Hi,
   Going a little nuts. I managed to boot and install OPNSense on my new server (SolidRun Bedrock v3000) and it is using a not so standard MMIO serial console. I can interrupt the loader at boot and add the appropriate hw.uart.console, but I am stumped on how to permanently configure this.

at initial boot I put this manually in the loader
hw.uart.console="mm:0xfedc9000,rs:2"

serial console works fine if i manually set it at boot time

I have tried adding it to tunables with no success and trying /boot/loader.conf.local

It appears to be using /dev/ttyu0 for the console when working.

OPNsense 23.7.r2-amd64
FreeBSD 13.2-RELEASE-p1

CPU type   AMD Ryzen Embedded V3C18I 8-Core Processor (8 cores, 16 threads)
