This is notes on the [http://www.orangepi.org/html/hardWare/computerAndMicrocontrollers/details/Orange-Pi-5-plus-32GB.html Orange Pi 5 Plus] Arm mini PC I was given.

= OS =

I went with armbian but using the vendor kernel. This is important or the 5120x2160 display won't work.

However 3d aceleration doesn't work in it, and further testing got it all messed up. I need to figure this out.

= EMMC =

I got the 256 GB EMMC card option, so I can used this rather than sdcard

== moving data to the emmc with lvm ==

I wanted to use LVM thin on the emmc as I do with all my installs. This wasn't too bad, just not documented.

=== update the spi flash ===

armbian-config
System > Storage > 7 Install/Update the bootloader on MTD Flash

== Provision the EMMC ==
the following needs to be provisioned on the disk. the emmc is /dev/mmcblk0, but you need to verify this.

gdisk

Disk /dev/mmcblk0: 488554496 sectors, 233.0 GiB
Sector size (logical/physical): 512/512 bytes
Disk identifier (GUID): 0ABE2288-4E11-4606-96A9-D9BDA03F4193
Partition table holds up to 128 entries
Main partition table begins at sector 2 and ends at sector 33
First usable sector is 34, last usable sector is 488554462
Partitions will be aligned on 2048-sector boundaries
Total free space is 4029 sectors (2.0 MiB)

Number Start (sector) End (sector) Size Code Name
1 2048 1050623 512.0 MiB 8300 Linux filesystem
2 1050624 68159487 32.0 GiB 8200 Linux swap
3 68159488 488552447 200.5 GiB 8E00 Linux LVM

== Provision the LVM ==
install needed tools
apt install lvm2 zfs-initramfs lvm2 thin-provisioning-tools uuid-runtime

Make a physical volume for LVM
pvcreate /dev/mmcblk0p3

Make a emmc Volume Group
vgcreate emmc /dev/mmcblk0p3

Make a Thin Pool in the Volume Group
lvcreate -l 100%FREE -T emmc/thinpool

Make a Logical Volume in the Thin Pool
lvcreate -V128G emmc/thinpool -n root

== Copy root of sdcard to emmc ==
fstrim
time dd if=/dev/mmcblk1p1 of=/dev/mapper/emmc-root bs=1M conv=sparse

This will dd it, from a live system, so best to do this just after boot with nothing running.

== Fix the file system ==
You need to fix up and change the filesystem on the emmc now since it was copied raw.
e2fsck -f /dev/mapper/emmc-root
Now expand it
resize2fs /dev/mapper/emmc-root
Now change the UUID
tune2fs -U $(uuidgen) /dev/mapper/emmc-root

== Format the other disks ==
Boot needs to be ext2fs
mkfs.ext2 /dev/mmcblk0p1
Swap needs to be setup
mkswap /dev/mmcblk0p2

== Verify the UUID's ==
These are the UUID's you'll need for the next part.

lsblk -f
NAME FSTYPE FSVER LABEL UUID FSAVAIL FSUSE% MOUNTPOINTS
mmcblk0
├─mmcblk0p1 ext2 1.0 fcaea592-6e1b-4380-9e41-8ec7f438965e

Summary
boot = fcaea592-6e1b-4380-9e41-8ec7f438965e
rootfs = de88d702-b9a9-4577-9d56-a46e557d0c6b
swap = b56855cc-db23-434b-90bc-7f5f2fa97e89

== mount it and make changes ==

make a directory to mount the emmc to
mkdir /newroot

mount the emmc
mount UUID=1a409081-4de1-4995-bdb7-eabcf386e7fb /newroot

setup the various proc files to work when you change root
cd /newroot/
mount -t proc /proc proc/
mount --rbind /sys sys/
mount --rbind /dev dev/

Mount the boot device
mount /dev/mmcblk0p1 /newroot/boot/

Copy the boot to this new directory
cp -av /boot/ /newroot/

chroot to /newroot and make changes to make the system bootable
chroot /newroot/

edit /etc/fstab
vim /etc/fstab

UUID=de88d702-b9a9-4577-9d56-a46e557d0c6b / ext4 defaults,noatime,commit=120,errors=remount-ro 0 1
UUID=b56855cc-db23-434b-90bc-7f5f2fa97e89 swap swap defaults 0 0
UUID=fcaea592-6e1b-4380-9e41-8ec7f438965e /boot ext2 defaults,noatime 0 1
tmpfs /tmp tmpfs defaults,nosuid 0 0

edit the armbianenv file in boot
vim /boot/armbianEnv.txt
change the rootdev= to the UUID of the lvm on emmc
rootdev=UUID=de88d702-b9a9-4577-9d56-a46e557d0c6b

Update initramfs
update-initramfs -u -k all

sync and reboot (remove the sdcard!)
sync
reboot

== Verify ==
the system should reboot and read the emmc now without an sdcard installed.
