Summary:
After following these steps:
- You'll have a Custom UBOOT (Crust ENABLED) that allows MultiBOOT Using 3 different OS's depending on key combo of volume up / volume down or none pressing on boot
- You'll be able to experiment on SD Card without Touching your EMMC
- You'll learn how to take a part a PINE PHONE IMAGE (most, and put each OS On one partition
=========================================================================================================
All the information here, has been discussed in the open source community on web sites. I have simply developed a process on how to do this on the pine phone.
We use utilities such as Cross Compilation, Uboot, Patches, which will be credited.
First step, make sure you have a cross compiler for your Computer, for particularly the arm device, you will need to download a few packages, I assume we're using Debian Linux (if your using another OS you can find similar commands by searching on the web or to make it simpler download a docker Debian image, and install the pre-requisites which I will list here for Debian)
You an also use vagrant/virtual box VMware or other virtualization platforms.
First please install these Dependencies:
apt-get install gcc-aarch64-linux-gnu g++-aarch64-linux-gnu build-essential autoconf libtool cmake pkg-config git python-dev swig3.0 libpcre3-dev nodejs-dev crossbuild-essential-arm64 git losetup rsync
The following main sources are needed:
This will download quite a few sources needed for Uboot and existing OS's available to PinePhone
https://github.com/crust-firmware/meta.git
We will also apply this patch:
https://megous.com/git/u-boot/patch/?id=0ab6225154c3d8b74f06fb3b181b52a9a64b4602
(I will attach the one I used I had to modify the above patch to work with the code.)
The crust-firmware also says you need to download the or1k compiler:
https://musl.cc/or1k-linux-musl-cross.tgz
I suggest untarring this in the /opt folder.
1. Once you have these dependency:
# cd /usr/src
# git clone https://github.com/crust-firmware/meta.git
# cd /usr/src/meta
Edit the following file Make file
# Cross compiler
CROSS_aarch64 = aarch64-linux-musl-
CROSS_or1k = or1k-linux-musl-
# General options
DEBUG ?= 0
REPRODUCIBLE ?= 0
# Board selection
BOARD ?= pinebook
Example:
# Cross compiler
CROSS_aarch64 = /usr/bin/aarch64-linux-gnu-
CROSS_or1k = /opt/or1k-linux-musl-cross/bin/or1k-linux-musl-
# General options
DEBUG ?= 0
REPRODUCIBLE ?= 0
# Board selection
BOARD ?= pinephone
# make
(this should take a 10-30 mins depending on speed..I hope less than 30 mins!!)
After making apply the patch..
# make again
now, go to your sdcard
(use a CLEAN scard NO Partitions)
fdisk /dev/sd#
create 4 primary partitions,
the 1rst one should be the "boot" partition containing Uboot stuff, I'd suggest a gigabyte
the other 3 could be your choice
After creating partitions flash the image:
# cd build/pinephone
Do not use wrong drive, and copy exactly as this erases and puts the new Uboot on the sdcard
the first 512 sectors are partition you do NOT want to write that or you lose your partition
# dd if=u-boot-sunxi-with-spl.bin of=/dev/sdb bs=1024 seek=8 conv=sync
make sure your disk is ok
# fdisk -l
Disk model: e microSD
Units: sectors of 1 * 512 = 512 bytes

root@wifirouter:/usr/src#
If it looks like above its ok.
Lets start with the first OS were going to use:
JUMPDRIVE (allows booting the EMMC and fixing it if we break it!!!)
Download it here:
https://github.com/dreemurrs-embedded/Jumpdrive/releases/download/0.4/pine64-pinephone.img.xz
then use losetup to mount the image to copy the files needed
root@wifirouter:/home/dave# losetup -P -f pine64-pinephone.img
it'll mount a loop back
root@wifirouter:/home/dave# ls /dev/loop0*
/dev/loop0 /dev/loop0p1
Mount there first image:
root@wifirouter:/home/dave# mkdir /media/jumpdrive
root@wifirouter:/home/dave# mount /dev/loop0p1 /media/jumpdrive/
mount the sd card:
root@wifirouter:/media# mkdir /media/boot
root@wifirouter:/media# fdisk -l
Your pine phone looks like this DO NOT TOUCH EMMC You don't need to

Now we need to create the boot.txt for uboot to load:
Your text file should look like this:

Compile the boot script:
