This patch exports the make macro `DEVELHELP`. Without this patch, use
of the macro in the following files does not work when the macro is set
in a makefile (such as in Makefile.local or an application's makefile as
demonstrated in dist/Makefile). Inside these files `DEVELHELP` is not
defined under these conditions.
- pkg/littlefs/Makefile
- pkg/littlefs2/Makefile
- sys/stdio_null/Makefile
Note that use of the macro does work in these files when the macro is
set from the command line, without the patch. For example:
``` sh
$make DEVELHELP=1 all
```
RIOT_TEST_HASH_DIR represents the dir to generate the test-input-hash.sha1 file for
checking if a test has changed, uses BINDIR by default.
Since it defaults to BINDIR it should have no effect on running systems.
This allows a bit more fine grain control, especially when using
the compile_and_test_for_board.py script.
JLink presumably has information about the device's RAM available
internally. Not passing the precise symbol area (which would be
available in the ELF file) because a) that'd make the terminal break
when the flashed firmware does not equal the built one, and b) that
would introduce a dependency from `term` to the ELF file that other
terminals don't have.
For RISC-V and Cortex-M-not-3, triples are known and have worked in some
configuration, but do not work at the moment and stay disabled until the
reference platforms (native, M3) have been established well.
- Add the new EXTERNAL_BOARD_DIRS variable that can contain a space separated
list of folders containing external boards
- Introduce $(BOARDDIR) as shortcut for $(BOARDSDIR)/$(BOARD)
- Map the existing BOARDSDIR to the new approach
- If BOARDSDIR is provided by the user, it will be added to
EXTERNAL_BOARD_DIRS for backward compatibility. (And a warning is issued
to encourage users migrating to EXTRA_BOARDS.)
- BOARDSDIR is updated after the board is found to "$(BOARDDIR)/..".
- Useful for `include $(BOARDSDIR)/common/external_common/Makefile.dep`
- Provides backward compatibility
This adds a new subdirectory called `fuzzing/` which will contain
applications for fuzzing various RIOT network modules in the future.
This subdirectory is heavily inspired by the `examples/` subdirectory.
The fuzzing applications use AFL as a fuzzer. Each application contains
Makefiles, source code, and an input corpus used by AFL to generate
input for fuzzing.
Introduce a new variable 'BOARDSDIR' to use when referencing the base
boards directory.
This is a transition to allow defining external boards while still using
the `RIOT/boards` directory for like `boards/common` for example through
'RIOTBOARD'.
When CCACHE_BASEDIR variable is set, ccache rewrites absolute paths into
relative paths before computing the hash that identifies the compilation
for all the paths under that directory.
The problem is that those paths are also used when the compiler is
called, so the generated dependency files (*.d) will have a relative
path to the object files, and thus, it will not match our rule for
compiling (we use absolute paths). As dependency files define the
targets this way, any change on its dependencies (e.g. an included
header file) will not re-trigger a build.
CFLAGS_CPU is required for 'pkg/openthread'. So declare it as a global
compilation variable.
The goal is to move the export to `makefiles/vars.inc.mk` and remove the
local exports that could be in boards/cpu/arch.
Document `BINFILE` in the same ways as `HEXFILE`.
The file does not need to be exported so no reason to do it though.
It also adds it in the `info-build` output in the same way as `HEXFILE`.
This variable is only used for the term recipe (and maybe for flashing). They
should not be evaluated if they are not needed and the user should not see a
warning that the port is not set if he does not use port (for example in make
all.)
