[Solved] Multiple partition setup issues

[john3voltas]

Hi there,
I like to keep the rootfs and boot in separate ext4 and ext2 partitions, respectively,
For that in the past I have used this tutorial.
viewtopic.php?f=30&t=1325&start=10

It just so happens that my old pendisk has died and I had to buy another one and I am trying to reinstall using the same tutorial but it is failing me with a kernel panic.

Here is a copy of the env:
$this->bbcode_second_pass_code('', 'DockStar> printenv
baudrate=115200
bootcmd=usb start; setenv letter 9;for type in usb; do for disk in 0 1 2 3; do if ${type} part ${disk};then setexpr letter $letter + 1;run load;fi;done;done;
bootdelay=3
bootm=echo Booting from ${disk} ...; run setargs; bootm ${loadaddr};

And here is a copy of the boot log using the serial:

Here is my current fstab:
$this->bbcode_second_pass_code('', '/dev/sda1 /boot ext2 defaults,noatime 1 2')

Have already tried this fstab as per the tutorial with the same results:
$this->bbcode_second_pass_code('', '/dev/sda1 /boot ext2 defaults,noatime 1 2
/dev/sda2 / ext4 noatime 0 1')

What could I possibly be doing wrong...
Thanks in advance.

Cheers

That thread is really, really old and does not apply to your uboot at all since u-boot environment has changed a lot.

$this->bbcode_second_pass_code('', 'usb_rootfstype=ext4
usb_scan_1=usb=0:1 dev=sda2
usb_scan_2=usb=1:1 dev=sdb2
usb_scan_3=usb=2:1 dev=sdc2
usb_scan_4=usb=3:1 dev=sdd2')
This has no effect all.

1. Your 2014 version of U-Boot already supported linux-kirkwood-dt kernel. It also did support booting off of ext4 drive.
2. I was under impression you wanted to have two separate partitions for boot and rootfs.
3. I can't think of any drawbacks on these devices to have /boot within rootfs. If anything it makes things a lot simpler. If you still want to go with 2 partitions, then you can either create a file called uEnv.txt on the first partition and put in it "root=PARTUUD=xxxxxxx" or set the varialbe "root=PARTUUD=xxxxx" in the environment. You can find out partition PARTUUID with "blkid".
