Thanks Robert,



BB-UART4-00A0.dtbo is present in /lib/firmware.  I’ve not had an issue before 
but this is a freshly flashed Jessie BBB.




dmesg shows the following which is the same error as per the first post when 
echoing into the slots.





[    4.968908] __of_adjust_tree_phandle_references: Could not find target 
property 'fixup' @/__local_f

ixups__

[    4.979738] bone_capemgr bone_capemgr: slot #4: Failed to resolve tree

[    4.987236] bone_capemgr bone_capemgr: loader: failed to load slot-4 
BB-UART4:00A0 (prio 0)
