That is why I reran the script on a Beaglebone, hoping that would install the script. Mind you, I am not a pkg specialist. I do not know how to find out how this script is created and where it is supposed to put. I looked in /usr/port/sysutils/u-boot-master and /usr/port/sysutils/u-boot-beaglebone, but could not understand where this boot.scr was supposed to go >> >>> That resulted in the message that there was no device tree: >>> ===== >>> Loading Environment from EXT4... >>> ** Unable to use mmc 0:1 for loading the env ** >>> Board: BeagleBone Black >>> <ethaddr> not set.

I don’t know why that stuff is not in torvalds tree. I know that the debian version is created from https://github.com/RobertCNelson/omap-image-builder So my question would be then revolve around: how can I add that version to FreeBSD arm? Is there some procedure documented somehwere how I should do this? Kind Regards, Johan Henselmans
