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].

Hello!
I mentioned a few weeks back that I had some doubts on the difference
between this override:
SRCREV_kernel = "5821a5593fa9f28eb6fcc95c35d00454d9bb8624"
and this one:
SRCREV_kernel_juno = "5821a5593fa9f28eb6fcc95c35d00454d9bb8624"
The following is the definition in the kernel recipe itself:
SRCREV_kernel = "3d77e6a8804abcc0504c904bd6e5cdf3a5cf8162"
Turns out that with _only_ the first override in local.conf (without
MACHINE), the kernel uses the right SRCREV but Perf uses the one from
the recipe; I have to include the second override (with MACHINE) so
that Perf can use the right SRCREV.
Does anyone have a pointer that could shed more light on that subject?
Thanks and greetings!
