DTC issue / Illegal property (size) 'fixup' @/__local_fixups__

Hi everybody,

there is my config :

BBK Rev.C
OS ubuntu with Linux arm 4.1.18-bone-rt-r20

DTC 1.4.1-g1e75ebc9

i have an issue with my GSM internet cape, after compile my dtbo file with dtc, imposible to load it ! all OK ok on an Linux 3.8.13-bone73

Error message is :

[ 1257.261448] bone_capemgr bone_capemgr: part_number ‘INTERNET-HUB’, version ‘N/A’
[ 1257.261513] bone_capemgr bone_capemgr: slot #7: override

[ 1257.271937] bone_capemgr bone_capemgr: slot #7: Failed to resolve tree

Please have you an idea of what appened ?

Many thanks.
