There are some objects in the FVP binary that are assembler source and fail to declare what permissions the stack needs to have, so GCC falls back to assuming that the final binary needs an executable stack. glibc 2.41 (as now used in uninative) introduces changes here[1]: whether to have an executable stack or not when the binary doesn't specify a need (defaults to executable, but this is a tunable), and any binaries that are dlopen()ed that require an executable stack will fail. Thus, some FVPs on some platforms (notable, fvp-base-a-aem on x86-64) now fail on startup: libarmctmodel.so: cannot enable executable stack as shared object requires: Invalid argument Luckily the solution here is to simply clear the executable bit, as an executable stack is not actually needed. Until a new release of the FVP is made we can fix the binary in our package using execstack.

Introduction
This repository contains the Arm layers for OpenEmbedded.
-
meta-arm
This layer contains general recipes for the Arm architecture, such as firmware, FVPs, and Arm-specific integration.
-
meta-arm-bsp
This layer contains machines for Arm reference platforms, for example FVP Base, N1SDP, and Juno.
-
meta-arm-toolchain
This layer contains recipes for Arm's binary toolchains (GCC and Clang for -A and -M), and a recipe to build Arm's GCC.
Other Directories
-
ci
This directory contains gitlab continuous integration configuration files (KAS yaml files) as well as scripts needed for this
-
kas
This directory contains KAS yaml files to describe builds for systems not used in CI
-
scripts
This directory contains scripts used in running the CI tests
Mailing List
To interact with the meta-arm developer community, please email the meta-arm mailing list at meta-arm@lists.yoctoproject.org Currently, it is configured to only allow emails to members from those subscribed. To subscribe to the meta-arm mailing list, please go to https://lists.yoctoproject.org/g/meta-arm
Contributing
Currently, we only accept patches from the meta-arm mailing list. For general information on how to submit a patch, please read https://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded
E-mail meta-arm@lists.yoctoproject.org with patches created using this process. You can configure git-send-email to automatically use this address for the meta-arm repository with the following git command:
$ git config --local --add sendemail.to meta-arm@lists.yoctoproject.org
Commits and patches added should follow the OpenEmbedded patch guidelines:
https://www.openembedded.org/wiki/Commit_Patch_Message_Guidelines
The component being changed in the shortlog should be prefixed with the layer name (without the meta- prefix), for example:
arm-bsp/trusted-firmware-a: decrease frobbing level
arm-toolchain/gcc: enable foobar v2
Releases and Release Schedule
We follow the Yocto Project release methodology, schedule, and stable/LTS support timelines. For more information on these, please reference: https://docs.yoctoproject.org/ref-manual/release-process.html https://wiki.yoctoproject.org/wiki/Releases https://wiki.yoctoproject.org/wiki/Stable_Release_and_LTS
Reporting bugs
