Building packages for TriCore

Warning

This feature is experimental and subject to breaking changes. See the Conan stability section for more information.

TriCore is an embedded microcontroller architecture used in multiple domains such as automotive. There are multiple compilers for TriCore, some of which can be found here. There are also gcc implementations for TriCore; this is what we will be using in the examples on this page.

Since Conan 2.7 there is some built-in support for this architecture:

  • The default settings.yml contains architectures: 'tc131', 'tc16', 'tc161', 'tc162', 'tc18'

  • CMakeToolchain defines CMAKE_SYSTEM_NAME=Generic-ELF and CMAKE_SYSTEM_PROCESSOR=tricore for these architectures

  • The compiler flags -m<architecture>" are injected as compiler and linker flags in CMakeToolchain and AutotoolsToolchain

That means that it is possible to define a profile like:

tricore.profile

  1. [settings]
  2. os=baremetal
  3. arch=tc162
  4. compiler=gcc
  5. compiler.version=11
  6. compiler.cppstd=20
  7. compiler.libcxx=libstdc++11
  9. [options]
  10. *:fPIC=False
  11. *:shared=False
  13. [conf]
  14. tools.build:compiler_executables={"c":"tricore-elf-gcc","cpp":"tricore-elf-g++"}

This assumes the compiler is installed in the system path, and its executables are called tricore-elf-gcc and tricore-elf-g++. And then, cross-build and create a package for TriCore using this profile, for example the default cmake_lib:

  1. $ conan new cmake_lib -d name=mypkg -d version=0.1
  2. $ conan create . -pr=tricore.profile

Note

  • This support is new and experimental. Please create a ticket in https://github.com/conan-io/conan/issues for any feedback or issues

  • Linking applications (like if using conan new cmake_exe) requires a specific linker script, definition of entry-points, etc. Trying to build it as above will produce linking errors. We will try to add further examples for this case.
