OpenBSD/armv7 on the CubieBoard2

· OpenBSD

I bought the CubieBoard2 back in 2016 with the idea to run OpenBSD on it, but because of various reliability issues with the onboard NIC, it ended up running NetBSD for a few weeks before ending up in a drawer.

Back in October, Mark Kettenis committed code to allow switching to the framebuffer "glass" console in the bootloader on OpenBSD/armv7, making it possible to install the system without using a serial cable.

>> OpenBSD/armv7 BOOTARM 1.14
boot> set tty fb0
switching console to fb0

This prompted me to plug the board again, and having support for the framebuffer console is a game changer. It also allows running Xenocara, if that's your thing.

Here is the output of running file on executables:

ELF 32-bit LSB shared object, ARM, version 1

And this is the result of the md5 -t benchmark:

MD5 time trial.  Processing 10000 10000-byte blocks...
Digest = 52e5f9c9e6f656f3e1800dfa5579d089
Time   = 1.340000 seconds
Speed  = 74626865.671642 bytes/second

For the record, LibreSSL speed benchmark results are available here.
