Included Components

Toolchains

• Binutils 2.43.1 with Zephyr patches
• GCC 14.3.0 with Zephyr patches
• GDB 16.2 with Zephyr patches
• LLVM 19.1.7 with Zephyr patches
• Picolibc 1.8.10

Host Tools

• BOSSA 1.9.1-14-g3532de8
• DTC 1.6.0
• OpenOCD 0.12.0 with Zephyr patches
• Updated QEMU to 10.0.2 release.
• Updated Xilinx QEMU to 8.1.0 release (part of Xilinx tools v2024.2 release).
• Added "legacy QEMU" that is equivalent to the "QEMU 7.0.0 with Zephyr

Release Notes

• general:

  • Update GCC to 14.3
  • Picolibc is the default and only C library
  • C Library is now built with both speed and size optimization
  • Added Clang/LLVM 19.1.7 toolchain with Arm and RISC-V architecture support.
  • Introduced Clang/LLVM toolchain distribution bundle
    (zephyr-sdk-VER_HOST_llvm).
  • Renamed existing "full" GNU toolchain distribution bundle to
    zephyr-sdk-VER_HOST_gnu.
  • Windows executables now link against UCRT, which supports Unicode.

• cmake:

  • Restructured toolchain CMake script to support GNU and LLVM toolchains.
    This requires Zephyr 4.2.0 or above (or the latest collab-sdk-dev).
  • Zephyr SDK GNU toolchain now declares TOOLCHAIN_HAS_GLIBCXX.
  • Zephyr SDK LLVM toolchain now declares TOOLCHAIN_HAS_LIBCXX.
