npl_sycfg.h: The file cannot be accessed by the system.

When I try to run "newt upgrade" in cygwin, it will be terminated by an error. The error information is like this:

Downloading repository mynewt-nimble (commit: master) from https://github.com/apache/mynewt-nimble.git Error: open E:\Cygwin64\tmp\newt-repo605611437\porting\npl\riot\include\npl_syscfg\npl_sycfg.h: The file cannot be accessed by the system.

How can I to fix the error?

Hi,

That file is symlink so this looks like issue with cygwin environment...
I'd suggest to try run it with administrator privilege or under other environment (eg mingw)
