hello , i use opi pc +

 

i was install armbian in emmc with nand-sata-install without problems. so after a few mouths of work i would backup emmc.

i plug an sd in a usb reader and launch nand-sata-install. i has been just one choise: "boot to sd , systeme on sata usb".

all copy was good. but now opi boot only with sd card plug in the usb reader or with a fresh image in sd slot.

if i try nand-sata-install from usb reader , i have error message "this toll must run  from sd card!"

how is it possible to reinstall old systeme (with all my work) in emmc.

 

thanks.

Nand-sata-installer is not a eMMC backup tool, not designed for such scenarios ... it's job is to transfer data from SD media somewhere else and adjust boot scripts, install bootloader, ...

thanks.

I try your command from fresh dedian console (boot with sd card) , i must modifie to :

dd if=/usr/lib/linux-u-boot-orangepipcplus_5.20_armhf/u-boot-sunxi-with-spl.bin of=/dev/mmcblk1 bs=1024 seek=8

/usr/lib/linux-u-boot-orangepipcplus_5.20_armhf/u-boot-sunxi-with-spl.bin find in debian sd

and of=/dev/mmcblk1 because i haven't mmcblk2 in /dev/

no errors in console , i try to reboot without sd card : no succes

Gave up waiting for root device. common problemes:

       -Check root= (did the systeme wait for the right device ?)

  -missing modules (cats /proc/modules; ls /dev)

alert! /dev/disk/by-uuid/39e............1b7e doesnot exist. dropping to a shell!

rebooting automatically due to panic = boot argument.

 

 

to finish i can't check rootdev is set properly in my  /boot/boot.cmd because i don't no how do that.

Boot from SD again, then do "mount /dev/mmcblk1p1 /mnt", then check /mnt/boot/boot.cmd and make sure the rootdev=/dev/mmcblk1p1.

Also check the same thing in /mnt/boot/armbianEnv.txt (I'm not sure if this file exist in older 5.20).

Check the /mnt/etc/fstab too for the device or UUID used in "/" partition.

(If some UUID is used, check what "blkid" is reporting)

thanks for reply.

1) i mount mmcblk1p1 and there's no line rootdev in boot.cmd , where add this? and must i run "mkimage -C none -A arm -T script -d /mnt/boot/boot.cmd /mnt/boot/boot.scr" after change boot.cmd.

strangely in line 11 , root=uuid=39e06b78-4f68-4cfb-a505-c7bd1f801b7e is different of  uuid mmcblk1p1  in /dev/disk/by-uuid/a80ecb16-1adb-4a2b-ad23-b15d3b4f7517 maybe must i change this too?

 

 

2) i havn't /mnt/boot/armbianEnv.txt.

 

3) /mnt/etc/fstab:

/dev/mmcblk1p1 / ext4 defaults,noatime,nodiratime,commit=600,errors=remount-ro 0 1
tmpfs /tmp tmpfs defaults,nosuid 0 0
/var/swap none swap sw 0 0

There is a lot of changes that occured between 5.20 and 5.24, so don't worry about things that are missing, it would be useless to add them.

But for root=UUID, yes, you need to fix that, either by placing proper one, or simply by using "root=/dev/mmcblk1p1".

Yes, you will need to use mkimage command to get the boot.scr updated, then reboot without SD.

I modified boot.cmd as below:

gpio set PL10
gpio set PG11
setenv machid 1029

if ext4load mmc 0 0x00000000 /boot/.verbose
then
setenv verbosity 7
else
setenv verbosity 1
fi

fi

and run :

 mkimage -C none -A arm -T script -d /mnt/boot/boot.cmd /mnt/boot/boot.scr

allways run fail without sd.

it seems boot is ok but kernel launch error.

"/dev/disk/by-uuid/39e.......... doesnot exist" was change by "/dev/disk/mmcblk1p1 doesnot exist" indicate boot.scr has been updated but after.....why doesn't exist mmcblk1p1????

( i not include rootdev line . must include at end of boot.cmd?)

You seems to be at 2 inch from success ...

 

The "disk" in /dev/disk/mmcblk1p1 should not be there ...

 

Maybe the error isn't in boot.cmd, since you provide proper root there.

 

Did you check again in /etc/fstab of the eMMC ? (so in /mnt/etc/fstab when mounted from sd boot)

yes 2 inch it is better than nothink :)

 

i recheck /mnt/etc/fstab:

/dev/mmcblk1p1 / ext4 defaults,noatime,nodiratime,commit=600,errors=remount-ro 0 1
tmpfs /tmp tmpfs defaults,nosuid 0 0
/var/swap none swap sw 0 0

i see nothing wrong . maybe try /dev/mmcblk1? or reload just kernel core?

 

thanks again for your help ang youtr time.

Don't sorry you spent verry time to help me, and the mistake was mine. yesterday i try to explore nand -sata-install script to try to understand how it work and try some commandes. and one time i have a rebbot on emmc but with sd plugged.... very strangely. i continue to rummage this emmc.

So,in finnaly if i find nothing, i know how access emmc data from sd boot, i will backup this on usb key , execute nand-sata-install from fresh debian sd card and manualy copie datato emmc  from backup.
