Here you can find conan packages for the ARM GNU Toolchain packages used by libhal project.
conan create all --version 12.2.1
conan create demo/picolibc_test_pkg --version 12.2.1
conan build demo -pr demo/profile
The demo package will not succeed, but what is more important is that the
arm compiler and picolibc flags are present in the commands. They can be exposed
by adding VERBOSE=1
in front of the command.
