PXE, maybe it's only more complicated the autoupdate being the firmware files loaded via tftp

    Thank you

    Just tried it and it works!
    I have loaded 7.95.2 fresh on the USB stick and before starting the rpi changed cmdline.txt from:
    boot=/dev/mmcblk0p1 disk=/dev/mmcblk0p2 quiet
    to:
    boot=/dev/sda1 disk=/dev/sda2 quiet
    That was all.
    Of course I had already made the rpi USB-boot ready with raspbian.

    @Irusak: wondering if it would be helpful to add the other parameters that raspbian has like:
    dwtc_otg.lpm_enable=0 console=serial0,115200 console-tty1 elevator=deadline fsck.repair=yes rootwait

    Any idea?

    I agree with fabio70mi that using a label rather than an address would be nicer. Don't know how that should be phrased in cmdline.txt (or elsewhere).
    As far as fstab is concerned: I cannot find it on the USB stick from my Linix Mint box!

  • RPI 3 boot from USB drive?

    I am new to this forum, so I may have missed this subject being addressed earlier!

    My question is: what is required to have LE boot from a USB drive on the RPI 3?

    Background: booting from USB is possible with Raspbian. Look at How to boot from a USB Mass Storage Device on a Raspberry Pi 3 - Raspberry Pi Documentation for a description.
    I have tested this and it works. What it does is update the firmware ofn the RPI to enable booting from USB and make some changes to have Raspbian finish the boot from USB properly. So now I have a RPI 3 that is prepared to boot from USB and I would like to boot LibreElec from USB as well.

    Questions:

    • can LibreElec be altered (by me, after installation) to do the boot properly (like: copy the start.elf and bootcode.bin files on the LibreElec image and make changes as described in the link to config.txt, cmdline.txt and fstab). Or will this kill LibreElec?
    • is the LibreElec development team planning to support this in a future release (I am now on 7.95.1)


    Any input is welcome!
