I have configured the tftp server and tftproot directory for freebsd. After the firmware is loaded the u-boot runs. I am not sure what file to provide via tftp to boot further. If I provide loader.efi then its looks for and unable to /boot/lua/loader.lua. This file is in tftproot directory however loader is unable look for it. Or should I be configuring pxelinux.cfg/default because that is first thing the firmware looks for?
