Install opnSense

Link:  PC Engine howto - OS Installation - opnsense
Download opnSense
  • download the latest serial amd64 installer for OPNSense (e.g. OPNsense-17.7-OpenSSL-serial-amd64.img.bz2
  • Write image to an USB stick using Etcher (Etcher is a graphical writing tool for Mac OS, Linux and Windows)
  • boot apu2 from USB with installed mSATA/SD
  • follow the instructions of the installer

Important: the SD slot on the apu2 boards is directly connected to the CPU and needs the module SDHCI to work.
Do not use an SD to boot FreeBSD based OS like pfSense and OPNSense on apu2 boards. Only very recent kernel versions fully support booting via SDHCI.
Try an USB-SD adapter in case of related troubles. If it works with the USB-SD adapter, but not in the SD slot, then the SDHCI module is missing ...
