Toolchains

Host Tools

  • BOSSA 1.9.1-14-g3532de8
  • DTC 1.6.0
  • OpenOCD 0.11.0 with Zephyr patches
  • QEMU 7.0.0 with Zephyr patches
  • ARC QEMU 2022.08.04
  • Xilinx QEMU 2021.1

Release Notes

  • general:

    • Added Intel ACE15 MTPM toolchain (xtensa-intel_ace15_mtpm_zephyr-elf).
    • Added Intel TGL ADSP toolchain (xtensa-intel_tgl_adsp_zephyr-elf).
    • Removed Intel APL ADSP toolchain (xtensa-intel_apl_adsp_zephyr-elf).
    • Removed Intel S1000 toolchain (xtensa-intel_s1000_zephyr-elf).

  • cmake:

    • Fixed the Zephyr SDK CMake package registration failure when the setup script is run by a non-root user and the SDK is located in a directory that is not writable by the user.

  • binutils:

    • Fixed ARM MVE VCVTNE instruction misinterpretation bug.

  • openocd:

    • Disabled ARC_SEC core debugging support to work around the GDB connection timeout issue (refer to the GitHub issue #631).

  • newlib:

    • Enabled newlib-nano for all targets except Xtensa. Note that newlib-nano is disabled for the Xtensa targets because of a memset bug causing crashes (refer to the GitHub issue #660).

  • picolibc:

    • Updated to Picolibc 1.8.1 release.

Host Tools

  • BOSSA 1.9.1-14-g3532de8
  • DTC 1.6.0
  • OpenOCD 0.11.0 with Zephyr patches
  • QEMU 7.0.0 with Zephyr patches
  • ARC QEMU 2022.08.04
  • Xilinx QEMU 2021.1

Release Notes

  • general:

    • Fixed "ERROR: Unsupported host operating system" when running the distribution bundle setup script on the Linux distros that report the OSTYPE of linux instead of linux-gnu (e.g. Alpine, SUSE).
    • Changed the glibc version for the host tool binaries from 2.32 to 2.27 (default in Ubuntu 18.04) in order to improve compatibility with the older Linux distros.

  • gcc:

    • Fixed the missing C99 math function declarations in the libstdc++ header for the AArch64, RISC-V and x86-64 targets.
    • Disabled the compiler level support for the thread-local storage on the targets without the Zephyr-side thread-local storage support to prevent users from arbitrarily enabling it.
    • Updated the AArch64 toolchain libraries to build with the -moverride=tune=no_ldp_stp_qregs flag that disables the GCC optimisation that generates the ldp and stp instructions with the Advanced SIMD register operands for consecutive 32-byte copy operations, which can be expensive because it activates the Advanced SIMD context for a thread and can incur a massive context switching overhead due to its large size.
    • Updated the ARC toolchain libraries to build with the -mtp-regno=26 flag to ensure that the toolchain library functions do not overwrite the thread- local storage pointer register when the thread-local storage support is enabled.
