PinePhone Pro/Create a multi-distribution image using rk2aw
This article explains how to create a multi-distribution image on the PinePhone Pro using rk2aw.
Multi-distro on microSD Card
This article explains how to install megi's rk2aw loader, U-Boot to SPI and a multi-distribution image to the microSD card and/or eMMC of the PinePhone Pro. Further instructions regarding rk2aw can be found on megi's website under https://xff.cz/kernels/rk2aw/rk2aw-rk3399-pinephone-pro/INSTALL. Please note that loader and userspace utility to flash it are free, but not open-source.
Flash rk2Aw loader to SPI
Connect PinePhone Pro to a Linux machine, start a ssh connection and download installer to flash pre-loader to the phone's SPI.
ssh <user>@<phoneip> cd ~/Downloads curl -O https://xff.cz/kernels/bootloaders/ppp.tar.gz tar -xvzf ppp.tar.gz -C ~/Downloads # scp -r ~/Downloads/ppp <user>@<phoneip>:~/Downloads # copy to phone, non needed sudo ./spinor-flash-initial-setup.sh
Build multi-distro on the microSD card
If necessary wipe the microSD card
sudo dd if=/dev/zero of=/dev/sdb count=1 bs=32768 status=progress # quick way i.e. # 32GB SDcard (30989615104bytes/32768dim=1volta) sudo dd if=/dev/zero of=/dev/sdb count=945728 bs=32768 status=progress # slow way i.e. # 32GB SDcard (30989615104bytes/32768dim=945728volte) sudo dd if=/dev/zero of=/dev/sdb count=15271040 bs=4096 status=progress # 63GB SDcard (62550179840bytes/512dim=122168320volte)

Get image files of the distributions
Get the compressed distribution images from PinePhone Pro Software Releases, decompress them and mount both partitions "/boot", "/root" from each distro.
Change the directory to the Downloads folder.
cd ~/Downloads
Get images. Example releases (update the syntax to newer releases).
wget https://github.com/dreemurrs-embedded/Pine64-Arch/releases/download/20230203/archlinux-pinephone-pro-phosh-20230925.img.xz wget https://github.com/manjaro-pinephone/phosh/releases/download/beta35/Manjaro-ARM-phosh-pinephonepro-beta35.img.xz wget https://images.mobian.org/pinephonepro/weekly/mobian-pinephonepro-phosh-20231008.img.xz wget https://images.postmarketos.org/bpo/v23.06/pine64-pinephonepro/phosh/20230904-0846/20230904-0846-postmarketOS-v23.06-phosh-22.2-pine64-pinephonepro.img.xz wget https://ci.ubports.com/job/focal-hybris-rootfs-arm64/job/master/lastSuccessfulBuild/artifact/ubuntu-touch-pinephone-pro-img-arm64.raw.xz

For PostMarketOS you can also use bootstrap to generate distro image. Make sure you install pmbootstrap before building images
git clone --depth=1 https://git.sr.ht/~postmarketos/pmbootstrap mkdir -p ~/.local/bin ln -s "$PWD/pmbootstrap/pmbootstrap.py" ~/.local/bin/pmbootstrap source ~/.profile # remember to update your environment pmbootstrap --version # If this returns error, put ~/.local/bin in your PATH, adding the following to your ~/.profile (zsh: ~/.zprofile). # PATH="$HOME/.local/bin:$PATH" # optional
Create 2GB empty image file, format and mount it.
sudo dd if=/dev/zero of=postmarketOS-edge.img bs=1 count=0 seek=2G status=progress && sync sudo mkfs.ext4 postmarketOS-edge.img sudo su losetup -P /dev/loop0 postmarketOS-edge.img exit

Switching On Device
According to rk2aw info, to operate your PinePhonePro you can:
Plug in USB power button. Led blinks: 0.5s on, 0.5s off. Battery is charging.
Press shortly power button. Graphical menu appears, than just press onto the image to boot from.
Press power button longer. Led starts to blinks rapidly, release power button and led blinks N times each second according to the flashed images. In example: Led blinks once each second and 1st image is selected Led blinks twice each second and 2nd image is seleted Led blinks triple each second and 3rd image is selected Press shortly to move to next image. Press longer to boot the selected image.
In case you hold the power button too long, the device is forced to power off.
Multi-distro on eMMC
Make sure you boot from the microSD card in your PinePhone Pro as we are going to overwrite the eMMC. Note that below, Arch is booted from the microSD card and the microSD card is listed as the device /dev/mmcblk1.
Flash rk2Aw loader to SPI
Same as above. Note this installs rk2aw and a bootloader to SPI NOR flash. Resulting SPI status is as follow:

Build multi-distro eMMC
In this example we are going to build 2 partitions on the eMMC, the first with Arch/Phosh and the second with Arch/sxmo. We have already downloaded the images from Danct12 and decompressed them.

Follow-up comments
- On first boot neither Phosh nor sxmo resized their partition - sudo resize2fs sorted that.
- Any time an update rebuilds the initramfs it is necessary to delete /boot/boot.scr again to keep the rk2aw menu clean.
- In case you want to reinstall just a single distribution, the easy way is to delete an recreate partition using gParted GUI.
