How to fix the problem ' fatal: Not a git repository: XXXX'

[newmsg]

Hello,

I used the cmd git submodule update --init --recursive to update all submodules of px4 like this:

$ git submodule update --init --recursive

Failed to recurse into submodule path 'src/lib/DriverFramework'

I found the following error:

fatal: Not a git repository: j:/PX4_SRC/Firmware/.git/modules/src/lib/DriverFramework/modules/cmake/cmake_hexagon
Unable to find current revision in submodule path 'cmake/cmake_hexagon'

However, the absolute path is "J:\PX4_SRC\Firmware\cmake\cmake_hexagon"
instead of "src/lib/DriverFramework/modules/cmake/cmake_hexagon"

How to fix it? Thank you in advance!

any help would be appreciated!
