Yeah, you're modifying the wrong file. debian@beaglebone:~/nfs$ cat /boot/uEnv.txt #Docs: http://elinux.org/Beagleboard:U-boot_partitioning_layout_2.0
uname_r=4.4.12-ti-r31 #uuid= #dtb= ##BeagleBone Black/Green dtb's for v4.1.x (BeagleBone White just works..) *##BeagleBone Black: HDMI (Audio/Video) disabled:dtb=am335x-boneblack-emmc-overlay.dtb* . . . *dtb=am335x-boneblack-emmc-overlay.dtb *is the line you're after, and it probably is proceeded by a pound( # ) symbol. So it's commented out. SImply remove the # to uncomment, and then reboot the board.
