--Apple-Mail=_D2A51642-4BF0-481E-B00E-57F550686EE1 Content-Transfer-Encoding: 7bit Content-Type: text/plain; charset=us-ascii I've just committed changes so that BeagleBone images (built with my scripts) no longer use the compiled-in FDT. (This includes changes to FreeBSD ubldr, to U-Boot, and to my scripts.) RaspberryPi has not been using the compiled-in FDT for some time now. My goal is demonstrate booting a single kernel on multiple ARM boards, which necessarily precludes using a compiled-in FDT. I plan to soon comment-out the compiled-in FDT from the kernel configurations in FreeBSD SVN for both BeagleBone and RaspberryPi. For reference, you can load an FDT from U-Boot: $ fatload mmc 0:1 <address> <filename.dtb> $ fdt addr <address> or from within ubldr: $ load -t fdt <filename.dtb> These commands can be easily automated. In either case, ubldr should now find the FDT and correctly pass it to the kernel.
