USAGE: ${0} [-E] [-e] [-l|m|c|g|n|B] [-L [boardname]] [-a <app-dir>] <board-selection> [make-opts]
Where:
-E enforces distclean if already configured.
-e performs distclean if configuration changed.
-l selects the Linux (l) host environment.
-m selects the macOS (m) host environment.
-c selects the Windows host and Cygwin (c) environment.
2018-05-31 19:53:09 +02:00
-g selects the Windows host and MinGW/MSYS environment.
-n selects the Windows host and Windows native (n) environment.
-B selects the *BSD (B) host environment.
Default: Use host setup in the defconfig file
Default Windows: Cygwin
-L lists available configurations for given boards, or all boards if no
board is given. board name can be partial here.
-a <app-dir> is the path to the apps/ directory, relative to the nuttx
directory
<board-selection> is either:
For in-tree boards: a <board-name>:<config-name> pair where <board-name> is
the name of the board in the boards directory and <config-name> is the name
of the board configuration sub-directory (e.g. boardname:nsh), or: For
out-of-tree custom boards: a path to the board's configuration directory,
either relative to TOPDIR (e.g. ../mycustomboards/myboardname/config/nsh)
or an absolute path.
make-opts directly pass to make
