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 were 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:

  1. cd /usr/src
  2. git clone https://github.com/crust-firmware/meta.git
  3. cd /usr/src/meta



Edit the following file Make file

  1. Cross compiler

CROSS_aarch64 = aarch64-linux-musl- CROSS_or1k = or1k-linux-musl-

  1. General options

DEBUG ?= 0 REPRODUCIBLE ?= 0

  1. Board selection

BOARD ?= pinebook


Example:

  1. Cross compiler

CROSS_aarch64 = /usr/bin/aarch64-linux-gnu- CROSS_or1k = /opt/or1k-linux-musl-cross/bin/or1k-linux-musl-

  1. General options

DEBUG ?= 0 REPRODUCIBLE ?= 0

  1. Board selection

BOARD ?= pinephone
