Installing to eMMC

Hi all,

Odroid N2 with CE 19.3 on eMMC. CE 20.0 on uSD Card.

Followed these instructions, Option B:μsd_card

Used the installtoemmc command. CE 20.0 is now on my eMMC however the contents of /storage/downloads that was on 19.3 is also on 20.0. Plus add-ons like OpenVFD that were on 19.3 and not on 20.0 on uSD are now on 20.0 on eMMC. Also I had Entware on 19.3 and not on 20.0 but /storage/.opt is on 20.0 on uSD.

I would have thought the eMMC would have been wiped before installing the contents of the uSD.


Everything should be wiped and current uSD card copied to eMMC.

Can you run command again and copy here the output you get by command?

I don´t understand, sorry.

My way(without sd card):

  1. backup
  2. fresh install to eMMC via eMMC adaptor
  3. replace eMMC module
  4. restore

And if you don’t have adapter? Then script can be used.

My opinion:
don´t buy any eMMC module without USB Adapter, it´s so cheap

Yes, your opinion. And useful comment for future buyers. But for buyers without adapter it means nothing.

Sorry, but any user without adapter would be able to buy one.
My intention was only the information that it is much easier with the adapter.

Yep, will do later today and will post output.

Here is the log:

EDIT: This is interesting:

N2:~ # installtoemmc > log.txt

mkfs.vfat: /dev/mmcblk0p1 contains a mounted filesystem.
/dev/mmcblk0p2 is mounted; will not make a filesystem here!
N2:~ #

Don’t redirect output to file because now it is not really clear which line comes where.

But as you can see /dev/mmcblk0p1 and p2 are still mounted that’s why old files stays there.

And I hope you are booting from uSD card and not from eMMC? What you get by command
