Subject: [Buildroot] [git commit branch/2020.02.x] package/xenomai: disable cobalt for armv8
Date: Wed, 10 Feb 2021 19:53:23 +0100 [thread overview]
Message-ID: <20210210183732.13C17807E9@busybox.osuosl.org> (raw)
commit: https://git.buildroot.net/buildroot/commit/?id=ee6ae5e7328887dd1c56e5bec5091438dd86b977
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2020.02.x
When a armv8 target is used in 32bits mode, xenomai fail to detect the
ARM architecture and abord the build. (__ARM_ARCH_7A__ is not defined
for armv8 cpus).
There are no autobuilder failures for this issue since cobalt is never
selected, but the following defconfig:
BR2_arm=y
BR2_cortex_a53=y
BR2_ARM_FPU_NEON_VFPV4=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_PACKAGE_XENOMAI=y
BR2_PACKAGE_XENOMAI_COBALT=y
This was initialy reproduced using the raspberrypi3_defconfig with
Xenomai package with cobalt selected.
In order to use Xenomai on raspberrypi3 in 32 bits mode, one has to
select BR2_cortex_a7 instead of BR2_cortex_a53 (see a13a388dd444).
