• Xilinx QEMU 2021.1

Release Notes

• general:

  • Linux Zephyr SDK binaries now link against glibc 2.28 and require a host
    operating system with glibc 2.28 or above (RHEL 8+, Debian 10+, Ubuntu
    20.04+).
  • Arm toolchain (arm-zephyr-eabi) now includes ARMv7-R big-endian
    multi-libs.
  • Added Xtensa sample_controller32 toolchain
    (xtensa-sample_controller32_zephyr-elf).
  • Added AMD ACP 6_0 toolchain (xtensa-amd_acp_6_0_adsp_zephyr-elf.).
  • Added Intel ACE30 PTL toolchain (xtensa-intel_ace30_ptl_zephyr-elf).
  • Added NXP HIFI1 toolchain (xtensa-nxp_rt700_hifi1_zephyr-elf).
  • Added NXP HIFI4 toolchain (xtensa-nxp_rt700_hifi4_zephyr-elf).
  • On Windows, OpenOCD installed under the "Program Files" directory is now
    used by default when ZEPHYR_TOOLCHAIN_VARIANT is set to zephyr. Note
    that OpenOCD is not currently available as part of Zephyr SDK on Windows.

• gdb:

  • Python scripting-enabled GDB (gdb-py) now links against Python 3.10, which
    is the minimum Python version supported by Zephyr.

• gcc:

  • Fixed incorrect C library header usage when compiling libstdc++ for
    newlib-nano and picolibc in non-Linux toolchains. This fixes the "undefined
    reference to _impure_ptr" errors when building Zephyr C++ applications
    with macOS and Windows toolchains.
  • Fixed insufficient argument checking in Secure state entry functions in
    software using Cortex-M Security Extensions (CMSE). For more details, refer
    to the CVE-2024-0151.
