mobian-recipes

A set of debos recipes for building a debian-based image for mobile phones, initially targetting Pine64's PinePhone.

Prebuilt images are available here.

The default user is mobian with password 1234.

Build

To build the image, you need to have debos and bmaptool. On a debian-based system, install these dependencies by typing the following command in a terminal:

sudo apt install debos bmap-tools f2fs-tools

Do note that the debos provided in Debian 10 (Buster) is not new enough (it will error out with "Unknown action: recipe"), the one in Debian Bullseye works. If you want to build with EXT4 filesystem f2fs-tools is not required.

The build system will cache and re-use it's output files. To create a fresh build remove *.tar.gz, *.sqfs and *.img before starting the build.

If your system isn't debian-based (or if you choose to install debos without using apt, which is a terrible idea), please make sure you also install the following required packages:

debootstrap
qemu-system-x86
qemu-user-static
binfmt-support
squashfs-tools-ng (only required for generating installer images)

Then simply browse to the mobian-recipes folder and execute ./build.sh.

You can use ./build.sh -d to use the docker version of debos.

Building QEMU image

You can build a QEMU x86_64 image by adding the -t amd64 (UEFI) or -t amd64-legacy (BIOS) flags to build.sh

The resulting files are raw images. You can start qemu like so:

qemu-system-x86_64 -drive format=raw,file=<imagefile.img> -enable-kvm -cpu host -vga virtio -m 2048 -smp cores=4 -bios <uefi-firmware>

If you have built the BIOS image you can drop the -bios <uefi-firmware> flag. On a gentoo system f.e. the uefi firmware can be found under /usr/share/edk2-ovmf/OVMF_CODE.fd

You may also want to convert the raw image to qcow2 format and resize it like this:

qemu-img convert -f raw -O qcow2 <raw_image.img> <qcow_image.qcow2>
qemu-img resize -f qcow2 <qcow_image.qcow2> +20G

Install

Insert a MicroSD card into your computer, and type the following command:

sudo bmaptool copy <image> /dev/<sdcard>

or:

sudo dd if=<image> of=/dev/<sdcard> bs=1M

Note: Make sure to use your actual SD card device, such as mmcblk0 instead of <sdcard>.

CAUTION: This will format the SD card and erase all its contents!!!
