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)

First please install these Dependencies:

apt-get install gcc-aarch64-linux-gnu g++-aarch64-linux-gnuj apt-get install build-essential autoconf libtool cmake pkg-config git python-dev swig3.0 libpcre3-dev nodejs-dev apt-get install crossbuild-essential-arm64 apt-get install git

The following main sources are needed:

This will download quite a few sources needed for Uboot and existing OS's available to PinePhone
