Though the documentation says that we should always take commit hash matching with the submodule HEAD, the commit id that you found in the documentation (i.e 19a6ceb) is the last one that has been thoroughly tested. You might want to use that id and build the dtb. To build the DTB, you can use the script provided by FreeBSD in the following source directory: sys/tools/fdt/make_dtb.sh And the right dts to build is sys/gnu/dts/arm/am335x-boneblack.dts > > Can anyone point me to where HEAD is determined?
