OrangePi5Plus

This is notes on the 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

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

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.
