Yeah I’ve just upgraded to the last PCEngines firmware release, before they changed name to Dasharo.

See the notice at https://pcengines.github.io/

It’s a bit fiddly to upgrade firmware as OpenWRT is built without flashrom support enabled by default, and the alternative was using a USB->Serial cable and booting into a Debian Live console session. Apparently a bit easier to do this if running opnsense on the hardware.
