Wondering if it is possible to replace pfsense (freebsd 14) with Armbian on a netgate sg-2100 appliance? https://shop.telappliant.com/product/sg-2100-pfsense-security-gateway-appliance/ I have the version with an additional 32GB M.2 SSD and it looks like the mvebu_armada-37xx board is supported by the generic Armbian, but I struggle to get from u-boot to starting the installer from usb (used the Armbian_23.5.1_Uefi-arm64_bookworm_current_6.1.30_minimal.img), with the usbboot command. Below is the current u-boot environment. I have masked some parts with "xxxxx" and probably won't need half of these variables, as they are very vendor specific, for example netgateid etc. If possible, I would like to flash/replace the boot loader that is not specific for pfsense, but I am a total beginner with arm boards and boot loaders. Not as easy as installing various Linux distros...
