Rk2Aw BootLoader & Multi-Distro on SD Card for PinePhonePro

References: https://xff.cz/kernels/rk2aw/rk2aw-rk3399-pinephone-pro/INSTALL and https://xnux.eu/rk2aw/

Requirements: SSH connection from linux machine to PinePhonePro, internet connection.

Note: Preloader and userspace utility to flash it are non-free.

Thanks: Megi at https://xnux.eu/log/

Flash Rk2Aw BootLoader to SPI

1. Connect PinePhonePro to linux machine and start a ssh connection
2. ssh <user>@<phoneip> # set a connection
3. cd ~/Downloads # enter to directory
4. curl -O https://xff.cz/kernels/bootloaders/ppp.tar.gz # download installer
5. tar -xvzf ppp.tar.gz -C ~/Downloads # extract
6. # scp -r ~/Downloads/ppp <user>@<phoneip>:~/Downloads # copy to phone, non needed
7. sudo ./spinor-flash-initial-setup.sh # flash SPI

Flash Multi-Distro SD Card

1. Get distro compressed images and decompress them. (i.e. Manjaro.phosh.beta34, Mobian.6.1, ArchLinux)
2. Mount distro images both partitions "/boot", "/root" for each distro
3. lsblk # find /loop, /sd references. Use blkid to see the UUID for the partition

6. Partition sd card (min 6432GB)

Rk2Aw BootLoader & Multi-Distro on eMMC for PinePhonePro

Make sure you boot from the SDcard in your PPP as we are going to be building the eMMC. Note that below, arch is booted from the SDcard and the SDcard shows as /dev/mmcblk1

Flash Rk2Aw BootLoader to SPI

Same as above. Note this installs rk2aw and a bootloader to SPI NOR flash. Resulting SPI status is as follows:

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.

Mount the images

sudo su # login with your psw

Follow-up comments

1. On first boot neither phosh nor sxmo resized their partition - sudo resize2fs sorted that.
2. Any time an update rebuilds the initramfs it is necessary to delete /boot/boot.scr again to keep the rk2aw menu clean.
3. The end result is a boot screen as follows:
