I'm trying to build kwboot on FreeBSD but the latest source I found is not posix compliant, containing various Linuxisms... I did find an old version here https://github.com/LeMaker/u-boot/raw/master/tools/kwboot.c that I was able to compile. Is there anything newer? Alternatively is anyone aware of a binary which works on FreeBSD?
