Sophisticated chroot/build/flash tool to develop and install postmarketOS.

For in-depth information please refer to the postmarketOS wiki.

Requirements

• 2 GB of RAM recommended for compiling
• Linux distribution (x86_64 or aarch64)
  • Windows subsystem for Linux (WSL) does not work! Please use VirtualBox instead.
  • Kernels based on the grsec patchset do not work (Alpine: use linux-vanilla instead of linux-hardened, Arch: linux-hardened is not based on grsec)
• Python 3.4+
• OpenSSL

Usage

Assuming you have a supported device, you can build and flash a postmarketOS image by running through the following steps. For new devices check the porting guide.

First, clone the git repository and initialize your pmbootstrap environment:

$ git clone https://github.com/postmarketOS/pmbootstrap
$ cd pmbootstrap
$ ./pmbootstrap.py init

While running any pmbootstrap command, it's always useful to have a log open in a separate window where further details can be seen:

$ ./pmbootstrap.py log

It's now time to run a full build which will create the boot and system images:

$ ./pmbootstrap.py install

Once your device is connected and is ready to be flashed (e.g. via fastboot), you can run a flash of the kernel (boot) and system partitions:

$ ./pmbootstrap.py flasher flash_kernel
$ ./pmbootstrap.py flasher flash_system

After a reboot, the device will provide a USB network interface, which we request an IP from, and telnet into to open the full-disk encryption on the main system partition:

$ dhclient -v enp0s20f0u1
$ telnet 172.16.42.1

Trying 172.16.42.1...
Connected to 172.16.42.1.
Escape character is '^]'.

Enter passphrase for /dev/mapper/mmcblk0p25p2:
Connection closed by foreign host.

Once the partition has been unlocked it is possible to connect via SSH:

$ ssh [email protected]

Development

Testing

Install pytest (via your package manager or pip) and run it inside the pmbootstrap folder.
