Hardware and Performance / Re: [Work In Progress] OPNsense Ported into ARM Devices

1) On a FreeBSD machine, pkg install u-boot-rockpro64
2) Then from /usr/local/share/u-boot/u-boot-rockpro64 pick up idbloader.img and u-boot.itb
3) Overwrite the boot loader on the OPNsense-22.1-OpenSSL-arm-aarch64-R4S.img (which is for Nanopi-R4S) with the boot loader for ROCKPro64
dd if=u-boot-rockpro64/idbloader.img of=OPNsense-22.1-OpenSSL-arm-aarch64-R4S.img seek=64 bs=512  conv=notrunc
dd if=u-boot-rockpro64/u-boot.itb of=OPNsense-22.1-OpenSSL-arm-aarch64-R4S.img seek=16384 bs=512 conv=notrunc
Note: conv=notrunk prevents the output file from being truncated after the end of the respective boot images.
