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].
