My usage of TI-specific toolchains was dropped in favour of using Yocto or Buildroot directly, as the TI pre-packaged toolchains have a slow release/support cycle. I considered these Dockerfiles deprecated as of March 31, 2022 - and they were removed on June 12, 2024
Support was been dropped in favour of the similar (and more consistently named) robotpajamas/gcc-arm-none-eabi starting on March 31, 2022 - and the associated Dockerfile was removed on June 12, 2024.
