Firmware build configuration |
You need the following software in order to compile the firmware:
- Make
- GCC+binutils for arm-none-eabi - any version supporting C17 and C++17.
- Ruby - any recent version (>=2.5-ish) should be fine.
- nrfutil - version 6.1.6 or newer will work.
With those programs installed, simply run make debug -j4
to run a build.
build.yaml
is where the build is configured. You should never need to edit
the makefiles directly.
The path to each "component" of the project is listed in the components:
section of build.yaml
. In each "component" folder, there is a component.yaml
file that lists the source files and include directories provided by that
component.
Modify sure the compilerPath
field in c_cpp_properties.json
is
When you run make
, the makefiles (with the help of some ruby scripts) will
automatically update the includePath
and defines
fields in
c_cpp_properties.json
.
