Submodule update fails

Hey guys,

i tried to rebase an older Version of my px4-v4-Firmware. Now i wanted to update it with “git submodule update --init --recursive”. Sadly an error occured:
fatal: no submodule mapping found in .gitmodules for path ‘mavlink/include/mavlink/v1.0’
Does anyone of you a solution for this?
