Summary:
A variety of howto's for PinePhone
 
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
 
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..

-When the user has a volume key pressed volume_key variable will
-contain either value 'down' or 'up', otherwise it will be empty.
