I can't = get any activity out of it with FreeBSD, however. I'm using FreeBSD-11-CURRENT, and the boot image is based on an = 11-CURRENT "official" download, but I added a very recent build of = sysutils/u-boot-rpi2. I can build CURRENT on the machine (using a USB SSD, manually mounted), = and I made sure I had the latest RPI2.DTB file in the FAT partition. The screen stays stubbornly OFF. Here is the relevant extract of CONFIG.TXT: hdmi_force_unplug=3D1 or hdmi_force_hotplug=3D1 or #hdmi_safe=3D1 or hdmi_ignore_edid=3D0xa5000080 hdmi_drive=3D2 hdmi_group=3D2 hdmi_mode=3D28 ... and I've tried a couple of combinations of the above with no luck. I = can make an HDMI TV work, but not the inbuilt ribbon-cable interface. I suspect the DTB file as FreeBSD's is much smaller than RaspBian's, but = I'm not all that clued in that department. Has anyone had any better luck than me?
