This repository can be used to create an ArchLinuxARM image for the NanoPi Neo2 board.

Modified to build a image suitable for f2fs.

Dependencies

• make
• bsdtar (libarchive)
• python2
• uboot-tools (u-boot-tools)
• swig
• dtc (device-tree-compiler)
• bison
• flex
• sudo
• fdisk
• f2fs-tools

Prerequisite

In order to build the image, you need a working ARM toolchain.

Here is a simple way to get one:

git clone https://github.com/crosstool-ng/crosstool-ng
cd crosstool-ng
./bootstrap
./configure --enable-local
make
./ct-ng aarch64-unknown-linux-gnu
./ct-ng build

NOTE: Your distro's aarch64 cross compilers might also work. (Eg: Ubuntu: gcc-aarch64-linux-gnu)

Preparing the files

Run make (specifying jobs with -jX is supported and recommended).

This will provide:

• the ArchLinuxARM aarch64 default rootfs (ArchLinuxARM-aarch64-latest.tar.gz)
• an u-boot image compiled for the NanoPi Neo2 (u-boot-sunxi-with-spl.bin)
• a boot script (boot.scr) to be copied in /boot

Installing the distribution

Run make install BLOCK_DEVICE=/dev/mmcblk0 with the appropriate value for BLOCK_DEVICE.

Ethernet

In order to get ethernet working, you will need a recent kernel (>= 4.13).

Goodies

If you have a serial cable and miniterm.py installed (python-pyserial), make serial will open a session with the appropriate settings.
