meta-linaro support for ARM GCC 9.2-2019.12 toolchain - OpenEmbedded

23 Jan 2020


      Hi Everyone,
We are pleased to announce that support for ARM GCC 9.2-2019.12 [1]
toolchain has been added in meta-linaro [2].
- Support for ARM GCC 9.2 toolchain built from source, steps to use it:
      - Add <path-to-meta-linaro-repo>/meta-linaro-toolchain/ to BBLAYERS
      in conf/bblayers.conf.
      - Configure: GCCVERSION = "arm-9.2" in conf/local.conf.
- Support for prebuilt ARM GCC 9.2 toolchain, steps to use it:
      - Add <path-to-meta-linaro-repo>/meta-linaro-toolchain/ to BBLAYERS
      in conf/bblayers.conf.
      - Configure: TCMODE = "external-arm" in conf/local.conf.
      - For AArch64 (eg. qemuarm64 machine in poky distro)
         - Configure: EXTERNAL_TOOLCHAIN =
         "<installation-path>/gcc-arm-9.2-2019.12-x86_64-aarch64-none-linux-gnu"
in
         conf/local.conf.
      - For AArch32 (eg. qemuarm machine in poky distro)
         - Configure: EXTERNAL_TOOLCHAIN =
         "<installation-path>/gcc-arm-9.2-2019.12-x86_64-arm-none-linux-gnueabihf"
         in conf/local.conf.
Distro testing:
===========
- poky distro (branch: zeus, machines: qemuarm and qemuarm64)
      - Build and boot tested.
- RPB distro (branch: zeus, machine: dragonboard-410c)
      - Build and boot tested.
- World builds (branch: zeus, machines: qemuarm and qemuarm64) for
   following layers:
      - poky/meta
      - poky/meta-poky
      - poky/meta-yocto-bsp
      - meta-openembedded/meta-oe
      - meta-openembedded/meta-python
      - meta-openembedded/meta-networking
Known issues:
===========
- mariadb build failure with ARM GCC 9.2 toolchain built from source:
      - Recipe fix patch [3] accepted in OE upstream.
- Native tools dependency issues seen with multiple recipes (psmisc,
   xclock, ndisc6, dovecot, man-db, drbd-utils and unbound) when using
   prebuilt ARM GCC 9.2 toolchain.
      - Fixes posted in OE upstream [4] [5].
