First edit your alire.toml file and add the following elements:
Add embedded_nrf54l_app in the dependency list:
[[depends-on]]
embedded_nrf54l_app = "*"
Then edit your project file to add the following elements:
"with" the run-time project files:
with "runtime_build.gpr";
with "ravenscar_build.gpr";
Specify the Target and Runtime attributes:
for Target use Runtime_Build'Target;
for Runtime ("Ada") use Runtime_Build'Runtime ("Ada");
specify the Linker switches:
package Linker is
for Switches ("Ada") use Runtime_Build.Linker_Switches & ("-Wl,--gc-sections");
end Linker;
Note that the linker switch -Wl,--gc-sections is optional, but its use is
recommended since it reduces the final size of the executable by removing
unused code.
