NetBSD on the CubieBoard2

· NetBSD

Here are some notes on installing and running NetBSD/evbarm on the AllWinner A20 powered CubieBoard2. I bought this board a few weeks ago for its SATA capabilities, despite the fact that there are now cheaper boards with more powerful CPUs.

Required steps for creating a bootable micro SD card are detailed on the NetBSD Wiki, and a NetBSD installation is required to run mkubootimage.

I used an USB to TTL serial cable to connect to the board and create user accounts. Do not be afraid of serial, as it has in fact only advantages: there is no need to connect an USB keyboard nor an HDMI display, and it also brings back nice memories.

Connecting using cu (from my OpenBSD machine):

cu -s 115200 -l /dev/cuaU0

Device name might be different when using cu on other operating systems.

Adding a regular user in the wheel group:

useradd -m -G wheel username

Adding a password to the newly created user and changing default shell to ksh:

passwd username
chpass -s /bin/ksh username

Installing and configuring pkgin:

export PKG_PATH=http://cdn.netbsd.org/pub/pkgsrc/packages/NetBSD/earmv7hf/7.0/All
pkg_add pkgin
echo $PKG_PATH > /usr/pkg/etc/pkgin/repositories.conf
pkgin update

Finally, here is a dmesg for reference purposes:
