The apu2 by PC Engines is a 64 bit single board computer with coreboot
BIOS. It only has serial output, but no graphics chip. With its 2–4
ethernet ports, it is often used to build a firewall or router.

The provided defconfig configures busybox and isolinux. It will output a
hybrid ISO image that can be written to a USB stick or burned to a CD.

Configuration based on a blogpost by Tony Arkles:

+Intro
+=====
+
+This is a board configuration for the apu2 platform by PC Engines.
+
+https://pcengines.ch/apu2.htm
+
+Since the apu2 does not have any graphical output, the default configuration
+will ensure that the kernel output as well as the login prompt will be sent to
+the serial port.
+
+How to build
+============
+
+The provided defconfig creates a hybrid isolinux image that can be booted from
+either an USB stick or a CD.
+
+    $ make pcengines_apu2_defconfig
+    $ make
+
+How to write to an USB stick
+============================
+
+Once the build process is finished you will have an image
+called "rootfs.iso9660" in the output/images/ directory.
+
+Copy the bootable "rootfs.iso9660" onto the USB stick with "dd":
+
+    $ sudo dd if=output/images/rootfs.iso9660 of=/dev/sdX bs=1M conv=fsync
+    $ sudo sync
+
+How to connect to the apu2
+==========================
+
+Connect to the DB9 serial port of the apu2 board (either directly or through a
+USB adapter) with a baudrate of 115200.
+
+For example with miniterm (part of pyserial):
+
+    $ miniterm.py -f direct /dev/ttyUSB0 115200
