I'm trying to do this on my BBB with Debian but I'm getting a compile error:
debian@bbblack:~/dtb-rebuilder$ make DTC src/arm/am335x-base0033.dtb /bin/sh: 1: dtc: not found make[1]: *** [src/arm/am335x-base0033.dtb] Error 127 make: *** [all_arm] Error 2 debian@bbblack:~/dtb-rebuilder$ I followed the custom dtb directions in the link.
