Today I had time to return to nuttx and rebased to master. But after doing a distclean and configuration, the build process on MSYS2 is extremely slow. It takes hours for a build with "make -j8 V=1". I already had my company admin disable antivirus. Had there been a change in the process?
I use both MSYS2 and Cygwin (really both Cygwin) and have not noticed any slowdown using Cygwin ... still minutes, certainly not hours. I haven't used MSYS2 in some time.
Perhaps you could do a git bisect and see if there is some particular commit that introduced the MSYS2 problem
